i am currently using razr m update to 4.4.2 firmware is 183.46.15 bootloader locked but i want to install custom rom so in order to do so i tried to downgrade using rsd lite to flash 183.46.10 firmware but it gave error and flash failed...please help me how to unlock bootloader.
you can not downgrade
only way to unlock the bootloader if on 183.46.15 is sunshine app
free to test compatibility, $25 to unlock
I would root with hydrogen peroxide, even though kingroot or temporary root should work too
