How do I get my launcher3 to respond?

[AC Question]

My Droid restarted after some updates and now it continuously locks up with the message "Launcher3 isn't responding. Do you want to close it?". No matter the response, the phone locks up. How do I fixe this?

Go to the Play store with another computer. Log in with the same account the phone is connected to. Install a different launcher. The next time you start the phone you'll be asked which launcher you want to use - select the new one.

(If it still locks up, the ROM is corrupted, and you have to reflash it. Warning - you'll lose anything that's not already backed up.)

Is it possible to back up before re-flashing? I downloaded Nova Launcher, still locking up!
