What one you chucking on Jay? XXDLJ4?
yeah, flashed over the polish rom fine, everything seems fine. I must admit the Samsung way of flashing roms (ODIN) did concern me as it's totally different from what I'm used to with HTC (RUU's) - but it's so much quicker, doesn't care what HBOOT you're on.
Oh Chainfire has a Mobile Odin app in Play store too, so you won't need a PC to flash a stock rom (you can still use CWM for 3rd party roms).
Rom toolbox pro is pretty awesome, check it out.
