There is now a rooted stock rom for updating. It is the easiest way. Here is the link:

If you need to use the incremental update for some reason there are two methods below.

Method 1:

Requirements:
*STOCK ZV9 (not a flashed rooted version of stock), that mean no google now.
You will need to revert back via LGNPST
*Root
*The ZVB update
*GooManager App
*Freegee App

Here we go:
1. Revert back to stock
Here is the guide that AdriVelazquez made:

2. Allow your phone to update to ZV9 if it isn't already.

3. Root phone using this method.

4. Install Freegee from the market and unlock and install twrp.

5. Update twrp using the GooManager app.
If you hit the menu button in the app you will see "Install OpenRecoveryScript". That is how you install a recovery with the app.

6. Download the update.

7. Reboot in recovery. Install the update.When you reboot it will ask if you want to fix root. Take a guess on what you hit.

8. Download the updated Freegee app from 3/3/13. The version is 6.0.1. If you use an older version you will get a soft brick. So, make sure your updated.https://play.google.com/store/apps/details?id=edu.shell.freegee

9. Run the Freegee app.



Method 2:

1. Root using zv9 method(you'll have to plug your phone into the computer). Rooting is required to write to the cache folder.

2.Download update and place it in cache. Cache is a folder in the root directory. Rename the file "update.zip" without the quotes.

3.Here you have an option to use OTA Root Keeper if want. It is on the market. This app will let you keep root.

4.Boot into stock recovery. You can use the Quick Boot app. If you reboot the phone but don't go to recovery the update is going to disappear. That is why we recommend using a program to boot into recovery.

5.Once in recovery select Update from cache.

If you have problems with root after the update and you still have the superuser app.
Try this:


Open Super SU. If it says no SU binary installed this what you will need to do. You should still have the files you downloaded to do the ZV9 root. Open a command window in that folder. The folder needs adb and the su file. Type this below. Hit enter after each line.

adb shell mount -o remount,rw /system

adb push su /system/xbin/su

adb shell

chown 0.0 /system/xbin/su

chmod 06755 /system/xbin/su

Exit

adb reboot

I am guessing after booting up to JB it is probably a good idea to do a factory reset?

Yes, he already said he was going to do it tonight or tomorrow. I am sure he already knows what he has to do. He just needs time to get it done.

He really is a jam up guy.

There already is a method by flashing a boot image. But, if you like the KISS method I would just wait

I didn't have to and everything seems to be working flawlessly.

EDIT: I did have to restore root with Rootkeeper once the update was done.

Re: GUIDE: Installing Jelly Bean on Optimus G for the rooted

Will this method work if I'm rotted on stock v9 with locked boot?

From what I've read, as long as it's stock (besides being rooted) it should work. Note: Sounds like build.prop edits are causing some updates to fail, so when I say stock, I mean stock (besides root).

Re: GUIDE: Installing Jelly Bean on Optimus G for the rooted

anyone think they can point me in any type of direction. I'm so pissed right now. I'm stock as can be on zv9 and I'm trying to get the LG drivers. It does not work! I'm using the LG Mobile support tool which blows because it will NOT read my phone for some weird reason. I'm sure I can do everything else on my own for the rest of the "simple" root process but this is stopping me dead in my tracks. please guys any help would be greatly appreciated

Make sure you secure root with root keeper or supersu. Thats what i had to do.

    The updated freegee just hit the market. You can now unlock your bootloader and install a custom recovery.

    Anyone still here?
