Hello TechKnow members and visitors!
Sometimes your device can not boot anymore. It will be stuck on the Android logo for eternity.
You can fix this yourself probably thanks to the recovery mode!
Entering the recovery mode:
It's something like holding volume up button while turning it on (or the volume down button)
If all went well, you will see a picture of an Android (probably with a exclamation mark)
Navigating the recovery mode:
Then use the plus/min volume buttons to scroll through the recovery options. The power button (on my phone) acts as the enter key.
I hope this saves your tablet!
