I have a MotoDroid1, was running Froyo1.whatever. The phone was rooted with EasyRoot and i used Barnacle Tether to provide Wifi for my iPad. last week received 2.2 update and lost that ability. last night I flashed SPRecovery and now the phone reboots every 15 seconds. I first flashed SPRecovery_ESE81.sbf which started the problem and the i tried flashing MC1_A855_1282081087_Recovery-Only_SPRecovery_0.99.3b.sbf which didn't seem to change anything. Not sure what to do next.
It,s only reebooting when it is plugged in to a usb or charger, otherwise it just shuts down.
