First off, thank you for the guide! I'm having some problems with the LG Flash Tool. After "Waiting for connection" I get this error:

PID: NULL
IMEI: Unknown
Model : UNKNOWN
DLL : LS740
BIN : LS740ZV3_17.33030_SECURE.TOT
SW : UNKNOWN
SWOV : UNKNOWN
Device Model is different!
Check Phone or DLL!
00000000
Factory Model Check ERROR!!

Any idea what's going on? I followed the steps exactly, tried 4-5 times, and keep getting the same error message.

I am also seeing the same error. It is for a Sprint Volt, activated on RingPlus network.

On another note....how many folks, other than you OP, have successfully done this? Cause I haven't seen many success posts TBH...

I've had success with doing no this with both the Boost and Sprint versions of the Volt.

Sorry you're having so much trouble. :( It seems the LG Flash Tool is not detecting the phone properly. If you boot the phone into Android and then plug it into your computer via usb, does Windows detect it and load the drivers properly?

Yup never had a problem there. My PC recognizes it as soon as I plug it in. Getting ready to give it another go, downloading all the files again as we speak. Here's hoping it goes well but if not then I give up....for now lol

Since you already checked the MD5's earlier, I don't think re-downloading the files will help, but here's hoping that I'm wrong. :) If it still doesn't work, you might put all the files on a USB stick and see if a friend will let you try it on their computer. Since you had other drivers on your computer previously maybe that is a factor. I did have Samsung and HTC drivers on my computer previously though, and it didn't seem to cause a problem for me.

Spocko, thank you for the input, but all of that is in my post.

Uh, no it wasn't. :) I added some additional details, MD5's, screenshot of download mode, and most importantly the correction related to MegaLock.dll.

Added (MegaLock.dll) to the guide. Apologizes...I thought it was included with the flash tool.

Thank you sir. To be clear for others, a file called MegaLock.dll is installed along with the LG Flash Tool, but it's not the correct version for our phones. It is necessary to download the separate MegaLock.dll and replace the default one in the LgFlashTool program folder after you install the LG Flash Tool.

I know the flash tool has a megalock dll with it, but I thought the person that uploaded the zip included the hacked one as well.

To be specific, the megalock has nothing to do with the phone. It's a security thing. The modified one bypasses the password prompt.

Anyway, thank you for the additional details. I will include the md5s in the guide tonight.
 
Ok i successfully rooted my volt with the guide posted here, thanks for it, it was actually very simple, i had a issue with sd card not mounting in cwm but i swapped sd cards and voila it worked, thanks all

Did you ever get this working?

I passed out way early last night but I'm gonna give this a go now before work. If I could just get this thing downgraded I'm sure the rest will be smooth sailing.

What if you factory reset your phone, then try to downgrade?

I know that's annoying, but there's nothing else I can think of at this point.

Quick question. I am on RingPlus network. So, I guess my "PRL" and "Profile" is updated for RingPlus (instead of Sprint). May PRL/Profile play any roll? I tried dialing ##72786# (to clear PRL/Profile ???) and then tried flushing. That failed as well.

No, that would have no impact. There is some communication problem between your phone and computer. None of this has anything to do with what carrier you have.

Wondering ... does the flushing tool generate any log which may provide more info? Thanks.
 
Yes, there is a folder in the flash tool folder called log. It's in there.

I've updated the flash tool in the guide to v1.8. I just noticed that is what I have on my computer.

Ok, I've spent like the last half hour tweaking the guide to include current versions and MD5s.
Any other input for improvements welcome. :)

Thanks to spocko for input and that awesome hash checker! :)
 
Any advice on installing the LG drivers on a Linux system? Running Ubuntu 10.04 (lucid lynx.) Or am I better off just using a windows system for the downgrade and flashing process?

There are no Linux drivers...I don't believe you actually need any.
However, I don't know how to go about this process in Linux.
Someone else may be able to assist you, or just use Windows.

On another note, that's a pretty old version of Ubuntu...any reason for not upgrading?

Well, the box I have now has an onboard gpu, that isn't quite up to snuff to run the newest distro's unity requirements. I suppose I could switch to xubuntu or another distro, but I'm really happy with the stability and function of my current version.
