Polycom vvx 1500 - error application is not present

Hello, I hope this formum help me!


Today I received a dead VVX1500 videophone.


It died by the following:


 - Someone tried to upgrade using the Technical Bulletin 53522.

 - The videophone tried to download the files from the FTP server, but shows this message: "BootBlock failed to flash all times"

 - I received the VVX with the issue. Checking the about page I discovered that it has the bootROM 4.3.0.


I think that it fails because the 'Upgrade' was done with an earlier version of SIP and bootROM. 


I have read some FAQ. And I have some questions:


If my phone is in a Reboot Loop, how can I check this info "Before you can successfully install UC Software 4.x.x onto phones running Polycom® UCS released prior to version 4.0.0, you must perform a required upgrade procedure using the Polycom® Upgrader 4.0.0 Utility."? I don't know what version it had before the upgrade.


Reload the software will recover the phone?


I will preciate any help, or comment.



Quedo atento a sus comentarios.
Muchas gracias.
