Jose still hasn't gotten the Android 5 Lollipop update. How can he force the update? Leo says to head on over to XDA-Developers.com and look in the forums for how to root his specific phone. He should look for the model number of it. Once he's rooted it, he can replace the recovery software (ROM) with a custom one like Clockwork mod.
Once that's done, he can upgrade his OS to Lollipop, likely through Cyanogen Mod 12. Jose should understand that there is a risk of bricking the device. If he follows the instructions exactly and carefully, he should be successful.
