So I have a Galaxy S3 i747(at&t) rooted and with an unlocked bootloader. Currently running Cyanogenmod with TWRP recovery.

I'm trying to downgrade back to Touchwiz for the purposes of using an unlock code that AT&T provided me with (apparently it doesn't work with AOSP roms). Any chance I could safely use TWRP to flash the stock rom, and then use TWRP to flash Cyanogenmod back right after?

I've read from here and there that flashing the stock room with an unlocked bootloader and/or flashing the stock room NOT using Odin could brick the phone, etc etc.

Sorry if this question has been answered quite a few times, I've seen quite a few different answers regarding this floating around.

Cheers

You must flash stock ROM via Odin
After root again and flash custom recovery

Guess there is no way to NOT use Odin :/

Do I have to relock the bootloader/unroot the phone before I flash with Odin? Also, will it put the phone back to Stock Recovery or can I keep TWRP?

And one last thing before I go through with this...

Is this^ a possible way to go back to stock without going through Odin and losing everything? (Remember, I'm just trying to get to a TW based rom so I can use the unlock code). And if so, can I just flash that rom with TWRP?

Try and backup your data before u do ..if it helps
Your phone may end up in bootloop if u try with twrp

Via TWRP you are able to flash backup of stock ROM. If you have it
