[Q] LG Optimus 3D V20B cant root

---

Hi i know they have developed a root app for V20b but i keep on getting some corrupt installation stuffs. How do i root it?

What is exactly the problem that you can't root?

Can you give the following info?

1. What is the software u used to root it? This?
2. Is your phone in usb debug mode?
3. Do you have the latest LG drivers?
4. Did you also tried other methods to root that maybe damaged some files. (set phone to factory default in this case.)

If those are okay but your problem is not solved. Please make some screen shots of your errors.

This is his problem.
Try to uninstall everything you can.

Yeah try recovery then root again.:beer:

Hi I found that megatron script for windows works very well with V20B have not tried it on V21B but apparently it works, all credit to Dan Rosenberg the creator. (I have included the file below)

1. Extract megatron_windows.zip
2. Connect phone via usb and have phone in debug mode
3. Click on the file called "run" once loaded press any key on PC to start the root
4. Phone will restart a few times while installing
5. You have a rooted LG Optimus3d/Thrill
6. THANK YOU Dan Rosenberg the creator

1. Yes that software
2. Yes it is.
3. Yes i used the LG update tool to Install necessary drivers.
4. If i set to factory default, i will be downgraded to V10B i think. I did Superclick before. Is it the problem?

you can backup them but you still need to remove them after. Also i prefer to do a factory reset. Than you are sure you deleted all that's needed.

Only i'm wondering how many apps you installed i got 38 own installed apps and i rooted mine with no problems (v21b).

Edit: a factory default will not downgrade to early versions when you updated by FOTA or LG-Update tool. I bought my phone With v10b (rooted with superoneclick) later i did original update by FOTA to version v10e (Didn't lost root), Later i updated to version v21b. Do almost every month a factory reset and i never downgraded or lost root by doing that. Only all apps/contact/settings are deleted.

I have a similar problem.

tried to root my p920 with superoneclick and gingerbreak and none of them worked. the Superoneclick stoped at rooting device step #7. stayed there for an hour. I dont know the version of my firmwire ( those v10 or v20 stuff) because i dont know how to see it. Info of my p920 is gingerbread 2.3.5.

thks for helping
