Help Factory Reset Question

I have a Sprint Galaxy S2 which I recently upgraded to Jelly Bean 4.1.2. At first everything worked fine but today it started crashing the Settings screen when using Bluetooth. (Unfortunately, Settings has stopped working).

Since it was working after the upgrade, I would like to hard reset the phone and reinstall the Jelly Bean upgrade. My question is:

Can I upgrade directly from the reset phone to JB or do I have to go through intermediate steps by first upgrading to ICS?

Of course, if anyone out there knows how to fix this JB problem with Bluetooth, I certainly would rather do that than go through the full reset and reinstall route.

Thank you.
 
Once you've applied the update, you can't go back without flashing a completely new factory image. If you perform a factory reset, you will stay at JB 4.1.2.

Thank you for your response. I did the factory reset and when the phone rebooted, it opened with "Talkback" in operation and I don't see any way to stop it. I cannot swipe screens, or get past the first screen in Settings.

Well, I took my phone into the Sprint store and the tech there did a factory reset and it fixed the problem. Apparently they have a magic touch that I don't have.
Thanks for your help.
