my tablet screen is cracked and the touch screen is not working so I decide to try reset my tablet but now it is just showing “=> FASTBOOT MODE” on my tablet screen.
Hold power key and try either volume up or down for it least 30 second it will reset
Unfortunately you will have to completely drain power from it which can take days if fully charged ! Then charge to about 20% and use your power and vol + or - to factory reset it but that is for the 10” only hope this helps good luck Micky p
actually, you don’t have to waste 3 or 2 days waiting for the charge to run out. you can simply hold the power button for 30-40 seconds and then it will restart. glad to help!
