If i'm on 4.2.2 and i am rooted and i have knox warranty void : 0x1 can i flash any 4.4.2 with odin ?
Keep up the good work this is a great Rom.
Unlock the bootloader via Fastboot the instructions are on this site then your be able to flash the stock rom.
Instead of flashing the Vodafone bloatware firmware flash the latest UK BTU firmware which isn't full of crapware, using this firmware you wont need to flash a pit file.
You have already been given the answer in this thread, after the install go back into download mode and flash a pit file via odin, your phone will then work.
