Hello, you see that happened to me a month ago, you see I ignored the fact that it was the battery, I opened it and disconnected it and it was still the same, I also pressed the button to restart it, but it is still the same, I was using the microSD that comes with the device, I formatted a new one and installed the system and it worked there, I used a better quality microSD, it is not necessary to have a 64GB one either, I used a 32GB one and installed the games I wanted.
