Please help me find custom firmware or solution. My device turns off every 5-10 min while watching something on Kodi. Also when I try to download something from google store it automatically shuts down and reboot, and than again, the same download starts and device keeps rebooting. Only when I turn off wifi the device starts to work. I tried different power socket and changing wifi channels and everything. I also tried to find new custom firmware or software but without success, I think this is the newest for my device.
What do I need to do? Flash device with older firmware with batch tool?
I'm new member so xda doesen't allow me to post links so I made this one without prefix
