Care to elaborate? Just saying I'm wrong does not make it so.
[LG Optimus Black] N00BY0815:
Maybe the NOT clean method mentioned here is the key, since I did the same, I had a rooted version of Froyo, installed Update via B2C, all apps remained on the phone and probably opened a bughole like this... Since probably the SuperUser.apk and su binary remain on the phone. But I am just guessing, try it if you want, I bet it then should also work with Unlock Root, instead of SuperOneClick. But that's it from me, for today ;)
[LG Optimus Black] Kshysiek:
OK:) I just only reported that this method worked at the specific V20N PL rom (originally flashed by LGMU) and ten minutes later another guy (with exactly the same rom version) get root by the same method. And anyone can try on theirs own rom. Maybe it could help someone:)

Good Luck!
[LG Optimus Black] adxgrave:
So we need to confirm one thing just to be sure, does your phone already rooted before you upgrade to Gingerbread?
[LG Optimus Black] Kshysiek:
Yes i had rooted Froyo like everyone I think, but I flashed to Gingerbread in emergency/safe mode and I lost everything. I also did wipe after flashing so from root nothing has been. So my Gingerbread at start was completely new- factory reset and definitely no rooted.
[LG Optimus Black] mpsalmeida:
Have someone tried Unlock Root?

On the web site, says that is possible to your device and GB version.

http://unlockroot.com/unlockroot.php
[LG Optimus Black] mil_house:
MSPALMEIDA i was try dont work!

But i this forum all working toghther so if you find any thing try for your self PLEASE!
[LG Optimus Black] mpsalmeida:
Sorry, but I don't have GB on my phone, only Froyo. Because of this, I have asked if someone tried.
[LG Optimus Black] adxgrave:
Can you repeat the process? Backup your current rom with cwm, reflash to froyo, root it, update to GB, enter hidden menu, from there format sdcard and do factory reset, then try root it using your newly found magic. Let's see how it goes.
[LG Optimus Black] kostas_thess:
Finally There is any news about rooting the 2.3.4 ?
[LG Optimus Black] Kshysiek:
No I can't. I don't want to risk, and I don't want to at all. I wrote what method worked with my phone, and anyone can try it yourself. It's all.
[LG Optimus Black] adxgrave:
Lol. Come on. There's no risk. Well, maybe a little but you've your rooted gb backup with cwm. You can flash it back anytime. Besides, it's a good practice to backup your hard to get rooted gb. Savvy?
[LG Optimus Black] Kshysiek:
I don't want to wipe, waste my time and I don't want to at all. This won't nothing change. Like I said anyone can tray it yourself.

Does anyone know if i can give u rights to mod the first post? If not could any moderator take this into his hands and always add latest tried and failed attempts? since I gotta study, because I have a test tomorrow and the following weeks... Sorry, but I'll try ;)

Updated it till page 2. Hope I didnt miss any method...
[LG Optimus Black] knzo:
dxdiag asked me in google talk if I had any ideas on this, so here's a summary of what I know:

1. Use a tool like ZergRush

Acquiring root is basically 2 steps: 1. Get into the ramdisk and change the ro.secure flag on default.prop. This will give you su shell access. 2. Inject on system partition the su binary and superuser application.

ZergRush has the most updated binary for exploiting and reaching ro.secure. If it doesn't work, I doubt any other will, including SuperOneClick shell root.

Make sure to follow all the instructions: you need to enable "unknown sources" and "usb debugging".

2. Flash a recovery through fastboot and then just flash superuser binary and app.

Can't be done on P970.

3. Grab the KDZ, unpack and convert it into a flashable package. Edit default.prop and add superuser binary and app. Flash via recovery.

Can't be done on P970 because the KDZ has a WDB inside and we miss the file with partition information.

So as you can see, there's not much to do.

Just roll back and flash another rootable KDZ or wait for a new exploit to come.
[LG Optimus Black] N00BY0815:
hey knzo would a pull help u? for partition information or anything? ;) Thanks anyway, hope we get to root it soon ...

And another idea, how about making a flashable zip or whatever and root our phone this way, do u think this could be possible?
[LG Optimus Black] timvdhoorn:
did you tried this one? Gingersnap Root Itility
[LG Optimus Black] dxdiag32:
it's stay "executing exploit",so i don't think it could work:(
[LG Optimus Black] N00BY0815:
Is there no way to flash anything via KDZUpdater or something similar? to at least get recovery back?
[LG Optimus Black] Ilko:
you can add that ratc exploit doesn't work too (just tried)

it runs but the system seems to be unmountable. I've checked mounts method with the cat cmd, and it didn't changed from froyo to gb. So, unfortunately any of my known exploits don't work. Sounds we have to wait for a new one
[LG Optimus Black] TuggSpeedman:
come on brainiacs, make the root work! :D
[LG Optimus Black] Sobralobo:
EDIT : Hum... sorry I must have been tired, I thought I have sent a pm. Forget this post.
[LG Optimus Black] N00BY0815:
Don't know if it has any use for us, but I just found out that if u are in secret menu, 3845#*970# u can select certain things about USB connection like AP CP USB switching and Port Settings. Maybe we can use this for our pupose... I already could install the driver from this guide like this: http://xdaforums.com/showthread.php?t=1327599

But I cant get any further, but maybe a more skilled person can :D And yes now I know NV drivers are not for our mobile... ;)
[LG Optimus Black] Ilko:
impossible. 2x hardware is nV based so driving differs from our ob. It's also not the same architecture. It's like trying to install nv drivers on ati stuff
[LG Optimus Black] N00BY0815:
Alright... Thought I might be smart :( gone wrong there as it seems :D But there's definitly recognition of a different USB device. So maybe useful? As far as i remember, I switched to CP Image download mode in AP CP USB Switching.

Still hoping to get it rooted soon ;)
[LG Optimus Black] Ilko:
rightly as you say, different.

I let you know my "attempts list" of rooting on V20N :

exploits :

fre3vo

gingerbreak (bin, not the apk)

psneuter (only work on froyo)

ratc (rageagainstthecage)

zergrush

apps :

gingerbreak

gingersnap (gingerbreak based)

soc 2.3.3

universal androot (exploid based)

z4root (ratc based)

to test : standalone exploid binary (the last one). This could be the last hope :D but this exploit is a source file which needs to be compiled and I don't know how to do that yet
[LG Optimus Black] ambishop:
Anyone try to get zergrush expoit running during boot just as adb shell is available. It would need to be very quick possibly with a custom bat file during boot and just at the exact moment that adb became available
[LG Optimus Black] timvdhoorn:
did someone tried it in safe mode? How to safe mode

(dont know if its working just saying)
[LG Optimus Black] dxdiag32:
the adb is available not means it has root permission
[LG Optimus Black] Orcusen:
Hi, HTCMANIA (SPAIN) we have a user who believes that its root is BLACK.

This is what he did:
[LG Optimus Black] Calvaria:
downloading unlockroot while writing, the newest version is by 13.01.2012. Maybe it will work. Download is slow and will report back.

doesn´t work for me !
[LG Optimus Black] _LIR_:
This version doesn't work too.
[LG Optimus Black] Redpik:
Failed....:mad:
[LG Optimus Black] N00BY0815:
Gotta agree with him, so just ahead and try it yourself, you obviously seem to have the same phone... Kshysiek already did his part in posting a suggestion :)
[LG Optimus Black] catalin.anghel:
It`s working

Yahoooo it`s working:D sorry but it`s working, the metod that Kshysiek use it`s also working on me OB whit first german GB, i just instal unlock root and i insert the data cable in one usb port that i never plugin the phone i enable before that usb debuging and i press root :D and it working, I ussed root check basic and I have a root. But there are 2 things that are comming whit this root it`s have a very small lag and when you restart the phone it`s boot-ing a little heavy.
[LG Optimus Black] N00BY0815:
Root checker proofs nothing, try titanium backup, install it and open it, then you'll see, if you really got root...Root checker told me, I had root, even before I attempted to root it :D
[LG Optimus Black] catalin.anghel:
yes it`s working:)) i just instal titanium backup and it`s working :) so what prof do you want? and be the way i instal also spb shell + crack and that crak it`s not working whit out the root :)) and one more prof that i have root permant it`s that after i root i restart 2 times the phone and after that i ussed root check to see if the root it`s working.
[LG Optimus Black] Kshysiek:
Great! :D And what kind of rom do You have? Did You try Gingerbreak before?
[LG Optimus Black] catalin.anghel:
Stock GB 20N GRJ22 Germany, I update the phone after I saw the post on xda. for root I used your post to do it whit unlock root.
[LG Optimus Black] 1aca:
Sorry man, but if you don't know what constitutes proper proof of root, I'm taking your words with a mountain of salt.
[LG Optimus Black] Kshysiek:
Hmm... I wonder what unites us? I mean why did it only a few people?
[LG Optimus Black] kostas_thess:
already tried with no success ...
[LG Optimus Black] mihaiolimpiu:
Tried it just for the heck of it in a virgin USB port... not working...

I have the same rom as catalin.anghel GRJ22 German 20N Rom
[LG Optimus Black] kostas_thess:
I tryed something else but... I dont know why says rooted

Check screen

this is the prof i have root if there is another program that i can test to see if the root it`s working please tell me
[LG Optimus Black] 1aca:
How about you ask yourself a couple of questions:

What do I need root for?

Do I really need root for that?

Can I do something that requires root with the current state of my ROM?

Until you can answer those questions, rooting your phone is useless, and quite possibly dangerous.
[LG Optimus Black] dharmabm:
That has to be one of the most ridiculous things I have read here! :)
[LG Optimus Black] adxgrave:
Tried it on 20b SEA version 3 times and failed. These 3 test was done from scratch and clean. Use smartflash tool to flash to froyo, format sd, clear userdata and factory reset. Run blackjack to root froyo then upgrade to GB using lgupdater. This process was repeated every time before attempt root.

First try using soc and while soc appeared hang, run blackjack. Failed. Second, tried on different usb port. Failed. Third, remove and reinstall usb driver, still failed.

I give up. Back to clean GB. Damn you LG! LOL.
[LG Optimus Black] catalin.anghel:
For 1aca

First i need root becase i am ussing programs that are need to have root acces one program it's call blocker and outher like avira virus.

I don't think that you need root for simple thing go sell yor OB and buy a 3310 will be good phone for you. But i give a ***** on your opinion i think I'm the only usser that i have root on german GB.Dame I'm good :)))
[LG Optimus Black] 1aca:
Good. Now the only question is do you really have root...

The question whether you have root remains unanswered, but the question whether you have class or any idea about the topic at hand was answered by the above. Thank you.
[LG Optimus Black] stonepws:
No real credentials, no postings etc., to contribute as hardly ever modified my phone apart from rooting my LG P970 once I first received it to allow the execution of certain apps.

However took the opportunity to upgrade to V20N, using LG Mobile Phone Software Update Tool, so I am assuming the upgrade is an unmodified version.

Used unlockroot as outlined by others above, only Unlockroot; no other programs/utilities and it seems 'to work'.. 'to work' is defined in this case as my apps seem to work now ...

Receive messages that app 'x' has been granted Superuser Permissions- Not sure if this only occurs if rooted?

Able to install and use Samba Filesharing app, accessing the phone from my laptop to delete, copy, move files on the phone

Adfree works, able to upgrade definitions etc.

Titanium Backup works, ALL requirements have a tick except Dropbox, which I have not defined/activated

'System Tuner' allows me to remove 'system apps' like LG Smartworld.

Prior to using Unlockroot, none of these worked as advertised.

Also as indicated by someone else .. Boot time seems to take a little longer.

So in terms of usage, no complaints, my apps function as before, i.e. 'seems' to be' rooted but I am not capable of being able to technically state it is REALLY rooted.

Thanks to the others for sharing, otherwise I would not have tried it, from the results of attempts by others it seems it is simply a question of 'luck'.
[LG Optimus Black] nicosdroid:
Hi all,

To root my LG-P970-V20n, I've read all this thread but nothing works for me.

When I try with UnlockRoot, I've an error: "Failed to get shell root!", FAQ from this software says: The information shows that your phone has failed to root. There is nothing we can do about it.

When I start Superoneclick 2.3.3 and after I launch UnlockRoot I've another error:

"Failed to chmod: rootutility".

Anyone has the same trouble? Or any idea to help, ton find a solution to root this phone.

Thanks,
[LG Optimus Black] mauka:
There are some cases obtaining a root Unlock Root, all of them updated to 2.2.2 to 2.3.4 via kdz. At the same time to have 2.2.2 Root, will not normally be dumped data (wipe), then through the Unlock Root, Root received. That's what I'm trying to flash through SmartFlashTool_External to 2.2.2, stuck updated through kdz.

But kdz now does not work, there is a solution http://xdaforums.com/showthread.php?t=1476189, until it turns out.

Translating through google translator.
[LG Optimus Black] adxgrave:
Yep. Maybe updating to gb via kdz have a better chance to obtain root, maybe that's why they tried it hard to block the tool. Lg, just let us do whatever we want with our phone!
[LG Optimus Black] Maneth:
Hi ! Have anyone try to update the official firmware (no flash) with OTA RootKeaper Voodoo ?
[LG Optimus Black] Poeta:
Me and don't work.
[LG Optimus Black] N00BY0815:
OMG! Never use OTA Updates! this probably screwed up as many phones, as all normal flashing attempts together ;) just as an advice :D
[LG Optimus Black] gabwerkz:
Just a concern:

http://xdaforums.com/showpost.php?p=22094518&postcount=463

I've had a brief test with the Stock German V20N KDZ before, and I pulled the system files via adb. At the time when we we're trying to find to root it, or make a flashable zip. Today I remembered the files. I wanted to see if bluetooth problem was in it. So what I did was.

Make Zeus v2.1 zip as base

Replace all system files in the zip with the ones I pulled before

Retain etc folder cause it was missing in the pulled files

retain boot.img of Zeus

Drag and drop superuser, su, busybox from Zeus

Booted fine, greeted me in German. I set it up.

I went to hidden menu and to my surprise: See Factory Version

Now I had a concern before Zeus came out. The rooted ones, connecting the phone via LGMobile Update shows V10E. And today, just today... i see why.

You may try it and tell me if we have the same Factory Version.

So what am I missing here?
[LG Optimus Black] George Jetson:
Mine shows 10a:confused: I install 10a rom with smart flash tool than I make root and install cmw.Than I install zeus v2.1.
[LG Optimus Black] N00BY0815:
I guess it is some kind of bug, since when u plug it to usb and check for an update via b2c at least I get the message, that none is availiable :-)

Edit:

And before i updated to v20n, i had v10c installed...not v10e
[LG Optimus Black] gabwerkz:
Does that mean it records froyo, is that what you're trying to imply? I'm using CM before I tried repacks. I installed V20N kdz now via O3D method.

LG Mobile Support Tool detect V20N.
[LG Optimus Black] N00BY0815:
Has already been answered in another thread, but it seems to be the last version of official kdz u gad flashed to your device. Back to root attempts ;)
[LG Optimus Black] mihaiolimpiu:
As I gathered information from across the web, all users who rooted their phones were previously on some version of Froyo (Android 2.2.2), then updated to 20N German (Most of them), and obtained root trough UNLOCK ROOT program...

Are there any reports that other programs worked?

What I'm curious is that I fallowed the exact same procedure, but no matter how many times I tried, I couldn't obtain root...

I know there are Rooted ROMS floating around the web, but they came too late for me, and obtaining a backup for my apps is a priority for me. What do you know for a backup I need root so I'm stuck!

As some people discussed here, there are traces from old roms, maybe leftover files that somehow allowed the rooting process to take place... (SEE roms showing v10e AFTER flashing with 2.3 ROMS).
[LG Optimus Black] George Jetson:
My friend (member in turkish forum) he did root 20n europe and 20n germany with unlock root.Of coursehe did one time and I dont know he took nandroid backups or not.But he said :

he has windows7 64 bit

he tried e-sata usb port

disabled lg modem device

and he try dozens of times.
[LG Optimus Black] Kshysiek:
As a curiosity I will tell You that I tried root one more time after unrooting my phone and it didn't work like first first time!! I don't know why. I had to unroot my phone back because I send it to LG for repair (I have problem with glass). Then out of curiosity I checked if I can do root again and I can't. I did everything same like first time. So it seems that case before was accident. Fortunately I have Nandroid backup of my rooted rom:)
[LG Optimus Black] nirats:
This works !!! YAyyyy just tried it with Unlock Root and the steps you had mentioned and it just worked. i have 2.3.4 V20N German Rom. Thanks George Jetson
[LG Optimus Black] mihaiolimpiu:
Yes! It works... Confirmed, unlock root works if you disable lg modem device!
[LG Optimus Black] -Sat-:
I'v tried with unlock root, but it doesn't works... I have an OB flashed with KDZ from v10a to v20n Italy...
[LG Optimus Black] mihaiolimpiu:
Stable ROOT METHOD found!

Disabling LG MODEM DEVICE under modems makes UNLOCKROOT work on every firmware! TESTED on 20N german version!

Here is the proof :)

Here are the drivers I used:

[LG Optimus Black] mihaiolimpiu:
I already shared phone screens... what proof do you want more?
[LG Optimus Black] cdrugo:
ahahahaah

unlock-root is a virus and doesnt work... only in Romania works :D
[LG Optimus Black] kostas_thess:
v20N Greek is not working :(
[LG Optimus Black] mihaiolimpiu:
If you want to share or post your result, please do so, if you want to mock other people, then... I'll let the moderators take care of you!

Unlockroot is sometimes detected as a false positive because of the exploits it uses... look at the description it gives you, and you will see... It has already been discussed millions times before!

The method works... I tried every method until now, NONE worked... This one worked the first time I tried, so ... Maybe we are a little smarter then?!

I used 20N German, the phone was rooted before on 10E European...updated trough kdz, didn't do wipe phone/user data, OS i used Win7 32, Unlock root latest version,...

Before this I tried superoneclick all versions, unlock root, the virgin USB port method, windows xp with all methods, nothing worked, only thing that I did, I think I used the secret phone menu and clicked USB mode AP?!?!?! I'm not shure but that didn't changed anything!
[LG Optimus Black] kostas_thess:
as i see push the busybox and su but after that is not working :( cant get shell access
[LG Optimus Black] T-1311:
I gain root too.

German V20N, updraded via LG-Tool from V10E (Original with root)

Enabled USB-Debugging, Plug into a new USB-Port, started UnlockRoot 2.2.2 and finished without errors.
[LG Optimus Black] mihaiolimpiu:
Finallly positive feedback! Did you disabled LGE MODEM? or you didn't had to?
[LG Optimus Black] Redpik:
So, i installed win7 x32 to a virtual machine :) the big problem is that unlockroot doesn't start. Anyone knows about this?
[LG Optimus Black] kostas_thess:
As i see and at another forums the confirm that ONLY german v20N takes root .

All other versions dont take it ...

:( They has changed something on kernel as i can imagine and dont take tha exploits
[LG Optimus Black] T-1311:
I did Not disable the Modem.

[LG Optimus Black] Redpik:
Question for those who rooted : what version of windows are you using?
[LG Optimus Black] T-1311:
Mine is Win 7 HP 32bit (ASUS Eee PC 1001HA)
[LG Optimus Black] N00BY0815:
Windows xp 32 bit. Did anyone have win enabler on?
[LG Optimus Black] mihaiolimpiu:
As I stated before win7 32, no windows enabler, I just disabled LGE modem under Modems in Hardware settings!

As a conclusion to all things posted it seems UNLOCKROOT does indeed work, but in a very few select cases, and only when something out of the usual happens!

I tried countless times to root my phone, but no go, until George Jetson posted his message and I decided to give one final try. Nothing changed from my usual setup, I don't think the drivers have something to do, just the way the exploit works!

What's interesting, during the rooting process the phone didn't reboot! I know that every time when using SuperOneClick the phone reboots!
[LG Optimus Black] Redpik:
Superoneclick reboots to enable adb parser mode :) So everybody rooted on Windows on 32 bits. I couldn't run Unlockroot on my virtual machine yesterday giving me an Chinese Message and close itself. 32 bits windows can root. Yeey!

Anybody knows what says this error?
[LG Optimus Black] nirats:

[LG Optimus Black] N00BY0815:
NOONE CAN UNDERSTAND THIS!

Either write in proper english, and if you dont speak it properly, use google translator, should provide understandable translations as well...
[LG Optimus Black] Redpik:
I tried on two computers with Win7 x64 and didn't work at all. Tried different drivers. Flashed Patched 20b and I'm happy. I still think there's something fishy. But who knows. We;ll find out eventually.
[LG Optimus Black] N00BY0815:
I just reflashed V20n some hours ago, and tried some methods posted here, couldnt get it rooted neither... Maybe it really has got something to do with a prerooted v10x, or just luck :D anyway, lets wait until they release the bin files and we all will get our patch/root ;) Till then, flash back to v10x with smartflash, root it, install any zip you like, feel free to take my nandroid from first post, redys or other repacks/modifications, Huexxx zeus Rom, which is great, or CM if you wanna get a taste of the magic/bugs :D

To backup your stuff, search for app backup on market, LG PC Suite, and syncing should do it for you ;)

Finally i have rooted my LG P970 (V20N Portugal)

SO: Windows 7 HP (32 bit)

Tools: Unlockroot 2.2.2 and Windows Enabler

Steps:

- Open Windows Enabler

- Plug in USB cable

- Exit Windows enabler or disable the LG Virtual Modem and LG Android Platform USB Modem

- Disable the LG Virtual Modem and LG Android Platform USB Modem or exit Windows Enabler

- Open Unlockroot and Root

- Unlockroot show a message to Reboot

- Reboot

- Phone rooted :D

Finally after so many tries and exploits used...

After rooted i do a factory reset to try again but the phone is rooted after the factory reset.
[LG Optimus Black] N00BY0815:
So what? either enable this or disable the other...

Pls explain again, since this is not a method, that I could follow...

maybe I am just tired, or stupid :D

Oh and only open Windows Enabler, or also turn it on?

Pls be more precise ;)
