1. Go to the LG website and find your phone, download the USB drivers and mobile support tool.
2. Install the USB drivers, remove the battery from your phone and note the model number, serial number and IMEI number then replace the battery.
3. Turn on your phone and plug in your USB to the computer and phone and wait for the drivers to install.
4. Click your 'start menu' and select 'Computer', click the 'Tools' menu at the top left of the screen and select 'Folder Options' and then the 'View' tab, put the radio dot in the 'Show hidden files, folders or drives', also remove the check-mark from 'Hide extensions for known file types' and click 'Apply' then 'OK'.
5. Run the mobile support tool 'exe or setup' file, select the emergency firmware recovery thingy and enter your phones I.D from earlier
When the mobile support tool finds your firmware download, click to download it.
6. Immediatly navigate to 'C:\ProgramData\LGMOBILEAX\Phone\' where you will find your firmware file in the process of downloading (mine was called 'V10A_00.kdz').
7. Keep an eye on the mobile support tool to see when the download is going to complete, before it does right click on the white background of the 'C:\ProgramData\LGMOBILEAX\Phone\' folder and select 'Refresh' to update the firmware files downloaded file size - ideally do this several times during the download process to allow Windows to calculate the file size faster at the end and produce a useable '.KDZ' firmware file before the mobile support tool get's too far into the process of extracting it.
8. Once the mobile support tool changes from the downloading screen to the flashing part grab your firmware file and drag it to the desktop or any other location to copy it, you only have a small amount of time to do this before the mobile support tool extracts the files and deletes the '.KDZ' file so don't worry about scratching your arse just yet!
Just a note, I also copied the extracted '.CAB' file and 'DIAGCommand.xml' files for no real reason!
9. Once Windows has copied it and the 'File Copy' box closes YANK THE USB LEAD OUT OF YOUR PHONE!
If for any reason your computer takes longer than 10 seconds after the download finishes to copy the file then pull your USB lead if you don't want the phone updated and go buy yourself a decent computer!
If you wait any longer than 10 seconds after the download completes you may well brick your phone which I'd like to add I accept NO responsibility for, not even if you follow my method to the letter and still end up bricking your phone I promise you I won't lose a moments sleep over it!
What I can tell you is that the 10 seconds time frame I give is an over safe time frame. In reality your phone will not start to flash any data until it reboots so I suggest having the volume turned up to listen for the USB disconnect / reconnect sound. At the very latest remove the USB cable after the disconnect sound but if you hear the reconnect and the cable is still attached you have 2 choices, 1: Do nothing and have an updated mobile phone or 2: Pull out the USB cable and have no phone. YOU HAVE BEEN WARNED!
Hope this helps you. Please 'Thank Me' if it does.
P.S. You may now want to go back to your Computer/ Tools/ View folder and set them back to default.
