Default APX 4000 Codeplug Update Failed

First a couple of housekeeping items/background:

The company I work for is an authorized RX-only user on a Phase 2 public safety simulcast site that is part of a statewide system.

The APX 4000 was purchased new from a local Motorola shop.

It was initially programmed by the shop with later programming performed (about 6 months ago) by one of the LE agencies authorized on the system.

Although I've been a ham for 30 years and am proficient in programming certain brands of commercial radios, neither I nor the company I work for have access to any M programming software, cables or keyloaders. We did nothing to the radio.

Sorry, but I wanted to get all that out of the way to avoid unnecessary debate.

A coworker had the radio on his desk and says it was functioning normally. But, a little while later, noticed it was unusually quiet. He looked at the radio and the light on the front/top was flashing red and the display read "codeplug updt failed."

It's now quiet like a brick.

I did the usual power cycling and letting it sit without the battery installed. No joy.

I called the local comm center director and he advised that there were no OTAR/OTAP updates pushed and that our radio had not been stunned.

I took it to the Motorola shop, they looked at it for 10 seconds and, after asking me if I'd tried to hack it, they advised that it needed to go to depot.

My questions are:

Does it really need a four-week vacation at the depot?

Or, if the LE agency that last touched our radio had saved the personality and code plug (I think they did), could they re-upload those into the radio and clear the error?

And, the big one for me..... How the heck could this have even happened? Has anyone seen this before?

Although anything is possible, I've never seen an APX spontaneously display codeplug update failed.

My money is on someone monkeyed with it.

As far as the original codeplug being able to fix it we don't know since we don't know what exactly is wrong with it, but it's worth a try.
Someone told me signatures are silly, so I got rid of mine.

Try to rewrite the plug to it. May take a few times but if it doesn't then the depot is its final destination.

Giving the update failed and several entities having systems on it it's possible one did try a over air update or someone yanked the usb in process of writing or turned it off or the battery died during a write not allowing it to update the plug and reboot properly.

No telling. It has the odd issue the latest firmware does if someone tools around with older illegal items on loose out there. So from what I have heard and you describe. Newer firmware is finicky with the older garage stuff. Probably why he asked if anyone tried to alter it by that or at least read or write and something happened during the codeplug read and write process.

Try to throw in the saved plug, like I said may take a few times but if it still fails to boot depot is its trip.
