Hello,I am looking for the latest firmware for my Allwinner T3 K2001M Android 7.0 device, but I can only update using the upgrade.zip method. If you have a current firmware file that I can update with this method, I would be very grateful if you could send it to me.Also, every time the device is turned off and on, the date and time reset to 2017. I would appreciate your help regarding this as well.Spoiler: Screenshots
