Hello guys I have finally rooted my LG OPTIMUS 3D MAX P725 phone and here are the steps originally from Russian forum 4pda.ru for LG OPTIMUS L5 working on our beloved OPTIMUS 3D MAX.

Working on LG OPTIMUS 3D MAX P720, LG OPTIMUS 3D MAX P725 AND LG OPTIMUS CUBE SU870 ONLY GINGERBREAD

NOTE : I am not held responsible for bricked devices

Follow the given STEPS CAREFULLY :

OFFLINE Root for LG OPTIMUS 3D MAX

1. Download the archive and unpack it (create a folder on desktop named whatever you like):
Root kit http://www.mediafire.com/?fafrhfiu409zy99

2.Download "IS11LG_SystemBackupTest.signed.apk" attached below and copy to root of your phone (internal storage).

xdaforums.com/attachment.php?attachmentid=1272418&d=1345501542

3. On the phone in the "Options -> Security" enable "Unknown sources"
In the "For Developers" enable "Debug on USB"

4. Install "IS11LG_SystemBackupTest.signed.apk"

5. Then open the installed "SystemBackupTest" and not closing
Hold down the power button and reboot the device.

6. You might get BOOTLOOP ,so don't PANIC. Just wait at the LG LOGO.
After 3-4 Minutes on LG LOGO, PRESS Power Button.

7. Connect the usb now ( make sure that usb drivers are already installed ).

7. In the folder you've created «O3DM Rooting Kit» run the file «root.bat»,
wait until the script is executed and the phone will reboot.

8.Then on the phone, open the Google Play Store and you will find "SuperSU"
Upgrade "SuperSU", and then open the program asks updates ... Click OK, to

9.Update SU binary ...

10.Now you have a root-law. You can delete an application «SystemBackupTest» ...

Please see attached photos for proof Enjoy...

IT TOOK MORE TIME TO SEARCH AND TEST AND EDIT THIS METHOD THAN THE TIME YOU WILL TAKE TO JUST " HIT THANKS".

So, Don't forget to " HIT THE THANKS "

Sorry if this is a silly question but.. do you know if it works on V10d?
Let me know if you'd like any further information about my phone - I'm desperate to root this thing, I've spent so many hours trying so many methods.

I clicked the Thanks button before even writing :D

Yep a new ROM would be awesome. I have Bootmanager installed but it's not recognising the device. I had an HTC Desire HD before this, but I rooted that about 2 years ago - maybe I'm forgetting some step like ClockWorkRecovery?

I'll be watching this thread with great interest ;)

Darn.. I tried clockwork recovery backup phone ROM.. and now I think I've bricked it. Stuck at the LG screen. I should have just been patient and happy with the Root access :( Looking for ways to unbrick it.

Oh wow, lol I was about to post about how I solved it. The scary thing was that I couldn't get into recovery mode via the normal method of holding Vol up & Power. So I looked all over, and eventually tried just powering it on by only holding the Vol up button while having the USB cable already inserted. For some reason, that allowed it to enter recovery mode. I'd also noticed that if I tried just booting the phone, each time in my Device Manager it would show the Comm port for a split second before becoming inactive again.

And yeah, once I could see it in S/W Upgrade, I knew I had a window in, and did exactly what you'd said. I just really wanted to stress how important it is to be able to get into the Recovery Mode, in case anyone else gets this frightening situation. I truly thought I'd locked myself out forever. Back to stock, I'll now confidently re-apply your excellent method of obtaining root. ...and wait patiently this time for how to do anything more nifty such as get BootManager working :D

    I run into a problem when trying to run SystemBackupTest i get an error saying "the application systembacuptest (processcom.example.systembackuptest) has stopped unexpectedly. Please try again." I am currently updated to the Official ICS so i think that could be the problem is there an updated apk available for ICS? Thanks.
