Manually Performing Recovery Operations
Besides manual recovery options, the Android phones also feature an independent,
automatic problem detection and recovery attempt capability that can culminate in
recovery mode or in switching image slots. Android phones also feature a ‘hardware
watchdog’. This feature resets the phone if Android is stacked and doesn’t respond
(though Android stacking is unlikely); there’s no recovery process; the phone is only
reset.
All AudioCodes devices have a reset key or a combination of keys on the keypad to reset it.
While a device is powering up, you can perform recovery operations by using a two-
key combination.
When using a two-key combination, the device’s main LED changes color after every
n
seconds; each color is aligned with a recovery operation option.
