Drivers: LGE739 Support

How to get into emergency mode (Download Mode):
1. Phone must be off and unplugged
2. Hold Power+Volume Up+Volume Down

To get out of e-mode, pull battery and unplug USB cable (do not do this while flashing firmware!)

These are the instructions to flashing the KDZ:

1. Install phone drivers (reboot might be required after to get them to recognize the phone)
2. Install msxml.msi
3. Open KDZ_FW_UPD.exe
4. "Type" choose 3GQCT
5. Choose in "Phonemode": Emergency
6. Click the folder icon and choose the kdz file that UpTestEX_mod2_marwin.exe just made.
7. Click Launch software update and enjoy!

If you were running CyanogenMod before, you will have to factory reset:

I followed the instructions to a T and when it rebooted it's still stuck on the LG screen. I ended up bricking the phone after installing clockwork mod and tried to boot to recovery. Now it wont go to anything but the LG screen and the S/W screen. I keep trying the manual recovery but I cant seem to get that right. Help please!

i keep getting an error that says it can't find a dll file or something like that. what is it talking about (using the kdz program directly), also, it doesn't seem like it's doing anything, is there a complete walkthrough for any of these programs? just for confirmation i've got the E739 and the KDZ and other files

Unplug your phone, pull battery, put in battery, plug in USB cable, try again.
