Hi all!
I just kill one GP300 (UHF model) - when I tried to read radio, SW said that a codeplug is corrupted. I upload into radio a codeplug from other GP300 (saved to disk before) - and the radio blinks by yellow colored led and no transmitt, no receive... Now codeplug can be readed 100% without errors. How can I revive this radio?
Thanks,
please REPLY TO EMAIL: [email protected]

HI:

Well, you may be another victum of a Code
plug corruption.

If you let us know what kind of programming
platform you are using, and the speed of the
computer, chances are I might be able to
help.

The problem is that you should be using a
386-486-25 Series Computer, Factory Rib box,
and preferably a Factory Cable.

If your radio will not Read/Write anylonger
with the above set up, chances are pretty
high a ~//~ Service Tech will have to fix
it...I am addressing another issue on a Saber
on this board at this time.

If you are not able to find someone in your
area, please feel free to contact me direct

Monty-

I'm sort of in the same boat with a '97 8-channel P110 I was trying to convert to a GP300. The RSS appears to be writing the codeplug (no errors during the write process), but on read it says the plug is corrupt, and the model number displayed is mostly blank with some garbage characters. The radio powers on with the "hi-low" tone.

Is there anything I can do to resurrect it? I also have a similar vintage (different ROM version however) 2-channel P110 - could I make 1 good 8/16 channel GP300 out of them?

What method were you trying to use to convert this radio. I had one codeplug that went screwy with Toolkit. I cloned the original codeplug back to the radio on a stable platform and the radio worked fine after that. The problem I had was a unstable computer, hard disk trouble. The radio had no TX or RX, but after loading the original codeplug back into the radio, no trouble. Pays to keep a backup. Just my 2 cents.

The radio was too new for my RSS (and TK), so I never was able to read it and make an archive. Instead, I read another radio and tried to write that codeplug to it. (I know - it was an obvious gamble and I lost).

I can't understand why writing another codeplug to the radio won't resolve the problem. Why does having a corrupt codeplug in it prevent a good one from "taking"? I'd think the read/write process would be handled by the PROMs, and the codeplug would just be data that could be overwritten.

I did manage to find a copy of the Lab "GP Utility" that lets you diddle the bits of the code plug, but it's VERY old, and barely runs at all on my Pentium 100 slowed to 1% via MoSlo, and won't communicate at all. (I've got a slow 386 on the way, so it may work yet.)

:sad:((((((((((((

I used AMD Athlon 900 on VIA KT133 mainboard, boot from MS-DOS 6.22 and the software was patched GP-300 SW.

The problem is that you should be using a
386-486-25 Series Computer,

I programmed at least 10 SP-300's and ALL was fine...

Factory Rib box,

I haven't it, I just used Nokia GSM phones M2BUS interface - as usually, works fine with all others GP300/ GM350.

high a ~//~ Service Tech will have to fix

It going to read/write 100% OK , I can read all the data I wrote to radio before, but... it just blinks by yellow led and doesn't works :sad:

Well, I somehow managed to resurrect my dead P110.

I got an old 386 laptop, and played around with a modified RSS ("GP300IVG" it was called), along with an ancient Moto "GP Utility" tool.

I read and wrote it several times, and also did a couple of "Part write code plug" with the Utility (whatever that means), and it suddenly stopped doing the beep-boop on powerup, and returned to the normal "beep".

As it stands now, it appears to have a combination of two code plugs in it. The serial number and mode data is from another 16 channel radio (a P110 converted into a GP300) that I originally tried to force-feed it, but the model number is "1B 1C" hex (where a GP300 would be "03 14"). Not sure what model this would actually indicate, presumably it's the original P110 8-channel model it started with.

I tried modifying the model number in the code plug and correcting the check sum, but every time I wrote a code plug with a different model, the error sound returned. My guess is that the later ROM version "knows" what model it should be, and rejects changes. Hoffis implies this in his second doc.

The net result is I basically accomplished what I wanted, ie, an 8 to 16 channel conversion, and locating an RSS version that can program it. I don't have a "normal" RSS that supports this new a P110 (1997) to try it with, though I suspect it might not be programmable without using the modified "IVG" RSS.

I'll probably correct the model number. re-write the code plug, and quit while I'm ahead.
