This doesn't look like an official firmware to me, is it ?

Cheers.

I don't think it is.Looks like a custom of the official V2.0.

Brush: If you use the OTA upgrade program updates, guaranteed to be the official Recovery If you are using third-party Recovery, please enter the recovery upgrade, otherwise it will cause infinite loop in the boot animation. The upgrade will format the data partition, your own backup. The built-in card, you can create a preinstall directory, you need to install the program on the inside, the boot can be automatically installed for the first time.
