LG P778g black screen after charging. Only S/W Update Mode when fastbooted

Hello there. My girlfriend has a LG L9 P778g (which is actually a P768). She was charging her phone last night, left it there. After a couple of hours she picked it up and the phone was dead, black screen and wouldn't boot up (No LG LOGO, NOTHING, not even the backlight on the buttons).

I've flashed P768 ICS xloader and uboot with fastboot by Lelus. Then went into fastboot with option 1. Went into S/W Upgrade Mode, and my LG was recognized by the LG Support Tool (it shows up as Android: OMAP440 FastBoot USB Device in Device Manager and as LGP778g in LG Support Tool).

Process finished to 100% (around 90% screen went black). But nothing happens, i mean, the cellphone still won't turn on, just black screen. I SEE NO LG LOGO, NOTHING. I can only get into S/W Upgrade mode after fastbooting. (No fastboot image on screen neither).

Any hints?

Thanks!!

Regards, Alan
