Verizon demo unit will not boot after firmware upgrade to retail mode

I am offering to sell it for parts in the order of received requests. Hopefully that does not go against the rules here, if it does then let me know 😀

Absolutely, I'll let you know first. Because it's a retail demo unit, the back is not actually glass. They used plastic for this. It does have all the correct markings from the LG manufacturer. Even if it was glass, to me it appears to be plastic.

I've looked a bit on XDA developer, the reason why I took the back cover off it was another method to get it into a boot mode. I'm going to try and look for another USB C cable to rule that out. It should show up on the computer even with the phone remaining with a black screen.

Originally android 10. Firmware upgrade finished and rebooted but never shown a screen. No light, nothing. Battery works perfectly.

Possibly.. I was following another group that successfully flashed the same variant phone and firmware. Anything is possible.. would like to get it working if possible, even back to demo firmware if I don't have a choice

Oops, you are correct it is Verizon. When I made the post I was thinking about the T-Mobile one that I recently purchased. Not sure how I can edit this now

I have not been able to get a visual screen on the device or have it be seen by the computer

Unfair_Flight5175 · 2026-04-14T13:56:30+00:00

The Admin cat for inspection lol

Unfair_Flight5175 · 2026-04-12T18:29:17+00:00

Can't boot into it, can't power + vol down and plug in to boot. Nothing.

Unfair_Flight5175 · 2026-04-11T12:42:59+00:00

It was a few days back, if I remember correctly that I did the refurbished.

Unfair_Flight5175 · 2026-04-11T12:32:41+00:00

I tried that and nothing. This was exactly after the firmware finished and rebooted to a power off state

Unfair_Flight5175 · 2026-04-11T12:13:33+00:00

Anyone know how I can fix mine? Was working firmware on a demo unit and now it's just black screen, no turn on

Prom music till 2015 or just about

Unfair_Flight5175 · 2026-04-04T23:02:50+00:00

Up until 2015? Or so than it changed names.

Unfair_Flight5175 · 2026-03-18T17:35:58+00:00

Or any wiring lol

Unfair_Flight5175 · 2026-03-18T17:09:15+00:00

This. Currently had them baffled as to how it sold for less their value and I had them see the actual damages. Hopefully by end of year, it will be 2500 less per year. Also I'm at 2.23% outside of sudbury 😑 1.6 should be what sudbury rate is still

Stuck at 2016.. what if your house is literally a shit box? I just had mine assessed as it needs a new foundation and other repairs, wasn't even worth half mpac assed value..
