Is it possible downgrade SM-T520? - Galaxy Tab Pro 12.2, 10.1, 8.4 General

I'd mistakenly downloaded and flashed "T520UEUAOD1_T520XARAOD1_HOME.tar.md5" which is Chinese and no Google apps or anything, then I tried falshing "T520UEUAOD1_T520XARAOD1_HOME.tar" which is US I assume, but I fail at system.img everytime on Odin, is there a way I can flash it? Because without it, I can't even install LineageOS into this Tab as system framework force closing at boot along Google services Any help is appreciated

Copy paste error? Md5 is a hashing algorithm, which can be used to verify the integrity of another file. I think you have the US file.
Make sure you have factory reset, and that you are not installing gapps over a stock ROM.

Need help with my G360F.

Hey there,
So I have twrp installed and tried to flash xposed such resulted in a bootloop, tried to install a stock ROM giving me an error, after that I accidentally deleted my system folder when trying too wipe data. I do not have a PC at my disposal, any ideas on what to do? Tried again installing a stock ROM but it gives me an error. I can give more information if needed.
The file seems to be a tar.md5 file but again I do not have Odin at my disposal.
Can someone please help? I really need the phone working.
Edit: if someone else add a backup of the system files would I be able to flash it?
If you can open TWRP, I suggest you to flash the Xposed uninstaller : https://forum.xda-developers.com/showthread.php?t=3034811
I had the same, my device stay on "Samsung Galaxy Core Prime LTE", I opened TWRP with Home + Power + Volume Up, flashed Xposed uninstaller, and now, my device works fine
I hope I helped you

Help: upgraded P9 Lite to nougat but deleted system and want to Rollback to MM

Hello there. I had recently updated my p9 lite to android nougat from VNS-L31C440B132 single sim to VNS-L31C440B380 with the official uk ee firmware and was absolutely in love with it so far. I had installed magisk and viper4audio with but i wanted to see what other mods like dolby atmos and xtrememusic could do so i added the audio modification library mod so i use multiple mods at once. Dolby Atmos was pretty unresponsive and time i did manage to open it it immediately crashed so i unistalled it and tried out xtrememusic and this is where the problems really began. when i tried to play videos on apps like facebook and youtube they wouldn't load, the video would buffer but it didn't play and on facebook some videos did load and strangely music apps like would play music but i couldn’t hear anything but sound came out of my phone’s music player, i thought the sound mod was messing up so i looked for an uninstaller and found one androidfile host. I booted into TWRP (Openkirin edition), flashed it, and rebooted. I was met with a black screen and the phone was trapped in a bootloop and booted to a screen that told me to do a factory reset which then led into my tarp;I realised the phone got soft-bricked I panicked at this point and the reset didn’t and went back into twrp to try and flash any other versions of the mods to see if it would clear up the problem but it didn’t. I tried to format data but was met with: ‘mkfs.f2fs -t 0 /dev/block/mmcblk0p49 process ended with error: 255’ so I had to go back then i tried to see if i could dirty flash the rom as i still the original firmware i used to update my phone and the stock rom before the update, should’ve realised that wasn’t the best idea; I failed trying to install the main package but the ota update installed with no problems. I booted up the it still wasn’t loading (at this point I had already done a factory reset via twrp and data cache and dalvik) so i decided to see if i could clear the system and then re-install the b380 rom. every attempt i made was unsuccessful as twrp kept saying ‘failed to mount data (device or resource busy)’ or other problems like ‘could not mount /data and unable to find crypto footer’. Eventually I got to where I am now by completely erasing cache, data, system and storage. As there’s absolutely nothing on the phone now as i am on B380 can i just push the nougat firmware to /sdcard/ via adb on my mac and install it as is it or failing that is there any way I can downgrade to L31C440B132? I know to downgrade you need to download an intermediary package specific to your phone build but i looked and I can’t find one for the L31C440 range; I’ve checked Huawei’s official uk support site but the firmware is listed as C900B3000 and my build number isn’t listed. I’m worried that if i do manage to rollback to that specific firmware I won’t be able to restore my VNS-L31C440B132 rom to the phone as it may be rendered incompatible. At the very least I want to know if I can restore the from the nougat rom + update or a sim toolkit i can use to change my oeminfo to C440 and then install my stock firmware. Another thing this is the ota package i flashed: update_data_full_VNS-L11_ee_gb.zip, it says VNS-L11; please let me know if that is going to complicate restoring the rom. Thank you.
Update: I have managed to repair my data partition by doing another factory reset and changing the file system from f2fs to ext4 and the phone is seemingly in a normal state but every time I try to reinstall the main update.app package i get:
Updating partition details...

However the other file, update_data_full_VNS-L11_ee_gb.zip installs just fine:

I'm completely stuck now and really don't know where to go from here as only the other smaller package seems to install but when i try the reboot option it gives me ’no os installed! are you sure you want to reboot?’; should i change the data partition filesystem back to f2fs or is something else wrong with the install? This has been incredibly fruatrating for me. back when i was on marshmallow if i had problems rom-wise, all i had to do was advanced wipe and then just reflash my L31C440B132 stock rom with no problems but now i'm stuck in a real mess as the original rom which i updated to 7.0 is also gone so I've basically got a phone that's upgraded to C440B380 with no firmware at all; I can still boot into twrp but it can't really do anything significant atm. I would like to try debranding it through the rollback package on the official huawei support site but i'm not sure how I can convert my phone's oem info back to VNS-L31 single-sim C440 afterwards. any advice you guys have would be extremely helpful now, especially finding a rollback package to match my build number.
I have been in a similar situation before, but my region is c440 (I changed from c432). I used the C900B300 rollback package in the dload folder on my sd card and updated by the three-button method. I then put the VNS-L31C432B161 update in the dload folder and updated by the three-button method again. Maybe this will work with C900B300 and C440B132?

Like I said i'm being very cautious about about what to do next but how did you manage to change regions btw?
I used the toolkit and oeminfo files from the following link to change the region.
toolkit
Official systems are not for twrp instal! Unpack update.zip and you will get UPDATE.APP, put that in dload folder then on sd card, switch off device, disconnect any cables, hold vol- , vol+ and power button untill installation starts...
Hey man. I am in the exact same situation as you. Have you solved the problem yet?

Samsung Galaxy Camera (EK-GC110) Debloat or Recover [Stock ROM+ (Odin) Root]

My camera got stuck in a boot loop and i wasn't able to find clear instructions on Stock ROM flashing or debloating apps method for the EK-GC110.
Through trial and error, i was able to find a method which i'll leave here for anyone else who runs into the same issue.
Warning:
I'm not responsible for bricking, boot loops or other malfunctions caused by this method. Proceed with care and at your own risk. A backup is always recommended.
Requirements:
Odin V3.0+
Root File
Stock Rom File
Root File:
http://s000.tinyupload.com/?file_id=26455604418346418921
Stock ROM: Google "Updato firmware" to access free Samsung ROMS. Find the model and respective country file for your device.
Odin: Can be found on XDA forums and Google.
Instructions
Download the required files & Odin.
Install Odin.
Reboot device in download mode.
Use Odin to flash the Stock Rom.
Use Odin to flash the Root file.
For debloating, remove apps which do not impact the camera or general operating functions of the android device. This may take a few trial and error runs. You can delete the main contacts app but don't delete a secondary system app labelled "contacts storage". This will leave your Camera stuck in a boot loop. If you're unsure, consider disabling the app instead of deleting.
I also found the System app remover APK from the google play store to be less buggy and more effective than titanium backup. :good:

TWRP for P580 running Oreo?

Is anyone able to run TWRP on P580 running Oreo?
Im having problems with my Tab stuck on a black screen instead of recovery mode.
Please help.
Thanks!!
I found a solution if you don't need TWRP, only Magisk or Root. (Using sm-p580 german version P580KXU1CRJ7)
Short Version:
Install Magisk without TWRP with odin in AP section(google it)
Problem is: Once booted up it will tell you that you have to reset your device because the system recognizes that you modified something.
Solution: Just click on the reset button( Magisk will still be there afterwards).
Long Version
Flash the Oreo firmware onto your device.
Set it up (turn on USB debugging) (or dont, I believe you dont need it for download mode ?)
Unzip the AP part of the firmware you have flashed. You may need a modified version of 7-zip, I needed it, because it couldn't unzip lz4.
Google mcmilk 7 zip and download the github release (I hope I'm allowed to reference it, CREDIT goes to MILKY)
You need the boot.img.
Now install Magisk Manager apk.
Under its settings check " .img.tar" under "return of patched boot-images" (Something like that, mine is german)
Click on install in Magisk Manager apk.
Select make thing with boot img, use the boot.img you have extracted and copied onto your phone.
Magisk will create new patched boot img automatically, copy the finished one u find under your main storage in downloads to your pc.
Go into download mode and flash new boot.img with odin using the AP tab.
Now do the things I described in the Short Version
Afterwards install Magisk Manager Apk.
You need internet connection, because it will prompt you to allow installing additional stuff.
A message from some Security App will appear, that something is wrong.
And your device will get laggy and restart.
After that the lag will disapear
I like to use Bk disabler to remove bloatware/ other stuff to flash or back up your device
(Please dont remove any of the 3 phone apks, on Nougat it worked to remove two of them, but oreo will continuously give an error message <- I found out that you can uninstall two of them, but dont uninstall the storagedial-programm thats what gives the errormessage.)
Hope it will help you!
Worked !!!
Thank you dear. Its worked for mine in p585 oreo android....
Anyone can search mcmilk 7zip in google and download program to extract boot.img.lz4 and get boot.img :good:
use the last TWRP for Oreo.
old version makes black screen or red stripes.
go in download-mode (power+home+vol-) and install the last TWRP over with Odin.
for Oreo use the last Odin 3.13
it tested, i had the same problem :fingers-crossed:
Latest twrp dose not worked on my device but this solution work fine
I can confirm that this method does work. I used it on my SM-P580 yesterday. I would suggest that you first backup your all of your apps, contacts, photos, etc using SmartSwitch. You will need to restore everything after the tablet tells you that it needs to be reset because it wipes everything. After the restore, you will need to enter all of your accounts and passwords again but at least all of the data will be back.

Im not sure if this post belongs here, you link to the T580 TWRP, not the P580.
Is that one compatible with P580?

This one worked for me on a P585Y. You just have to skip the steps below.

It will also show on the Device Maintenance, just ignore the warning.
You can freeze some of the system apps to prevent it from showing on the notification again.

this works great! thanks!
2 side notes on the process:
1. Magisk no longer provides " .img.tar" patched files, so a tool like "Tar-tool" is required to convert the file from the ".img" type. The patched file should be renamed "boot.img" before conversion in order to be succesfully flashed by Odin.
2. like f4vr said, freeze the apps that give the error notification or just disable the specific notification. Hiding them in Magisk Hider does not seem to work
Cheers, and thanks again for the guide!
Hello Gyus,
I managed to root the device with the method posted by @amosdinh (Thank you so much). Now I'm trying to configure adoptable storage. So far I didn't achieve this goal. ADB commands doesn't work and I can't install the ASPlugin.zip needed by Root Essentials to set adoptable storage by the app.
TWRP for P585 is corrupted, gives blue/red lines screen. The dev that maintains the code is absent since march. I'm out of luck on this. If anyone have a idea to get adoptable storage on this device while using Oreo, please comment.
Thanks!

Just renaming magisk_patched.img to boot.img and adding to .tar file by 7zip worked for me.
We should ask a dev to update twrp for android 8.1

I have the same problem. It just keep getting to the bad TWRP, it seems that it does not work with the SM-P580. I had to flash stock firmware to get it back to work.

Really wish this wasn't the case. I'd actually keep this thing if it had a working TWRP.
On my SM-P580 I used Odin and TWRP I don't get the black screen but when I reboot to get into TWRP recovery mode it shows the padlock and says swipe to unlock. Tried many times bit cannot swipe and cannot get past this. All I want is to be able to use the SD card as internal storage. HELP???? Thanks!!

where can i find stock firmware?
I've just installed magisk using TWRP via command line. P580
I've just installed magisk using TWRP via command line.
Read the entire post before trying this yourself.
I installed the latest TWRP, the one that bugs and doesn't display anything, this allows to root without wiping data. I'm running the latest korean firmware for P580.
Just do this:
1. Launch TWRP and INMEDIATELY LOCK YOUR SCREEN. (I got ghost stripes that disappeared after 2 days when testing this, work with low light so you can notice your screen whenever it tuens on) Please don't forget this point, don't [temporarily] damage your screen as I did.
2. adb push Magisk-v[Current version].zip external_sd
3. adb shell
4. twrp install external_sd/Magisk-v[Current version].zip
After this you just need to install MagiskManager-v[Current version].apk and you will be all done.
But there is one thing...
If you ever get into recovery mode, there is no way out without using adb as far as I know. You can launch download mode and cancel it but you'll boot back to TWRP.
When in twrp touching your screen or any button will wake the device up and will start burning the ghost image to your screen.
So if you know of a method for rebooting to system without using adb, please let me know.
Also a solution for this would be to flash back the stock recovery, wich may or may not force to wipe system, that something that needs to be tested tho.
Update: Ok so, you can use a handy tool called MTKroot on recovery.img.lz4 to get recovery.img, then use 7z to pack it into a tar file and flash that tar file with odin (AP, same as TWRP)
This way you will not have a 0.001% chance of random boot into recovery mode and damage your screen

Accidentally deleted G Play store

So I accidentally deleted the Play Store after rooting my phone, and factory reset doesn't bring it back. I got an apk and installed it, but it wouldn't open past loading for a second and then it would tell me every second that "unfortunately Play store has crashed". I managed to get play store to STAY open by deleting the cache for the play service, play store and play store framework, but then it threw a DF-DFERH-01 error at me (deleting the play store cache again didn't resolve that issue either.) I'm at wits end, I'll do anything to get it back. I'm considering reflashing my moto to FULL stock, not just boot.img stock, but I don't know if that'll help it at this point or if it'll just make it worse.
edit: well, I answered my own question. the stock firmware for my phone, the RETUS firmware, has two XML files in the zip. the flashfile.xml has a list of what to do in fastboot to reflash your system to full stock, but the XML can't be run like a batch file so I set to parsing through it manually and doing the install.
in my specific case, where my phone's bootloader was unlocked and I could flash custom stuff, the process was pretty simple.
you reboot into bootloader, fastboot all of what the XML tells you to fastboot, and reboot into the os. it should be fixed. I think I'll try to put up a more detailed summary of what to do in a more appropriate board.
