Hi, this is interesting work, I'll be your next tester if you like...
Also take a look at ReactOS project that has been developed for both ARM and x86, I'm struggling to run it on my tab(P7500)...
It has never been a problem to run P7510 ROMs on P7500, so don't be afraid to test all the things you get for the TABs
Thanks again for trying to bring new life(new OS I mean) in the SGT forums...
