[Root][SM-T380][SM-T385] Samsung Tab A 8.0 (2017) Root Tutorial

[shahmir_k]

Method was kindly shown to me by user Mefody in answer to a thread I posted.


Rooting SM-T380/T385 via Magisk Manager APK v.5.5.3 & Magisk 15.2:

1. Unpack stock firmvare ***.tar.md5 that is currently installed on your tablet (they MUST BE the same!!!).
2. Then unpack AP-block from step 1 to obtain "boot.img" file.
3. Download & install on tablet Magisk Manager APK.
4. Put "boot.img" on SDCARD.
5. Run Magisk Manager, in setiings set "Patch kernel", then setup the Magisk zip (Wi-Fi must be connected to Internet ).
6. When asked, point Magisk Manager to place on SDCARD where "boot.img" saved.
7. After some time You will get "OK".
8. Find on SDCARD file "patched_boot.img". Copy in on PC & rename to "boot.img". Then archive it to "<any name>.tar".
9. Set tablet to download mode & flash above tar-file via AP-slot of Odin-programm.
10. Tablet will reboot & ask to wipe all data to factory's params. Do it... Be noticed, that all passwords, setting, google registry will be wiped.
11. After wiping & rebooting install Magisk Manager APK again... And YEAH!!! You got root!

Thanks for creating this thread. I used the original thread to root my tab, so seeing this as its own thing will be helpful to a lot of people.

Now all we need is TWRP and we'll have Xposed and custom rom support

Could you clarify on these two steps?

1. Unpack stock firmvare ***.tar.md5 that is currently installed on your tablet (they MUST BE the same!!!).
2. Then unpack AP-block from step 1 to obtain "boot.img" file.

You have to open the stock firmware with an archive manager like WinRar or 7zip. Inside you should find an AP-Block folder. Inside of that should be your boot.img file

Thanks, where can I find the stock firmwares?

Here is another problem
Is OEM unlock in Developer Section required to install patched kernel and TWRP with Odin?
I can't find it even it's updated.

Does anybody know if this rooting method will work with T-585 on Android 7.0 (January 2018 update)? I guess KNOX will be triggered, right?

I say the root is TOTALLY FALSE!!!
I have been waiting for two week and there's no update to enable OEM Unlock option.
I have returned the unit with restocking fee.

Have you tried this method even without the option in developer settings to OEM Unlock? On my SM-T350, I don't have the option to OEM unlock either. But I can still root and install TWRP anyways.

I tried to flash modified kernel or TWRP with Odin and I got error
Only official software can be installed.

Perhaps someone could provide boot.img files and links here?
I for instance found no matching firmwares for mine. The one that had both matching versions numbers, said it was for Cellular US. This is a wifi only model. Confused
Thanks

I have that original boot.img and magisk modified one.

 

[mingkee]

There's a 7 days waiting period after you turned it on the first time regardless reboot or not.
I will make a instruction how to root and I will post kernel and modified kernel.

I didn't realize it was so effortless to pull the boot.img out. BUt, until I have that oem unlock option in there, doesn't matter.

Come on, 14 days

Finally, mine has successfully rooted with Magisk.
I will post a guide.

When I try to flash the archived boot.tar via Odin it just hangs and sits there. Any help would be much appreciated. Thank You.
