My Bionic was rooted so I never accepted the last update back about 7 months ago but that message kept comming up to update and I accidentally hit accept the other day. 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. rebooted, and it did not try to load the update, I can see my stuff but... still re-boots every minute or so. 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 the screen for set-up but damn -within a minute.. still reboots. So I think (not positive) JB is loaded but it is still re-booting. I also tried loading the same xml.zip files from the sd card. But still no luck. Anyone have any ideas?
