[Q] How to unbrick my 4X - a question of life and death! topic






I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB. Ch
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)

I think it’s still locked.

This method hasn’t help either…

What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.

Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA elsewhere without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM. :rolleyes:
