thats not much help. There must be a way to trouble shoot the radios problem
What folks are saying (and your radio's symptoms indicate) is that the radio was either stolen, cloned, or used on a system where it wasn't supposed to be. The system console operator sent a remote command to the radio to shut it down so it could no longer be used. This command can only be reset by the system that issued the command (although you might get it reset by Motorola using some special software, and they will ask very pointed questions on how the radio got into that state) or if you have saved the radio's "S-Record" prior to it receiving the command there's a chance you might be able to use it to recover the radio.
This command is designed to help make a stolen radio worthless (since it can't be used and recovery very difficult at best unless the radio is returned to the system it was stolen from). It is also used to kill unauthorized radios that show up on a system.
You may want to check the radio's serial number with this database (
Global Stolen Radio Database) to see if it has been reported as stolen. If it's listed, you may be able to use that information to help persue who you got the radio from through the PD.
