DM showed "upgrade available" for OS 7 so i attempted to upgrade. device showed error 507 and now won't go away. i'm unable to use the device nor can i connect to DM.
crackberry forums suggest various remedies from wiping device to downgrading OS. how can i do all this if my device is unable to connect to the DM? what happens to all the data on the device? can somebody help pls?
