[Sony Tablet S] dknw:
Aha, glad (not really) that I wasn't the only one that wishing to make XTS more like XTZ got stuck on animation boot. I wiped the data and nothing happened, still stuck. I can enter recovery and the my PC recognizes ADB when I'm in recovery mode but I can't initiate adb shell. Here is my recovery log.

Starting recovery on Fri May 10 00:23:37 2013

can't open /dev/tty0: No such file or directory

framebuffer: fd 3 (1280 x 800)
