If you flash the right firmware it’ll work.
Something I missed! Mine wouldn’t enter programming mode. It wasn’t clear that you need to have the front cover up, and ALSO slide the back cover out a bit as well! There’s a sensor there that has to be open. 😁
Then it went right into programming mode as in the video. Manually print a ticket just to see current firmware. Unplug power & connect the serial cable on top. Lift the front lid, and slide the back out just a bit. About an inch. And you can put it in programming mode. And do a comm test with the flash app. If it fails, check com port and port speed on your PC.
But once you get a good response you can flash it. It will indicate it completed.
If it doesn’t print a ticket right when done. Just unplug everything. Close the lid and slide the back in. Then do a ticket print by pressing down the feed button and plugging in power. Then it will and you’ll see the new firmware listed as compared to the test ticket printed before flashing it.
You know it’s good if it changed. And you can put it back in the machine.
I had a USB/Netplex model that wasn’t for IGT AVP.. But once flashed I could just plug in USB & power without mounting it. Powered on my AVP. No errors and I could do a test print from the AVP diagnostic menu. So I knew it was good to go. 👍
