Unication pager revert to older codeplug?

[ttiiggy]

I have Unication Alpha Legend+ pagers and programming cradles.

I was working on two pagers for now. I tried using PPS to write new programming into a pager and it said it won't work.
I read the other pager and noticed that they have different codeplug number designators.
One pager shows codeplug R08.02.09. One pager shows codeplug R08.03.01.

I looked around and found that the computers have different versions of PPS.
Most computers have PPS version R08.02.09.
Apparently a newer computer got PPS version R08.03.01 installed on it and this pager got programmed with it.

I got this pager programmed. I noticed that I had a typo in the name and got interrupted. I got back and placed a pager in the programming cradle and programmed in the correct info. Discovered that I had programmed the other pager with the newer PPS. Now I have TWO pagers with the newer codeplug.
It looks like the pager codeplug version is the same as the last version of PPS that it was programmed with.

I don't want to change the PPS in the other computers. I wanted to just change the PPS in this one.

I would like all the pagers to have the older codeplug in them so that they can be programmed with the older computer.

Is there a way to go BACK to the older codeplug?
