... search the forum next time, your running the beta 3.1? you should just be able to enter recovery mode and install the update if you do not get an ota update

so I installed beta on from here

Sorry, I first do it, or could you write more or show me ...

I renewed a 3.1 firmware in this manual
http://gtvhacker.com/index.php/HC3.1onRevue
but I see that already has an official update
Can I go to the official firmware?
may need to lower the firmware to 2.1 then update to 3.1 official?
help plz
