    Hi please follow the guide by gbiggie if your downgrading his guide is much more explained, updated and better and he can also assist you all the time http://androidforums.com/esteem-all-things-root/479734-guide-downgrade-ms910zvc-ms910zvb.html


    Ok to start up thanks to user Jackpot08 a lot for posting the .TOT files and LGpnst big thanks to him.

    To start off first download this files Multiupload.com - upload your files to multiple file hosting sites! (LGPNST) Free File Hosting, Online Storage &amp File Upload with FileServe (ESTEEM'S ZVB STOCK TOT or IMAGE)

    The drivers can be obtained when you connect the esteem to the computer it will show up as a cd drive in MY COMPUTER

    Since MS910.DLL does work anyway i will provide the one that works which is VS910.DLL link Multiupload.com - upload your files to multiple file hosting sites!

    After your done downloading all the file extract the "LGPNST.zip" file where it will be easier for you place the MS910ZVB_01.SB_01.P3018.R1003.tot file on your desktop as well

    then install..

    Then navigate to the folder named "Components" and install this "LGNPST_Components_Ver_5_0_12_0.msi"

    Next navigate to "GenericModels" folder and from there install "LGNPST_GenericModels_Ver_5_0_10_0.msi"

    Next go back to the original folder where "Right_Click_Register_DLL.reg" is located, run this file it will ask if you would like to merge this to the registry, click yes this will add "Register DLL" when you right click on a DLL to register which is our next step

    I will suggest that you extract the vs910.dll on your desktop and from there Right Click on the VS910.DLL and click register it will register and will create to other files .XML dont touch them please so then our dll is registered. (make sure you have followed the guide and installed the components and generic models as stated above PLEASE IMPORTANT)

    Reboot your computer

    next connect the LG Esteem phone to your computer once the usb is detected and shows up on your notification bar, from the notification bar please chose INTERNET CONNECTION mode. Once you do that open device manager on your computer and under com ports you will see the LG com port (ignore this)

    Next open LGPNST which is also located on "C:\LG Electronics\LGNPST\" once you open it and if you have followed the directions closely the lg esteem will show up as unknown device dont worry about that please

    From LGPNST click File select DLL browse to your desktop and select VS910.DLL

    NEXT Check this picture out please and do as same View image: LGNPST First page VERY IMPORTANT i downloaded and edited it little but it will look like this.

    Next the upgrade option will be visible click it and from there go to BIN FILE and you will see a little folder icon click that and it will let you browse where your .TOT file is

    Once the dialogue box opens navigate to desktop where you downloaded or copied the MS910ZVB_01.SB_01.P3018.R1003.tot file because it wants a .bin file, you can only open the .TOT file by typing "*.*" inside the file name query and hit enter and you will see the tot file visible if not copy and paste this to the file name query MS910ZVB_01.SB_01.P3018.R1003.tot and hit enter it will be loaded.

    Next click upgrade wait for it to finish and your happy :) Please MAKE SURE THE PHONE IS SAFE AND THE CABLE DOESNT GET UNPLUGGED OR THE PHONE, dont trip on the wire dont jump on it nothing :p. (also make sure the phone is charged atleast 30% or you will have to wait till it charges this will work gurantee i have done this COUNTLESS times with my Esteem ever since the .TOT was released and also been flashing my KU990

    BTW I know its LGNPST not LGPNST sorry gotta work cant fix all the mistake lol

    Those who have updated to the latest zvc update for lg esteem, but regrets it and wants root back you can downgrade back to zvb and its confirmed just did it my self right now

    Please follow this guide to downgrade http://androidforums.com/lg-esteem/454895-12-3-11-lg-esteem-ms910-firmware-w-instructions.html dont worry about the dll not registering download the vs910.dll put it on your desktop register that one instead open lgpnst put the esteem in internet connection mode so lgpnst detects the phone click file select dll and select the vs910.dll ok then click on the mode that says unknown and the upgrade option will become clickable from there follow on the guide from here http://androidforums.com/lg-esteem/454895-12-3-11-lg-esteem-ms910-firmware-w-instructions.html and then your back to zvb

    I would like to downgrade from C to B, however I'm hesitant to try this method out since there isn't any confirmation about it or anything. Anyone try it yet?

    to those who venture out and give this a shot, good luck! yeah it's not that i dont trust that it worked for you so much dual it's just that the guide is not very clear and some steps seems confusing. maybe a new line for each step would be more clear.

    also, after you successfully downgrade, is it just that, a downgrade, or do you lose anything like contacts etc?

    Any time you change software versions you lose everything so make sure you back up your stuff.

    This has been a public service announcement.

    Ok here it goes..!

    Everything done through step 5. Extract the "LGNPST Store & Lab"

    LGNPSTv1.2 Store_Version.msi installs fine. When I try to install LGNPST_v1.2_Lab_Version.msi I get "ERROR 1314. The specified path %APPDATA%\ is unavailable.

    hmm this kind of warning mes safe seems like there is either some registry corruption or btw ur logged in as admin in your computer right try to do a registry cleaning CCleaner - Standard using this program also when you chose to install the lgnpst change the directory to something else bro btw u have uninstalled all the previous version right try doing those and see if it helps

    Okay, so like before it keeps saying failed to load skin.dll. in my other computer that will let me open lgnpst, there is a application extension that says skin.dll while in lg electronics folder, but when im on windows xp, it just doesnt even give me a skin.dll. might sound confusing but if i can open lgnpst and get rid of the failed to load skin.dll i will be able to succeed with this. Any thoughts on how to open and get rid of the "failed to load skin.dll error"?
