MAKE SURE TO HAVE ENOUGH FREE SPACE or update fails.
OTA process failed, I think I also had an out of space issue?
I/SystemUpdateOTA(16111): Copy file from /storage/emulated/0/update.zip to /data/data/com.dell.systemupdateota/update.zip
I/SystemUpdateOTA(16111): Fail to copy package to /data/data/com.dell.systemupdateota/update.zip
EDIT: OTA is 1GB and I only had 750MB free. Trying again.
EDIT2: Update successful on tablet that was rooted. Lost root though. First boot took maybe 10 minutes sitting at the "intel inside" screen.
Also, Developer Options now has an "OEM unlocking" option, but 'fastboot oem unlock' doesn't seem to work. Not sure if this is normal or a side-effect of having been rooted and/or having the developer firmware previously installed. I won't have much time today to mess with it but I can maybe upload the update.zip in a few hours.
