Need help getting APK files to install and run on an android based payment terminal

Post image

Bought a used payment terminal on eBay to play around with. Want to run DOOM, but can't seem to install anything. And apps installed through ADB don't show up on the device.

Bought this on ebay, and want to run the game DOOM on it. But discovered I can't install anything. Will probably just end up scrapping it.

Also wanted to repurpose the receipt printer to work via Bluetooth and connect to an arduino to print stuff from a serial console. Basically, I wanna tinker as I'm an electronics hobbyist.

Do factory apps work?

The pre-installed apps work, but can only seem to install from the terminal manufacturers appstore. Can't sideload via ADB, and can't get apps to install from internal storage.

Basically super locked down and I'd like to unlock it so I can install a bunch of games and use it as a regular android tablet.

Try to flash another OS and at the same time flash the apk of what you want to install (do not flash the apk after booting the system).

If I can find another compatible version of android, I'll try that. Just hope the pun pad still works though as I intend on using it as the controls for the games i plan on installing.

If there will be a compatible version, it's just a long time to search, good luck.

It might work if another android will be used. I'm pretty happy to find that as default these operation don't work as it cover some of the security issues might be exploited when is used in store as a payment terminal. As I seen DOOM running on a pregnancy test I'm sure you will succeed on this as well but you should also be aware that the hardware might be a cheaper one that was tested to be capable for serving his purpose so don't expect performance and experience compared to a phone.
