How do you fix your blinking lg logo on LG optimus?

Answer 1

I have an LG Optimus U (US670) that had the same problem with the blinking logo, I was able to fix it with a hard reset.

NOTE: This didn't work the first time i tried it. I didn't work the second time either, or the third, or the fourth. Six times is the charm for me. So if it doesn't work, KEEP TRYING! Because, aside from sending your device in to be serviced, there really is not much else you can do. Also, removing the battery for longer periods of time each try might help.

WARNING! A hard reset will remove ALL information, contacts, apps, etc. on the phone and return it to it's factory default settings. AKA: Factory Reset. Anything on the SD card 'should' be untouched. But I can't guarantee it wont remove any information stored there. I suggest backing up anything you don't want to loose (if possible) before continuing.

Now that you know the potential risk, here is how to perform a hard reset:

1. Take the battery out for a few minutes, then put it back in.

2. Hold the Menu and Volume Down button for a second then press and hold the Power.

3. Follow any on-screen instructions.

This method supposably works on most smart phone models. But again, I can't guarantee anything, as I only have the Optimus. If it doesn't work after trying it several times, I suggest taking your phone back to your service provider and seeing if they can help or possibly exchange it. That is assuming you haven't done anything to your phone that voids your warranty (like rooting).

My device did eventually power on at step 2 like normal and I didn't loose any information. I don't know why. I sincerely hope this works for you, I'm certainly glad it did for me. Good luck.
