I've updated my phone. Lost my root.

Here are the instructions that got me successfully back to STOCK ROM that is still rootable.

EDIT #2: USE AT YOUR OWN RISK!

Instructions:
1. Get the LGNPST Package with the GenericModels and Components Plug-In.
http://www.megaupload.com/?d=GQ0P3XM7

2. Get the driver for the phone and install it.
http://www.lg.com/us/support/mc-support/drivers/LGAndroidDriver_Ver_1.0_All.exe

3. Get the Stock Rom TOT file and extract it.
http://forum.xda-developers.com/showthread.php?t=1120062

4. Get the DLL file specifically for the Revolution
http://forum.xda-developers.com/showpost.php?p=14850289&postcount=19

5. Extract the "LGNPST Store & Lab"

6. Install the following order:
a. LGNPSTv1.2_Store_Version.msi
b. LGNPST_v1.2_Lab_Version.msi
c. Components >> LGNPST_Components_Ver_5_0_12_0.msi
d. GenericModels >> LGNPST_GenericModels_Ver_5_0_10_0.msi

7. Run "Right_Click_Register_DLL.reg"

8. Make a new folder called "Models" in the program's directory
Default: "C:\LG Electronics\LGNPST\"

9. Grab the "VS910.dll" and put it in the "Models" folder.

10. Right Click "VS910.dll" and click on Install.
Note: DLL WILL NOT INSTALL UNLESS COMPONENTS AND GENERICMODELS PLUG-INS ARE INSTALLED!!!

a. Make sure you install it properly
b. REBOOT!!

11. Run "LGNPST"

12. Plug in your phone, use Internet Connection Mode,and enable USB Debugging.

13. Phone should pop up in the list

14. Select the phone and click on the Open folder button inside the .BIN query underneath the COM## details.

15. Since it wants a .bin file, you can open the .TOT file by typing "*.*" inside the File Name query and hitting Enter

16. Select "VS910ZV4_04.S4_04.P58008.R5.user.tot" and Click OK

17. Then click on Upgrade

18. Wait a few minutes

19. Voila

EDIT: To all users running 64bit versions of Windows, you guys may run into problems since I only tested this method under a 32bit environment of Windows 7. I will attempt to get my hands on a 64bit version of Windows 7 to test some more and make a instructional Youtube video to help out everyone soon.

EDIT #2: Been busy, Haven't got a chance to make a youtube video yet.

Not sure but maybe after doing this and obtaining root you can flash over to decrap rom or revolt rom and maybe that would fix the issues? Just a thought





Sent from my VS910 4G using XDA App

Somehow i dont think so usually a tot is a full bin file that writes everything including the radio if this tot messes that up or doesnt complete properly u can have problems potentually even a brick

I believe the users that have a failed downgrade had a problem with the .TOT file being downloaded properly and they probably had the phone in CDMA mode only when the phone should be in LTE/CDMA mode.

But if anything, they may have unplugged the phone before the program finished because the phone looks like it's done being flashed but the flash program says it's 80-90% complete.

Make sure you DO NOT unplug the phone until the flash program say it's safe to do so.

A note to all. If you have the drivers installed form earlier. UNINSTALL THEM!

Then restart. Install Verizon's drivers when you first plug your phone in while in 'Mass Storage' and THEN install those drivers. I had some problems getting it to work but that fixed it a bunch. Also, if you are getting a 0x800 error while trying to install the DLL, open CMD with Admin privileges and then 'regsvr32.exe "C:\LG Electronics\LGNPST\Models\VS290.dll" and it should install correctly.' I would suggest rebooting after this then running the tool.

my phone isnt showing up in LGNPST...

how can i fix this?

You can try to update the drivers.
Reboot.
Turn on LGNPST.
Plug the phone to a DIFFERENT USB port.
Make sure USB Debugging is switched on on the phone.
Wait for the phone to install.
Voila.

I think LGNPST may have a refresh problem but that is what repaired the issue for me.

This Method works and is the same way I recovered my last Revo. Not sure what may have caused the issues for that phone. Using this method on the new replacement has been successful and still no problems with the phone. Did a S1C and rooted successfully and installed CWM using ADB without a hitch. Then came decrap 1.1 Life is great.

You have to unzip the directory. Once that is done then the option will appear. If you still need help tonight then you might find me on irc. Im sure i can help you there. Message me if you dont figure it out.

I'm using win7 x64bit and the registry key that adds the right click register option wont work for me either. The manual .dll registration worked though after a reboot.
