XPR4550 old software safe?

[kb5udf]

Hi Gang,

I have a friend who is retired from the 2-way business. He has an XPR4550 and he has his old (properly licensed) CPS laying about.
He does not know what CPS last programmed the radio. Is there any harm in trying the CPS he has, or will it risk bricking the radio
if the CPS is too old (like I have heard that will happen to MCS2000) series.

Bottom line, any harm in trying to write to radio with old software, or will it just throw an error and refuse to write like most Moto CPS?

Thanks

Does it read the radio?

The MCS2k were odd ducks (however for some reason I love mine) , and newer radio/cps versions are much more tolerant of "codeplug too new" or other issues. You're likely to get an error message than a boat-anchor.

He did not attempt to read yet; he bricked an MCS2k before so wanted clarification first.

It's fine, it will either read the codeplug, or tell you it can't. You will not brick the radio.

If he bricked an MCS2000 by trying to read it, it probably wasn't because of the software version mismatches.

There's a LONG time between the software written for those two mentioned radio lines, and it's much improved.

He did not brick the mcs2k trying to read it, it was a write.

Kayn, thanks for the answer.

He could have bricked it if something happened to the data while the radio was writing. It's happened to me before and with older radios like that, I'm not surprised it happened to him either. Doesn't necessarily have to be a software problem.

You need MOTOTRBO CPS 16 Build 828
NOTHING ELSE WILL WORK.

And you know this how?

That's what I used on an XPR4550 MOTOTRBO DMR. That's the correct version, but yes I'm not sure if anything else would work.

NOTHING ELSE WILL WORK.

Depending on the firmware version of the radio there could be numerous versions older than 16 that would work.

If your firmware is too old, V16 B828 won't work. As long as the correct CPS version is used with the paired firmware, other versions will work.

I use CPS 13.5 to read/write to radios that were programmed in the past with 16.0. You can go back a bit, but not too much.
