Question Unlock, Root and Debloat Galaxy Tab A7 Lite

[thatha]

I just share my experience. Do it at your own risk

I. Unlock bootloader

1. Enable developer options by tapping build number 7 times

2. Go to Developer options, turn on OEM unlocking

3. Turn off Tab A7 Lite, connect it to the computer while holding Volume Up and Volume Down keys until you see the bootloader screen

4. Long-press Volume Up key to enter Device unlock mode

5. Press Volume Up key to confirm and unlock the bootloader

Done



II. Root

1. Unlock bootloader (skip this if you have done it)

2. (On PC) Extract boot.img.lz4 from Stock AP...tar file, then copy it to Tab

3. (On Tab) Install ZArchiver to extract boot.img from boot.img.lz4

4. (On Tab) Install Magisk and patch the boot.img that you have just extracted from step 3

5. (On PC) Copy magisk_patched.img (in Tab\download) to pc, rename it to boot.img

6. (On PC) Use 7zip to pack boot.img from step 5 into boot.tar

7. (On PC) Use odin to flash boot.tar from step 6 (in AP slot)

8. After Tab reboot, open Magisk, update to newest version, open again and let it install something then reboot

Done

In case you don't want to do a full step by step as above, you can use my already patched boot.tar below, just download and flash it via odin. After flashing and reboot, open Magisk, update to newest version, open again and let it install something then reboot

Sorry, I did put the tablet in download mode, but it says the boot image cannot be flashed with odin becaouse its custom binary even if developer mode is on and OEM unlock is on... Strange! Any Ideas?

What binary is your Tab firmware ?

 

[Bercsenyilaszlo]

Sorry it was alright I just didnt press long enough the volume up button its different from a short press when unlocking the OEM.... Thats all a long press needed instead a short one.. Otherwise boot loader will stay locked.

Thanks for the thread GREAT WORK!

Yes if I have some free time to download your firmware. If you can extract boot.img.lz4 from your firmware and send me, I can do it soon

Hello,
thank for your work I succeeded with root but I mistakenly installed a faulty twrp which bricked the tablet. I have access to download mode but I can't reinstall a functional version ("security fail tip) the only thing that odin accepts is your great work "patched boot.tar" but the boot still blocks. an idea to unlock it. thanks in advance

I also bricked my tablet, and the only firmware ODIN accepted was downloaded by Frija. Got errors from Sam firm and Galaxyfirm.

I think you should download and flash latest firmware. You can download from this site:
samfw.com

 

[antineas]

Hello,
thank you for your help i have repaired the boot. it was a question of firmware indeed but beware for tablets version T225 "N" the firmware is not the same and is more difficult to find. they are not offered on dedicated sites.
