    : After flashing back to v6 if you can't receive OTA updates please download and flash stock recovery from here: Stock Recovery(Ally) Then do a hard reset (Vol-Down+Home+End). Sign in with google, then do *#*#CHECKIN#*#*

    Hello everyone, just thought i would post this how-to thread since my post in the Ally V9 SW Update is buried.

    Flash Stock LG Rom.

    Disclaimer: I put my phone on the line to try this and it worked fine for me doing the steps i detailed below.
    It is possible to brick your phone doing this so be careful. I am not responsible if you end up with a ~$500 paper weight.

    You have been warned.

    If you are still with me, here are the steps:


    To enable USB Debugging: Settings>Applications>Enable USB Debugging

    Download LG MOBILE UPDATE TOOL W/ ALLY DRIVERS (Only if you do not have either one of these installed)

    UPDATE: If you are having issues please download these drivers: LGAndroidDriver, install and then follow the instructions.

    Update 9/08/10: It has recently come to my attention that if you have used roms and custom recovery and you try to restore to stock you get stuck at the A N D R O I D screen.
    The Fix: Boot into recovery and wipe data+cache and dalvik cache then restore to stock again.

    Update 11/04/10: User Mael has recently pointed out to me that he is using windows 7 ultimate (i'm running home premium) and he was having a problem with the files he downloaded being blocked my win7's security settings. Right click on the cab file and if it displays it is blocked because it came from another PC, unblock it. do this for the vs740 folder as well. make sure sub folders and files are included. Thanks to Mael for this solution.

    Step 1: If you haven't done so already download VS740.zip
    and save to the root of your C:\ drive.

    Step 2: Open the zip file, and drag the folder to the root of your C:\ drive

    Step 3: Open this folder that you have just downloaded.

    Step 4: Rename the cab file to VS740ZV6_01.cab (If you do not see the .cab extension DO NOT add it. Also You may not have to rename it if you downloaded it as the same name.)

    Step 5: Extract the zip file's contents to this folder and connect USB cable to phone.

    Step 6: Run KP500-Utils-En.exe in compatibility mode for Windows XP SP2 and as an Administrator.
    (Only if you are not running windows xp)

    Step 7: Choose option J.

    Step 8: Type VS740 when it prompts for phone model number. Press Enter.

    Step 9: Type VS740ZV6_01.cab when asked for the cab file. Press Enter.
    (You do not have to tell it what directory the cab file is in)

    Step 10: Type VS740ZV6_01 when prompted for the version. Press Enter.

    Step 11: It should now tell you it is loading and the familiar lg manual updater screen will appear with a log window below
    and start reading information from your phone and then it will flash it.
    If the firewall says its trying to access the web allow it.
    Your phone will switch to a screen that displays the LG and Verizon Wireless logo and say: DOWNLOADING! DO NOT UNPLUG!

    It will flash the update to your phone and takes around 20 minutes to complete.
    Once complete it will boot up and show the word android on the screen.

    It looked like it hung at that screen but it didn't it just took a while. Around 10 minutes.

    Once this is complete you may unplug your phone from USB.

    UPDATE!: After you finish flashing stock rom, Power off and press and hold
    Vol Down+Home+End and when it loads back up open the dialer and dial *#*#CHECKIN#*#* to force your phone into downloading the v8 update. and then VZB Update

    Congratulations! If successful you now have the stock LG Rom. Enjoy!


    Got the stock rom running, but need stock recovery to get OTA updates?


    Download the stock recovery image here:
    Extract to sdk/tools folder (eg: c:\android\sdk\tools)


    Step 1: Start a command prompt and navigate to where the sdk/tools folder is extracted (eg: C:\android\sdk\tools)

    Step 2: Type:
    Code (Text):
    2. adb devices (to verify the phone is recognized by adb)
    4. adb reboot-bootloader
    Phone should now be on a blue screen

    Step 3: Now open device manager

    Step 4: Expand adb bootloader device or something similar. (should be at top of device tree)

    Step 5: Right click and choose update driver

    Step 6: Choose i will choose driver to install,

    Step 7: Navigate to where android usb drivers are (eg: C:\android\sdk\usb_driver)

    Step 8: Choose the android_winusb.inf file

    Step 9: Accept that this is an unsigned driver.

    it should say the driver was successfully updated

    Step 10: Go back to command prompt and type:
    Code (Text):
    2. fastboot flash recovery stock_recovery.img
    4. fastboot reboot
    Congrats you should now have the stock recovery!

    It is saying that my phone is not connected. The log says normal connection, then emergency connection, then nothing. My phone keeps flashing the android screen, seeming to restart. I could get a shell up, but I can't get root.

    you arent supposed o extract the cab file put it in a folder on your C:\ drive labeled VS740. extract the lg-utils zip to that folder make sure the cab file is in there as well. and run the kp500-utils-en.exe in compatibility mode for windows xp sp2 and as admin then try the rest of the instructions

    the 107mb should be the cab file. if it has a different extension change it to .cab and inside that file it should have a dll file a wdh file and a wdb file. and it looks like you may not have lg mobile updater installed so you need to install that as well

    open your c:\vs740 folder and make sure you can see the file extension like .zip or cab or exe and press print screen open Paint press ctrl+v and then save that file and upload here as a screen shot so i can see what your folder looks like

    Alright, I went through all of these steps without bricking my phone (but it's pretty close). It flashed v6 to my phone just fine, and all was well until it hit the "Android" screen when it started to reboot. Since it's not stuck on LG, I'm not totally panicking, but it's been showing me "Android" for nearly 45 minutes now. I have disconnected it from the USB cable, removed the battery, attempted a hard reset, and it only boots up normally, then once again gets stuck on the "Android" screen.

    In order to do a hard reset, I used the button combinations vol down+send+end and vol down+send+home+end after reading through a thread another user posted on here.

    I don't know if disconnecting the USB cable made it worse, or if I have been using the wrong button combinations (or somehow not holding the buttons down correctly) but up until the android screen it was running fine. I gave it half an hour before I disconnected the USB.

    Any suggestions?

    EDIT: Never mind, booted into recovery, wiped data, and rebooted again. I'm setting it up again. I'll edit again if I have any other problems.

    Total noob here. I have flashed to V9 per your instructions in an attempt to repair a broken market due to uninstalling the wrong apps. I now have no market app and am not sure how to proceed. Should I attempt to install a market.apk and if so where should i get it and is there anything else that needs to be installed? Should I try to flash back to V6 and then OTA update to V8? I can get root with UniversalAndroot and have Titanium Backup to reinstall user apps but don't know what to do about market? Any ideas?

    Oh btw my home and menu buttons are not working on the front of the phone or on the slide out keyboard

  21. p3tr01d

    p3tr01d Member

    I do not have a custom recovery installed. just the stock rom. I power cycled and got home and menu button functions back but still no market. will try back to V6 and let u know

  23. death2all110

    death2all110 VIP Member VIP Member

    No. i doubt it. I really dont think i can help. try a factory reset. Turn off phone Press and hold Vol down+home+end and let go when lg screen appears

    I flashed back to v6 but it hasn't updated to v8. I tried *#*#CHECKIN#*#* and system updates but it will not update to V8.

    Thats because they released the VZB update. So you may just have to wait to update until it gets pushed to your phone. Everyone should have it pushed to their phone by friday. Are you using a custom recovery?
