Hello,

It seems that there is no much thead here on XDA when I search, have you tried to search on Google: "how to reset LG F160s Optimus LTE2" and take a look at the fourth result.

Read and follow the procedure closely.

If you have not a good result, you should ask your question in this section: Optimus 2x Q&A, Help & Troubleshooting.

Good luck!
