Was windering if there is any roms for.this or if it was posible to.use the optimus black roms since there prety much the same?
The simple answer: No and no.
The more elaborate answer: No, there are no roms yet because access to the bootloader hasn't been figured out yet. Even if it had, the Optimus Black roms would not work with it because the hardware differences, however slight, can be the difference between calling a correct memory address and turning your device into a paperweight.
Having a rom made for your exact hardware is very important.
Ok now for my next ? is there any devs working on the marquee?
