I started using RZR 2.0.3 in place of SPR a little while ago. Today I tried to flash a new ROM for the first time with it. After the update was complete, I rebooted into Android, but the phone was stuck at the 'M' logo. Restoring to the backup didn't help -- noticed that the backup doesn't contain a boot image.
Finally got my phone working again by flashing the sbf for stock froyo.
Any idea what I might have done wrong? I went from SPR to RZR by using the update.zip, which I read today might not be the best way. I like the features it has and I would really like to start using it.
