Okay, so my update went horribly awry.....
I SBF'd, went back to Froyo, no problem. DL'd the update, seemingly no issue. Installed update, stock recovery seemed to work fine. After the reboot I got the bright and Shiny new Red Moto logo.....
Then Bootloader screen with following errors:
D2.37
Err:A5,69,35,00,27
Battery OK OK to Program Connect USB Data Cable
???
If you can't reboot to get running, you might have to go back to the Froyo SBF and start over..
