I've made some changes to my previous modification of Lelus rooting method to work on V20 firmware.

All actions is like for old method for V10, except what must patch other .bin file from firmware. For V20B P765 CIS this is LGP765_AP[11].bin.

How to patch:


I've added busybox app from market into rooting procedure because this is important to reinstall busybox applets after rooting.

Good news. That means we can root without unlocking bootloader. Right? Can we have something similar on cmw?

You're right. CMW only by 2ndinit. I've tried 2ndinit CWM for v10 with no success - it starts (keys flashes at boot) but hung on LG logo. Suspect this happens because v20 have new kernel.

Good one angrywolf90 Good for those who dont want to unlock bootloader.
please make proper full-length guide
? I know all the steps. But the image is not very clear? attach GIF image inside zip file. XDA reduces image size and also reduces quality of images.

AREMCEE's "Rooting JB" method is more easy and faster, for People with already Unlocked Bootloader or who want to unlock bootloader. They dont need to edit bin and flash. just push CWM in fastboot mode and use flashable root file.

I don't have much free time for this right now. Steps exactly same as guide for v10, except file to patch and text to change.
Image I've attached in zip.

Surely CWM method more simpler, but not for people, who want to keep their warranty for phone. And on 4PDA.RU some peoples complain what they unable to get in fastboot mode to unlock bootloader...

Sorry for off-topic, but I am responding to your information.

Mostly its drivers issue. Phone is not to blame. LG USB drivers include drivers for both ADB and FASTBOOT mode.

I think for unlocking you dont need fastboot mode. Actually "adb reboot oem-unlock" this command is given in ADB mode and it starts fastboot mode, which then asks user to just press VOL+ key for unlocking. Now I dont understand why they are not able to put phone in ADB mode and not able to shoot this ADB command?

Thanks for the IMAGE, its much clear and I have made small FILE WITH FEW PERFECT EDITED LINES to paste in said BIN file with the help of any HEX EDITOR. Should be pasted in overwrite mode of cursor.

It's not a drivers case. Phone is just reboot in responce to "adb reboot oem-unlock" command. No matter to which drivers installed on your system (And what if I've see such thing on my Linux machine? Which drivers you suggest to install? Phone just reboots and thats all. Sad but true.)

With my HEX editor it can't be done like this (yes, I'm old fart who don't want to use some new cool modern tools ), your file much better if user know how to deal with it.

I dont know what to say but it worked for everyone here, except very few people who may be not more familiar with basic terms and are less experienced.

Few weeks back (4 mar) I made this simple and small guide to EDIT BIN file, but almost everyone overlooked.

http://forum.xda-developers.com/show...5&postcount=47

If read with patience it clearly explains how to edit (paste) bin file.

Please have a look. The link was also given in OP of same thread, but unfortunately it was forgotten by all. I think I should have made it in new thread so some of the pals might have noticed it.

Just for the support of this thread I would like to say that, this attached patch bin file and this small guide will be helpful to make your own HEX EDITED BIN FILE for rooting Jelly Bean on L9.
