[andu]

here You go (Camiloml suggestion to use Recovery) :

*******************************************************************************************

Do this.

Rename the ROM file to PIWG1.bin and place it on root of FAT32 formatted pendrive.
And flash it by recovery holding FN-B with pendrive inserted and while you press power on on laptop
(from powered off state)

From another G770 user

1. turn off the laptop
2. Unplug the power cord.
3. insert the flash drive
4. press and hold Fn-B key combination
5. while holding Fn-B, plug in the power cord
6. still holding Fn-B, press Power button
the computer will spin up the fan but the screen will remain black.
If it finds the appropriate file, it'll beep again, read it in, and will start flashing the BIOS.
Once it's completed flashing the BIOS, it will continuously beep, the power button will not respond,
neither will any key combinations (Scared me at this point, thought i bricked my motherboard).
I unplugged the laptop from the power, pulled the battery to kill the laptop.
Once I put the battery back in, I hit the power button and it powered up and ran without issue.

So this way is tested and wroked, i hope It will work for You but I know that
NVRAM is emulated into Firmware Eeprom Chip so It will remains like DMI data !
If You will not Recover your laptop then only way is rewrite manually by SPI PGM
the Pure Firmware without the wrong Video Settings !

I said I already tried that but it doesn't find my PIWG1.bin

To use spi pgrm... how to locate the bios chip?

Regards!
