    Hey I felt it was a bit hard to follow the directions posted on how to restore your recovery after clockwork or allyRR (custom recovery) on a rooted ally so that ota updates will work correctly.

    -If you are not rooted install a app called astro from the market and install universal androot from your sdcard ( http://androidforums.com/ally-all-things-root/161744-universal-androot-beta.html )

    Anyway, here is my simplified version. It was tested on windows 7 x64 and x86
    props to drellisdee im just restating his work
    (http://androidforums.com/ally-all-things-root/146564-ally-recovery-img-here-custom-roms.html)
    The file links are on his post and elsewhere on the fourm

    -Download-
    android sdk (found on official android site)
    flash-image (needs to be unziped)
    stock_recovery.img (thanks to drellisdee)

    install android sdk to C:\
    install Lg Usbdriver - if needed
    copy flash_image to the root of your sdcard (remember to unzip it)
    copy stock_recovery.img to the root of your sdcard

    run cmd (windows command shell) as administrator by left clicking it

    / cd C:\android\sdk\tools (sdk's tools directory)

    / adb shell

    / $ su

    you should have root # prompt on you phone, allow acess.

    / # mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system

    / # cat /sdcard/flash_image > /system/bin/flash_image

    / # chmod 755 /system/bin/flash_image

    / # mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system

    / # flash_image recovery /sdcard/stock_recovery.img

    / # reboot

    now your done ... wasn't that easy lol

    ...if you wanted to completely revert to a stock 'out of the box' ally flash the lg v6 rom first then fix your recovery second
    thanks to death2all110(http://androidforums.com/ally-all-things-root/166588-how-flash-stock-lg-rom.html)

    Finally i have to recommend flashing first the vzb deodexed and radio rom, then velocity 2, then the new v4 jit oc kernel and install adw launcher and set cpu @ 740mhz for max performance/max stability if you want a rooted ally... personally i used allyRR to achieve this, it personally gives me less trouble than clockworkmod... all of these file can be found on this forum or market.

    Yes they go on sdcard and these commands copy flash_image from sdcard to system/bin.

    Thats because you need to revert to V06 via lg mobile updater to apply an ota update and if you still have custom recovery after downgrade to v06 following guide above to restore stock recovery.

    exactly.... custom recovery is what did it for me... i originally thought the v6 downgrade would flash the stock recovery but i was sadly mistaken. bty thank you drellisdee for you awesome support for the ally.

    That error is common you just need to repeat the adb steps. If the out of memory error continues try rebooting your phone then continue the adb steps.

    Power on the phone by holding SEND+MENU+PWR until you see the LG logo then let go. If you see an android and a exclamtion point then the phone reboots normally. That means you have the stock recovery.

    not really cuz of your custom recovery. you got to install the default one after you flash your stock rom. then you can install an update you get...

    I think if someone would alter rom manager to give you the option to flash an alternative recovery and be able to flash the stock recovery back would be a huge time saving option for this phone!

    mine hasn't either. idk why this fix will not work for me because it worked for me in the past. i had vzb, had problems with apps 2 sd. pushed v6, it wouldnt update and i hated v6 so i pushed v9 lol and updated my radio. im just going to wait for a fix or or just stay the course... bty verizon wont flash anything, i tried that lol and to top it off ally rr wont work for me anymore so im using clockwork with amon ra
