INSTRUCTIONS:
For zippers that can be flashed, download the zip file for the Android version you want and place it on the Micro SD Card. No, USB OTG will not work because the tablet is visible in the "/ mnt / sdcard" directory and there is no OTG capability there.
Change tablet and insert SD card.
Boot into recovery by holding the power button and the volume up. In recovery, use the volume button to select and the power button to confirm. Select "wipe data / factory reset" and press the power button and wait. This may take time.
When finished, select the "clear cache" option, pay attention, your tablet might reboot or do a few other things, just ignore whatever it does and continue.
Now, just press update through external storage and select the zip file and press the power button. Make sure you don't rename the zip file, otherwise you will get a signature verification error. Wait for it to finish and then delete the data / factory reset again and reboot into the system!
