Can anyone tell me how i write a ROM to an SD Card of a unrooted device - i cant access the SD Card on the device, as Android wont start up after a resetting of the device - so i am resetting the ROM. Can it be done on my PC, OR another Android device - is there anything i need to do to the SD Card - make it bootable or format it in a particular way Any help would be appreciated !!!!!!!!!!

Key word “unrooted”. You require superuser access on the phone. Unrooted means superuser access is locked. Rooted means superuser access is unlocked.
