[G4 Q&A, Help & Troubleshooting] Rich Rich:
Hi People,

I think I've hard bricked my G4 (H815 International TWN model)

I made a mistake flashing with TWRP after following [MENTION=5545101]steadfasterX[/MENTION] brilliant H815 unlock guide. The unlock worked perfectly but I was trying different custom ROMs ended up bricking the phone by flashing a boot image in TWRP.

It is completely dead, no fastboot, no download mode, only black screen. The phone does vibrate when holding power button after inserting battery but nothing happens no USB device when plugged in.

I followed a guide for using QFil to flash my phone. I shorted the test pins and it booted in 9008, I used SteadfasterX's H815 recovery files from another thread (https://xdaforums.com/g4/general/guide-proper-h815-unbrick-qfil-files-t3709212) and flashed device, all goes well and the flash completes, albeit after 3.20min. But once this is done and the phone is restarted I still end up in the same position of no download or fast boot, exactly the same.

Is this a true dead phone or am I doing something wrong in Qfil?

My QFIL log is here:
