     */
    
    Here's those instructions:
    -At this time, this guide is only possible by using either Windows XP or Windows 7 (32bit or 64bit) operating systems.
    -Download all files indicated in red, and double check that all folders and files are in place.
    -Make sure to read the entire guide before starting Step 1!

    1. DOWNLOAD Froyo.zip
    Mirror 1

    2. EXTRACT Froyo.zip to C:\

    2. RUN C:\Froyo\Drivers.bat

    3. Connect your USB cable to your Ally and enable USB Debugging (Settings>Applications>Enable USB Debugging)

    4. Run C:\Froyo\LGVS740\KP500-Utils-En.exe in compatibility mode for Windows XP SP2 and as an Administrator. (Only if you are not running Windows XP)

    5. Choose option J

    6. When prompted for phone model number, type "VS740" and then press enter

    7. When prompted for the cab file, type "VS740ZV6_01.cab" and then press enter (you do not need to specify the location of the cab file)

    8. When prompted for the version, type "VS740ZV6_01" and then press enter.

    9. It should now load the familiar LG Manual Updater screen with a log window below and start reading information from your phone. It will proceed to flash your device.

    If your firewall warns you about trying to access the internet, allow it.

    Your phone will now load a screen that displays the LG and Verizon Wireless logos and says: DOWNLOADING! DO NOT UNPLUG!

    At this point, it is now flashing the update to your phone. This normally takes around 20 minutes to complete. Once complete, your phone will automatically reboot.

    10. RUN C:\Froyo\ADB.bat
    DEVICE MANAGER WILL OPEN AUTOMATICALLY

    11. Expand "ADB Bootloader Device" (Might be listed as "Android!" Under Other Devices)

    12. Right click and choose "Update Driver or Install Driver"

    13. Select "I will choose driver to install"

    14. Navigate to where the Android USB drivers are (eg: C:\android-sdk-windows\google-usb_driver) (If file or directory doesn't exist see Step 2).

    15. Choose "android_winusb.inf" and accept that this is an unsigned driver it should notify you that the driver was successfully updated.
    -It also may state that it can't find suitable driver, if it does simply state you will look yourself and choose "Single ADB Boote Loader" or the like.

    16. We handle the rest!

    Congratulations! You have now successfully updated to Froyo 2.2.1 with a custom recovery and root access! Aren't you proud of yourself?

    ENJOY! :D

    ----------------------------------------------------------------------------------

    For everyone that still has fastboot (this is pretty much anyone running a 2.1 custom rom as well as a few others) savoxis has made a fully automated magical wonder flasher! There are both a windows and linux version:


    To use it:
    Windows


    Linux
    • Download FroyoLiteTux.zip
    • Extract zip to wherever you like
    • Open a Terminal and navigate to the extracted dir (eg cd /home/penguins/Downloads/Froyo/)
    • Type sudo sh froyo.sh

    These tools where made with simplicity in mind, make sure with the tux variant that you run the script as root, you do this by using sudo before the command (in ubuntu) on other distros you can just su before running

    On some distros you may need to set permissions for the script (tux only) do this (as root) by typing chmod +X ./froyo.sh (assuming you are in a terminal in the same directory) Most of you shouldnt need to do this.

    Thank you, thank you, thank you.

    That is all.

    EDIT: Seems you have to rename the update.zip file.

    I know it's not in the instructions but i got into recovery and was going to apply update.zip, but it said no such directory found, meaning it doesn't recognize the OTA name as update.zip

    Can I follow these instructions if I am currently running Velocity .4? My baseband version reads VS740MV7.5210.1013 and right now clockwork recovery is flashed. Thanks. If all goes well I will be donating.

    Trident, there are a few issues:
    #15 should be cd C:\android-sdk-windows\platform-tools (credit: AfterAffekt)
    After #15: Open SDK and go to Available Packages>Google Inc>Google USB Driver Package
    Before #17: Windows 7 users: Upon entering fastboot and letting Windows choose your USB driver you must click on the update and choose SKIP WINDOWS UPDATE
    Vista/XP users: Open the containing folder that has the new google drivers (e.g. google-usb-driver) and find android_winusb.inf
    #23 you need to move the contents of \platform tools into the \tools folder (just so AdbWinApi.dll is in the directory)
    after #28 you should have a disclaimer to not let your phone boot. immediately pull the battery or hold the button combination right away

    That's about it :) only 4 hours to complete too!

    If I've already applied the Froyo update via LGMU can I go back and do this? I don't want to brick another phone 'cause I don't think they will send me another one.

    When I tried to install superuser, it said it couldn't verify. So I toggled verification, then it installed correctly. For those of you who have problems with it.

    To clarify....up until youre at zvc vdersion, it's the same as the old way to flash v06 and recovery right?
  11. Still kinda new to all this, I am currently running the Punisher ROM on my Ally, if I follow the instructions above, what ROM will actually be installed on my Ally?
  12. Trident

    Trident VIP Member VIP Member

    Hmm.. it shouldn't need to be renamed. Anyone else have this issue?

    Yes, you can. You can follow these instructions over any ROM.

    Might as well go ahead and prepare.. you MUST follow these instructions in order to use FroYo ROMs.

    Yes, you are correct.

    The stock ROM FroYo ROM will be installed to your device. Then you will go through the process of rooting your device.
  13. Trident, you may delete after you read, but noticed your location and the your name on here....are you Navy?

    Android 2.2.1. AKA Froyo Rooted.
  15. Trident, you say then go through the process of rooting my device...so just download the superuser and install?
  16. Trident

    Trident VIP Member VIP Member

    Nope, not Navy :)

    It's all in the guide. Only need to download what I specify.
  17. Thanks for all you help Trident, you are the man, I will be donating.

    So what can those of us that jumped the gun and used LGMU do? Is there any way to restarting and do this method?

    You did copy it to the root of your sdcard, right?

    Follow the guide from step one and you'll be well on your way to rooted FroYo.

    Same question; but if i have 2.2.1 with custom rec and su, do i have the same end result? Or Should i restore stock nand and perform this proceedure.

    Well fastboot is broken for you. So if your recovery image every becomes corrupt and you loose root for whatever reason, you're SOL. You should be fine for now though.
  24. when I got to type fastboot -w I get error that fastboot is not recognized
  25. tron101

    tron101 Member

    So all this is to have 2.2 rooted with fastboot enabled? Is fast boot that important cuz ive never had to use it that i know of...
    Or will devs be using fastboot for 2.2 custom roms or something?
