[Android Q&A, Help & Troubleshooting] tajha:
Hi,

I have a problem with LG L65 (D280n) and I hope someone here could help me. Suddenly my phone stopped launching. A few days ago I had an OTA update.

I tried almost any method to unbrick I found on Internet but I still can't launch it.

Symptoms:

-> black screen, no vibration, no sound, no logo when turning the phone on,

-> connected to USB shows as: Qualcomm HS-USB QDLoader 9008

I was searching for solution to 9008 mode and I found solution on russian forum: method with loader written on micro sd card. When I inserted sdcard and rebooted phone:

-> phone launches, vibrates and shows: Demigod Crash Handler: DBI Fatal Error, Pink screen,

-> connected to USB shows as: LGE AndroidNet USB Serial Port and Qualcomm MMC Storage USB Device

What I tried:

1) LG Flash Tool 2014 -> Stops at 4%. Log attached. It looks like it cannot comunicate with phone,

2) Write something on Qualcomm Storage, which shows as unformatted (RAW) partition. Windows says it can't finish formatting,

3) Extracted files from kdz, and tried to write PrimaryGPT_0.bin using DMDE. Write ends with success but I don't see any data changed on the disk. It is filled with zeros. Only last few sectors have some data written.

Cant get into Download Mode, always have ping screen even with Volume+ and Power buttons hold.

What I can do now? Are there some other tools which can communicate with my phone by serial port or something?

Is there any magician which could unbrick my phone? :D
