Hello,

Unfortunately, The screen of my Razr M shattered. Neither screen, nor digitizer work, however, it is still alive, as is detected by pc.

I need the phone's internet tethering function and can't afford a new one, so decided to control it via pc. For it I need to enable usb debugging in order to use adb functions.

My phone is on 4.4.2. 183.46.10 bootloader.

I don't know if it is unlocked or not.

It is rooted (maybe).

 

As you can see, I could not enable usb debugging. Somewhere I read, that some recoveries have adb enabled, and from that I would pull changes to settings.

I tried to install one bootloader via fastboot, but here is the error:

 

C:\Windows\system32>fastboot flash recovery D:\TWRP2710-RAZR_M-KITKAT.img
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
sending 'recovery' (8866 KB)...
OKAY [  0.684s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.954s

 

what would you suggest in my situation? how to enable usb debugging? which recovery can I flash, that does not require unlocked bootloader?

 

Thanks

The ONLY recovery on a locked bootloader is stock recovery and normally only for the system you are on.

Thanks. Pretty bad news although.

 

Does stock recovery have usb debugging on? How to enter stock recovery via fastboot commands? As I know, the current bootloader can't be unlocked, right?

The kk bootloader can be unlocked but you need adb working at least so your still stuck
