I have quite a few g4 beta units. Look like final betas. Anyone know how to program model numbers in to them so they will program with current PPS? There has to be a way. They work, they track, I can program a system and then FW upgrade to 1.33 and they work, I just can't edit or turn on TG hold/block because PPS says they're too old. Any ideas? I'd hate to just part them down when I can give them to family members to listen to. Not looking to resell but open to someone on here that is interested in tinkering. I wouldn't stand behind it as "reliable" and that's the only way I would sell a used unication unit.
