[Weserx]

Well, my friend asked to me about this.
He was flashing this G4 plus, the process was done with success but it don't reboot the device, it just shutdown itself and the LED light turns on. after a check on the board it wasn't damaged or something like.
OS version: 7.0

What stock ROM were they flashing, what commands to flash? Does the computer still recognise the device when connected?

Are you able to boot to the bootloader?

What stock ROM were they flashing.
-it was the 6.0.1 as he said that it wasn't modified before.

what commands to flash?
-Well he used some kind of program that does it automatically maybe? i don't think that he has some kind of knowledge about commands lines, i am not an exception.

Does the computer still recognise the device when connected?
-Yes, he tried many times but the same kept happening.

Are you able to boot to the bootloader?
-I think yes, maybe, i'll get the phone in my hands tomorrow so i'll made a video to try to make it more easier for all us.

The 6.0.1 stock ROM is really old and generally only advisable to flash if you know what you're doing and that you're flashing the correct build of the firmware for your device/region. Do you know if your friend was flashing the firmware over a newer firmware build, and what build version was it? What program did they use (e.g. RSDlite)?

What does the device present as in device manager? Is it coming up as Qualcomm HS-USB 9008 or similar?
