'via Blog this'CAUTION: any time you flash your LG Eve/Etna GW620, you run the risk of bricking your phone. I will not be liable. LG Phone Problem and Solution

1. Download and install the LGUSBModem drivers (I used the popular 4.9.4 version – LGUSBModemDriver_WHQL_ML_Ver_4.9.4_All.exe). Do not have USB Debugging mode enabled on the LG Eve/Etna GW620.
2. Download and unzip LG-Utils-0.4.2.zip.
3. Download B2CAppSetup.exe (and run it, it will download the full app from LG).
4. Download the update for your phone (.kdz file).

5. Root the LG Eve/Etna GW620:

   1. Enter this on the handset to get to the hidden menu: 3845#*620# (3845#*5200# on Korean firmware)
   2. Select: Module Test -> Stability Test -> Enable Root Permission
   3. Newer roms require a password: EVE&ADAM&&620LOVE!

6. Extract the kdz file to a cab file:

   1. Run KP500-Utils-EN.exe (from LG-Utils).
   2. Choose "I – Extract files from a KDZ file".
   3. Enter the path of your .kdz file, it will produce a cab file in the same directory.

7. Flash the phone (turned on in normal mode, not emergency mode or fastboot):

   1. Run KP500-Utils-EN.exe (from LG-Utils).
   2. Choose "J – Flash with assistant (file .cab)".
   3. Enter phone model "GW620".
   4. Enter path to your newly created .cab file.
   5. Enter new software version (e.g. "V10G_00").
   6. The LG flasher will be launched and should connect to the phone and do the job (it will reboot a time or two and go into emergency mode, so don’t panic if you see this). LG-Eve/Etna/Intouch Max info

8. After flasher completes, and phone has rebooted, do a factory reset:

   1. Enter this on the handset to get to the hidden menu: 3845#*620# (3845#*5200# on Korean firmware)
   2. Select: Factory Reset-> Factory Reset
9. Factory reset un-roots the phone, so after reboot re-root it again (as above).
