[LG Optimus Black] N00BY0815:
I made this thread in order to discuss possibilities of how to root the latest software for our phone. It's about v20N mainly. Let's try to keep this one clean and root our phone ;)

You can already find a procedure for V20B here: Root V20b

FIND ROOT FOR V20n HERE Root V20N

Methods tried and fail:

http://www.unlockroot.com/? not clear yet...

unlockroot (not clear yet...)

Gingerbreak different Versions

SuperOneClick 2.3.3

Blackjack 1.2.0

adb push wont work for me at least...

SoC

z4root

vipermod

thrill

doomlord all version

androidnerds.net/2011/10/08/lg-esteem-oneclickroot-now-ready/

Gingersnap Root Itility tells me it succeeded, but root still aint present...

adding that ratc exploit

Working so far:

adb install *.apk

According to Redpik: "Superoneclick 2.3.3 was able to copy busybox into /system/tmp but couldn't find the glitch."

Local rooting, since some apps like rootchecker show our phone is rooted

As it seems, Unlockroot also works for some with v20n, maybe even others, if they disable the LGE Modem.

I somehow managed to root it by aproxymately doing this:

Enable debugging mode

Disable LGE Modem

Plug in USB cable

open UnlockRoot

click root

REBOOT and DONE!

-edited-, cause it didnt work with the method posted before.

Kill adb server
Starting adb server...
Get online devices
Try LGE shell rooting...
push file to device : rootutility
chmod file 755 rootutility
Restarting debug mode...
Waiting for debug mode...
push file to device : busybox
push file to device : su
chmod file 755 busybox
push file to device : Superuser.apk
Rooting, please wait...
Root Succeed!
Root finished!

Noone could reproduce the root till now, but I'll keep on trying.

It somehow worked and I made a nandroid of this. Link below...

How to flash it:

1. unzip the file

2. Take the whole folder and put it on ur SD card under sdcard/clockworkmod/backup/

3. You need a rooted phone where you can access recovery by either using a app like RomManager or by adb shell via: adb reboot recovery (thnx to gabwerkz, since I didnt know)

4. reboot to recovery either via command or APP

5. choose backup and restore

6. choose restore

7. choose the foldername u just put onto ur SD card

alternatively (PRO USERS ONLY)

go till step 5

and then choose whatever you wanna have

Thats it so far. Maybe a MOD can take this thread and moderate it, since I hardly have time (but if possible also gimme right to edit it).

You also will find the solution in this post, as soon as any1 made it ;)

Seems like I made it ;)

here is the link to a complete NANDROID BACKUP

THIS IS NOT A FLASHABLE ZIP! UNPACK IT AND FOLLOW GUIDE ABOVE!

IF you want a flashable zip, pls go to Redy's thread, he repacked and added some tweaks ;)

Big thanks to Redy!!

Or use Zeus ROM by huexxx: http://xdaforums.com/showthread.php?t=1454274

DO A FACTORY RESET AFTER FLASHING, WILL FIX SOME PROBLEMS!

Mick2K suggested me to post, that you should install busybox after the procedure and update su binaries, so that everything works fine.
