I would pull the battery again and wait a good 30 minutes to see if it will boot up. Maybe it won't, but I had an experience one time where it took a long time after an OS reinstall. I know yours errored out. But worth a try. Then, if it doesn't boot up, do a wipe with JL_CMDR and install the OS. See:
