Does anyone have experimented this issue? I came from 2.0.1101. I've tryed to install 1129 from SD. It was successful. Reboot the tablet. Change language. Trying new screenshot function got an error... After a while I discovered it can't read SD card. Try reformatting by w7 without success. Going Settings -> Memory app crash (only app not SO). Going back to 1101 SD goes without problem. I've read a suggestion in another forum. Use SDformatter but I've not yet tested. Cantastorie.
