Sadly to say, but seems like mfastboot is outdated for now. I get error trying to flash SU6-7.7 ROM for Droid Maxx. RSD Lite 6.2.4 is ok.

LOL. I found the cause. Being Moto enthusiast I'm using mfastboot of latest version renamed to "fastboot.exe" for very long time, but recently copied foreign file and mixed up with mine, so that was the cause

Thanks for the hint!

Change the file extension for system_signed so it's
system_signed.img

I followed the instructions to a T. Now I am met with the red boot light of death. The phone boots, gets past the moto logo, then does the "Drooooiiiidddd" boot sound and has the loading red eye. Then. . .gets stuck. I used a batch file containing the following

Quote:

mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash recovery recovery.img
mfastboot flash system system.img_sparsechunk.0
mfastboot flash system system.img_sparsechunk.1
mfastboot flash system system.img_sparsechunk.2
mfastboot flash system system.img_sparsechunk.3
mfastboot flash system system.img_sparsechunk.4
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
pause

Is there anything I should try? I am on Windows 10, so the RSD method does not work for me. I am using the 1080 Verizon version. 16gb. When I originally flashed it gave me an error about gpt.bin.
