fastboot - I am getting an unknown file transfer error (Flashing TWRP)

I am trying to flash twrp onto my unlocked Moto G4 Play so I can install a new version of Android but, I keep on getting this error. I have recently factory reset my phone and I am not sure if it is related.

C:\adb>fastboot flash recovery twrp.img
target reported max download size of 268435456 bytes
sending 'recovery' (8296 KB)...
FAILED (data transfer failure (Unknown error))

finished. total time: 5.013s

Any suggestions?

Answer

The FAILED (data transfer failure (Unknown error)) error can happen for a few reason. It happens when there is issues with communication transferring data. To trouble shoot the cause start by:

• Trying different usb ports


• Trying different usb cables


• Update fastboot.exe


• Download another .img file and verify the md5.



• Double check the Bootloader is unlock
