Locked on stock recovery software? Even after flashing clockworkmod, when I go into the recovery menu after booting, it just gives me the stock recovery system. Help? I've also tried with twrp, no luck.
This is because most stock systems will flash the stock recovery on boot and/or your bootloader is locked (and prevents writing to safe partitions).

Please follow this instructions from CM; They are working, I already tested them:
