PM1500 FW Upgrade Problem
Posted: Wed Jun 29, 2016 5:57 am
Greetings. I have a PM1500 VHF from 2006 with original drawer, head, and accessories that simply will not take a firmware upgrade. We're trying to make it a dual head setup, and very early FW versions of this radio didn't support that, if I remember correctly. I have spent 24 hours trying every permutation of serial, USB, a second control head, control head port programming, drawer programming, numerous FW R20.xx.xx versions, etc. and have come up empty. I'm using CPS 20.01.00. I get to step 12 of 20 (starting hardware flash) and error out after a few minutes with retries doing nothing for me. Eventually, I cancel, closing the port and end up with a "a component's version was not readable" message at this point. The radio reads and writes fine for programming and I have no 'maintenance mode' or error codes at anytime.
From years of flash experience, I know a jump from R08 to R20 can make things challenging, but I don't any longer have any FWs in between to try to bridge with gap with a multi-upgrade step up from there to here (R08 to R12 to R16 to R20, for example).
I did see something on a Batlabs search that made a disparaging comment about R08.xx.xx FW. Is that my downfall? I'm hoping to avoid a depot trip for this unit. Any ideas or help available? Many thanks!
