How to fix fatal error

In order to fix your phone, you need to be calm and patient. Make a wrong move and no one will be able to help you.

Method A) First thing to do is determine if you can connect your phone to your computericon1.png and open its file-system up. If you can, just replace the files that you messed up with the original files (If you didn't back-up get the files above) and then restart your phone.

Method B) If you cannot access your file-system because your phone is constantly rebooting, the first thing you need to do is turn your phone off. If the on/off button doesn't work, pull the battery out to turn it off (DON'T TURN IT ON). Then connect your phone to your computer (While its off, and it should turn on by itself and go into a charging screen) and see if you can access your phone's file-system, again if you can replace the messed up filesicon1.png, and restart your phone.

Method C) If you STILL can't access your phone file-system, don't fear there's still hope. Some users have reported success using this method, but it may or may not work for you. Try holding all 4 buttons (camera, lock/unlock, and volume rocker) on the side when the phone is starting, see if you can get it to a white screen with information stating "This phone has the IMEI. If you want to make the gang image erase the IMEI," if you see that, connecticon1.png your phone to your computer and replace the files, then restart.

Method D) If you find that you cannot stay in the gang image screen above, meaning it turns blue/black with error fatal when you connect to the phone, then do this: Remove the SIM card out and turn on the phone. Hopefully you will get the emergency call screen to display (where you can only make 911 calls). Connect to your phone now and replace the files.

I also got the fatal error screen and another way to get it to the gang image screen is to remove your sim card and leave the battery in then plug it into a wall charger and then use the four button thing to take it to the gang screen, after it gets there unplug it from the wall charger and plug it into the data cable and the screen will remain at the same position..

This is Basically a Factory Reset for your phone. Try the other solutionsicon1.png above, then go for this one. Kind of a..Last Resort i guess you could say.. This is also known as the "GrCobb Method"

I had the same type of problem and had trouble resolving it by putting back the files I thought I had changed. I was getting LG's 'blue screen of *****' with a message like Fatal Error: Dog: 1 or something like that. Here is what I did:

1. Downloadicon1.png the LG Vu firmware files from this site ( Unzip it. These files contain the entire LGAPP firmware folder. Then unzip it. It should create a LGAPP directoryicon1.png with every file that was on your phone when you got it. I know DH said to not replace the entire LGAPP folder because it may brick your phone but, hey, it's already bricked so not a problem.
2. Get into EFS and connect with your phone. Get to the gang screen on your phone using the steps if you have to.
3. Rename the LGAPP folder to something else (LGAPP_bad). Do not delete it. There are some files that are read only and you get an error message replacing them when you copy the new GAPP on top of an existing LGAPP directory. This doesn't happen if you rename the old LGAPP to LGAPP_bad before you do the copy.
4. Copy the LGAPP directory you unzipped above to the phone and restart it.

That is what I did and it came back to a clean state as if you did a factory reset.
Hope that helps.

LG viewty doesn't turn on!

If you know that the phone is having problems with software:

Turn on the Gang image mode on. Do this by holding the red phone button + C + green call button + lock button at the side of the phone. Hold all these buttons at the same time so the screen becomes yellow saying "Gang image mode".

Next download EFS explorer onto your computer, connect your phone with the USB cable. You should be able to access your phone. There are other sites which tell you what to do more clearly. - go to forums and find your problem

Assigning a picture to a contact

All you need to do is change it so its either.. the contact is a SIM contact or.. umm ... i can't remember the name .. its under options but you can change it! I have the phone but right now mine has a broken L C D screen so i can't look to answer that 100%

But i figured it out after my brother gave me that phone - he said he couldnt do that but i figured it out in 10 minutes.

Something to do with when you make the contact you need to change it to either the SIM card or um.. i cant think of the other name butthere are several options for what you save it as.

If that helps!
