First I rooted my Droid as per: Motorola Droid: Full Update Guide - CyanogenMod Wiki
Got the ROM Manager installed and working and then selected: Peter Alfonso's Stock Rooted Gingerbread ROM GPA 13 using the ROM manager, but didn't install the kernel!
Rebooted phone and it shows a M logo, blinks and gets brighter, but nothing from there.
Tried to repeat the rooting steps to reinstall the update.zip and got errors: e: update.zip install blocked and E;error in /sdcard/update.zip (Status 7) installation aborted.
Got a fresh sd card, loaded update.zip on it and repeated rooting instructions with the sbf flash. Got the update.zip to load by first selecting allow update.zip. Loaded update.zip and got message that it was successful, but still boots to M and hangs.
I would really appreciate your assistance in returning to an operating phone!
