I always have problems with M7, this time cant flash


Hi there folks

Am having problems to flash m7 from verizon

I have downloaded both 4.4 and 5.0 firmwares from support, i put phones in RUU
renamed both filkes to PN07IMG.zip

when I try to flash I get errors

When I manually try to flash using fastboot flash zip PN07IMG.zip, it takes lomger, sending the file but finally also get errors.
I have set the phone to SuperCId and it is s-off, boot-loader is locked.

here some info

Code:
