I was reading this thread and thought perhaps someone out there may be able to help me solve a mystery. Currently I have on my bench, an MTS 2000 Model III 800MHz portable. Model Number H01UCH6PW1BN Serial number XXXAVJXXXX, so it was manufactured in May 1995. I always thought that all MTS2000's were flash upgradeable. When the radio's flashcode was accessed with a SRIB, nothing would be read. The operation would crap out after the radio was turned off, and then turned back on. When I placed the radio in service mode, it showed a version of V05.43, the model and the serial number, but no flash code. Also, according to CPS, it has system package H37 and unknown firmware.
The radio operates on any Motorola Type I, II or IIi system just fine. The radio has no history of operational or otherwise problem.
Anyone know why this is?
