    Default update.zip not installing

    1) Plug phone into PC
    2) Enable USB Mass Storage
    3) Download and place it in the root of the USB Device/SDCard as "update.zip" (renaming it is important!)
    4) run the following from cmd prompt: "adb reboot recovery"
    5) You are now at LG's dark-blue recovery screen (should only be 4 options, if not STOP HERE)

    6) Select the option with "update.zip"
    7) follow instructions on screen (VERY IMPORTANT)

    You now have V9 Radio/Baseband and V9 stock update. You can delete the update.zip from your SDCard when you are back into Android.


    i followed all instructions and now im back to stock... but when i try to install the update.zip it says "
    -- Install from sdcard...
    Finding update package...
    Opening update package...
    Verifying update package...
    E:Failed to open /sdcard/update.zip (no such file or directory)
    E:signature Verification failed
    Installation aborted.
    "

    but i named it update.zip and placed it on the root of my sdcard... can someone help me?

    That's where I got with mine when I gave up and decided to flash my original backup instead of the one in this thread. Shoot me a pm and i can give you a copy of my clean backup that is working for me. It is the v9

    I downloaded the v9 stock recovery.img from OPs web site [God bless Zefie] and did a
    #flash_image recovery recovery.img. Now I have a original config.

    Now the question is how to take a nand back up or create update.zip of what I have with out custom recovery. Just in case I need in future to get back to original setup?

    I too am stuck at the exact same spot Appears to be back to stock though, phone isn't activated so I cant see if it wants to run an update or not.

    This is 99.9% STOCK. This returns your phone to the state it was when you opened the box.
    Thank you for this fix, I was stuck in the custom recovery reboot loop with this recovery. So I just followed the steps from there and it fixed my phone.
    Thanks,

    13) Go down to "USB-MS Toggle"
    14) Select "USB-MS Toggle SDCard"
    15) Download my Stock V8 Nandroid Dump
    16) Unzip it into the root of the USB Device/SDCard
    17) Safely remove the USB device using your PC OS.
    18) Press menu to disable USB-MS Toggle.
    19) Press back.
    20) Select "Backup/Restore".
    21) Select "Nand restore".
    22) Select "mem=477M".
    23) Select "BCDMRS12-20101122-1915"
    24) Press menu to confirm.
    25) When the process is complete, DO NOT REBOOT. Nandroid does NOT flash recovery by default, to protect from losing your custom recovery. In this case we WANT to lose it, otherwise we won't be stock, and OTA updates will not work. Therefore we must...

    26) adb shell
    27) mount /sdcard (if this throws an error about "device or resource busy", just ignore it)
    28) cd /sdcard/nandroid/mem=477M/BCDMRS12-20101122-1915
    29) flash_image recovery recovery.img
    30) reboot

    Following the directions to what I would think is to a "T" so to speak...Ive unzip'd the nandroid backup you provided into the root, I see where it went, right next to mine, and when I go to run it, the nandroid restore would fail after a few dots loaded, saying something about nandroid.mobile.

    Any ideas?

    ***UPDATE***

    Just rebooted into recovery again, and now I'm assuming its the LG recovery. A lot of the options have disappeared and I'm confused >_<


    ***UPDATE AGAIN***

    Yeah, so I'm afraid I'm a bit of an *****...When I renamed the file to update.zip, I forgot that I had known file extensions turned off, and I named it update.zip.zip. Retrying.

    ***FINAL UPDATE***

    Hey, sorry for spamming the thread, but I figured it out. I must have gotten a bad download or copy to the phone. I redownloaded it, sent it to the SD card and re-flashed the recovery onto it. I think I'm getting the handle of the Android ecosystem. I'm a big webOS guy sorry

    Anyone else having an issue applying the v9 radio update? getting an error about update.zip not found?


    3) Download the V8 to V9 update and place it in the root of the USB Device/SDCard as "update.zip" (renaming it is important!)

    Soo to all that may have ran into the same issue, simply rename the file to "update" not update.zip , its already a zip file duh soo yeah im all set now, awesome.

    Thanks

    In case this helps anyone.

    The optimus I have came with v9 stock.

    I just wanted to get rid of Sprint ID so the phone wouldn't be stuck on the stupid gray activation screen (requiring the use of voice rec workaround to navigate menus and apps), then keep the stock rom and give it to someone less technical to use.

    rooted with rageagainstthecage

    installed custom recovery partition to create a nandroid backup

    installed titanium backup apk

    in titanium backup, removed sprint id

    Everything was working great, phone booted into a usable state w/o need for extra voice rec shenanigans. I was about the do a ##786 reset then realized that I had installed the custom recovery partition to do the nandroid backup. In hindsight I didn't really need to do that other than to make backups, but it was already done. Didn't want my friend to inadvertently do a reset (or be told by CS to do a reset) and be left with a phone stuck in recovery mode.

    Seemed circuitous to go back to v8 just to upgrade to v9. I decided to just flash the v9 recovery.img. I also wanted to verify the recovery.img was indeed the v9 (OP said it was, but never hurts to verify). Took a backup recovery.img I had and ran checksums against the one in the first post. Yup, exactly the same.

    I proceeded to flash the recovery.img and reboot.

    Then did a ##786 reset.

    formatting DATA
    formatting CACHE
    factory reset
    reboot

    Phone booted into Android home menu w/o the dreaded Sprint ID configuration. The phone was nice and usable with wifi even without activation. Standard resets through android methods like privacy and ##786 worked fine.

    This is on a never activated Optimus S that came with v9 stock.

    Anyway, all this is already implied in the instructions of the first post. Just wanted to share my version of how I used these instructions in case it helps someone else.

    I'm guessing, in theory, if you were happy with your version of ThunderRom and weren't going to flash new ones anytime soon, you could also just flash the v9 recovery.img and restore the ##786 and Privacy reset functionality, though I didn't test this. That would make it safe to hand over to someone less technical.

    I guess I should explain better since I'm was a bit frantic earlier lol.

    So I went into privacy (using Thunderom 1.3) and did a data factory reset. I had no idea it would brick my phone or mess anything up since it was not disabled in the rom.

    Now whenever i reboot, remove the battery, or turn off the phone, I am stuck on the Android System Recovery Screen. This is the Thunderom version, not the LG default version.

    I wouldnt mind installing 1.6, but when I do it still takes me to the Recovery Screen instead of booting android. I make sure to do a data, davik, and cache wipe before I install 1.6. I also have 1.3 zip and after installing i cant get into Android.

    So following the steps on here I am unable to type su on the command prompt because even though my phone can connect with the USB, I cannot get inside android so the SU app wont work.

    I have old nand backups but they wont seem to work when i restore them.. What shall I do?

    Thank you for any help you guys can provide me!

    SO glad I found this guide! but Im having some problems on steps 5 and 6. am I supposed to unzip the recovery kernel and flash_img to my sd card or into the sdk manager tools? Ive tried putting them in both places, and then my next question was when I put in "adb push recovery-RA-GNM-thunderc-s-1.1.0.img /sdcard/" it tells me adb: not found, Ive tried it about 20 times to no avail.

    Is there a way to return to factory default (system wipe/restore) without rooting?

    Basically, I bought a used phone and I want the other guy's stuff cleared out.

    I am currently on V9 running LegoRom. Could I do this?

    1) Nandroid backup my current LegoRom
    2) Do this method to return to stock V8
    3) Do the update to V9
    4) Do the update to VC
    5) Re Root/Flash Recovery
    6) Restore Nandroid of my Lego Rom
    7) Have my old Lego Rom with the new radio

    Please. Can one of you Android gurus make a video for the rest of us? Also, while installing custom recovery, we did a nandroid backup so what is that used for?
    Can we simply not use the custom recover to reload the original factory image and then remove the custom recovery?

    couldn't you just wipe everything, restore a nand backup that you made before switching to a custom rom flash the default kernal, remove the custom recovery and then just use z4root to unroot your phone?

    ADB has to be run directly from the directory where it was installed which on a pc is generally c:/android/platform-tools. If you add that directory to the windows "path" environment variable then you don't have to cd to that directory in order to run adb...otherwise you must be in that directory or the command will not function.
