    Arrow [HOW TO] Return to Stock V9 Recovery

    Thanks to Drew for this method. Going to pass it on for those that need to get back to stock Sprint.

    Here are the steps necessary to flash the stock v9 recovery image.


    This is for a rooted phone running either ThunderC or Xionia CWMA recoveries:




    1) Download this:
    2) Inside that zip file is a folder called "platform-tools"
    3) Copy that folder to the desktop
    4) Inside the folder you copied to the desktop, there is a file called "v9recovery.img"
    5) Copy v9recovery.img to your sdcard
    6) Turn OFF USB Storage
    7) Open a command prompt (in Windows XP this is Start->Run then type "cmd" (without quotes) then hit enter
    8) In the command prompt, type "cd" (without quotes)
    9) Drag the platform-tools FOLDER from the desktop to the command prompt
    10) Make absolutely sure there is a single space between "cd" and the rest
    11) Hit enter
    12) Type "dir" followed by hitting enter
    13) One of the files listed should be adb.exe
    14) Type "adb shell" and hit enter
    15) When it connects, type "su" if it shows a dollar sign ($) and not a pound(#)
    16) Type "cd /sdcard" and hit enter
    17) Type "ls" and hit enter (that's a lowercase L followed by a lowercase S)
    18) One of the files listed should be v9recovery.img
    19) Type "flash_image recovery /sdcard/v9recovery.img" and hit enter
    20) When that finishes, type "reboot recovery" and hit enter

    Should reboot into LG stock v9 recovery.

    Then you need to get stock ROM: [How-to] Revert to LS670V9, after installing OTA LS670VC/VD, using KP500 (Diag mode)

    or

    Are the newer screen models able to use this? Or will they have issues? Just a thought and cant remember the answer

    I finally got it to detect the device but when I access the adb shell it comes up with a pound symbol (#) instead of the dollar sign. =\

    Would you happen to be running either Shell ROM or Reborn ROM? If so, that's normal.

    Little trouble with this. I could use some help.
    I have followed the directions exactly.....no problems until I put in the last command....
    I get this error.
    "sh: flash_image: command not found"
    I have tried it several times so I know that I am inputting it correctly.....Any ideas what I'm doing wrong?
    And yes the flash v9recovery file is on my sdcard where it should be.

    In a command line or terminal on phone you could download the zip attached extract the file from it to sdcard then run the following and should have stock recovery.Make sure you have the recovery and flash_image file on root of sd..
    Code:
    # mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
    
    # cat /sdcard/flash_image > /system/bin/flash_image
    
    # chmod 755 /system/bin/flash_image
    
    # mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
    
    # flash_image recovery /sdcard/v9recovery.img
    
    # reboot recovery

    Some thing has gone TERRIBLY wrong.

    I followed your directions and had complete success at each point.

    I flashed the v9recovery.img, and when finished I typed reboot recovery.

    The phone rebooted and goes to a blank screen. Windows xp sees GOOGLE Mass storage device and generic volume "f"...but I can't access volume "f" .

    If I repeat the cmd process when I type adb shell it says:

    -exec ' /system/bin/sh' failed: no such file or directory <2>

    So now what????

    You must have newer LCD screen which means V9 recovery has black screen. The display drivers in V9 are for older optimus phones. Android screencast is what you need.

    Smile Re: [HOW TO] Return to Stock V9 Recovery [SOLVED]

    Thank you for the quick reply, I couldn't use screencast as it needs to be launched from the phone (which I cant see).

    I managed to get it all straightened out anyway though.

    I downloaded the ZVD.cab and renamed everything accordingly. Then I simply went through the steps again and I got a working screen again.

    Then the usual stuff: root,xionia recovery, make backup, load new rom, tweak, make new rom backup, DONE...lol

    ALL the information that allowed me to get EVERYTHING working again came from this thread:

    ***[How-to] Revert to LS670V9, after installing OTA LS670VC/VD, using KP500 (Diag mode)

    Just thought I'd include it in case anyone else needs it.
