I am having major issues with this damn tablet. It's my friend's actually, and he wanted to install CM7, but we got stuck at flashing the ROM. I boot into CWM, wipe data, and choose the CM7 zip, it says "opening update," then "Installing update," and then it just up and reboots. Or, most of the time it just freezes at "opening update." Hell, it freezes while I'm navigating the menu half the time. I tried booting from the SD card to install CWM to the SD card this time, but it refuses to recognize it this time around, even after formatting and partitioning it and copying the files again. Apparently the SD card installation is the only way to fix this? ADB detects it but I don't know how to use that to fix this, as nothing I've read in that regard seems to work. I can't restore and I can't flash, so is this Nook Tablet screwed? Do I owe my friend a new one?
UPDATE: I was able to fix the partitions using a script loaded in adb shell, two errors, in fact, but that still didn't solve my problem, it seems. The ROM won't flash, but instead hangs at "Opening update package," still. It's not rebooting anymore, not yet. But I can't flash still. Help?
