Root [Guide] Using LGNPST 1.3 to FULL Stock ZV5

[sammyz]

Have you ever wanted to return your phone to full stock? Was your phone a ZV4 that would never update to ZV5? Did you screw up the ZV9 update? Well this guide is one of them most easiest ways to Upgrade/Downgrade/return to Stock.

What you need:
Drivers: look here
VM670.dll.zip
LGNPST 1.3 (It must be 1.3, 1.2 WILL NOT work!)
LGNPST Components----Thank you asadullah!
ZV5 Firmware: VM670ZV5_07.cab
Phone must be in Recovery Mode or booted in Froyo ROM
Your SPC code, get it by following the youtube video, Thank you asadullah! Click Here

Step 1: Install LGNPST>Reboot>Extract and install everything in LGNPST Components.zip

Step 2: Extract VM670.dll to C:\LG Electronics\LGNPST\Model\MTP (create folders if they don't exist and Right-click VM670.dll press Register Active X DLL

Step 3 (If you're doing this from recovery mode, skip this): Dial ##PORT# Enter SPC, Check the box. Open LGNPST

Step 4: THIS IS IMPORTANT! Rename the VM670ZV5_07.cab to VM670ZV5_07.S5_07.P61007.cab

Step 5: In the Upgrade tab choose the CABfile and browse to where you extracted and renamed the file, select it.

Step 6: Press Start, enter SPC, Press OK

Now just wait for it to finish and then for the phone to boot. If it does not load after 5 minutes after LGNPST hits 100%, unplug USB, turn off phone by pulling battery, press HOME+POWER+VOLUME DOWN, you are in Stock Recovery, select factory reset with the home key and then reboot.

Now wait for it to boot. Once it boots you are done!

Very cool Sammy. A couple things... Why not rename the cab and re upload? Also how about zv4 firmware? It had the bootloader unlocked and im curious if this method could regain bootloader access.

I'm guessing that he didn't want to confuse people that don't know that zv4 and zv5 have differnt screens.

 

[Thewraith420]

I'm away from my computer now but I was trying to get setup to try and downgrade from zv9. when I try to register vm670.dll it spits up an error and dosent register. Its on winxp pro. I'll post the actual error tomorrow morning.

EDIT: It's "LoadLibrary("C:\LG Electronics\LGNPST\Model\MTP\VM670.dll") failed - The specified module could not be found."

Did you follow step 2?

Step 2: Extract VM670.dll to C:\LG Electronics\LGNPST\Model\MTP (create new folders if directory does not exist) and right click the extracted VM670.dll and choose "Register ActiveX DLL"

If anyone wants ZV4, you can PM me, asadullah also has the link to it. And Phatninja is correct, I don't want people accidentally flashing ZV4 on phones with the new screen.......

Does the directory already exist? Because there's another way to register it if it does, if it doesn't then I need to upload another thing..

no i had to create the directory

 

[sammyz]

no i had to create the directory

alright, hold on while I upload the files and edit the guide....I had LGNPST 1.2 so some stuff already existed...wait, I had to create those directories too with 1.2...

 

[sammyz]

Updated Guide, new download added, it is needed.
Reggie.zip
Step 2: Extract Reggie.zip to C:\LG Electronics\LGNPST\ so that after it is extracted you will have directory \Model\MTP

Step 2 1/2: Extract VM670.dll to C:\LG Electronics\LGNPST\Model\MTP and

-If on Win7/Vista right-click Reggie.exe>Properties>Compatibility tab>Check Run as administrator>Ok then drag VM670.dll over Reggie.exe and drop it.

-If on Windows XP drag VM670.dll over Reggie.exe and drop it.

When I have time.

ok new error with reggie.exe

"This application has failed to start because LGNPST_GenericModel_Ver_5_0_10_0.dll was not found. Re-installing the application may fix this problem."

this is what i get on dragging vm670.dll onto reggie.exe

EDIT: Followed asadulla's link in the unbrick thread and installed lgnpst components and genericmodel specified in the OM thread and the dll registered fine with the right click method. no reggie needed

In the OM forums their's a thread "How to get out of fastboot" the driver there should work.

They didn't seem to do the trick ill play more tomorrow with it

So I decided to try bootloader from my Linux box and yes bootloader is accessible. Definitely a good thing for us zv4 owners

And ZV4 owners can upgrade to ZV5 to get 2.2.2 on their phones

This removes bootloader though.

 

[Petrah]

Amazing guide, Sammy! I just completed it and am now back to ZV5. I've no idea yet if this will fix my 3G issues, but I will report back later.

Will also be linking to this guide from the ZV9 guide.

 

[Petrah]

Can you explain that, pretty please?

 

[cammykool]

mom you missed my part can us hitachi owners go to zv4?
