How to reset to factory settings in the recovery menu if I can't choose any option? (Android- Lenovo A390t)?

I tried to reset my phone to factory settings, and after I hit in the reset option from settings, it rebooted and then it says "android upgrading" starting application. And it's going like this forever.
I tried to enter recovery mode but I can't choose any options, like wipe data/reset settings.
What can I do? My phone won't start, and won't boot after the "android upgrading" sign.
My phone is not rooted.
I have a Lenovo A390t from China! I bought it on nov 2013.
