Si tenim un telèfon VoIP AT-320 que volem fer-li una actualització del firmware però resulta que el paquet .bin que hi carreguem no està en bones condicions o si ens equivoquem de paquet, a mi m'ha passat que el .bin estava tocat, el telèfon sens queda sense un firm adequat per poder-hi connectar per xarxa.
A la pantalla apareix un missatge Booting... que no acaba d'engegar ...
No respon: ni la IP, ni res de res, et mires el telèfon i no hi ha botons de reset, ni coses semblants, ni manual. El telèfon és acabat de treure de la botiga, comença la fase de patiment 
Però tranquil que hi ha una faq interessant:
How to recover the phone if it crashed during upgrade?
Never set "debug"to "no check", because this way program won’t check if the firmware matches the hardware or not, which is very dangerous. If user really doesn’t know the hardware type, please send email to support@aredfox.com to get help. Once upgrade failed, follow the below steps to do safe-recovery:
1.Press and hold * while power up, until you see * begin to display on your LCD.
2.Power off and do 1 again, after the second time power up, our standard design IP phone's default IP address is 192.168.1.100. There are exceptions, like with Unisen ip8008, the default is 192.168.0.100, and with Vida iPH-E00 serial phones has default IP address of 192.168.1.10.
3.Put the ip phone and a Windows PC on the same LAN.
4.Run palmtool.exe on PC. You can try palmtool "Start Debug" button, a debug window will pop us, and if you press key on the IP phone, the key and the IP phone's IP address will be displayed on the debug window
5.If you PC's address is not 192.168.1.xxx (not on the same LAN of the IP phone), change its TCPIP settings to the same LAN.
6.Put 192.168.1.100 (or other default IP) in the palmtool "IP Address on Chip" field.
7.Find the correct upgrade file, and use palmtool "Update Program" button to update your IP phone.
