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 computer
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 files
, 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, connect
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 solutions
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:
the LG Vu firmware files from this site (http://www.lg-vu.com/index.php?topic=3902.0)
. Unzip it. These files contain the entire LGAPP firmware folder. Then unzip it. It should create a LGAPP directory
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.
