There's no particular link dedicated to your issue that's why you have to search, read and...
All you said has been talked about in the forums.
Maybe the time spent experimenting & typing all this would have been better spent on searching and reading.
I guess experience is really the best teacher for some people. ;)
TWRP is irrelevant in the current ROM installation because it is done through fastboot using a PC or Mac.
The steps to do this is in the first post (Installation of A12 devices via Fastboot)
Or second post (second red paragraph)
Let me also jump the gun.
See you on the other side ;)
N.B: updater crashing isn't such a big deal...right?
Maybe clearing data of updater app will help
You were told exactly what to do
What further help do u need?
Make sure to enable "show all apps" from top right menu.
Then search for Google play services
That is the normal and expected behavior. This is done to prevent "tapjacking"
I doubt there's anything to fix.
Disable draw over other apps for the app Or quit the app
