I am wondering if that method is still good,or should i try another one?I have tried to find a thread where there is explained how to flash using cwm or twrp,but was unable to find it so i would be very greateful if someone points me to a thread where there is explanation on how to do that.
For bootloader: http://forum.xda-developers.com/show....php?t=2224020
Then follow instructions from second
After you do steps from 0 to 3 (dont forget to put files into your internal memory), you will turn off your phone, press and hold
power and volume down button simultaneously, when LG logo appears, press power button three times while still holding
volume down, then you can release everything and you should be into recovery witch should look similar to this http://techbeasts.com/wp-content/upl...12/la-foto.jpg
. Now you do steps 4-7, in backup and restore (witch is step 4), just press backup and wait a minute or two for backup to complete. Then go back and press install zip from sd card, then navigate to ROMs zip file you downloaded and click it. You will see output screen showing progress... after ROM is flashed, go again to install zip from sd card, this time you will chose gapps zip file. After that, go back, do wipe data/factory reset, wipe cache partition and in advanced tab wipe dalvik cache. Go back, reboot and you should be done!
IF anything goes wrong with flashing, you will reboot into recovery and go backup and restore, and restore.
