Not able to root or install TWRP on Galaxy S6 5.1.1 (SM-G920I) at all.

Hi everyone,
Trying to root my Galaxy s6 SM-G920I India version but no luck. Had to restore stock firmware thrice today. Every time I used ODIN 3.10.6 with Unibase or Unikernal it would say kernel is not SEAndroid enforcing and stick to a bootloop. If I use the CF auto root method it says Recovery is not SEAndroid enforcing and again bootloop.
Trying the alternative method of installing TWRP also does not work and I get the same recovery enforcing message and bootloop. Please help. R/L is off.

I had the same problem with Indian firmware. The latest one.
I quit trying to get root.

I have the issue too guys. The newest UAE firmware(CSC XSG) is not letting the TWRP stick after flashing with Odin. I've asked for help over in the Help & Troubleshooting section. Hopefully we can figure this out.

I read your blog. The thing is that I can't root the India firmware. Is the firm I'm using and I don't want to change it cause it's working really well.
But seems that is unable to root. And I want to erase some bloatware to make it lighter
Thanks anyway for your help

When you rooted your S6 G920F that time was your phone having 5.1.1 android and DOL5 bootloader.

I tried this method on this website but no luck.????

There is a thread on xda about how to root DOL5 formware by an INDIAN USER USING G925I.
Not all had success with it. I would suggest sticking with DOK9 firmware and wait for a few days as android 6.0.1 has started rolling already in Korea for s6(both variants)
The changes between DOK9 and DOL5 is not huge and not worth an upgrade

I have rooted my s6 today only with 5.1.1 Android and DOL5 bootloader. I flashed twrp
down below is link. You will face a little bit of problem while going in recovery but dont worry you will be able to enter after some tries. When u enter there flash super su 2.66 and u have rooted your s6.

I did but there are about 10 different versions to choose from for the s6 and they don't all work. I really don't want to end up flashing it. I still haven't made a back up of my phone so I need to solve this quickly

They only work if you are rooted. If you are not, you'll have to root your device first.

I am rooted with a kernel mod. But anyway I figured it out myself

Recovery for Marshmallow?

Hello all! I recently updated my Spring Note5 to Marshmallow! I quickly installed the Aurora Kernel to root it and got xposed installed via FlashFire. I was just curious as to if there was a Custom Recovery for marshmallow yet? I tried the latest TWRP and got stuck in a bootloop (soft brick). I was able to recover it luckily. Is there a working custom recovery yet? Thank you!

Here is the TWRP link for the Note 5 running marshmallow https://www.androidfilehost.com/?fid=24459283995314665

Twrp is working but I got stuck in a bootloader trying to flash the twrp update with flashfire Odin is best way I had to use Odin to recover out of the bootloop

The file that I posted you don't need to use Odin or flashfire just install the Zip file then you can boot the cell into TWRP

SM-G920F Downgrade from 7.0 to 6.0.0.1 failed

Hi XDA Members,
I have a very curious problem and hope somebody has an idea what could be wrong.
I have a stock phone that has been updated by a friend to 7.0 but now he wants to go back.
I have flashed a one part stock rom with Odin with complete sucess but after reboot (even showing the erasing process)
the phone boots up and 7.0 is still there and even all the apps and data are still available.
So I tried a 4part stock rom and to my surprise the same thing happened. Odin finished with sucess, phone reboots now it
even installs the bloatware apps and yet it is still running 7.0
I am loosing my mind here. Do I need to flash a pit file? Do I need to root before I flash? What am I doing wrong or will I be stuck with 7.0 forever now?
kind regards
Piko

You need flash rom which starts with G920FXXU5D or G920FXXS5D if you want to downgrade to 6.0.1
Btw, you don't have to flash 4 part rom.

I have just flashed the G920FXXU5DQA7_G920FDBT5DQA3_G920FXXU5DPL3_HOME.tar.md5 but now if
I start the phone it says "SYSTEM UI STOPPED" when I hit ok - it just says this again and again. Guess this was the wrong
rom once again? I just hope I did not brick the phone yet. Should I flash it again with another ROM? Could you maybe point me to the correct rom I need to download?
many thanks in advance

And is there anything good I can do for you to say thank you for helping me out this much? Seriously you helped me soo much.

My main reason is that they changed some core things. I now cannot stream anything from the phone (screen capture) without root. Also some oculus apps just keep crashing all the time.

Hello I have had the same type of trouble only with mine is >/
I have a Samsung Galaxy S5 from Walmart. It's the Straight talk variant SM-S903VLUDU4APH3. MY phone came with 6.0.1 Mm. I flashed the stock rom 4.4.4 kk using Odin3 V.3.10.6 but upon completion of a successful flash the phone does the reboot process but boots into factory recovery and says installing system update. The says erasing then reboots to where I started from same rom, it's like it allows the phone to get the update but then reboots and does a factory reset.

g955f latest firmware but need to downgrade to 7.0

hi all
i got a samsung s8+ with G955FXXU2CRED_CL13569719 firmware on it.
How can i downgrade it to android 7.0?
If i flash 7.0 software i got failed when i flash BL
If i only flash AP the device shows encryption failed and then then i get boot loop with erasing android icon.
Hope some one has a solution here.

I downgraded from 3 previous versiones of Oreo, didnt try agaik with the later ones but i read that the new boatloader in kinda tricky now.

Stability?! Battery?! Lags?! Connectivity?! Source?!
Remove/change PDA reg?! Erase data?! (CSC issue)
Is this rom Nougat or prev Oreo version?!
Some info about this rom?! It comes from some forum's discussion?!

Odin flash works fine but then am on what seems to be bootloop...am stuck on screen with "FACTORY BINARY" message showing and big progress arrows now for 20 minutes...is that normal to take so long?
