why not? Can. Take a tablet, connect wifi, check for updates. How to download the new version - do not install immediately, but rewrite the update from the ota folder
Thanks, I spread just in case
Turn off the power, throw
firmwareonto the card, insert it, hold down VolumeUp and Power, hold it to vibration and logo, release it - we are in recovery.
Navigation through the old recovery: VolumeDown - transition by points, VolumeUp - selection of an item. In the new one, which with the latest firmware, everything is standard (up-down and Power for choice).
Sequencing:
apply update from sdcard, here we select the firmware file.
wipe data / factory reset
reboot system now
After flashing, the tablet loads for a long time, about 10 minutes - this is normal.
