So i use from HP download site old util, because this one for this model don`t have option for backup file. Only update bios and create butable usb. But i think for the half, problem coming from last attempt to update the bios. when instalation finish under windows, to be completed continue after restart. But then coming the problem. I see only error message for ENDPOINT problem, and auto restart, and again error message and next restart to infinity. After remove power and battery and cmos battery, i see only endpoint error and windows load normal. If that what you attach for me is correct BIN...

Hi can someone help me with my laptop please? I read and try over one week all posts here but nothing. I tried with the script to fix the backup bin file but just some error in Line 11 Error code 1. Elitebook 840G G6

And some idea for util to put back the fixed bios.
Thanks in advance!...
