I have a S4 on MK2 on AT&T

The fact that I am stuck on TW is depressing. And to top things off AT&T has disabled WIFI tethering, which I was using occasionally.

Is it possible to ODIN back to stock and the firmware the phone came with a year ago?

Is it correct that the originally firmware would allow me to flash Cyanogen / Task etc?


What firmware do I need to get? I understand MF3 is also bad?

As stated above, you can't downgrade. You can enable tethering by the thread in the general section and use Safestrap to change to other TW ROMs like Foxhound which has AOSP theming.

You could only downgrade from 4.3 if you were using the leaked 4.3 ROM with the MJB bootloader. The official OTA 4.3 updates cannot be downgraded as Samsung blew a "qfuse" with this major (4.3) update preventing reversion of the bootloader.

However, you can change or downgrade the actual ROM filesystem, provided that you keep your MK2 boot loader in place. That means that you can't revert to a pre 4.3 stock ROM but you can use custom ROMs that are 99% stock while restoring the functionality that you'd like to restore.
