A51 AOSP vanilla firmware pure android + root. without gapps. - Samsung Galaxy A51 Guides, News, & Discussion

Draw your attention. There is no bootload patch for the May update (A515F...3BTD4). You cannot build from the May update based on these instructions. But you can create a bootload patch for the May update yourself (we will be grateful if you share it here), or use instructions for self-assembly, firmware that was released before May 2020, or use the ready-made version that is proposed in the topic. May update may be lowered. Accordingly, the instructions are correct.

To install, you must have Thailand stock on your phone. (if you feel the need for pure rom you can install Thailand firmware on your phone (in any country) first and then use this rom)

setting
unlock bootloader
unlock bootloader (step1)
go to settings. about the phone. several times click on the line "build number" - we become a developer.
back to the settings. go to the system item. bottom line is for developers. looking for the line "unlock bootloader" or "factory unlock"
if you suddenly find that there is no “unlock bootloader” item, you need to turn off the Internet, rearrange the date 2 "months ago. Turn on the Internet. Go to the search engine and type something. Then turn off the Internet again, set the correct date and go to the developer's menu.
item appeared
unlock bootloader (step2)
1. turn off the phone.
2. Hold down the volume keys Vol + and Vol -.
3. connect the computer USB to the phone.
4. the phone as soon as it turns on, release the buttons.
5. and immediately hold down the Vol + key.
6. and once again prompts you to hold down the Vol + key
in the same way and blocked.
!!! All your actions will lead to a reset, I advise you to backup and untie your Google, Samsung account !!!
Do not block the bootloader on custom firmware and custom kernels - different devices behave differently, but there can be serious problems, up to and including the brick of the device
put the phone in download mode
odin itself and files for firmware need to be placed in the root of the disk otherwise different kinds of problems may arise.
flash one by one through odin, inserting into the AP window 1) vanilla.tar 2) boot (NoForcedEnforce) .tar, be sure to turn off auto-reboot (auto-reboot, tab in odin)
in case of any incomprehensible situation, as well as between the firmware of the first and second file (if the kernel does not want to flash), go into the recovery and make wipes, then return to the firmware mode DO NOT FORGET TO REMOVE THE CHECK REBOOT IN ODIN after all the firmware boot into the recovery and do everything wipes and dumps!
also with various kinds of glitches can help restart the computer.
ATTENTION! do not disconnect the wire while ODIN is running - wait until ODIN finishes its work and you can disconnect the wire, reboot, etc. without problems as many times as needed.
after installing AOSP to get root, install the terminal (for example, from f-droid https://f-droid.org/ https://f-droid.org/F-Droid.apk)

all health! Have a good mood! happiness!
p.s. IMPORTANT NOTE! start flashing the phone from a working state. that is, when the phone was launched at least once, there is a mark on the unlocked bootloader in the developer's menu. if you start the firmware immediately after resetting to the factory state, it is more likely that you will get an error about a locked bootloader, even if it is unlocked.
if you have a problem and a message is displayed on the phone screen: connect your phone to the Samsung Smart Switch program for recovery, you can try to fix it by flashing the phone through odin with official firmware, you just need to remove the check from the first line of BL, flash everything else as usual AP, SP, CSC ..
also remember, your firmware and kernel file may be damaged along the way. just download again.
p.p.s. The firmware contains 139apk including system (14apk user), at your discretion, disconnect / replace. in a 6/128 phone, firmware takes 8% free 117 gigabytes.
in native stock ~ 500apk%)
p.p.p.s. Before asking questions, look at the topic and header https://forum.xda-developers.com/galaxy-a51/how-to/galaxy-a51-root-unlock-bootloader-flash-t4053065, perhaps this has already been discussed. Thank you.
p.p.p.p.s. The firmware was created for personal use and is not laid out for tests and reviews. use if you need a clean android.

Nice tutorial ! Thanks

I will try this today, thanks!
Can you clarify what's the difference between the first package (AOSP vanilla), and the second one, which is smaller? Are these the same pieces indicated on gabrielfrias 's post?

first link
1) only firmware without zip is just a .tar archive
second link
2) zip archive - A51 AOSP firmware (as in the first link), kernel, original AOSP vanilla, 7z, lz4, otatools, simg2img, odin, all links and descriptions for all these tools. recommendations for battery calibration (forgot to translate - put it in the translator ) links and description to the original Samsung firmware, instructions for unlocking the bootloader (again you need the translator. !corrected! -> posted with the translation in the first post ) in general, everything that was used for creation and result. except for native Samsung firmware since its weight is large
with respect. be happy!

is super.img just renamed from the phhusson AOSP imgs? or is it a modified system image?

Is it possible to install and use samsung pay with this rom?
will knox be tripped?
thanks

Is the NoForcedEnforce boot image necessary for GSIs to boot, or does it only make root available?
I'm trying to boot GSIs on A51 5G (different hardware - just using this thread as a reference). Rooting via Magisk is straightforward, but when it comes to GSIs I get stuck in a boot animation loop. Looking around for some tips.
Ignore, booted AOSP just fine.

I think a rooted system or modded system cannot use any "pay" or banking apps, thus it detect it's a third-party OS and will be prohibit sir

Huawei Honor 4C Index and Troubleshooting Thread

Due to the fact that all guides, rooting threads about the Huawei Honor 4C are scattered all over the XDA and hence are difficult to be searched for when needed, I decided to create an index thread to keep all ROM updates, rooting and unlocking guides in one neat clean thread.
I’ll try my best to keep this thread updated as soon as new information is released from trusted sources or whenever new mods, ROMs, etc. are released.
You can also post your queries here and I'll try my level best to answer them.

Upgrading from Kitkat to Lollipop
Always try to take OTA updates whenever possible as user data isn't wiped. However, if you want to start anew, just use the below listed methods. ​Backup all important data on internal storage before performing upgrade. Internal Storage will be completely wiped after upgrade. Ensure battery is fully charged or at least 30%. Do not press any button nor attach your phone to charger after the upgrade process is initiated.​Normal Upgrade (Upgrade using the Software Updater)
Download the Lollipop Stock ROM according to your region. See Stock and Custom ROMs > Download Links section for download links.
Ensure your SD card has atleast 3.0 GB of free space.
Extract the downloaded *.zip or *.rar and copy the dload folder (with the UPDATE.APP in it) to the root of your SD card. (In some update packages, there might be multiple UPDATE.APP. Hence copy the UPDATE.APP with has the largest file size)
Insert the SD card (if not already) and navigate to Settings > Update > Menu > Local Update > Full Package:UPDATE.APP . Now finally press Install.
Your phone will reboot to recovery. Wait for the progress bar to finish. When it does you phone will switch off. Hold the power button to switch it back on.
First boot might take some time due to app optimization hence be patient.
Forced Upgrade
Download the Lollipop Stock ROM according to your region. See above section for download links.
Ensure your SD card has atleast 3.0 GB of free space.
Extract the downloaded *.zip or *.rar and copy the dload folder (with the UPDATE.APP in it) to the root of your SD card. (In some update packages, there might be multiple UPDATE.APP. Hence copy the UPDATE.APP with has the largest file size)
Insert the SD card (if not already) and Power Off your device.
Now while holding Volume Up and Volume Down buttons, hold the Power button to power on the device and boot straight to Software Upgrade Mode.
Wait for the process bar to finish. Device will automatically reboot after the upgrade has completed successfully.
First boot might take some time due to app optimization.
Downgrading from Lollipop to Kitkat
Method 1
Download your current Lollipop ROM (see the first section for download links) and the Kitkat ROM you want to downgrade to.
From Lollipop Stock ROM: First copy UPDATE.APP located in 0_CUSTOM_PACKAGE\MiddlePackage\dload to dload directory in the root of your SD card.
Use any of the method posted in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to flash the Middle Package UPDATE.APP. Skip the copying stuff in those sections.
After the flash has completed, delete the existing UPDATE.APP.
From Kitkat Stock ROM: Copy the Main UPDATE.APP (one with the larger size) to the dload directory in the root of your SD card..
Use any of the method posted in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to flash the Main Kitkat UPDATE.APP. Skip the copying stuff in those sections.
Method 2
This method requires ROOT SU privileges on your device. Also please make a backup before proceeding.​
Make a TWRP or CWM backup. If something goes wrong, you must have something to restore from.
Download and install Terminal Emulator from Play Store. Open the app and execute the following commands (grant SU privileges when prompted):
Code:
su
mount -o rw,remount /system
Open your favorite File Manager which supports browsing / partition and obviously Root permissions , and navigate to /system.
Search for build.prop and open it.
Find ro.product.model and change it's value to balong.
Save the file and make sure permissions are set to -rw-r--r--.
Reboot you device, flash Stock Recovery and any Kitkat ROM you want. See Unlocking Bootloader, Rooting and Custom Recoveries > Restore Stock Recovery for flashing Stock Recovery instructions and Stock and Custom ROM > Upgrading from Kitkat to Lollipop for Stock ROM flashing methods and instructions (You have to use the FORCED METHOD to flash).
Flashing Stock ROM in cases of bootloop or otherwise
If you are stuck in a bootloop, device keeps on restarting follow this guide.
Before you follow this guide, perform a FACTORY RESET on your device. If this doesn't work, then continue.
Download the ROM version currently on your device or any newer one. See Stock and Custom ROM > Download Link section for download links.
Ensure that you are on Stock Recovery. If not see Unlocking Bootloader, Rooting and Custom Recovery > Flashing Stock Reovery section to flash Stock Recovery.
Use the Forced Upgrade method in Stock and Custom ROM > Upgrading from Kitkat to Lollipop section to re-flash the Stock ROM.
Flashing Stock ROM when device unable to boot to recovery or update mode
Alright! So your phone is completely messed up and you can't boot to recovery or anything. Well this guide is for you! Resurrect that device!​Always use original data cable that came with your device for flashing stuff. It is not necessary but recommended.​Installing ADB / Fastboot and Necessary Drivers
Download 15 Seconds ADB and Fastboot Drivers. Visit the official XDA forum for download and installation instructions.
Install Fastboot drivers by downloading and installing Huawei HiSuite via this link.
Flashing the ROM through Fastboot
First download and install Huawei Update Extractor. Visit the official XDA Forum for download, installation instructions and usage.
Extract boot.img, recovery.img and system.img from UPDATE.APP and copy it to any directory on your computer. See Miscellaneous Guides > Extracting Update.APP section for instructions.
Open Command Prompt in the directory where you have extracted the files by holding Shift and Right Mouse Button and finally click Open Command Prompt window here in the context menu.
Completely power off your device.
While holding Volume Down button, connect your device to PC via USB cable to boot to Fastboot Mode.
Execute these commands one at a time using the command prompt.
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot erase cache
fastboot erase userdata
fastboot reboot
Now hold Volume Up button and Power button simultaneously. As soon as you see the Honor logo, release the power button. Your device will now boot into recovery.
Perform a Factory Reset through recovery.
Availability of Stock based Custom ROMs and AOSP based Custom ROMs
Unfortunately, light is pretty dim here. There are no Custom ROMs available for this device. However KangVIP Custom Stock Based ROM is available for the Chinese Variants but I couldn't get the links because they want you to register first. Also, because Huawei hasn't published the chipset source code, so no CM or AOSP based ROM has been developed for this device.

ROM Addons and Miscellaneous Guides​Xposed Framework on EMUI 3.0 and EMUI 3.1
On Kitkat EMUI 3.0, Xposed works only when Use System Hooks is disabled in Xposed Settings. This means that modules such as Gravity Box, Minminguard won't work! However, modules that don't modify the UI work without problems.
On Lollipop EMUI 3.1, Xposed works flawlessly and great! See my thread here for instructions and details: http://forum.xda-developers.com/android/general/guide-workaround-running-xposed-t3338765
Viper4Android Sound Mod
Unfortunately, Viper4Android is a no go on EMUI 3.0 and EMUI 3.1. There is partial support i.e. the mod will only work when it is running in background and will not work on stock EMUI apps such as Music. Also be sure that after installing, DTS Sound Engine will be disabled (or won't work in most cases)!
L Speed Mod for Android Lollipop EMUI 3.1
This mod works flawlessly and I'm loving it! Visit the XDA thread for all information.
Changing Region
This is some really risky stuff. If anything goes wrong you'll end up with a bricked device. I have personally tested this and have successfully changed my region from Pakistan to Malaysia. Nothing will go wrong if you carefully follow the instructions!​Prerequisites
Your device must be rooted.
ES File Explorer installed (no other Root Explorer should be used).
Backup of your stock ROM.
OEM Info File Download Link
Instructions
Dial *#*#2846579#*#* from your device to pop up Engineering Menu. Go to Network Information > Country / Vendor Info. I have listed some of the vendors below:
1. hw/spcseas – Malaysia
2. unicomelectric/cn – China
3. hw/meafnaf – Pakistan
4. mts/by – Belarus
Open ES File Explorer, switch to Root Mode and navigate to /data/. Open custom.bin using ES Note Editor. Clear the Vendor Information text in it and enter the text corresponding to the region you want to switch to. In my case as I switched from Pakistan to Malaysia, I cleared hw/meafnaf and inserted hw/spcseas. Save the file and make sure it's permissions are set to rw-rw-rw
Extract the OEM File Info and copy the oeminfo file of the country you are switching to. Using ES File Explorer, navigate to /dev/block/platform/hi_mci.0/by-name/ and paste it there. Replace the file currently present. Don't delete it! Now set it's permissions to rwx-rwx-rwx.
Finally reboot your device and enter Engineering Mode to verify Country/Vendor.
Download the latest ROM of the Vendor you switched to and flash it using Forced Flash Method. See Stock and Custom ROM > Upgrading from Kitkat to Lollipop for details.
Extracting Update.APP
This is a simple and straightforward guide! Follow and follow...​
We'll start by downloading Huawei Update Extractor. Visit the XDA thread and scroll down for links.
Extract the downloaded file in a safe folder and launch HuaweiUpdateExtracter.exe
Make sure Profile is set to Unknown (worstenbrood).
Switch to Extract tab and locate the Update.APP. (Well you must have downloaded the Stock ROM. No! No problem! See Stock and Custom ROM > Download Links section for links).
Hold down Ctrl Button and select the partitions (such as System, Recovery, Boot, etc.) you wish to extract. Then right click on any one of the selections and click Extract Selected.
Browse for a location where you wish to extract the partitions (or images).
Tada! It's done!

The problem is, Germany is not on the country list during sign up.. So you can't create a phone account using a Germany phone. Huawei has made it an obligation to use a phone account for unlocking.

Alright... Then try this method (it does the same thing as region change does). You must be ROOTED.
1. Open build.prop located in /system/.
2. Change ro.product.model value to Balong.
3. Restart your device.
4. Now flash away any Kitkat ROM of any region.

No manufacturer wants the end user to downgrade to a lower version. You have to be rooted and bootloader unlocked in the first place to downgrade. The middle package is in B330 Lollipop ROM. You may try flashing it but I doubt it will work on B360.

No, you don't need to be rooted. Also this is completely safe. Huawei Recovery won't flash the file it is not compatible so feel completely safe to try it!
I was on B330 Lollipop ROM and I did downgraded mine to Kitkat just for Xposed!
im using b360 lollipop. now i will try to flash the middle package of b330 to downgrade mine to kitkat. im hoping it will work.
@mfbcool If you're challenging my info , Our Phone Support 4G LTE Network!! one thing and 2nd thing, we have Sources for chipset of Our devices but thats are for Arm only not Arm64, so they are less used for us,,, we only need a developer,,, and third and last one, we can never change region as mentioned above and in carbontesla.com, i already read it, but thats not the way!! we needed vendor files which are available only for Pakistani one Rom (B120) and Indian (B390) only,,, not present for chinese or any other region,,, so we cant change region!!

@ijameslargo you dont need to be rooted and unlocked bootloader for downgrading, you can downgrade to any version from any Rom,,, if you have done in any way then its ok, if not then tell me, i will guide you!!

My turn!
1. So my desktop computer supports WiFi cards but it hasn't one installed so it neither can't search Hotspot networks nor can't create one. Same case here! The Kirin 620 SoC has SUPPORT for 4G networks but the radio module required to make it available is not installed ON THE HARDWARE on our 4C (it's installed on P8 lite though) or IS DISABLED ON THE HARDWARE SIDE.
2. There are more things required to build Custom ROM other than kernel sources (which you are of course mentioning about). You need open source drivers for CPU Management, GPU, WiFi, Bluetooth, Dual SIM card, Graphics Stack, Radio Bands support, NFC, etc. Unfortunately, those aren't included or open-sourced in the source. That's why the only custom ROM ever made for Kirin SoC, the Cyannogen Mod 11 for Honor 6 has no support for Bluetooth, NFC, USSD Execution, etc. The developer for that ROM made seriously tons of patches and spent countless weeks to make it happen. That's also the reason why there is no CM (or any AOSP) ROM for even high end Huawei devices such as Mate 7, etc. These devices however do have KangVIP ROM which is Stock Based Chinese mockoff.
3. I did changed my region from Pakistan to Malaysia successfully. If that didn't worked for you, I'll upload flashable zips probably in few days that will automatically change the region for you
I wish you ever had a Motorola phone which will hard brick on downgrade (yup a dead phone RIP). Unfortunately no manufacturer wants the end user to downgrade because of security patches, exploits, etc. You can always try flashing system.img of a lower version together with boot and recovery to see whether your phone has downgraded.
That 'balong' method I posted is actually an exploit or more preferably a cheat. The phone loses it's identity, model and version and thus any version either higher or lower can be flashed. However it does require root.

Great great!! You should know one thing too.... You didnot mention CM12.1 of 4X ?? You know, thats made from our Kernel Sources!! Nd dev made all drivers etc for it.... So just sources enough for it...right...
And i once also changed region to malysia/india, but it got balong build,,, then i flashed vendor file of specified rom,,, it changes to its real build!! Then my region was really changed!! And about 4G,,, our hardware support 4G but software didnot!! See in indian Rom, 3 options 2G,3G,4G available in preferred mode!!

Oreo 8.1 Update T585XXU4CRJ8 problems

Hello all
I installed the latest T585XXU4CRJ8 Oreo 8.1 update over Nougat 7 on the SM-T585. (BTU / UK)
Everything went well using Odin and the Oreo stock rom from the Updato website.
Cleared the cache and factory reset from recovery mode as normal practice. Booted up ok.
The problem is the device doesn't recognise the network sim card anymore (worked perfectly on Marshmallow & Nougat).
I've tried factory reset a few times, no difference.
Removed and reinserted the sim, even tried another sim.
Having checked 'about tablet > software details' , carrier is unknown and the IMEI has dissapeared !
I've tried to reinstall Nougat 7 and Marshmallow 6 back on the SM-T585 and Odin fails every time.
Tried 2 computers and 3 different usb cables.
Even trying to reinstall Oreo 8.1 again Odin fails!
Theres no frp lock activated, and the oem unlock tab is checked, usb debugging enabled too.
I've read somewhere Samsung have done something to Oreos BootLoader file to stop people downgrading back to earlier software.
I know its early days, but if anyone can offer any solutions, it'd be appreciated.:good:
How to change the BL file version, so i can reinstall earlier stock roms back?
The Oreo update seems more hassle than its worth and I didnt expect the sim card to be unrecognised once updated, let alone being faced with the puzzle of how to downgrade the software.
Thanks for reading. :good:
I think the problem was I used all four files (AP, BL,CP & CSC) from the Netherlands rom and that's whats screwed the device up!
As in no SIM card acknowledgement. I ran the IMEI number off the rear casing through a blacklist checking site and it came back clean.
After many attempts trying every Odin program variant possible and even tried mixing and matching files from different stock roms ( MM 6.0.1 , N7 and Oreo 8.1). To try and get the network carrier file installed, Odin refused to install anything.

https://download.chainfire.eu/1069/CF-Root/CF-Auto-Root/CF-Auto-Root-gtaxllte-gtaxlltexx-smt585.zip
https://twrp.me/samsung/samsunggalaxytaba101wifi2016.html
Tried the above routes to root to no avail, but Magisk worked by patching the boot.img file (which worked ok). Then tried Odin to install TWRP recovery, again from the site above, nothing but blue and fuzzy lines on the boot screen. The device wouldn't boot into the OS, had to go straight to download mode. Prior to that, I even installed the TWRP manager apk and connected to wifi to flash the TWRP.img from inside the OS environment and the same happened again with all variants of TWRP! Wouldn't boot, properly, no screen visuals, but lines......
Surely someone else on here has the same device (BTU UK) SM T585 that has a working TWRP recovery?
After many hours, I couldn't get Odin to play ball , so the only option left was to try the route of root, twrp recovery then installing a custom rom from twrp.
(https://forum.xda-developers.com/ga...-ultra-lean-rom-galaxy-tab-10-1-2016-t3467942)
But it's a no go as TWRP wouldn't install properly, I'm totally miffed by the damage the software has done.
Surely just reflashing the CP file should have reinstated the network facility, but it hasn't.
The last resort is for me to wait until Samsung actually release the UK version of Oreo 8.1 and see if I can get the sim card working again.
Moral of the story is wait until a UK version of the update is released, and even then you have to question is it worth it, if Samsung are making bootloader files so no downgrades are possible, nor allowing any modifications.
Hopefully this info may help others out who are thinking of upgrading or having similar issues.
Cheers for reading

I had the same problem, went from Lineage 14.1 to Oreo stock rom (the flashable one you can find on this site, i flashed also the Bootloader/modem file in the thread). No imei, no baseband. Returned back to lineage and got back imei and baseband, but after my screen was going to sleep (after the regular 1 min) I had only black screen and vertical red lines. I flashed then Resurrection Remix 6.2, Lineage 15, Lineage 16, always the same problem. Then I used Odin and the original firmware of Nougat from SamMobile, at the first attempt i flashed only the AP file. I turned to have the same problem, but this time the lines were white. I flashed all the 4 files again with Odin, problem solved and back to Lineage 14.1 (the only custom rom were everything works)
Domenico F.
What version of TWRP have you installed for the T585 and from what site?
Also what root method did you use?
I have tried all available and all seem corrupt i.e don't install properly, no proper boot up with onscreen options. Just fuzzy lines.
Again root i've tried many, but don't work with this Oreo 8.1., even Magisk is problematic.
I think its pretty sad of Samsung sending out poor quality updates for us to use. Their heading the same way as Apple and the way they control customers.
If I could go back to a custom MM or Nougat, I would. But TWRP / ROOT are an issue. i.e no TWRP no custom rom!
If anyones thinking of updating and reading this topic, stay clear of the Oreo 8.1 update for the SM T585. Once installed theres no turning back.....so it seems
Thanks for replying.

just flash the nougat firmware from SamMobile. You have to flash all the 4 files in the zip you are going to download. AP, CSC, etc. Once you have your tablet completely stock you can install again TWRP and flash whatever CUSTOM rom you want.
I easily rooted the phone with odin flashing only the TWRP in AP box (twrp taken from this post https://forum.xda-developers.com/showpost.php?p=78145080&postcount=160) avoid the auto-reboot. You have to put the tab in DL mode, connect it to pc, start odin flash the twrp in AP file e unselect Auto-reboot. As soon as the process is done you have to log in recovery mode at the first boot with home + power + vol up and flash dm-verity. I rooted with Magisk without any problem just flashing the v17.3. Now i' m back to nougat (from Oreo) and i can install whatever custom rom i want. But honestly the only one fully working is Lineage 14.1. Resurrection remix 6.2 has problem with camera and gps don't lock. Same for Oreo version. Tried Pie, same problem.
Domenico F
Thanks for the info.
I tried to install MM 6.01 & Nougat 7 stock rom and they wouldn't install, no matter what I did. ( see Odin pictures )
The last chance was to try Oreo 8.1 again and I did manage to reflash the 'Netherlands stock Oreo 8.1 rom' (after 10 hours!) using all four files (AP,BL,CP,CSC).
I then reset the device a couple of times via stock recovery. Took the OEM lock off, theres no FRP lock either. Enabled developer mode > debug mode (all the usual setting changes prior to rooting / twrp install).
At this point the imei and sim card network ARE recognised and work on the device as normal.
HOWEVER I found once I rooted by any genuine means > Magisk v16 (patched boot img taken from stock rom) and also the CF gtaxlltex sm t585 auto root method.
And when the device booted back up, the 'imei and sim card' WERE NOT usable, nor recognised, no network...........I also noticed BusyBox wouldn't install at all, message about integrity of root.
Adaway and Lucky Patcher recognised root.
I also then tried installing TWRP 3.0.2.0 -3.2.3.0 from many locations and again, none of them worked at all. Just blue lines, fuzzy screen etc. On some occasions Odin wouldn't even process the files.
I include pictures of the files I used.
Its evident to me that I can use the device normally i.e sim card , make calls, data etc if I don't attempt to install root / twrp recovery.
So no root , no twrp , then no custom rom usable or installable. It sounds like Samsung are out to stop custom software on their products.
If the Netherlands stock rom 'BL' (boot loader) file is encrypted with this new binary v3 or v4 to stop OS modifications. I wouldn't recommend using it when flashing the new Oreo 8.1 rom or future new releases.
The best way is to just use the AP file ONLY and overlap Nougat 7 or MM 6. And because you've kept your original BL from earlier stock roms, it may be possible to downgrade back to MM or Nougat if need be.
Once the latest new Oreo / Pie 'BL files' are used in the Odin flashing process, it causes big problems.
Hopefully, maybe someone smart enough can find away to decipher these new BL files and offer a replacement method. which will allow software downgrades and modifications

Honestly i think this run for Oreo it's not really worth. I said you what I did and now i have no problems. I'm not in hurry to use Oreo (as stock rom). I think Lineage 14.1 is the most stable and fastest rom i tried till now, and most of all everything is working. I think i'll give a try via Odin to the official stock rom when it will be available for download (i live in Germany) but sadly I don't use most of the Samsung bloatware installed by default.
WRP Oreo 8.1 on Galaxy Tab 10.1 (T585)
Then I've tried
twrp_3.2.3-1_sm-t585_29918 which gives only stripes when booting into recovery
Do I have to flash the stock boot/recovery before flashing this one,
or this is broken, as well.
Many thanks for a hint,

Hope this helps.
So, as I was trying to search for my Galaxy Tab A6 (SM-T585) for Deodexed Stock ROM, I stumbled upon this thread https://forum.xda-developers.com/galaxy-tab-a/themes/mod-twrp-odin-t3650215 just follow the instructions to fully flash Oreo. By the way when flashing Root, I would recommend Magisk Beta https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
it does not damage the IMEI at all(Thread here, read the comment:https: //forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) . The TWRP, I think we should leave it be, don't flash an update for the TWRP.
Thanks. Hope this helps.

Neither does a custom recovery, so not sure what your point is?
I mean if your having problems using MAGISK use the beta version

(Method) For everyone who wants to Downgrade Galaxy S8 to Oreo/Nougat

Hey guys!
I recently read many Questions About downgrading the Galaxy S8 to 7.0/8.0 after we got the 5x Bootloader.
Well many of you say NO but What many of you forgot is that there is a way to Downgrade your phone.
I already had that Problem with my S6 back in 2016, where I wanted to Downgrade it to 5.1. All you Need for a Downgrade is a Combination File.
Combination files are basically used for testing purposes in the Samsung devices. These files are there to make sure that the functionality of your device is error-free, before making its final release. These files are created by Samsung company and are found in only their devices.
Combination ROM Advantages:
Its help you to repair imie number in some models like S8/S8 plus S7/S7 Edge S6/S6 Edge…
Its very useful in bypass samsung account in too many models.
Its very useful in bypass Google account in too many models.
Its very useful for downgrade in some models.
Its help you to enable usb debugging.
its help to remove any security FRP / Reactivation Lock from Samsung like 2016-2019
You can find Combination Files for Galaxy S8 devices here:
G950U with latest Bootloader: http://www.mediafire.com/file/j8xi2n73zhh37q1/COMBINATION_FA70_G950USQU5ARG4.zip
G950F (currently only for 4x Bootloader): http://www.mediafire.com/file/c37zq...QB19841686_REV00_user_mid_noship.tar.rar/file
Here is a Video of Downgrading a Galaxy S6 Edge with Combination File : https://www.youtube.com/watch?v=dOKJcHU1pXM Should work with S8 too
Hello, nice tutorial!
Want to ask:
"Combination files are basically used for testing purposes in the Samsung devices. These files are there to make sure that the functionality of your device is error-free, before making its final release. These files are created by Samsung company and are found in only their devices. "
So only Samsung releases these files to public? or are leaked?
I`m asking to check if I should wait or not, I had V4 bootloader but recently by accident with the latest update I got V5

I would recommend you to wait till the latest Combination File gets public for the G950F/G955F. They do work very good and are also stable. Usually I think Samsung does not public These files online but they get leaked very often. I used the Combination File to Downgrade my S6 from 7.0 with Bootloader 6 to 5.1.1 with Bootloader 2.
Im sorry but I can only explain the function of a Combination Rom along with the Galaxy S6..
Once Cthe latest Combination File is available, do this:
1. Download your Nougat/Oreo Firmware you want to install
2. Download Combination File with the latest Bootloader Version
3. Downlad 7zip, since you Need to edit the firmware you want to install
3b) Extract the firmware you want to install to a new Folder
3c) Delete all files except for boot.img, cache.img, recovery.img and system.img
3d) Open 7zip from your Start Menu and locate the firmware Folder
3e) Mark the remaining files and press the green "Add" Button at the upper left corner and create a tar (Odin Flashable) file
4)Download Odin
5) First uncheck Auto-Reboot
6) Now first Flash the Combination File
7) Afterwards go directly again in Download Mode and Flash the tar- firmware File
8) Reboot your phone and do a wipe
9) Congrats! You now have Stock 7.0/8.0 Back!
Notes: Fingerprintscanner wont work, because it is a part of cm.bin, OTA Updates wont work as well, Dont worry if you see a green text next to the Phone logo while starting it. Thats normal and not an error.
Backup your files before you do that!
I hope it helped you

Yes, many thanks for response!
I guess I will wait until I get the combination of files, but until then I want to switch CSC, found a solution to use THAI sim card, but not sure, if everything goes ok, I guess the new OTA update will be the latest from THAI, there are no changes to get bricked by this method right? ( I will be able to get back to the ROM stock that I have now? )

Hi, ok but it means that i cannot use fingerprint or ota update anymore or after dowgrade could i install full stock firmware with odin and recovery functionalities?
Will this trip Knox?
Any idea if I can downgrade from pie on a S8+ on bootloader 6?
I've tried this method on my S7 edge but I've stucked on step - deleting files.
After extracting the firmware I get 5 files- Ap, Bl ect.
When i extract the AP file (previously deleting "md5" from the name, and becoming rar file) there are only 3 new files (nothing for delete if i remembering correctly)
Files i need to delete are on other files from extracted firmware.
At the end I finished on unsuccessful flash.
I want to go back to nougat on my S8+ (955f), but i dont want to take risks, so I did flashing on old device with corect firmware.
I'm really mad at Samsung. Battery life become horrible at pie. Thats why I want to go back to nougat or at least oreo.
I will post some videos after day or two how is possible to downgrade android version on some Samsung devices with higher bootloader version. These methods didn't worked for me but may be they will encourage some of you to make possible the downgrade.
As I promised:
1. Interesting way to downgrade Samsung Device (J series) when touchscreen does not working:
https://www.youtube.com/watch?v=SmfgxoUhflA&feature=emb_title
2. Second method:
https://www.youtube.com/watch?v=ZKg1DC4ul_g&feature=emb_title
As I remember oreo and nougat have pro mode on video recording and faster charging speed. I hope someone to explain is it possible to downgrade S8 and whats are the steps with this method.
so if i want to downgrade to firmware with bootloader v4 but my phone has now v6, will i download combination file with bootloader 6 or 4? I didn't get that part, sorry. i have s8+
edit: ok, 4 didn't work, so i guess need to get 6
Does anyone know the password for the linked Combination file?
Thanks for this thread.
I want to downgrade from Oreo to nougat too, I'm on "U1" security patch, but I don't understand the order of bootloader version... Can you try to explained how to ?
I found this if it can help : https://combinationfirmware.com/combination-samsung-galaxy-s8/

Since you are on bootloader version 1, you don't need the combination files. If you were past version 2 they would be needed.
Once you update to a new bootloader you can't go back to software on the older bootloader without the combination files.

If you have an Exynos version, maybe ask around on that thread.
If you have a Snapdragon variant, you can't flash that ROM.

It means phone is not OEM unlocked flash older firmware and check. It's been long i rooted this phone, currently not using it I don't remember exactly what I did to get rid of this msg - unofficial binary.
But i remember changing date back to few months and enabling allow OEM unlock.
There is another guide of rooting including a tool phoenix something. Search Xda it exits here. All I can say is keep fighting i tried a lot time and at the end it worked, I even used custom kernel Helios and rooted properly with magisk.

TWRP, Rooting and Custom Rom HELP SM-T510 Tablet Tab A 10.1

Hey guys, this is my first post. I just bought a Samsung SM-T510 and would like to unlock all the features. I'm currently trying to follow multiple guides on how to do so. To my understanding, my best bet is lineageOs 16. I've been following https://forum.xda-developers.com/gal...-16-0-t3987317 alongside with https://forum.xda-developers.com/gal...howto-t3989361 and I'm pretty confused on the method order i need to follow. What I mean is do I install rom first, TWRP, Magisk etc.?
More guides ive been following:
https://forum.xda-developers.com/gal...-10-1-t3934805
https://forum.xda-developers.com/app...mless-t3473445
https://topjohnwu.github.io/Magisk/i...system-as-root
I see posts saying I need and don't need Multidisabler so I'm confused on what I actually need: https://forum.xda-developers.com/gal...ption-t3963020
Another one: https://forum.xda-developers.com/gal...ption-t3919714
https://forum.xda-developers.com/gal...eries-t3918699
I have so many tabs open currently; I know I'm missing a few important ones.
So given all that info, i think i have all the software to do this between kernels, rom, twrp, odin, magisk, multi disabler? and i think thats all.
My sm-t510 build number is T510XXU2ASK5, looking through the lineage rom guide, I click the link https://samfrew.com/model/SM-T510/ and i see different versions. I'm honestly completely confused about this file and how I'm going to use it. I understand it to be the stock rom? as in factory software? With TWRP too, the numbers don't match my current build number leaving me very confused.
Do I need to downgrade my build number (i don't know if it's even a thing just asking)?
I think i can do everything relatively easy once I have an understanding of what to do first (order of things) and the specific files for the specific steps. When I'm reading these guides, I honestly have no idea which download goes for what. For ex. going back to https://forum.xda-developers.com/gal...-16-0-t3987317 like what do I need to download, the build number listed in notes regarding kernel or go to the download section right below and use that? Or both and if both, how do I use them separately for there a specific purpose? I cannot find anything that makes me feel comfortable rooting/custom rom on my device. Not comfortable in terms of I don't know what I'm doing exactly. I have put days of reading into this and still, I cannot figure out how to do this. I would really appreciate it if someone could help me. This is stressing me out and I would like to get this done before Monday due to me having some serious surgery. The reason being; I won't be as fresh on everything I've read recently.
I'm sorry if this post is choppy and all over the place. I'm just exhausted and clueless at this point. If I left any info out in order for someone to help me please let me know so I can provide it.
EDIT: The TWRP file ends in build number SK1, the file lineage-16.0-20191019-UNOFFICIAL-T510XXU2ASI4.tar.md5 doesn't match the TWRP file as well as my current build number; which ends in SK5. So nothing is matching the 3 last characters in my build number across all guides besides the samfrew link.
Also, I keep seeing i need a .tar TWRP file for recovery (?) but when I unzip both files are .img (named boot/recovery)
You don’t unzip the .tar files. Keep them as is.

I don't get a .tar file until I unzip the folder; I get a filed with .tar.md5
My recommendation would be to first upgrade to T510XXS2ASK1 of the OEM firmware, since that's the latest version for which Samsung has published kernel source. Use the latest release of Odin and install BL, AP and HOME_CSC. After this, unlock the bootloader and prevent VaultKeeper from relocking it by always enabling Debugger Options while connected to the Internet after a factory wipe.
From there, you could just install TWRP, install the latest MultiDisabler, and live with the Samsung firmware. You could even install Magisk to root. However, I prefer a clean Google OS without all the OEM bloatware, so I'd recommend installing the latest Nexus Stock (which includes TWRP and the custom kernel that disables Knox boot security features). Again, use Odin and install it to AP and do a factory wipe in TWRP because file-based encryption is still unsupported on these custom ROMs.
You could install LineageOS instead, but I haven't yet updated that for T510XXS2ASK1. I've just been busy and Andy hasn't been releasing any new LineageOS 16 GSIs. We're also pretty close to releasing a LineageOS 17 build.

Just rename the file cutting off the .md5.
is it possible to downgrade from sk5 to sk1? you cannot upgrade to a later version, and I know downgrading can have reverse effects on the tablet. I have same tablet I would like to know. if I flash sk1 is there a way to fix it if it bricks?

We must RAMDISK YES in Magisk but to do that we need to extract recovery.img (https://www.droidwin.com/install-magisk-in-recovery-root-android/) from stock original ROM T510OXM5CUJ1 and Im stucked at the part NORAMDISK trying to patch recovery.img with Magisk Manager (with recovery mode checked) but i only get the "waiting for device in ADB" and I conect disconect USB C and nothing...Still NO RAMDISK...
I used 3 different ROMS but no lucky and tried with firmware CUJ1 but no lucky again. Without "NORAMDISK: YES" no root...stucked. But i saw a T510 with OrangeFOX!

I just finished flashing the latest Nexus ROM and rooted it with Magisk merely by flashing the Magisk zip file. You can flash the Nexus ROM without first flashing anything else but the latest CUL1 (not CUJ1) stock ROM. Nexus includes both TWRP and gapps. The only time you have to patch things to get Magisk installed is when you are trying to root a stock ROM instead of a custom ROM. Custom ROMs always to the patching for you.

Wow i will try this today and will post feedback. Are you on Android 11? Thank You!
UPDATE: So...flashed with T510XXU5CUL1...
From OEM stock firmware:
Unlock bootloader -> done
Hold Vol Up & Vol Down buttons during restart to enter Download mode
Install TWRP to AP with Odin --> twrp-3.6.0_11-2-T510XXU5CUL1-20220218.tar ---> this put the tablet into emergency mode... had to do again "Hold Vol Up & Vol Down buttons during restart to enter Download mode" and reflash it again. stucked at this point. cant flash TWRP with that! Maybe this TWRP file its for Android 11.2 and im on 11?

You don't need to flash TWRP if you flash https://forum.xda-developers.com/t/...k-for-2019-galaxy-tab-a-10-1-sm-t510.4234889/ TWRP is built into this ROM. After installing stock CUL1, did you boot it, connect to wifi, skip the rest of setup and then enable Dev mode before rebooting to download and flashing from Odin?
edit: Don't attempt to download from the regular download link. Use the link under Build archives that says Android File Host and scroll down till you find the CUL1 md5 file.

AH! So donwloaded Nexus_Stock_CR_T510XXU5CUL1-20220219.tar and put into AP in Odin... and FAIL. Error: "Only official released binaries are allowed". Before i flashed with T510XXU5CUL1 didnt conect wifi and enabled usb debug.
EDIT: i dont have OEM unlock option in DEV but its unlocked, i checked when in downloaded mode it says "lock device and..." so its unlocked.

You must connect wifi and enable Dev mode before flashing. If, after flashing CUL1, you went through the regular setup routine and put in a Google Account, you must also enable OEM in Dev options.

USB cables are notorious for being flaky. Sometimes it helps to just turn the cable over and plug it back in. I always keep several on hand so that if I have connection problems I can try another cable.
