I noticed the only thing i needed in the zip was the bat file! After entering "apply update from ADB" all I had to was opening the bat file and I was done :)

Enter recovery by holding VOL Down while turning on the phone.

[LG Optimus 4X HD] kaisersosay:
Thank you for your response iceddeath. I am fully aware this forum is about rooting and i did mention that i have successfully rooted my phone with the above method however when i read about installing cwm it says you must have root and unlock. I assumed from what i read that the root proccess would infact also unlock the phone so i politely asked if i was missing a step hoping someone may point me in the right direction. Unfortunately your response pointed me in no direction so if anyone could clarify as to how unlock is possible i would be very grateful.

I'm not being funny but was unsure of the context of your response. I couldn't be sure if you just assumed that this issue is really simple or if you were maybe being a little arrogant?

A simple correction

I first of all Thank the user for the tutorial and files. But I am writing for few noobs like me who couldnt figure this out in first try. Couldnt get help here without getting a deafhear to bull****s so figured this out myself. There is no need for adb driver (skipped downloading 400+mb of google SDK). Just extract the folder root on your windows drive where your OS is installed. In most cases C drive. After that you follow steps 2-3 and then run the root.bat and it will successfully install root on your phone. Cheers.

[LG Optimus 4X HD] RuedasLocas:
Just reboot into recovery (battery on, press vol-&power button)

Select "Apply update from ADB" and press power button to confirm.

Connect the phone to the PC.

Double-click ROOT.BAT

Wait untill the phone finish the install and reboot.

Forget the 1st step.

thanks all. is factory reset required for this root? like so in V10 roms?

Is it possible to change su management app from SuperUser to SuperSU? how to do so?
[LG Optimus 4X HD] @non4:
Re: [Tutorial / tool] [official 4.1] [do not downgrade] [ROOT] ZeRospot made ​​a key

Factory reset isnt even required in v10! Just boot into recovery, select install update from adb then run the file named "root" in the folder. As for changing superuser, just install supersu and update the binary through it, uninstall superuser completely though or you will have major clashing between the two

Sent from my rooted and beanified P880
[LG Optimus 4X HD] :
Theres many V10 threads that says factory reset is a must after root, this is one of them. Sometimes people would ask if factory reset was done before complaining about battery drain.

Btw is supersu better than superuser? Im lost at this.
[LG Optimus 4X HD] RuedasLocas:
Wa just a kind way too say that is useless to try uninstall Superuser after instal SuperSU.

Even because you won't find Superuser to un-install (after SuperSU install...). :P

I don't know if one is better than other, I'm just used with SuperSU. I find it more "flexible".
[LG Optimus 4X HD] :
me too. well im less pro-active to do the swap since things SEEMS to be fine except monitoring SuperUser now and see if it actually consumes more battery than before.

is reset after root still recommanded? pls no im lazy to do it:laugh:
[LG Optimus 4X HD] RuedasLocas:
No factory reset required (I think... I didn't.)

Superuser is "injected" only thru adb soo, no other files are used like the first methode where we need to install a app to allow root injection.

Only thing I made after root and froze/un-install un-wanted apps, was clean Dalvik-cache.

[LG Optimus 4X HD] @non4:
Re: [Tutorial / tool] [official 4.1] [do not downgrade] [ROOT] ZeRospot made ​​a key

Easiest way is to flash your kdz again, you can keep all your data but it should remove root from the system

Sent from my rooted P880
[LG Optimus 4X HD] RuedasLocas:
With Superuser I don't know cause first thing I do after root is change it for SuperSU.

If you do the same and choose to install SuperSU in system ( I think you need Pro to be able to), Superuser will be un-installed, you'll have only SuperSU. SuperSU have the option to "Remove ROOT completly".
[LG Optimus 4X HD] fatality911:
Where do i get SuperSu ? from playstore? I just need a fast way to un-root If i ever need to fix it so I dont have warranty Voided
[LG Optimus 4X HD] @non4:
Re: [Tutorial / tool] [official 4.1] [do not downgrade] [ROOT] ZeRospot made ​​a key

If it's warranty you're worried about you MUST flash official rom of your country, root will automatically be removed and they won't be able to tell

Sent from my rooted P880
[LG Optimus 4X HD] RuedasLocas:
Hummmm... about warranty...

Before I unlock bootloader, I couldn't see the "unlock state - unlock" in SW upgrade screen.

Now it's enough to be in EUR V20A or HK V20B to see it, soo... if LG flash the firmware to V20A or other like it, will see it too...

Unless the phone is completly bricked after unlock they're able to know it. And to unlock it ROOT access is required, soo... 2+2=4

They're not stupid also :confused:

I don't care about mine but, if there are people who cares, think twice!!!
[LG Optimus 4X HD] @non4:
Re: [Tutorial / tool] [official 4.1] [do not downgrade] [ROOT] ZeRospot made ​​a key

a bit slow, please help

Could you please explain, step by step, how did you do that. I've followed your instructions (IIRC) for rooting with 10h and SuperSU, BusyBox combo, and now I see these instructions for the new firmware and I don't understand exactly which steps to use from the guide the OP posted in this thread and which ones to follow from your "tutorial" to achieve root and supersu (and busybox).

Thanks in advance :cowboy:
[LG Optimus 4X HD] @ndrius:
How to install busybox? Via gogle play or adb? Which version?

Thx
[LG Optimus 4X HD] RuedasLocas:
First you need root access, follow the OP tutorial. Open Superuser to make it usable.

If you preffer SuperSU instead of Superuser:

Download SuperSU from Google Store, whatever... install it.

Open SuperSU and give permition when Superuser ask.

After SuperSU update binary go to settings and choose "Install SuperSU in /system" (I don't know if you need SuperSU Pro for that).

The phone will reboot and Superuser will be gone, now you'll have only SuperSU.

If you want BusyBox just go to the Store, download it from there and install it.
[LG Optimus 4X HD] Skyfall6:
Hi guys, please help!! I flashed the leaked V20a before and I used this method to root my device successfully, after that I just deleted some bloatwares, then i unroot again use supersu option "completely unroot" or something like that, but today i flashed the official eu open firmware and I cant root again with it and i flash back to Leaked version again and still cant:( I hold vol down and power button and it took two boot to go to recovery menu and i double click the root bat file, there is nothing happening, i tried more than 10 times and with adb driver installed, so please can you help me with that?? THANK YOU in advance!!
[LG Optimus 4X HD] RuedasLocas:
Turn OFF your device, take out the battery, wait 30 sec. and put it back.

Vol- and Power button to get in recovery mode, try it now.

One more thing, be sure that "windows enabler" is not running.
[LG Optimus 4X HD] Skyfall6:
Hi, First thanks for your reply, I did as you told and still failed. i noticed that when i press vol down and power button, the lg logo have to reboot once more to enter recovery mood, before it was only one time, i think something mysteriously changed since last time tempting unroot.....
[LG Optimus 4X HD] RuedasLocas:
If you're having problems better to reflash using LGFlash Tool. Will delete all data from internal memory, factory reset.

Maybe you want to keep apps and settings but, changing between versions without it is not very wise...
[LG Optimus 4X HD] Skyfall6:
Ok, Thank you! I am thinking to reinstall with the V20b HK version, is it wise to change to V20b?? performance wise is better? I am always flash the roms with LG flash tools and i always kept all the apps and setting afterward, before I flashed back to leaked V20a and i entered the recovery mode and did a cache partition and data swap, is this could be the problem?? so what should I do this time first before flashing?

[LG Optimus 4X HD] Wannabezz:

[LG Optimus 4X HD] RuedasLocas:
If you use the LGFlash Tool, its impossible to keep all apps and settings.

The program format the partitions and in the end runs a factory reset.

Be sure that you're using the right tool.

If you have a backup that you use after flash, remember:

-Backups from different versions might not work 100%.
[LG Optimus 4X HD] Skyfall6:
ohh I meant with LG Update Tool, sorry for that..

You can download the "kdz-update" folder again, might be corrupted somehow...

reinstall "msxmi", run "windows enabler" and turn it on.

With no phone connected, run the LGFlash Tool, see if all the ports are red.

If it doesn't work, and once that you already had problems with other tools, probably will be

better for you to re-instal your PC OS...

[LG Optimus 4X HD] Neural_oD:
To all of those - battling rooting on the 20a official version........ I had the same problem - that nothing happened after following the instructions...- I was following post #46 - the "easy" method. Nothing happened with me - tried it about three times. What I noticed that in device manager, my phone came up as an unknown device. I had the kdz-update file already - you can see it in this post: http://xdaforums.com/showthread.php?t=2179126&highlight=roll+back on post #7. I then ran the B2CAppSetup.exe found in that folder. I then changed my country in "Options & Help" to UK - as I'm from South Africa - and the phone is not released here. Once I chose UK, I went to "Install USB Driver" then scrolled down to phone - P880, and installed the drivers.

Once this is done - then follow the instructions from Post #46 - it should work now :fingers-crossed:

Please remember that you have to extract the rar file, then you'll see the root.bat and other files :D

No I try to do wipe data/recovery, and I always have root !

Thats why I wrote 99%...

Before in ICS device used to kept root. Now, on JB, everytime I factory reset or flash, SuperSU remains but without binary installed.

I always need to do the root procedure and update binary in SuperSU...

Maybe keeping Superuser, instead of change to SuperSU, helps to keep root... never tried.
