You must be running Windows XP/Vista/7
(Not sure about Windows 8)

Downloads
Download firmware from here: http://androidforums.com/connect-4g...8-official-connect-ms840-ms840v-firmware.html
Download the programs to convert and flash firmware: KDZ_FW_UPD_EN.zip
Drivers: LG MS840 Support: Find Manuals & Warranty Info | LG USA

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

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


Before you start flashing firmware, please make sure you charge your battery for at least 30 minutes/over 50%

These are the instructions to convert the cab to a KDZ and flashing it:

1. Install phone drivers
2. Install msxml.msi
3. Disable antivirus software
4. Open UpTestEX_mod2_marwin.exe
5. Wait for the program to open
6. Look for "Encrypt cab file to kdz file"
7. Click the folder icon
8. Choose the location of the cab you downloaded for the firmware
9. Encrypt cab -> kdz Program will freeze up. DO NOT EXIT until program says Done!!! Otherwise it won't finish converting.
10. Close program
11. Open KDZ_FW_UPD.exe
12. "Type" choose CDMA
13. Choose in "Phonemode": Emergency
14. Click the folder icon and choose the kdz file that UpTestEX_mod2_marwin.exe just made.
15. Click Launch software update and enjoy!

My phone doesn't want to connect to my computer!!! I installed the drivers and everything and nothing worked. I've even uninstalled the drivers then installed a newer version driver and still nothing.

No. It wil be a .kdz file in the same folder as the firmware's .cab file that you specified when during the "Encrypt .cab to kdz" step.

So I just went from LDrifta's Number 2 (ZVA) to VV4, but didn't wipe data/cache first so all my apps and stuff are still there. Is this bad? Do you think it'll be gummed up without a wipe?

By the way, the process worked great. You may want to add a note that the phone may reboot during the process of installing the KDZ (I freaked out for a second thinking I ran out of battery or something), but other than that, flawless instructions/zips. Thanks all.

Here's what happens.
I choose the VV5 zip that I download and press encrypt, it just opens another folder. Is that supposed to happen?
Then when I select the KDZ file and click start upgrade, I get an error. What am I doing wrong?

If the downloaded cab isn't the full size, then yea. You'll find out when you try flashing it whether it was a good or bad download. It will keep failing if it's a bad download.
