and the code for this is asterisk pound 2683662 pound. And here we've got the service mode
0:27
If you tap on more icon, you'll be able to reach some further options, further details
0:33
So let me go back. That would be all for this first one, the longest one

Now we will open the firmware version and this is the classic one and the code for it
0:41
is pretty easy because it's asterisk pound 1234 pound. And here we've got the firmware version

1:25

2:16
Then click on green to see if green is also good, blue as well
2:21
