I posted this on another site but this appears to be a better site for a possible solution.
I quickly removed the battery, rebooted, but then every minute or so it would power down to apply the update.
Within one of those minutes I quickly deleted the update file from the cache folder using root explorer. Now when it rebooted, it did not try to load the update, I could see my stuff but... still re-booted every minute or so. I guess this was probably not a good idea.
Long story short I tried a lot of stuff, wiping cache, resetting to factory, using rsd lite to try and flash it with both ICS then JB but kept getting errors such as "Signature not valid" or cdt.bin errors or
"Error in tmp/sideload/pkg.zip
Tmp/bp.img
Status 7 installation aborted."
Anyway...
Eventually with deleting the lines <oem-fb-mode> from the extracted JB xml file I was able to load JB using rsd-lite and it seemed to make it through without errors. I can get to theWelcome screen for set-up but damn -within a minute.. still reboots. So I think (not positive) JB is properly loaded but it is still re-booting. I also tried loading the same xml.zip files from the sd card. "
Any ideas how to stop the rebooting?
TIA,
