Hello,

Nothing. You already installed the newest Knox Bootloader included with the Firmware and it can not be downgraded. If you do downgrade the Bootloader you will brick your phone. You can flash "ROMS" ( not Firmwares ) all you like from previous builds meaning you can flash a Custom 4.2.2 Rom but you can not downgrade the newest Knox Bootloader you installed.

Really?
I have now the TPH beta installed, but is only a beta, and i really want to return in 4.2.2 firmware, that's absolutely a s*it.

So can't donwgrade with or without root, cannot downgrade bootloader, nothing to return to stock 4.2.2?

All the lag from 4.2 just isn't worth going back. I had to go back to my iPhone 5S until the 4.4.2 came out. Now I'm on 4.4.2 and back on my android and loving it. Never want to go back to the iPhone again.

No!! he can't use odin to flash a 4.2.2 firmware because he flash the 4.4.2 kk firmware with the new knox bootloader if he try to flash an older firmware he will brick his phone. @corrystile you can use the MegaFire v11 to go back to jellybean 4.2.2 thanks to @megalomanic14 this is a TW base rom and it work on both 19200 and 19205.

And the rom also works on the i527m mega (Canadian version).
