//G891A\\ Oreo 8.0 Latest Stock Odin files G891AUCU6CTB1

[stek-kravari]

Full ODIN stock ATT files.
Download one file, extract to 4 files, put in ODIN and flash.
I take no responsibility if anything goes wrong. You don't need to be on certain baseband to flash this, you can flash this directly from any baseband version.

I don't think you can root it, most of the developers don't even bother finding root exploits because the bootloader is locked. You can try something yourself but that may brick the device

I'll manage. Much appreciated. Running flawlessly.

Thank you very much! I originally did an OTA from Nougat to Oreo. I'm not sure if it's my bad luck or if someone else can relate, but doing an OTA to a whole new version is super sketchy. I much prefer to flash the new version, and this did the trick! All the weird little ticks my phone had are gone! OR maybe it was about that time for a factory reset :silly:

EDIT: Also thanks for the latest OTA! Does anyone know if the Russian cloud guy gave up? Right now I am pretty sure this is the only place to get it...

No problem. Glad that your phone problems are gone after flashing this firmware. From now on i will be uploading OTA updates for this device.

I was stuck at at^t logo on nougat, I had nothing to lose so I tried it and flashed the first file successfully, what to do next ? How to flash the other files? Do not lough at me , I am a newbie .
Do I have to flash first G891AUCU4CRH1-to-S4CRJ1 and than G891AUCS4CRJ1-to-S4CRK1, or I can flash directly the second one G891AUCS4CRJ1-to-S4CRK1?
How to flash them, through recovery ?
Thank you very much

Yes you need to flash first G891AUCU4CRH1-to-S4CRJ1 and than G891AUCS4CRJ1-to-S4CRK1
Here are the steps:

1.) Turn off the phone. Hold down Volume Up + Home + Power until you see a little Android guy. It will say Applying System Update or something like that possibly, and just let it do it's thing until a menu comes up.

2.) Select "Apply update from ADB". You can scroll using the volume buttons and select using the power button.

3.) Make sure you have ADB and the proper drivers installed on your PC:
http://dl.adbdriver.com/upload/adbdriver.zip

4.)Put the firmware in the ADB folder. You can rename it to anything easy to remember like "FIRMWARE".

5.) In the ADB folder, hold SHIFT + right mouse click and choose "Open command window here". Then type the command "adb sideload FIRMWARE" (where FIRMWARE is how you named your file).

6.) Wait patiently.

7.) The phone will reboot and will hang at AT&T logo. This can take another 10 minutes, just wait until it's done

Do I have to extract the zip, or it must stay archived?
I tried it without unzipping and cmd says cannot read FIRMWARE
Thanks

You don't need to extract it, the error part cannot read FIRMWARE is beacause you didn't rename your archive to FIRMWARE, and you don't need to, that is just example in the process.

adb sideload G891AUCU4CRH1-to-S4CRJ1.zip and after the phone updates and restart sideload the newest
adb sideload G891AUCS4CRJ1-to-S4CRK1.zip

In fact I renamed it just as you said, the zip was in the same folder as adb, maybe I have to try on another pc later, the problem was that when I installed adb it said adb already installed on this pc, so maybe there was an older adb installaion on my laptop and something went wrong.
Will try later on another pc.
Is it possible to flash it through recovery from sd card without using ADB?

Yes, I think you can use the option from recovery "Apply update from SD card"

Been a while since I messed with my phone, last time I was looking at doing this there were warnings of not being able to return to nougat if using newer BL's, is this still an issue or are we all clear now?

Also, i'm 99% sure I have had this phone rooted at some point for a while last year for a while before I had to factory reset. OP you sure about the bootloader comment you made? I could def be wrong, but I think it was this phone.

If you flash bootloader with updated binary, you cannot install older bootloader. About the rooting part im not 100% sure, there are no active developers for this phone, mostly because the bootloader is locked, and thats why there are no root posts, its hard to find root exploit, if you can remember how you achieved root status please share it with us

Hi guys!
I have a doubt... I'm in the baseband version G981AUCU2CRC7, so, can I install the G891AUCU4CRH1 baseband and then upgrade it until the G891AUCS4CRK4 baseband? Yes, I know that it says that I can install it from any baseband version but I just want to avoid any unnecessary risk.
Thank you! ?

I haven't flashed anything in a while, so can I update from Marshmallow using this or do I first need to be on Nougat ? do I need to choose just one file for my phone ? I have the AT&T version SM-G891A on 6.0.1, G891AUCU2APK2 Baseband ? also, is Oreo doing good with speed of the device and battery or is it worse than Marshmallow ? So right now, I'm torn between Updating to Nougat and Rooting, or updating to Oreo without root, I don't really care much for rooting, my biggest concern is speed and battery life, I'm on stock Marshmallow and everything is ok and I get 15h 18m (9h 13m Active) , I wanna update, what do you recommend ?

 

[hudtwalcker]

Damn I feel like such a noob, I've updated to Nougat before and rooted my device and gone back to Marshmallow but now I can't remember for the life of me how to do THIS, I wanna update to the latest Oreo, is there a tutorial on how to do this ? I'm not understanding which file I need to download or how to do it, please help I'm on Marshmallow 6.0.1 and I just restored it to factory. Baseband G891AUCU2APK2 kERNEL VERSION 3,18.20-9489319 BUILD NUMBER MMB29M.G891AUCU2APK2
