downgrade from 4.4.4 (TGP) - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

HI there i want to downgrade from 4.4.4 (TGP rom) to 4.1.2 (stock) to do that "how to" that unlock my phone..
The way i want to do it is by "puting" 4.1.2 oficial firmware via Odin... Is this the right thing to do?
Thanks!

due to the changes in the bootloader it's a little difficult...what bootloader you have? 4.3? the one with knox counter? but not with secure donwload? if yes you need 4.1.2 with 4.3 bootloader....search forum and you will find it.

Hey, i have used these files to flash with odin and downgraded successfully from 4.3 to 4.1.2 http://forum.xda-developers.com/showthread.php?t=2023527.
Remember that this is only FOR I9305 and not for I9300!
You will still have KNOX bootloader.

Downgrade from 5.0 stock to 4.4.4 kitkat

Hi All,
I had S5 on 4.4.2 . Upgraded to 5.0 in following manner using OTA packages - using stock recovery
4.4.2 -> 4.4.4 -> 5.0
I would like to downgrade back to 4.4..4
Which method can I follow?
Want to downgrade because QXDM mode is not working in 5.0
Thanks
Not possible yet , I can't find a 4.4.4 firmware or tar file to try either . I Ave tried everything else I could find
The bootloader on 5.0 makes it impossible to downgrade. There are multiple threads about it.
No solution as of yet, and possibly never will be. They locked the piss out it.

[Q] Lollipop 5.0.2 to 5.1.1 update process

Hi, I'm still on a pre-rooted 5.0.2 stock rom based on this:
http://forum.xda-developers.com/z3-compact/development/z3c-usa-variant-lollipop-pre-rooted-nut-t3071069
My question is: How would I go about updating to 5.1.1 without losing root? Would I have to flash the 5.1.1 firmware via Flashtool again? If so, does anyone have a stock pre-rooted US firmware? I also have a locked bootloader, and I'd prefer to keep it that way for the better camera. Thanks!

Downgrade to NCE

I have a Galaxy S5 (G900A), rooted on Lollipop 5.0 (0F3) using prerooted firmwares to upgrade from rooted kitkat. My bootloader version is still OA1. I want to downgrade now to kitkat so i can use safestrap. I was wondering if i could downgrade using the G900A_Downgrade_to_NCE.tar mentioned here and here, since i still have to OA1 bootloader, to downgrade without bricking my phone.

Yes you can use that downgrade file. I have used it many times. Your phone might run real laggy though after you downgrade. There is a thread somewhere that shows how to fix that issue. I'll see if i can find it for you.
