[HOW-TO][EXYNOS/SNAPDRAGON] Root S20 series and upgrade firmware - Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News

Applicable Models:
All Exynos models including but not limited to:
SM-G980F or SM-G980F/DS (S20)
SM-G981B or SM-G981B/DS (S20)
SM-G985F or SM-G985F/DS (S20+)
SM-G986B or SM-G986B/DS (S20+)
SM-G988B or SM-G988B/DS (S20 Ultra)
All BL-unlockable Snapdragon models including but not limited to:
SM-G9810 (S20, Hong Kong, Taiwan, China mainland)
SM-G9860 (S20+, Hong Kong, Taiwan, China mainland)
SM-G9880 (S20 Ultra, Hong Kong, Taiwan, China mainland)
SM-G981N (S20, Korea)
SM-G986N (S20+, Korea)
SM-G988N (S20 Ultra, Korea)
Japanese model (SC-*) also use Snapdragon but I can't not confirm that its bootloader is unlockable.
It is known that bootloader can NOT be unlocked on U.S. models (U/U1) .
Frequently used key combinations of S20 series:
FORCE REBOOT: Hold "Volume Down" and "Bixby/Power" button.
DOWNLOAD MODE: With the phone off, hold "Volume Down" and "Volume Up" button, connect your phone to a computer via a cable. Release the buttons after you see the "Warning" screen and then press "Volume Up"
RECOVERY MODE: With the phone off, hold "Volume Up" and "Bixby/Power" button.
Some facts:
1. S20 series uses dynamic partition which means there is only one "super" partition (instead of "system", "vendor", "product").
3. S20 series uses A-only partition which means there is only one set of system partition.
3. S20 series uses 2 stage init (2SI).
4. KNOX will be tripped after you flash a custom image. As a result, Samsung Pay and Secure Folder will become permanently (even after restore to stock firmware) unusable and your warranty may be voided. However, many jurisdictions including the European Union has law mandating manufacturer to provide hardware warranty even if user modifies the software.
5. Samsung devices are almost impossible to hard brick (render the device unusable without a hardware-level repair) as critical sections including the bootloader are well-protected. However, if you do things incorrectly, you may soft brick your phone, but that can usually be resolved by resetting to factory settings (wipe data and cache) or restoring to stock firmware (check out Stage 4).
Tools needed:
On your computer:
1. Odin 3.14.4 or newer
2. Samsung Android USB driver
3. SamFirm or other tools/websites to download official firmwares
4. Android Verified Boot Metadata Image with verification disabled (vbmeta_disabled.tar)
On your device:
1. Magisk Manager
Stage 1: Know your model and carrier code (CSC)
1. Open "Settings"
2. Go to "About phone" -> "Software information"
3. Pay attention to "Service provider SW ver."
4. Starting with "SM-", for example "SM-G9810", that's the model of your phone.
5. Immediately after that, there are two 3-letter code, for example "OZL_CHC". The second 3-letter code "CHC" is your CSC.
6. Remember your model and CSC.

}
Stage 2: Unlock the bootloader
WARNING: ALL data on your device, including apps, settings and files in internal storage, will be lost. You do not need to repeat this if you didn't re-lock your bootloader.
1. Open "Settings"
2. Turn on "Developer mode" by going to "About phone" -> "Software information" and pressing "Build number" for several times.
3. Go to main menu of "Settings" and at the bottom you will find "Developer options"
4. Go to "Developer options". You will find a toggle "OEM unlocking". Turn it on.
5. Skip to step 8 if your device reboots to "Unlock bootloader?" screen. Make sure the toggle is on and then turn off your phone.
6. With the phone off, hold "Volume Down" and "Volume Up" button, connect your phone to a computer via a cable. (don't use charging only cables)
7. Release the buttons after you see the "Warning" screen. Then, hold the "Volume Up" button.
8. You will see "Unlock bootloader?" screen. Proceed and unlock your bootloader by pressing "Volume Up" button.
9. Your device will be reset to factory settings. Proceed with the Setup Wizard. Only connect to network via Wi-Fi or cellular and skip everything else. (to save time as data will be cleared again later.)
10. Repeat step 1-4 to validate that "OEM Unlocking" is on. If it is not, turn it on.
11. Repeat step 6.
12. Release the buttons after you see the "Warning" screen. This time, press (not hold) the "Volume Up" button.
13. You will see "Downloading" screen. On the top left, there are some important info.
14. Pay attention to "OEM LOCK" and "REACTIVATION LOCK". If both of them are "OFF", you have unlocked the bootloader.
Stage 3: Disable Android Verified Boot
1. Reboot to DOWNLOAD mode. If you are already in the download mode, skip to step 2.
2. Download Odin 3.14.4 or newer and make sure Samsung USB drivers are installed.
3. Open Odin and put the vbmeta_disabled.tar into USERDATA slot and click "Start"
4. Your device will reboot but it will not boot into system as vbmeta signature has changed.
5. Your device will reboot into RECOVERY mode automatically and prompt "You have to reset your device to factory settings". Use "Volume Up" or "Volume Down" button to move and "Power/Bixby" button to select. Confirm and reset the device to factory settings.
6. This is the last time the data on the device has to be cleared. Afterwards, if you don't re-lock bootloader or re-enable the Android Verified Boot, you will not lose your data. Be aware, a stock firmware package contains a Android Verified Boot Metadata Image (vbmeta.img) with verifications enabled. You will need to flash the vbmeta_disable image (put into USERDATA slot) along with the stock firmware (use BL, AP, CP, CSC slots) to make sure AVB is not re-enabled and the data is preserved.
View attachment 4990053
With bootloader unlocked and AVB disabled, it is now possible to boot modified images on the device.
If a recovery is available and you don't want to go through the process of downloading official firmware, go to #2.
You can also download a KERNEL TAR archive of your version here:
Exynos: https://github.com/jesec/proprietary_vendor_samsung_xyzs/releases
Snapdragon: https://github.com/jesec/proprietary_vendor_samsung_xyzq/releases
and then skip to Step 6.
Stage 4: Obtain the official firmware and upgrade
1. Open SamFirm
2. Type in your model and your region (CSC) and click "Check Update"
3. "Download" and you will get a zip file.
View attachment 4990061
4. Extract it and you will get 5 files (AP, BL, CP, CSC and HOME_CSC). All files are in tar format and can be opened by 7-Zip, WinRAR or other software.
5. Check the version code, for example (G9810ZCU1ATD1). The last 4 letters (ATD1) indicates the version of the firmware. If the version is the same as your current firmware, skip to Stage 5.
Your data will be preserved if you do it right but it is good to have a backup.
6. Open Odin on your computer and reboot your device to DOWNLOAD mode.
7. Put AP, BL, CP files in their Odin slots. It takes time to verify the firmware so be patient.
8. Put HOME_CSC file in CSC slot. Be careful here. Unlike AP, BL, CP slots, you should NOT use CSC file for CSC slot. Instead, you should use HOME_CSC file. CSC file contains partition table (PIT) which will erase all your data.
9. Put vbmeta_disabled file in USERDATA slot so AVB remains disabled and your data preserved.
10. Click "Start" and wait for it to finish. Allow the device to boot into system to complete the upgrade process. Do NOT interrupt/disconnect phones/hold button. It needs to complete the process without interruption or strange BUGs may appear.
View attachment 4990063
Stage 5: Extract boot (kernel) image from firmware
If you are having trouble creating tar file, you can skip to Stage 6. (NOT RECOMMENDED as AP is basically full system image. It is huge (takes long time to flash/process) and Magisk may misbehave.)
1. Extract boot.img.lz4 from the AP file.
2. Use 7-Zip to create a tar archive which contains boot.img.lz4 only. (or "tar cvf boot.tar boot.img.lz4")
View attachment 4990065View attachment 4990067View attachment 4990069View attachment 4990071
Stage 6: Patch the boot (Kernel) image via Magisk
1. Transfer the tar archive (or the AP file if you skipped stage 5) to your phone.
2. Open Magisk Manager.
3. Click top-right "Install" button
4. Make sure "Recovery Mode" is off in Options.
5. Click "Next" and select "Select and Patch a File" in Method.
6. Select the file you transferred to your phone in step 1.
7. Click "Next" and "LET'S GO".
8. Transfer the patched file (in Download/magisk_patched.tar) to your computer
9. Reboot the device to DOWNLOAD mode.
10. Open Odin, put patched file to AP slot and then click "Start".
11. After reboot, Magisk is installed and you will have the root access.
HOW TO upgrade the firmware
Repeat stage 4-6.

Other Methods:
You still need to unlock bootloader and disable AVB. (check Stage 2-3)
Recovery Magisk installation:
1. Open Odin on your computer.
2. Reboot your device to DOWNLOAD mode.
3. Put the recovery TAR flashable into AP slot.
4. Click start.
5. Use Volume Up + Power to reboot into recovery mode.
6. Install Magisk via recovery.
My recovery usually includes Magisk in "Select from root" -> ".builtin" folder. Or you can sideload the ZIP flashable of your choice via adb or https://flash.jesec.io/.
Flash pre-patched boot (Kernel) image:
Basically others have done stage 4-6 for you. Be aware that it is always safer to DIY.
You are welcomed to share your patched image to the community by replying to this thread.
Naming convention: model + firmware version (last four letters of build number) + magisk version .tar
1. Make sure that the model and firmware version of the pre-patched image is the exact SAME as yours.
2. Open Odin on your computer.
3. Reboot your device to DOWNLOAD mode.
4. Put pre-patched image into AP slot.
5. "Start"

Some Interesting Things:
Change your CSC (carrier code):
You have to root your device. There might be some secret codes to trigger the menu without root, though.
Note that you can only change it to carrier configurations already included in your firmware.
WARNING: Your device will be reset to factory settings.
In a local terminal, type:

Android Verified Boot prevents images which are not signed by Samsung to boot on the device. Obviously we don’t have Samsung’s private key and we need to modify images to obtain root access. So it has to be disabled.

You must have done it somewhere in the process. Magisk will patch vbmeta.img for you if you give it a tar archive.

I'm rooted for weeks now without this... can you explain more in detail what this is for? Why is it advised from you to do this step? maybe in form of examples? like I said rooted without doing this and had no issues so far.

Magisk Root on Snapdragon based SM-G9860 S20+?
First of all, thanks for putting this guide together - very useful. I did want to share my experience following these instructions.
Everything went well until Stage 6 where I installed the Magisk patched AP file. The AP file was successfully patched with the latest canary Magisk and it also installed properly in Odin (did the full AP file and not the boot image since that encountered errors while trying to repack for some reason).
The problem is that when I reboot, No Magisk installed and No root...
I tried a factory reset just to confirm but same outcome. I did use the same AP file that was used to flash the phone as well.
Anyone successfully root and install Magisk on the Snapdragon based SM-G9860 S20+ (with latest Hong Kong firmware)? I suspect it has something to do with the Magisk not being able to handle the unlocked snapdragon based phones yet (it was like that for the Galaxy 10+ last year - took an extra month to come up with a Magisk branch that was able to handle the phone). I'm also following this thread for Snapdragons based S20 but it doesn't seem to have too many details yet
Cheers

My Snapdragon S20 has been rooted with Magisk. I think probably it has problem patching the full AP file. In that case, I recommend you to research how to pack a tar file. I don't recommend you to patch the full AP as it is huge.
Also be aware that all patched file is located in /sdcard/Download and named magisk_patched.*. It is NOT in-place patch. You might accidentally use the unpatched file.

So I tried to apply this tutorial to update my phone SM-G981F
And it can't boot. it finish in failsave recovery :
"Can't load ndroid system. your data may be corrupted..... please perform a factory reset...."
I really would like to avoid it... I flashed vbmeta_disabled.tar but no GO...
I was already rooted with Magisk patch on ATCH rom...
Edit : wiped...

As it finishes flashing firmware hold volume buttons as it reboots. Then flash patched boot.img and reboot. Worked for me going from ATCH to ATCT today.

Thanks for the help. I did try patching the TARed (using 7zip) boot.img.lz4 file but for some reason it just refuses to "repack" from within Magisk (see screen capture attached)- I'm not sure if anyone experienced this or if I'm overlooking something.
Also tried to reformat everything with the Chinese firmware instead of HK (it was a little more recent) but I got the same results. Oddly the full AP file seems to patch fine in Magisk but never produces the expected results (no Magisk installed, no root).

I had the same issue... I used a tool (lz4_win64_v1_9_2) to uncompress lz4 format... I kept it just as boot.img and packed in boot.tar file and it worked.
Just for info, 7-zip built wrong tar file (don't ask me why...)... I had to use cygwin for it (or a linux if you have)

That's expected.
From Android 10, encryption keys are tied to AVB key (stored in vbmeta). By disabling AVB, you changed the AVB key from Samsung's to none. Though, if I remember correctly, some old versions have security loophole that allows you to boot a patched kernel even if AVB key is intact (recovery is still protected however). That's actually a serious breach of this additional integrity assurance. (your sensitive data is still safe nonetheless as there is a customer key tied to your password/pattern/etc)

That should not happen. Here is a screenshot if things are done right:
Make sure you pack the TAR right (see OP for a screenshot of boot.img.lz4.tar) and the file you transfer to your device is the TAR file (boot.img.lz4.tar if you don't change the file name).
Plus, maybe check if Magisk version is right. Make sure you use the Canary builds.

Root or ROMs for 2019 Tab A 8.0" (SM-P200/5)

I realize this may be quite hard to answer but hopefully someone has some idea
I'm really tempted by the new galaxy tab a 8 with s pen (sm-p200/sm-p205). It's the perfect size for quick note taking
Thing is, I really want root and custom roms for it, does anyone have any thoughts as to how likely these are to eventuate? It shares the same chipset (exynos 7885) as the 2018 Galaxy A8 phone which has been rooted
Is this device likely to get root or custom rom support?
It seems we have magisk root here :
https://blog.gsm-social.com/2019/07/p205-u1-9-and-magisk/
But I don't understand Arabic. Can anyone check this site?
Could someone update on any feedback if they managed to get the P200/205 rooted?
Thanks a lot for the info
I've actually try this method on my P205 (China/ Hong Kong version) but could not make it work. It's possible that maybe works on an international version of the P205 or on the P200. Has anyone else tried this method with any success?

Hi,
successfuly rooted mine. It is the malaysian version of the tab. As this is a new device from 2019 with System-as-Root and Android 9.0 Magisk must be installed to the recovery partition. Everytime you reboot you must press the keycombination for booting from the recovery partition. ( Vol Up + Power).
Use the tutorial from the readme on the magisk github page

Hi,
i have the LTE Version SM-P205. As it arrived it had an old firmware so I first updated to the current stock Firmware P205DXU2ASH2 with the normal Samsung Update.
I downloaded the correspondending firmware files again for magisk patching with samfirm tool or if you or prefer from the usual samsung firmware download pages.
As i have a CSC from malaysia i took the XME CSC Firmware. From there on you can just fellow the magisk tutorial. Hopefully someone compiles a twrp recovery as firmware sources are available. So now i am on stock rooted firmware P205DXU2ASH2 .
I am using the LTE Version here in germany without any problems.

Thanks again for the info. I will try follow the same steps and attempt to root again. I've had endless Samsung devices and this is the first time I am having problems trying to get one rooted.. Then again this is a much different process than the usual and we don't have Recovery yet. Given the limited sales and interest in this Tab (which is really a shame), probably there won't be too much development around it. This is actually the best price/features Tab Samsung makes now and the perfect form factor/size. If only the hardware was a bit faster and the camera a bit bigger.. but hey, can't have everything, haha
Thanks again for sharing the info, much appreciated

You know, I have received lots of PM regarding root as no one seems to be successful at it. You should start a new thread, call it something like "SM-P205 ROOT ACHIEVED" and post a step-by-step guide on how you did it. Not many people are following this thread here and news of root for this Tab will make thousands of people very happy worldwide.
If you have the time, you should do it. The whole community here appreciation is guaranteed

Awesome, I'll check it out now
Just bought the wifi variant of this tablet here in Germany too.....Seems to be a good 8" alternative. Looking forward to installing twrp and a Lineage ROM. Any news for that?
samsung unlockBL downgraderoot AutoBootCharge autoSd3HrIdle Charge to 65%
It is sharing of experience only without any liability or warranty.
Why: I use the tab very rarely but in critical requirement, I am getting it in discharged condition when i needed. Good news is that , in off condition it consumes around 1% per 10 days. I did not want to root it, but this tab at least shoud have have scheduled shutdown like other makes. The battery protect mode does not function properly. However thanks to Samsung for leaving the facility to unlock the Bootloader, rooting etc for advanced users (I feel definitely it has the capability to lock fully like apple )
Pre requirements
1. Samsung Tab A 2019 P200 (I have no experience on other models) charged more than 50%
2. Usb cable
3. Samsung USB Drivers
4. Windows 10 PC with UPS
5. Firmware suitable to your phone / region
6. Odin3-v3.14.4
7. 7Z ZS
8. Magisk Manager
9. Root explorer
I. Unlocking Bootloader
Normally I wouldn’t provide instructions for this, but since things had changed drastically from previous Samsung devices, and there are some caveats, I figure this would be helpful.
The following worked for me
• Installed Samsung USB driver on PC
• Allow bootloader unlocking in Developer options → OEM unlocking
• Disconnect the USB cable
• Power off the device
• Press and hold Volume Up & Down keys
• Insert USB cable
• Long press Volume up key
• Press Volume up ( yes) to unlock BootLoader
Just when you think the bootloader is unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will reject any unofficial partitions before VaultKeeper explicitly allows it.
• Go through the initial setup. Skip through all the steps since data will be wiped again later when we are installing Magisk. Connect the device to internet in the setup!
• Enable developer options, and confirm that the OEM unlocking option exists and grayed out! (yes it happened in my case) The VaultKeeper service will unleash the bootloader after it confirms that the user has the OEM unlocking option enabled.
• Your bootloader now accepts unofficial images in download mode.
II. Downgrade Flash instructions
1. Extract (unzip) the Samsung firmware file. Recommended using 7-Zip ZS
2) Install Samsung USB driver on PC if already not installed
3. , Extract Odin ZIP file Odin Tool 3.14.4 Downloaded, Open Odin execute file
4.) Remove Samsung . Google etc accounts from Tab
5. Reboot Samsung phone in Download Mode (hold Power + Volume Up buttons, it will booted to Recovery, select reboot to bootloader, Downloading screen will come then plug-in cable)
6. Connect you Samsung phone and wait until you get a blue symbol with com port no in Odin
7. Add the 1 file Samsung firmware to AP/PDA or 4 files Samsung firmware (AP/BL/CP/CSC) to it's slots (for P205 it will be 5 files)
8. Make sure re-partition is NOT ticked at Options at Odin
9. Click the START button, sit back and wait few minutes
Downgrading BootLoader-Theory
Downgrading BootLoader is Not possible unless you modify the BL….. .tar.md5 by removing the .bin files in it, then tar it up and flash in odin (- NOT TRIED).
The secure bootloader (sboot.bin) won't allow the downgrade of itself. you can't downgrade because the bootloader is protected by Rollback Prevention, So apparently I can only install firmware files which come with the same Bootloader.
We need to know what your current "Build Number" is on the phone. You also can't downgrade to other bootloaders that are lower then your current one, so if you're on bootloader 5 you need to use the Oreo bootloader 5 version firmware or it will not work. (Bootloader # is the 5th spot from the right.
Rollback Prevention (RP)
Rollback Prevention blocks the device from loading or flashing an approved but old version of boot components. Old versions of software may contain known vulnerabilities that attackers can exploit. Rollback prevention checks the version of the bootloader and kernel during both boot and updates, and blocks these processes from continuing if versions are unacceptably old. The lowest acceptable version of the bootloader is stored in secure hardware fuses when the device is flashed, and the lowest acceptable version of the kernel is stored in the bootloader itself. Whenever a vendor-applied update occurs, the lowest acceptable version can be incremented in the fuses. Because this value is kept in fuses, it cannot be decremented even through physical tampering. Rollback Prevention fuses are set at manufacturing time in the Samsung factory to prevent old firmware versions from overwriting newer ones.
Present version on device: P200ZHU2ASK2 (Settings>About Tabet>Software information>Build No XXXX XXXXXXX P200ZHU2ASK2, Service Provider SW ver ………….TGY// i.e Hongkong) , tried and failed is : P200ZHU1ASG1 , but now downgraded (bootloader is same version) P200ZHU2ASH2.
III. Rooting
Notes Installing Magisk
• Your device is non-A/B and uses system-as-root, so Magisk will be installed to the recovery partition of your device.
• Installing Magisk WILL trip KNOX (void Warranty)
• Installing Magisk for the first time REQUIRES a full data wipe, backup before continue
• You have to have your bootloader unlocked before following the instructions
Instructions on Rooting
1. Unzip the firmware P200ZHU2ASH2 on PC and copy the AP tar file to your Phone. It is normally named as AP_P200ZHU2ASH2_CL16717766_QB25581052_REV01_user_low_ship_meta_OS9.tar.md5
2. Install the latest Magisk Manager
3. In Magisk Manager: Install → Install > select and patch file> browse to location of file > tap and hold to select >open e.g AP tar file> working version / build is MagiskManager-v7.5.1.apk) (internet connection will make install button visible )
4. Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar
5. Copy the patched file to your PC with adb pull /sdcard/Download/magisk_patched.tar. Do not use MTP as it is reported to corrupt files.
It will be copied to PC at C:\Users\......\AppData\Local\VirtualStore\Program Files (x86)\Minimal ADB and Fastboot
6. Reboot to download mode, and flash magisk_patched.tar as AP in Odin, together with the BL, CP and HOME_CSC files. Never flash only an AP file, as Odin can shrink your /data file-system if you do.
Important: Uncheck “Auto Reboot” in Options !
7. Magisk is now successfully flashed to your device! But there are still several steps before you can properly use the device.
8. We now want to boot into the stock recovery to factory reset our device.
9. Disconnect the phone.
10. Full data wipe is mandatory! Do not skip this step.
Press Power + Volume Down to exit download mode. As soon as the screen turns off, immediately press the combo key (Power + Volume Up) to boot to recovery continue pressing the volume up button until you see the stock recovery screen (Not patched recovery , as it has Factory data reset, try again, view recovery logs only) as we need it.
11. Use volume buttons to navigate through the stock recovery menu, and the power button to select an option. Choose Wipe data/factory reset to wipe the data of the device.
12. This time, we can finally boot to the system with Magisk. Select Reboot system now, and immediately press the combo key (Power + Volume Up) to recovery. After seeing the bootloader warning screen (first screen), release all buttons so it can boot to the system.
13. The device will automatically reboot for the first time it boots. This is completely normal and done by design.
14. After the device is booted up, done the usual initial setup. The following steps will need an internet connection.
15. I have manually installed the APK , downloaded in step 2 and continued to the next step. The app would be a stub and it shall automatically upgrade to the full Magisk Manager when you open it.
16. Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
17. As this is a new device from 2019 with System-as-Root and Android 9.0 Magisk must be installed to the recovery partition. Everytime you reboot you must press the key combination for booting from the recovery partition. ( Vol Up + Power) but in my case it is always booting to Magisk.
Theory: Since some devices no longer use ramdisk in boot images, Magisk has no choice but to be installed in the recovery partition. For these devices, you will have to boot to recovery every time if you want Magisk. Since both Magisk and recovery lives in the same partition, what you actually end up getting when you choose to boot to recovery will be determined by how long you press volume up.
After installing Magisk in recovery:
• (Powering up normally) → (System with NO Magisk) or if required reboot phone once OS is loaded
• (OEM Recovery Key Combo) → (Splash screen) → (Release all buttons) → (System with Magisk)
• (OEM Recovery Key Combo) → (Splash screen) → (Keep pressing volume up) → (Actual recovery)
In my case (for my version of firmware) once magisk system is booted as above , every time it is loading magiskpatched system if shutdown is used (while charger is not connected ), but if we use reboot it is rebooting to Stock system- further, if we shutdown while charger is connected it is will shutting down and start charging with charging animation (means if we press power button it will boot to stock system) great advantage as stock (partially rooted?) also can be booted when required.
Additional Info
• Magisk actually patches 3 partitions on your device:
o vbmeta: replace with empty vbmeta image to disable partition verification
o boot: remove the signature of the image to prevent soft bricks
o recovery: this is where Magisk is actually installed
• Never, ever try to restore either of the 3 images mentioned back to stock! You can easily brick your device by doing so, and the only way out is to do full Odin restore following with factory reset. Just don’t do it.
• If you want to upgrade your device, never flash the stock AP tar file with the reasons mentioned above. Always pre-patch the firmware before flashing in Odin.
• If you don’t need to patch the full firmware, you can manually create a tar file with at least vbmeta.img, boot.img, and recovery.img to let Magisk Manager patch your images in the proper way.
Release Keys ( P&V+) for System with Magisk
Keep pressing volume up for Actual recovery
IV. Splash screen and warning screen change
1. Download the correct firmware of your Samsung
2. Unzip the firmware files with an extractor (winrar, etc)
3. Open the BL file WITH 7-ZIP EXTRACTOR (example) BL
4. BL_P200ZHU2ASH2_CL16717766_QB25581052_REV01_user_low_ship.tar.md5
5. Extract the param.bin.lz4 file WITH 7-ZIP EXTRACTOR
6. Open the param.bin.lz4 file WITH 7-ZIP EXTRACTOR and extract the param.bin file
7. Extract param.bin WITH 7-ZIP EXTRACTOR. All images are extracted in a folder.
8. edit logo.jpg and svb_orange.jpg or any other file suitably
9. select all files(not folder) and right click and select 7-Zip ZS Add archive > select archive format tar>ok to get param.bin.tar
10. Close 7-zip ZS, now change the name of above file from param.bin.tar to param.bin.
11. Right click on above param.bin select 7zip ZS > add archive…> select select archive format tar>ok to get param.bin.tar again
12. Change its name to BL_param.bin_only_to_change_logo (just to remind it is BL) Now we have the param.tar file ready for ODIN.
13. Open ODIN 3.13.3, start your phone in download mode, load the param.bin.tar file in the BL section and click on start.
Note: At the end of the flashing with ODIN the phone restarts showing the modified image, but it starts in recovery mode, you just have to accept restarting the phone, and it will start normally without losing data or the configuration of your Samsung Tab A P200
V. Auto Boot Charger connected once charged to more than 5 %
1. This is a bonus, if magisk is in effective condition, it will auto boot when charger is connected.
i.e. If it boots on auto when charger is connected that means that the sytem is magisk patched
(no need to edit lpm, however if we modify lpm, phone will hang at power symbol screen in non-magisk mode –to reset it, remove charger connection , press power+VolUp+VolDown simultaneously still phone restarts )
VI. Auto shutdown on 3 hours idle
1. Install Automate app
2. Import file
“Boot to on and Auto Shutdown by 3hr idle (reset by Foreground GMusicFMusicPAmp or Charge or 11 min on) V8.flo”
3. At automate settings select Run on System start up
3. Start flow
VII. Auto stop charging at preset max and restart charging preset min shutdown phone at preset battery low
1. Install latest AccA 1.0.23 app from github and connect to internet
(older beta app was changing battery % with every booting , showing fast draining without any actual drain etc, if charger is connected instead of rising battery level , it is showing as decreasing , i.e. battery sync , ghost effect issues)
Or
If above does not work uninstall AccA and connect to internet , open magisk manager >options>downloads>search for acc >install Advanced Charging Controller 2019.7.21-r1 (201907211) > install > rebotot)
Or if above is also not working properly please use battery charge limit v1.1.1 from play store (it will not have all options of AccA.
2. Configure as required like max charge 65 , re charging start level at 35 % shutdown at 5 % etc by editing config.txt file at root>data>adb>acc-data> capacity= 5, 101, 35-65 (101 not to stop intermittently between 35-65 % charging) and save
Now one can connect phone always to power source without wearing out Battery.
It my experince only and thanks and regards to all who contributed on respective sections / fields.
hi,
thx for the comprehensive instruction.
I have successfully rooting my sm-p205
I have 2 questions if u pls help me :
1. I want root my sm-p205 because I want to use tincore keymapper. but although now I have successfully rooted it, it seems that I have to set the selinux to permissive.
I have tried all I've found, from using selinuxmodechanger, selinuxswitch, or even using terminal with su 0 setenforce 0, and all not working. that selinux still enforcing.
can u pls help me how to change the selinux ?
2. if I couldnt change the selinux, than it's no use for me to still on root. Is there anyway to go back to original stock firmware and unroot ? because I read on the last instruction of magisk that I may not flash it again with usual ap file that it may make it brick ?
thx
Any custom ROM available for this tablet? I can't find one anywhere. Thanks

Xda's search bar is your best friend mate, be sure to use it before posting
Sent from my hero2lte using XDA Labs
1. Download a U8 firmware for your device which is SM-G935F. You can download it in sammobile.com , updato.com or samfw.com
2. After the download is completed, you need to extract the downloaded rom (I recommend using apps like 7zip or Winrar)
7-zip: https://www.7-zip.org/download.html
3. After you extract the file, you will be greeted with files saying
AP_XXXXXXXXXXX
BL_XXXXXXXXXXX
CP_XXXXXXXXXXX
CSC_XXXXXXXXXX
Home_CSC_XXXXXXXXX
4. Extract the AP_XXXXXXXXX with 7-zip or Winrar
5. In my case, 3 files and 1 folder were extracted which were
system.img.lz4
boot.img.lz4
recovery.img.lz4
meta-data (This is a folder)
Note: In your case, there might be different amount of files with different extensions
6. Copy "boot.img.lz4" to another folder (lets call the folder Hello for now) and rename the boot.img.lz4 to "recovery.img.lz4"
7. Make a backup of the original "recovery.img.lz4" and "boot.img.lz4" and "meta-data" and delete those files/folders
8. Copy the "recovery.img.lz4" file from Hello to your folder which contains system.img.lz4
9. Now, your folder should only contain system.img.lz4 and recovery.img.lz4 (renamed boot.img.lz4)
10. Download the Auto Tar folder
https://www.mediafire.com/file/ah20h...s.com.rar/file
11. Extract the autotar file using 7-zip or winrar
12. Copy all the content inside the autotar file and paste it to your folder containing system.img.lz4 & recovery.img.lz4 (renamed boot.img.lz4)
13. Open the Autotar application
14. Select system.lz4.img and recovery.img.lz4
15. Press on make .md5 & type the name on the box beside select files
Note: There should not be any special characters in the name, I recommend not using any spaces, numbers, capital letters or special characters like [email protected]#
16. Then, wait until it says done, usually took us around 15 Minutes
17. Open Odin, if you dont have odin download it
https://odindownload.com/download/#.Xq6i9pnBXDc
18. In Ap tab, choose the newly created .md5 file and do the same for CSC, CP & BL
19. Connect your phone to the PC in download mode
20 Then, flash
Note: If the verification fails, rename the newly created .tar.md5 file and remove .md5 from its name, then we will be left with .tar file
21. Set up your phone and before switching off/ restarting or doing anything "Special" enable OEM unlock, or charge your phone if it has less battery, which was the issue in my case
22. Restart your phone and you will be greeted with No Command screen. The first time I saw that again, I got freaked out but dont worry the solution is pretty simple due to the fact we dont have FRP lock anymore
23. Go to download mode and flash UNMODIFIED CP, CSC, AP & BL
24. You will get the no command screen again, no worries though, go to TWRPP websiet and download TWRP for your device
https://twrp.me/
25. Enter download mode and flash the recovery through the AP tab
26. Download this
https://zackptg5.com/downloads/Disab...03.04.2020.zip
27. You will be rebooted to the TWRP screen. And by the way, ALLOW SYSTEM MODIFICATIONS
28. Connect your phone to the PC and transfer the previously downloaded Dm verity file and copy it to your phone
29. Go to Install in your TWRP screen and locate the file and install it
30. Clear Dalvik Cache and reboot
Edit: Alternatively, In the last steps, you can flash turbo luke's twrp instead of official twrp, then select format option in twrp wipe, then flash no-verity-force-encrypt
Then flash magisk from here : https://github.com/topjohnwu/Magisk/releases/tag/v20.4
In all of doing this, don't swipe for system modifications in twrp, it is basically useless and obsolete now, as magisk does everything without modifying system.
Ofcourse, this only applies to stock rooted rom and stock based debloated custom roms (which have non-modified system)
Edit 2: This a copy pasta

Bruh....Did you read that properly. First flash the modified AP, then you will boot then enable OEM Unlock which will disable FRP Lock, then you can flash TWRP. Or just tell me the CSC for your country, I will do all this and send you the modified AP.
Have the same problem with G935FXXS8ETC1

I tried to convert the img,lz4 file with auto tar . No chance. Next time i will try to flash a combination rom.
Perhaps this will solve my oem unlock problem. i can not aktivate it, thats the main problem. I waited 7 Days, but oem unlock ist still not possible.:crying:
I have the same problem. FRP ON, no twrp or custom rom. OEM can not be unlocked to flash twrp.
DId you have success in any way?

I will wait new 7 days, perhaps i have luck. Grrrrrr....... **** Samsung I WANT MY TWRP BACK. With Samsung S5 i had not this trouble.
Cause of this i will not buy any Samsung products neither Tv or anything else. SAMSUNG WANTS TO FORBID THE PEOPLE TO ROOT AND FLASH THEIR PHONES.
Hey, I am over 18.
s7,s8, S9,s10, S20 the people get often problems to root their phones. Will see what happens after 7 days.

yes, that is my problem. I was able to install the modified AP and flashed it how you described it. In developer option i can toggle the button,
cause it went back. This problem stays with the modified AP ROM and also on unmodified stock rom.
There is no green light . It just goes back. MY Status is FRP LOCK on while staying on stock rom or AP modified rom. I have no google frp lock only by Samsung.
Odin picture is only for example what i did (removed you see), i must use my s7 edge to take the picture.
AP FILE was flashed with 3 Files:
recovery.img + (renamed boot.img)+ system.img. + boot.img. converted in one AP FILE
with BL CP SCSHOME in Odin. The phone booted now in system, but in dev.options the oem button can be actived but it struggles back. That´s the fact.

You mean when you enable the toggle, it automatically gets off ??
This is weird indeed, first time seeing this..
Did you bought your phone second hand ? It maybe that its hardware is semi modified ..

Yes, i bought it second hand , but the people did not modiefie the phone. It had stock rom an KNOX 0+0.
The oem toggle did not go back before I installed TWRP and moro Kernel. Do you know if its possible that oem unlock will not go back automically after waiting for 7 days ?

Can't be sure, RMM lock is not implemented on S7 series per my knowledge, but yeah you can try waiting..
Also confirm that your oem unlock toggle automatically turns off when enabled ??

Yes the unlock toggle automatically turns off when enabled . I succsefully flashed AP Rom and also Stock Rom. In both cases the phone boots normally, but there is the problem
with the toggle. Its a pity for the work and lot of tries.
Its the first time im coming across this issue .. don't know then, i tested this solution on many people and it always worked .. you sure your phone isn't a hardware semi-modified snapdragon variant to show itself as a exynos one ? That could make sense why the toggle can't be enabled but still its really weird ..
Sent from my hero2lte using XDA Labs
i have never heared about a semi modified snapdragon. On cpuz or ohter apps it shows me exynos . The last try is too flash the ap file with the meta folder, that i did not tried. Perhaps i mayed a fault while flashing or converting, i dont know. But the phone starts with the modified ap file, but how i said, i was not able to turn oem on.
Next time i will start another try with flashing meta folder in ap file. Perhaps i have luck.
No chance, i installed ap with meta folder. Phone booting in system , oem unlock not possible.

Its the first time im coming across this issue .. don't know then, i tested this solution on many people and it always worked .. you sure your phone isn't a hardware semi-modified snapdragon variant to show itself as a exynos one ? That could make sense why the toggle can't be enabled but still its really weird ..

SM- G935F EXYNOS 8890
After trying a last flash with nand erase and repartion with stock rom binary 8 , the problem still is not solved.
Download mode shows FRP on. Status official.
FRP Lock for hardware is still alive. I normally can sign in to my google account with my device.
The phone boots normally but in dev. options, the oem button automatically goes back. I am not able to solve the problem.
Stock rom works,but no way to flash TWRP cause custom binary blocked by FRP. Its possible to flash different stock roms with binary 8, all is working except s- health.
(notice: phone is rooted, but root has gone). I have no chance to flash a rom below binary 8.
History: I installed TWRP with moro Kernel on Stock rom. All works, after accidentally i disabled the dev. options i got the dead android and i was not able to go back in TWRP
recovery. Twrp had disappeared.
When i start the revovery the "dead android no command" appears and after 1 minute the stock recovery appears.
I read ( Google research) , there was a user who had the same problem with a s7 g930f. He could flash stock roms but no other and he also could not unlock oem in any
rom.
I would be happy to hear from somebody who had a solution. I think there is a new security patch by samsung. Meanwhile i stay on latest stock rom and hope sometime i can unlock oem in dev. options. I have tried all incl. flash with Nand Erase in Odin ( you should not do this, i heard), but nothing worked for me.

[GUIDE] (Exynos) TWRP+Magisk updated guide (June 2021)

Magisk+TWRP for Exynos ONLY
Hi, there are some tutorials out here on the forum but some are outdated, others have dead links and other mix some steps from exynos and snapdragon, so this is a guide on how I did it, My device is the International Exynos LTE Dual sim variant or SM-N985F-DS running android 11 (oneUI 3.1) patch from april 2021 with security patch from may 2021 but this has been tested on many exynos variants.
See DR.Ketan post: https://forum.xda-developers.com/t/guide-how-to-root-n20-ultra-n986b-n9860.4147023/
I based my guide on @dr.ketan 's guide and some bits from the comments and references from that post, so all credit goes to him and the people he reference on his post.
First of all as dr.ketan said:
NOTICE :
Before you move further, make clear that rooting device -
- Your warranty will be void
- Some of functions may not work on rooted device, some function may get back with un rooting, some may never.
- All your data on device will be lost
- Flashing custom binaries may brick (Usually soft but can be hard brick too) your device, so follow it on your own risk!
If you are ready with condition, move further -

1.- BACK UP ALL OF YOUR DATA, copy your files to a PC, make backups on google and samsung clouds and any other cloud service backup you have (whatsapp for example) becuase in this process all data is wiped TWICE.​
2.- Prepare your PC: ​
I personally recommend using a laptop or a pc with an UPS (backup battery) just to be safe.
2.1 Create a folder fo the files and create 2 folders inside named OLD and NEW (this is merely to keep files organized since they CAN be confused (see next steps), unless said otherwise ALL files and folders go in the OLD folder.
2.2 Download ODIN [CHECK FILES BELOW]
2.3 Download YOUR phone stock firmware (you have several options for this, I personally use sammobile but here you have to google on your own. Remember to extract the contents and you should have 5 files.
NOTE(hehe): to get your exact model name you can check on Settings>About phone>Software information>Baseband version.
2.4 Download Magisk APK and ZIP [CHECK FILES BELOW]
2.5 Download Multidisabler ZIP [CHECK FILES BELOW]
2.6 Download TWRP recovery [CHECK FILES BELOW] and place it in the "NEW" folder you created on step 2.1
IMPORTANT: use only THIS recovery from THIS file, since it's modified for exynos and also to skip a step on the process.
3.- Prepare your Phone:​
3.1 Copy the AP file from your PC (the one from the stock firmware) and the magisk.apk file you downloaded, to your phone.
3.2 Install the magisk app (the apk file)
3.3 Open the magisk app and select the first option, there you will have an option to select a file, select the AP file you copied from your pc an tap continue (or start I dont remember)
3.4 Now you will have a "Masgisk_patched-*********.tar" file on your download folder on your phone, copy that file to your PC and place it in the "NEW" folder you created on step 2.1.
4.- Now we start the process of modifying the phone​
4.1 UNLOCK BOOTLOADER: on your phone go to SETTINGS>ABOUT PHONE>SOFTWARE INFORMATION and tap the "Build Number" repeatedly until you see "You are now a developer" (or something similar)
4.2 Go back to SETTINGS and now you will have at the bottom a new menu called "Developer options", enter and toggle on the OEM unlocking option, this will prompt some warnings and an assistant, follow the instructions and when you finish turn off your phone.
4.3 Press and hold the VOL+ and VOL- buttons at the same time and connect the phone to your PC WHILE HOLDING BOTH BUTTONS, this will prompt DOWNLOAD MODE on your phone and you will see 3 options, Press and hold the VOL+ button to unlock the bootloader, now your phone will reboot and wipe all of your data.
4.4 Confirm OEM Unlock is enabled: after the reboot you will get the initial setup process again (as if the phone were new) skip though all (because it will be wiped again) and repeat the process on step 4.1
Now the OEM unlock setting should be GRAYED OUT and with this your phone is ready to be modified
5.- Flashing custom binaries​
5.1 Turn off the phone and put it into DOWNLOAD MODE again (see step 4.3) but this time use the first option, that is, press the VOL+ button ONCE, this will enter DOWNLOAD mode and put the phone in flashing state.
5.2 Open ODIN on your PC as administrator
5.3 On the Options tab UNTICK the "Auto Reboot" option
5.4 Click on the AP button and locate the "Masgisk_patched-*********.tar" on the "NEW" folder.
5.5 Click Start, wait until you see PASS on the top left corner
5.6 Click on the AP button again and locate the "Exynos no vbmeta recovery.tar" file on the "NEW" folder.
5.7 Click Start, wait until you see PASS on the top left corner.
5.8 THIS STEP IS CRITICAL: disconnect your phone from your PC, now READ AHEAD before doing anything.
Here you will have to do a combination of button presses to boot into recovery. Once your phone is disconnected press and hold VOL- and POWER BUTTON (side key) for approximately 7 seconds, once the phone screen goes black immediately release the VOL- button and press the VOL+ button WHILE KEEP PRESSING THE POWER BUTTON. You will see 1 or 2 warning and a glimpse of the samsung logo, keep pressing the buttons until you see the TWRP (Team Win Recovery) splash screen, at this point you can release the buttons.
5.9 now in the recovery navigate to WIPE tab > FORMAT DATA > and type yes to continue (read instructions on screen). DO NOT RESTART. go back to the starting screen and then navigate to REBOOT > REBOOT TO RECOVERY.
5.10 Your phone will reboot into recovery on its own, no need to press any buttons.
5.11 Once inside the Recovery, connect the phone to your PC, after a few seconds the phone will connect normally as if it were in the OS, now copy this files to your phone from your PC:
Magisk.zip
Multidisabler-samsung-3.1.zip
5.12 Go to INSTALL tab on your phone and select the multidisabler zip and install it (it will prompt you to swipe to install), once finished tap on WIPE CACHE/DATA.
5.13 Now do the same with magisk.zip but this time DO NOT tap the "wipe cache/data" button, instead tap on REBOOT.
6.- First Boot​
NOTE: First boot takes a while but if your phone is not showing the initial setup screen in max 15 minutes something went wrong and you will have to flash back to stock firmware and start over.
6.1 Once you boot do the usual initial setup, here you can do it normally and restore your cloud backups.
6.2 When you are all set up, look for the MAGISK app, open it and follow the instructions. Your phone will reboot so make sure you are all set up BEFORE opening the app.
6.3 ALL DONE!​
Hi there,
Thanks for the updated guide!
Maybe worth mentioning that when done, to get back into TWRP power down phone -> connect USB ->press & hold Power AND VOL- until black screen (7sec) -> Quickly press VOL+ with still holding Power button.
Would you know how to update firmware to latest security patches (downloaded from SamMobile for example) now phone is rooted with Magisk, with TWRP recovery and multidisabled?
Regards,
I followed all directions, and Magisk and TWRP are installed. However, I do not have root access. I have an S10e (SM-G970F, Exynos). To get root access, you have to do the bixby, volume up, and power together. I always get to TWRP. When I had only Magisk installed, I always got stock recovery. How do I get the keys correct?
Also, I understand you must have something in the USB port. I tried mostly connected to the computer, sometimes to a charger, and sometimes not at all. Nothing can get Magisk root access unless it boots me to recovery, and then I can just reboot to system (no root) or recovery (same place, still no root).

Only thing I can think of is you are not flashing the correct magisk zip file on TWRP, try downloading it from magisk's official site. Is the same file for the both procedures, you just have to change the file extension accordingly (.apk or .zip)

I tried that file. First, I could not flash with odin 2 recovery.img . I used 7-zip to archive it as .tar, and it still would not flash. I do have an SM-G970F, so it is Exynos. I am not sure of the results, but I did flash with newest twrp-3.5.2_9-5-beyond0lte.img.tar .

After flashing that, it would not boot to recovery but just to download.
Thanks! Worked for me! I have a question:
do you know how to Bypass root detection for bank app?
After I flash Exynos no vbmeta recovery.tar this is the error I get
Couldn't find grp7 symbol in main dtb
failed to permorm fixtps in overlay
ufdt overlay apply fail
UFDT DT Overlay FAIL
need kernel: could not find do normal text
vbmeta: Error verifying vbmeta image
vbmeta VERIFICATION_DISABLE bit is set
CUSTOM VBMETA
VBMETA
I cannot read everything it is so small, so there may be some typos
I found out what I did wrong. I am using SM-G970F (S10e), whereas this forum is for SM-N985F.
Great instructions, though.
Thank you. Just wish I could get root. I cannot because of the updated firmware (August 2021).
Hello, thank you for the guide it worked to root my sm-n986b !

There is just this part that I did differently.
First, to start flashing the twrp at step 5.6 I had to restart the phone in download mode because odin would be stuck at "setup connection" if i tried to flash it just after the file before.
And at step 5.8 I had to keep the phone connected to the PC otherwise it would not boot in recovery menu.
I did all the phone setup and installed "Riru" then "Universal SafetyNet Fix" magisks modules to pass the Safetynet.
I just have one question if someone can tell me if there is a way to not display the bootloader warning message when the phone is booting please.

Thanks, I was just about to post this about the safety net since I just did it yesterday to start using google pay.
I'll add it to the Post as EXTRAS along with some other things.

At my wits end

So I'm trying to get Magisk installed on my bootloader/OEM Unlocked S10+ (SM-G975F beyond2lte) device.
I can do that fine by downloading the latest official firmware for my device, installing that (BL/AP/CP/CSC) through Odin v3.14.
That installs fine.
Then I sideload Magisk v23.0, and the AP file I just flashed via Odin over adb via push.
I install Magisk, recovery-patch the AP file, usd adb to pull the file back over onto my desktop. I restart the phone in download mode and once again populate Odin with the BL/AP/CP/CSC files, but this time the AP file is the one I got from Magisk.
Start that, let Odin restart my phone whilst I'm holding Bixby/Power-Up/Power, I release those three once the bootloader warning message comes up.
I set the phone up like normal, but there's the issue - my 128GB device only reads as having 32GB - I can setup Magisk fine, it asks me to download an extra bit, then auto-restarts the phone after 5 seconds.
Yay, I have root! Boo, I'm missing 96GB of free space...
I've read that installing TWRP can help fix this, fair enough, I try to install TWRP (I've tried through both the "dd" method via adb shell, and patching the twrp 3.5.2_9-3 via Magisk, and installing with vbmeta over Odin), but that then eliminates Magisk.
I've been trying this now for days, literally days, reading through different forum posts, detailing my steps to myself in notepad++ step-by-step so I can see what it is I'm doing.
I'm left with zero clue what to do now except reach out and hope for some help from this forum.
Should have known... Now that I've posted on XDA it's fixed... In-case anybody else is having trouble here are the steps I've written down for myself.
Phone is S10+ SM-G975F (beyond2lte) - Bootloader / OEM Unlock is already unlocked.

A: Try to reboot. If still not booting, consider installing an older TWRP build or a more recent firmware. If you still don't succeed, post here some details about your device and previous firmware and we might be able to help.
Q: Why do i need to format data partition?
A: Because old firmware encrypted your data partition and new rom can't decrypt and use that content / root needs access to data partition to place misc files / phone not booting after flashing root until data partition gets formatted.
Updated first post with official pages from twrp.me, but since the builds are not up yet, i posted latest test builds in post #2.
Regards
well done sir

Can you attach a screenshot of Odin and eventually tell me if you see anything in particular changing on phone screen? It should throw an error or something below the usual download mode lines. A pic of phone screen would be nice but i'd assume it's your only phone..

I installed twrp but it seems that it does not read the internal storage.

And how to flash the multidisabler? it seems that everything is encrypted and is impossible to locate it in twrp?
I found it!
1. enter into TWRP (after flashing twrp.tar and Vbmeta.tar via odin), format data and reboot again in TWRP
2. Being in TWRP, transfer from PC to your phone multidisabler.zip and magisk zip.
3. flash them both
4. reboot system
That is all!

Hello! What can be done to remove encryption from TWRP? I have flashed disabler but it still continues to encrypt. I tried formatting data from twrp, changing file system to EXT4 and back to EXT2 but with no result so far. any help?

I'm still trying to find the issue, for whatever reason multidisabler needs a second flash to work as far as i seen on my device. So for now please flash multidisabler 2 times in a row, until i find a better solution to this.

Thank You very much. It worked!
A big thank you, it works fine.
hey.
i did everything from this guide, and i got root access+twrp installed.
the problem that i am facing, is that i canot install anything from twrp, due to insufficient space.
the system size that twrp is reading is only 8384kb, so every installation of gapps is failed.
i tried to wipe ,format data, and changing the file system, but nothing helped.
please give me an idea how to solve it.
thanks.
Good day
Does this work for Android 13 One UI 5.1?
