Can I downgrade from V18 to V13? Or do I have to flash other firmware for bootloader/modem?
Edit: I found the answer myself -> One has to downgrade also the bootloader.
- Download latest 4.4.2-Stock-Rom (get from SamMobile)
- Start phone, enable developer options, enable USB-Debugging
- Start phone in Bootloader-Mode
- Flash 4.4.2-Stock-Rom via ODIN (if fail, use PIT-File to unbrick)
- Flash TWRP
- Start in recovery
- Flash SuperSu.zip
- Flash Omega V13
