problem when trying to flash miui rom on my galaxy grand cm11 uwhen I flash it and reboot my phone it hang on samsung logo screen and I tried to flash cm 10.1 too the same happened??
That's because CM11 is based on 4.2.2 firmware while MIUI and CM10.1 are based on 4.1.2.
So when you want to use CM11 upgrade to 4.2.2 firmware through Odin, and to use MIUI and CM10.1 (and ROMs like PACMAN, SlimBean etc) downgrade to 4.1.2 firmware.
