when ooma is in the process of updating firmware maybe it would be possible to have a unique sequence of flashes similar to that of when the telo boots up (lower right set of buttons flash in sequence) that is recognizable so consumers know not to interrupt the process-- maybe even a pre-recorded msg telling you this is happening when you pick up the handset (instead of the fast busy signal).

** also, a text msg alert to say Telo firmware update is (about to be) in progress (at least 1 min before it begins).

The upgrade process suspends itself when you make or answer a call. You can also safely unplug the unit during an upgrade because it will resume when the unit is plugged back in. Also see viewtopic.php?f=6&t=15471

So long as you don't unplug it at the worst possible time (during a flash of the rom, not downloading the data). Supposedly, this accounts for an unknown amount of telos being bricked.

Unplugging during a flash of the file system will not brick the telo. Only exception to that is when the boot loader is upgraded, which is a rare occurrence and takes less than 10 sec so the window is very small.

Bricked boxes during a mass upgrade typically result from unrecoverable flash errors. A unit with such errors will appear to be functioning normally (calls will work) but the flash will not except any changes (e.g. a phone number change). The percentage of boxes impacted this way is very small and keeps getting smaller because of improvements in flash operating and recovery systems.
