    Default [Guide] How to install a custom recovery and rom

    This guide is very straight forward. I assume you have basic computer knowledge. I will not be holding your hand to much. If you do not know how to open and extract a zip file or follow simple instructions, then please leave now. I take zero responsibility for you bricking your phone. I thank all the members of this forum. We truly have some great developers and contributers.

    Downloads:




    Note: If you have already rooted your Optimus, you can skip steps 1-6.

    Install custom recovery and make a nandroid backup:
    1. Enable USB Debugging. Menu > Settings > Applications > Development > check mark USB debugging
    2. Extract superoneclick to it's own folder and extract the Optimus V Drivers.
    3. Install 1.exe, then 2.exe, then 3.exe. If it ask you to plug in your phone to the usb cable, then do so. Reboot your PC.
    4. Open SuperOneClick.exe
    5. Make sure psneuter exploit is checked and click shell root.
    6. It should tell you that you have temp root after a few seconds. Do not continue if you do not get temp root!
    7. Download a custom recovery of your choice. I like . You can read about recoveries in the Reference Guide. Extract .
    8. Put the recovery.img and flash_image on your sd card (root of the sd card)
    9. Now we will open a adb shell. Open "/superoneclick/ADB" folder. Shift+Right Click in a open area and choose "Open command window here". (I know that trick works in Windows 7, not sure about other Operating systems.)
    10. Paste the following commands into the command prompt one by one. Do not copy the quotes.
      adb remount (It should say remount succeeded.)
      adb shell
      cat /sdcard/flash_image > /system/bin/flash_image
      chmod 755 /system/bin/flash_image
      flash_image recovery /sdcard/recovery.img
      reboot recovery
    11. In your chosen recovery, make a Nandroid backup.


    Note: Now that you have a custom recovery, never EVER, EVER do a factory reset. (Settings/Privacy/Factory Data Reset) You have been warned.

    Install a custom rom:
    Read this forum. There are several custom rom threads. Some based on 2.2.1, and some based on 2.3.3. If you are unsure, have a look at the Reference Guide to learn more about the ROMs. As always, the individual rom thread's will have most of the info. After you have found a rom you would like to try, place the rom.zip on the root of sd card. Then you need to flash via recovery. It is a good idea to wipe everything (besides your sd card) before you install a new rom. See your chosen ROMs thread for specific instructions on installing your rom. This is just general overview.

    Boot into recovery:
    Power off your phone (no usb cables or power supply connected)
    Hold Home+Volume Down+Power till LG screen disappears

    Nice! Added to the reference guide. One suggestion though, I'd remove the comment from step 10 or change its color. People tend to blindly copy and paste.

    Or put it on a separate line and prepend "::" to make it a comment (ignored by the shell). Too bad the Windows shell doesn't allow inline comments like bash and other UNIX shells do.

    But yeah, nice guide! I'm still waiting for the Bluetooth kinks to be worked out in aospMod before I flash a custom ROM, as I frequently have to use a Bluetooth headset in the car. But guides like this give me a lot of reassurance that I'm most likely not going to break anything irreparably.

    Default Re: [Guide] How to install a custom recovery and rom

    Put the recovery.img and flash_image on your sd card (root of the sd card)
    Where do I find this file? "recovery.img" it is not in the flash_image.zip archive.

    UPDATE: i have downloaded a lot of various files based on different sets of instructions and wind up confused.
    I have two files I found somewhere that appear to be img files with the following names. I don't know what the difference is.
    Do I rename one of these to "recovery.img" and which one?
    * recovery-RA-GNM-thunderc-s-1.1.0.img
    * recovery-thunderc-v-1.2.o-GNM.img

    Below is my specific phone. Any help in determining the correct steps for THIS phone to /root the device so I can update it please let me know. I found conflicting information and don't want to wind up bricking my first attempt.

    Thanks.

    Model: VM670
    Android: 2.2.2

    Step 1- Wait. The first load of a new rom can take a while.
    Step 2- As long as you have a backup made, you can pull the battery, then press and hold Menu, Volume Down, and then Power until the recovery menu comes up. From there, you should be able to restore your nandroid OR install a rom from zip.

    OK, so which recovery do you have installed? And do you still have the ROM you attempted to load on your SD card? If so, you can just try flashing again, or you may be able to mount your SD card from recovery. In that case, you could load whatever ROM you want even though you only have recovery.

    Mods should probably archive this thread as well. It has to have been replaced with a better way by now
