If that is true, can I then Flash this Rom onto my Phone? Thanks for the help!

It probably won't brick your phone, but you will likely have data troubles because the NANDROID backup doesn't (ie can't) restore the baseband radio. The only way to get the proper baseband is to use the LG flash tool. If you were already on VD baseband then you could use a NANDROID VD backup to restore from and stuff should work.

If you are typing your post correctly, you are missing a space between the "mount" and the "-o".

I would suggest you just cut/paste (skipping the # and $ signs at the beginning of the line)

Well Darn, is there anyway I can use the LG tool?

If you have access to a windows installation, you can use the revert thread in my signature and substitute whichever version you want to revert to from the Reference section (the instructions default to V9, but you can go directly to V8, V9, VC, or VD)

**HawkFish707** · 09-27-2011, 08:03 PM

Okay, cool. I have access to a windows Machine, and I can install the tool. But I'm at V9 so I wouldn't be Reverting, I need to update to VD, does the tool do that?

If you want to end up at VH, just make sure you have stock V9 recovery and you are fine to run through the Rooting ZVH instructions. Actually as part of those instructions, if you follow every step, it'll make sure you have V9 recovery.

You do *not* need to go to ZVD just to upgrade to ZVH. ZVH updater will run fine with ZV9 install. This is not necessarily the case for all Optimus updates, just the ZVH one.

Bump

Completely revamped instructions to make super simple.

**Jean-Marie** · 10-08-2011, 04:13 PM

Huh? Where?

**sfhub** · 10-08-2011, 04:27 PM

First post, no more use of KP500, far simplified return to stock Recovery.

**em072205** · 10-09-2011, 11:44 AM

Running into a problem and not sure what to do. I followed the steps required and the part where it says 3-7 minutes will boot up into android...however, it never finished booting. It is stuck on the Android flash screen and keeps going in a loop.

Finally got it to work!! I am not sure what happened, but I took my sd card out and was able to get into recovery to do a reset. Now it boots up. Whew..lol

Will this work if you are running ZVH also?

**sfhub** · 10-09-2011, 12:34 PM

The only requirement is you have stock recovery.

You are my hero

**vfr_geek** · 11-29-2011, 11:19 PM

On the install of stock recovery I am receiving the error for out of space... I am using the commands cd /sdcard/000root , then the /system command as is written on the instruction. Any help would be appreciated thanks

If you have Xionia CWMA recovery, try doing the shortcut.

If not, then could you type

busybox df -k

and

ls -l /system/bin/flash*

It sounds like your /system is full for some reason.

**vfr_geek** · 12-03-2011, 08:03 PM

It might be. Havent messed with it yet but I plan on trting it now. So after busybox df -k I put ls -l/system/bin/flash install_vd.sh???

busybox df -k

will tell you how much space is available in your various partitions

ls -l /system/bin/flash*

will tell you the file size of /system/bin/flash_image (that's an asterisk after the "H" in flash)

I want to figure out where your problem is originating from.

**vfr_geek** · 12-05-2011, 01:20 AM

the busy box keeps saying it doesnt work =o\ neither does the df -h command i used to know of back on the hero... as far as the ls -l command it pulls up-rwxr-xr-x root root 9640 2011-12-04 23:05 flash_image when i do the regular df command it pulls up the partitions available and my system is 162304k total and 128488k used so i dunno... i don't have a recovery right now either since trying to flash the stock one it just stays black screen.

**sfhub** · 12-05-2011, 02:10 AM

Your flash_image looks ok.

The only other thing that could be going wrong is you have a corrupted recovery image.

Can you type the following and copy/paste the full output

cd /sdcard/000root
ls -l

Also can you post the exact command you typed in adb shell to flash the stock recovery. Cut and paste also that also, preferably after you run it, along with error message. I want to make sure there are no errors there, so telling me you typed it as in the instructions wouldn't be helpful.

Hi, I've followed the steps, and got an unrooted stock (yay, this allowed my 3g to start working again after a phone swap via Sprint). Only problem is, now when I try to root via Gingersnap OR long Gingerbreak instructions, everything seems to work ok, check root says I am rooted, BUT I got to the adb shell and su and get "Permission denied" message. Seems rooted, but I can't get root. Is there a known problem with this method with re-rooting, or did I mess something up?

**DaMadPoet** · 12-05-2011, 08:19 AM

Nevermind. It has been so long, I forgot that I have to be watching the screen and grant permission. I'm an *****.

Rooted now

whats the command used to copy and paste the full log?? is it just ctrl+c and ctrl+v? and I will get that soon as I can don't really have that much time to mess with it. just trying to unroot so I can trade it in and get some cash for it.

If you are using cmd prompt, press [alt][space] to get the menu, then Edit->Mark, mark the text using point and click, then Edit->Copy
