I was looking for answer but didint find it.
Thank for a help.
Unfortunately that cannot be done, once you have upgraded to 4.3 MK2 you cannot downgrade.
But there are plenty of excellent custom roms which are 4.3 MK2 that you can flash.
NOTE: if you have flashed the official Tmobile MK2 4.3 Odin flash firmware/rom OR if you
have allowed the OTA update and or if you upgrading using KIES and your phone is not yet
rooted and does not have any custom recovery or custom rom in it then you don't need to worry
about your warranty, it will stay GOOD as long as you do not ROOT the phone and as long as
you do not flash any custom recoveries, roms or kernels.
Have a great day, enjoy!
Don't forget it takes less time to click the "THANKS" button than to type "thank you".
(unless you type very fast).
