A guy was selling an APX7000, & it had no tags, & a 123ABC serial #. I asked why it had the ALT DEV ser #, & he accused me of trashing his for sale post. He claimed to be the original owner. When I replied by asking why else a radio had a 123ABC ser #, this was the answer he posted. Sounds fishy to me. If I was to buy the radio, I'd want the original ser # restored. Not my name.
It was a buyback, a dealer sold it to a private EMS service, client went under, dealer bought back. Since it came from him and was flashed using depot for me, let's just say that they it's against their dealer agreement and would be detrimental to their business. They know where their products are sent and he's overly paranoid. If you would like I can have him change the SN to your name...
Sounds strange to me.
