I have 258 MB data partition. I had to uninstall Jelly Bean because it bricked the tablet really bad and it took me a long time to unbrick it. It started working very slow and unresponsive, it wouldn't go past the first registration process where you setup your google account, the keyboard was stopping all the time. Android.process.acore was stopping all the time. I coulnd't go to settings to turn on debugging mode. Finally it started rebooting and then it got stuck in the android logo and would not boot. I managed to get it into fastboot mode by holding power and volume -.
In fastboot I tried to flash a backup from my pc, it flashed ok but it would not boot. Finally I could flash a recovery image and boot it from fastboot and it worked. From recovery I formatted the partitions and flashed ICS and gapps and now it is working fine, but every once in a while it asks me for the registration number. Anyway, thanks for your hard work.
