Two links to the ROM are up!
You have to flash it from CWM, and you additional need to flash a V30 baseband.
I'm uploading too a pack with patched V20S .bin, V30B_EUR .fls, Smartflash and LG USB drivers... I'll post the link ASAP.
I hope that you like it... I've worked A LOT on it, and it's the beggining.
