maybe this will work.

conect your phone with the usb port.
start in windows the program EFS MEDIA BUILDER by AKOM1976.

select connecton and after that you choose efs explorer select connection.

Now you see the files on your phone
maye there is a folder named as TOTO
be sure that this folder is on your phone!!!
If it does delete the folder named as LGAPP
after that rename the folder named TOTO to LGAPP

richt click and choose refresh.
now exit the efs program.

Turn your phone off and then after a few seconds on
the phone will startup normaly as always and its normal asual.

I hope this will work or you have to back up with the LGMDP euro
an after that choose restore and choose the image file *.nv2

This will work!

hi open EFS connect phone with USB click EFS explorer click your phone on the top half of the box, find a folder u named TOTO rename it to LGAPP click disconnect warning box may appear just click yes if so now your phone should restart and work normally ;) if not, contact me at my youtube account: addol95
