Install an IR Remote App in android phone. The app link below worked for me to remove the fpa lock on. Configure the App for your RCA TV. Set TV as Device type, RCA as the brand. and choose the model (e.g., TV 20 F420T) also, select the Alternate IR Driver.

It sounds like you may have accidentally turned them off. To make sure the sounds are on, do the following:

1. Click on "Settings"
2. Select "Sounds"
3. At the bottom you will see "Lock Sounds" and "Keyboard Clicks".

If the sounds are on, I would then recommend preforming what's called a "Soft Reset". To preform this, do the following:

1.Press down the "Home" button and the "Lock" button at the same time.
2.Hold these buttons until you see the apple logo appear.
3.The iPhone may take up to 2 minutes to come back to your "Lock Screen"

This should fix your problem.

That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.
