Hey all.
I have an Australian SM-G920I on Telstra and have recently rooted using the CF Auto Root method (successfully). I tried flashing TWRP 2.8.6.0 the other day and it wouldn't work. Browsing some threads on here and @Hero mentioned he managed to get TWRP to work once he updated the firmware. However, I can't use the OTA update method as it says that I've modified my OS in an unauthorised way.
Help?
Like in the case of the nexus 6, with lollipop some changes were introduced to the ota checklist procedure. If ANY system files or recovery are modified the ota will fail.
Nothing short of using Odin to go back to 100 %stock will help you. ( and that's assuming Knox plays no role in the ota)

Odin is your only bet to update firmware if you're rooted. The good thing is you can usually update radio (which imo is the most important thing) separately via Odin without having to flash the entire package.
I downloaded this firmware https://www.androidfilehost.com/?fid=95916177934555710
How do I go about flashing it? I've unzipped the files onto my computer but can't find the .tar file to flash with Odin.
Hi! Guys I'm using the tmobile Gs6 do I need to update my firmware?If yes which firmware do I want to update it too. Thanks

I've found a couple of ROM's and the root method did work but I am unable to get a custom recovery for the model I have and I don't want to be stuck with a brick.
Model: SM-G920i and attached is a screen shot. I'm just hesitant to try anything because it's a generic S6 not tied to any of the major carriers so flashing back could be difficult as I don't have the custom ROM.
Anyone?

You can also use flashify from playstore for custom recovery, or pingpong root for rooting.
Flashing custom recovery will void your warranty.
What firmware are you on? I have the 920i, and I had problems flashing twrp until I upgraded my firmware with kies and odin.

What I did was flash it via kies and it went back a stock non carrier branded version and then twrp took and now I'm enjoying my custom ROM.
I got the Galaxy S6 yesterday and coming from Nexus 5, I wanted to remove the existing bloatware by flashing the XtrestoLite Deodexed ROM. This one here: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/rom-xtrestolite-deodexed-mod-edition-1-3-t3119968
I'm haven't had much experience in rooting and it's my first time flashing a custom ROM. The phone was running on Android 5.1.1.
Apparently I failed. I started with CF-Root but I wasn't sure if it was done correctly. This was followed by TWRP 2.8.7.1 . Then I tried booting up the phone and the boot logo just loops. I tried to wipe the cache as well as the Delvik-cache through TWRP but it's still the same. Then I tried to flash the stock ROM that I found online but I got the error "Nand Write Start" followed by "Fail". I seem to have tried everything and now I just want to get the phone to work again. It shouldn't be so hard.
Someone help me please :crying:
Have you tried to flash the stock rom via Smart Switch software? There's an option in the top of the window where it says "More" called Emergency Recovery. When my S6 bricked nothing but that did the trick, you should give it a try.

How did you do it? I've installed the Smart Switch software but the device doesn't appear under the list in emergency software recovery, so I can't proceed.
Edit: I managed to do it through initialization. I'll update when it's done.
Edit 2: It worked! Thanks so much!

Your PC is recognizing your phone? If not maybe you shall update your drivers first. My S6 is the same model number as yours and it does appears in the Emergency Recovery list.
Another solution could be trying to flash using another version of Odin; I saw a similar problem on another forum and it was solved using Odin 3.10 to reflash the stock firmware.
Also remember that you can't downgrade your firmware once that you are on 5.1.1, no 5.02 or so allowed.

By the sounds of it you're able to boot into twrp? If so then simply boot into twrp, connect to your computer and copy a flashable rom to your phone and install it using twrp instead of odin

How could I transfer the flashable ROM to the phone when I can't have it boot up to connect to my computer?

Since you're using the same model as mine, what are you running on your S6 right now? Are you able to root and flash a custom ROM like XtrestroLite onto Android 5.1.1?
Can you guys help me check if this post has the correct steps or is it missing anything like bootloader and root?

Actually yeah. Earlier tonight I flashed XtreStoLite over stock 5.1.1, but I must confess it wasn't as easy as I thought, mainly because I didn't followed the steps in the right way and I ended up having to root my phone through installing UniKernel, which is pre-rooted and that did the trick for me, because I got stuck in the Samsung logo right after I tried to flash with CF-AutoRoot, needless to say I obviously couldn't root with that method and had to reflash stock 5.1.1 firmware to unbrick my phone, install UniKernel, and after that I was able to enter my phone config, uncheck the reactivation block under Find My Mobile settings (which was the reason for me to get stuck at the S-logo) and then flash through Odin XtreStoLite deodexed and Xposed FW too, so I can tell you for sure that SM-G920I can run XSL like a charm.

1. So what is the correct order?
2. Did you have to manually unlock bootloader?
3. And is it a must to install uniKernel in order to root the device?
I have no idea how to proceed now.
This requires a lot more effort than I thought :fingers-crossed:
1. The correct order apparently WAS to flash 5.1.1 bootloader and modem over 5.0.2, then root, then TWRP, then flash XtreStoLite, or at least that was what I understood from Edgar's guide (as you can tell, I hurried myself too much and was to excited to flash XLS, so I didn't read properly).
Since I (and I think you did too) installed stock 5.1.1 first, there was no way to autoroot nor ping-pong root the device, that was the reason I got stuck in the Samsung logo screen after trying to autoroot, so I had to reflash stock 5.1.1 to regain access to the device settings/Find My Mobile as I explained before, after that I flashed UniKernel and that did the trick, no other steps were required to achieve root access beyond this point.
2. I didn't had to, but your carrier may have locked yours. My device is a SM-G920I (as yours) from Telcel carrier, so I can tell for sure.
3. There are several others way to root devices running over 5.0.2, but according to my personal research there aren't much options on 5.1.1 other than flash a pre-rooted kernel, but UniKernel isn't the only pre-rooted kernel, so you can choose whichever you like the most.
If I were you the first thing I'd try, as I said earlier, would be to switch to another Odin version or another firmware (as long as it is 5.1.1) and if that don't do the trick, then I'd update drivers and try via Smart Switch again.

What did you use to root? May I ask for the link? I just tried flashing CF AutoRoot and now I think it's bricked again. (RECOVERY IS NOT SEANDROID ENFORCING) I'm thinking it might be due to incompatibility because I got it from here (https://autoroot.chainfire.eu/#odin) and the Android version states 5.0.2.

Yep, that was the exact moment where mine got stuck too, as I stated before at that time I had to reflash stock firmware. The trouble is caused by CF-Autoroot, it won't work at all when you're on 5.1.1 (at least with SM-G920I) and if you try to root using this method, you'll get stuck with the message "RECOVERY IS NOT SEANDROID ENFORCING". You'll have to reflash to stock too, I'm affraid...
Flash UniKernel via Odin once you're on 5.1.1 stock again and see the magic happen. Once you have root access, gained by this kernel, you can install TWRP and flash XtreStoLite or any other rom you may want. Here is the direct link to the post: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/kernel-stockmod-kernel-t3100395
Hope you get lucky.

I just did that before you suggested it and it worked! I was so elated! I love you bro (no homo). Our situations are identical. Now I have XtrestroLite running on the S6! Thank you so much!
Simply put:
1. Update bootloader and modem
2. Install TWRP without root via Odin
3. Install UniKernel via TWRP
4. Install ROMs!

Hi,
I have a G920F, I was rooted and want to go to stock again. I have restored the device with Smart Switch, but now I am unable to flash any other rom. I have downloaded 3 different roms from Sammobile and get sw. check failed device 3 binary 2 at everyone. The current rom is form Italy Wind the latest OI9. Any suggestions?
Thanks in advance.
Hi, probably you trying to install oldest firmware 5.0.1, download the latest firmware and try again. You are with 5.1, right? This error on odin happens, because you cannot downgrade the firmware. Hope this helps.
I think you can not downgrade even if it is the same Android version.
If it detects you are on a newer bootloader it will give you that error.
What I belive you can do is to extract the bootloader (sboot) and modem from the .tar file and flash ONLY the system through Odin.
Don't know exactly how to do that because I haven't done it but I think that would do; you will have to search and read my friend.
You will have the stock firmware but with latest bootloader and modem.
Hope this helps.
Note: As far as I know this will work if its the same Andorid version; you can not have Android 5.0.2 with 5.1.1 bootloader.

Hi,
I have tried what you said, but no succes. The firmware was already recovered with smart switch so the bootloader is the latest.

But did you try to flash without the bootloader and modem?
This is what is installed on my device: TWRP 3.0.2-3 / android 6.01 (I THINK it's a bit modified rom) / SM-G930FD
I rooted asap I bought it few years ago, I want to update to the latest Nougat version 7.0.0 (I think the 7.1.2 is not officially released, right?)
All I need is stock (slightly modified is also ok) + root and don't mind formatting it to start from the scratch.
What are my options and/or what should I do? Thanks for reading!
Flash the latest stock ROM with Odin, then root.

Thanks for the reply.
Can't the TWRP do the same thing? If I flash using the Odin, will I lose the TWRP?
You need to use Odin to flash a stock ROM which will cause you to lose root and twrp.

I recommend matching the ROM to the original carrier.

It's an international unlocked version, does it have a "carrier"? How do I find it? I'm located in Japan and imported this phone.
You can install the Samsung Phone Info app from the Play Store to find out the csc and match that to the ROM.
