LG Vu 920 error

Fatal error, means almost the same as it died.
If you can't reset it, I think you have to bring it to a LG certified repair centre. Or start saving for a new phone?

1. remove the battery and power cable 2. remove the sim and memory card 3. reinstall eveything 4. estart your system

Seems like the ROM of your mobile got damaged where the phones operating system is. I'd say it's a goner.
