[Octopus box]

Most likely, your device has HW problems. Anyway, we will try to prepare new test Software version and contact You. This will occupy several days.

[Alva]

the same error
The phone only detects by pc after wrong flash
I use 1.6.8 LG software

[Octopus box]

What is the state of your device exactly?

[Alva]

nothing on the screen
Just deteced by the PC

[Octopus box]

Your device doesn't answer to Software's CMDs, most likely, this is HW issue.
