[Q] D855 Seems to be bricked? topic

Hi All,

This is my first post here - I hope this is the correct section.

My phone is totally standard and unmodified.

Last week my phone downloaded an OTA update, this installed fine and the phone worked for a few hours after, then whilst typing a SMS the phone seemed to crash and power off. It now doesn't respond to any of the buttons, won't enter recovery mode etc.

Things I've tried:
Battery out for extended time, back in - nothing
Plug into power - nothing
Plug into PC (windows 8.1) with battery in the phone - windows reports device not enabled/possibly malfunctioned.
Power + volume down - nothing
Hold volume while plugging into usb - nothing
Plug into PC without battery - phone appears as "Qualcomm HS-USB QDLoader 9008" in the COM section on device manager.

I've attempted guides on various posts on this forum; when using this post: (http://forum.xda-developers.com/lg-g...s-usb-t2933853) I managed to access the files on the device, but was unable to re-write the stock files. I got an error for phone not in download mode.

I've also tried accessing via adb and fastboot; adb devices does show the device (with battery not in phone) but when i try adb reboot bootloader nothing happens and the phone disapears from adb devices.

Fastboot does not find the phone.

I'm wondering if it could possibly be a battery fault? Would the phone boot up while connected to power but no battery?

Any help very much apreciated!
