LG Optimus 9.....error message process com.android phone has stopped.

[AC Question]

.....Suddenly getting a white screen with an error message.........unfortunately process com.android phone has stopped. At the top of the page it say Encrypting and below that is a box that says reset phone. I have tried rebooting. Pulling the battery. Pulling the cards. Nothing works. That is the ONLY screen I get. It was purchased through T Mobile 4 years ago. It was unlocked and is currently on the ATT go phone system. Please help me!

Welcome to Android Central! I'm assuming you have an Optimus L9.

Unfortunately, you can't wipe the cache partition on that phone (assuming it's not rooted, with a custom recovery installed). If nothing works, then try doing a master reset with the hardware keys: https://support.t-mobile.com/docs/DOC-5771
