on the following phone, on the following tablet. So first of all let me hold down power key for a few seconds, then choose power off and
0:18
tap ok to confirm it. Wait until your tablet will be completely switched off and afterwards you have to start
0:29
holding volume down. While holding volume down press power key and keep holding these two keys for a while
0:38
When the device vibrates release power key and keep holding volume down for a couple
0:43
of seconds. I'm still holding the volume down key

Release volume down as soon as factory kit test just pops up

2:02
time and from the following menu you can choose restart or power off
