So I'm trying to fix a customers Razr M and I'm thinking the os got screwed up somewhere. I tried factory resetting his phone thru the boot loader menu and now it will only boot to that mode. So I tried getting the stock OS rom and got the device into the fastboot menu. I downloaded all the latest drivers and tried the flash. Every time I get the error, failed flashing process 3/21 flash partition "gpt.bin" -> phone returned Fail. Is there a different rom that I should be trying? or is this phone beyond repair? Any suggestions would help out soooo much. Thanks guys!
