Hi, fastboot mode engineer here. Did u try resetting ur device (reset button on the backside of the tablet)
Thanks!
It's needed 2 times to type fastboot continue but it worked!
Thank u.. my mobile also had the same issue.. I hold the power button more than 10 second and then phone gets automatically reboot..
A better way to don't remove battery :
Android Multi Tools v1.02b
- connect phone / tablet to PC run program then press 9 . Exit Fastboot Mode
Good Luck!
1.Download adb fastboot
2. Connect the device to pc
3. Open Terminal in adb folder
4. type: fastboot devices
5. if you find your device type fastboot reboot
