Well, I've been at the Big-N00b topic. This is what I read:
The UNROOT
If you wanna unroot your device, why so ever, the easiest way is to use Unlock Root (Link above) open it, connect your phone via USB, enable Debugging Mode and click unroot. If you wanna unroot it, e.g. to be able to send it back to LG on warranty, better use the method below, to unbrick your device with R&D tool.
Because like this, you will get back an unrooted device, which has also been hardresetted. So LG will hardly/never get a clue, that it has ever been rooted.
Dont forget to format your SD card as well

I've tried the Unlock Root but the only thing I got was: failed to get shell root.
Anyone have an idea how to unroot it now?
Thanks.
Use the post below, as stated in my thread. It says UNBRICKING.
Flash a new software (the older the better) e.g. v10a to your phone, reboot it 2 times, then update it to the version availiable for you via B2C
Read it all dude

I've read it all, but I wanted to unroot it without having to do that much. What do you mean by B2C? LG PC Suite? Anyway, thanks for helping.
Seems like you didnt read carefully...
B2C is one of the first lines in that guide... You should really start reading carefully.
It is the Lg Update Tool.
Flashing with smartflash takes pretty exactly 5 Minutes, updating with B2C about 10-15 minutes and your all done. If you dont wanna, you dont need to, but you were asking for a solution. So take it or leave it.

So, I got one more question. Right now I'm on stock 2.3.3. If LG releases ICS and I upgrade it with LG PC Suite will I be unrooted aswell?
Of course it will... That's what was the problem with rooting Gingerbread in the beginning was. Cause as soon as you updated a rooted version of froyo, it was rooted no longer...
So will it be with ICS as well

You can "downgrade" your system to Stock ROM Froyo, then you can connect it to LG Update. Is that what you want? CMIIW.
Do u have a nandriod backup?since updating from stock rom should be no problem...
reboot into recovery, wipe data/factory reset, wipe dalvik cahce, wipe cahce partition
turn off the phone, take out the battery..download R&D test tool, windows enabler and the kdz u want to flash. start R&D test tool , press and hold the vol up button plug the usb to the phone it show that u are software update mode..select the kdz click ces web upgrade test then upgrade start...
thats the way i went back from cm7 to stock v10g
http://forum.xda-developers.com/showthread.php?t=1275315
its not so risky...it was about 10-15min
On cm7 the b2c tool want recognize your phone, and the kdz will not too! JUST if you turn off your phone!
Thank u so much donjamal! That's the help I'm looking for! BTW can I just update to stock online and skip the KDZ part?

u can not do it online, cuz if u use the b2c tool it looks like it recognize your phone but if u press upgrade, there will be an error message something like this: connection error between the pc and the phone... thats the reason why u sohuld turn off your phone and use R&D test tool
and of course all the drivers needs to be installed on your pc
What I mean is immediate online update without R&D and KDZ like:
1. Boot to Recovery then wipe data, dalvik and cache partitions
2. Factory Reset
3. Online lg Official update
Is that safe?

U should use r&d (doesnt require hard reset...but i did to be on the safe side or kdz updater (which requires hard reset) as i mentioned above.

Eh so I'm quite new The Optimus Black (I just got it on last Saturday!!)
I really like the phone! And I was trying to update to Gingerbread but it tells me that it's already up to date (though it's obviously on Froyo 2.2.2)
So I started to search on the internet how to flash GB manually but in vain...
It's not working...
I tried with both R&D test tool and KDZ Updater...
I followed this Guide: http://www.lg-phones.org/how-to-update-lg-optimus-black-to-android-2-3-4-gingerbread.html
But it's not working...
I doesn't show me the window to select Language & Country but this one (see attachment):

Thanks!!

Do the procedure again from the very begining. Power off.. press volume + ...and so on.
Just reflash it, with the same tool, redownload the files, since they might be corrupted. And check if you chose them in the right order otherwise the bootloop is guaranteed
Hello, i (think) i want to root my Lg Optimus Black,
but before making all kinds of decisions i have a few questions;
Will rooting my phone remove the warranty? because i can not afford it to drop my phone, and have to pay the full 200 euro's for it..
if it does remove my warranty, can i switch back, and remove everything so LG will still repair my phone?
I once upgraded my 2.2 froyo to 2.3 gingerbread with the LG site,
is it posible to upgrade my phone to the 'normal' android version? because i hate
the LG Interface.. and if i can, will this also remove my warranty?
If i am going to root, i will be using several forum posts found on XDA.
if i follow these steps: http://forum.xda-developers.com/showpost.php?p=23790405&postcount=171
and then these: http://forum.xda-developers.com/showthread.php?t=1473592
will i have a stable LG optimus black, with another interface.
If rooting, or installing the default Android 2.3 is not safe to use, is there any way to Remove the horrible LG interface (The lockscreen, dialscreen, statusbar, Music app, etc. ?
if you modify the software you will loose your waranty. And you can ALWAYS go back to stock in one way or another.

1.- You can always unroot to SmartFlash and get back your warranty..
2.- if you have much problems with rooting, back to 2.2 and root, then install the Roms that you prefer!!, is more easy than injecting Recovery!!

Hello, i want to root my Optimus black.
in the system specs, it says V20o.
So i went to click on the V20o link, there i got a few steps.
at the first step you need to download a file, not only it says v20b in there, it is also from a v20B thread. so is this the right file? and the download link doesnt work...
For 20o follow this link:
http://forum.xda-developers.com/showpost.php?p=23788913&postcount=170
Download of 20o root is possible if you remove the html in the browser.
I did al the steps, but exedently clicked Clockwork mod away, so now i havent done steps 14,15 and 16! Can someone please tell me what to do! how can i get my recoberyscreen back?
Simply start with step 5 again and follow the instruction!
Done that a few times myself.

Hello! I need some help, I've been searching for a couple days about how to root my lg optimus black p970 V20a. I found your noob threat and I see the link for V20a but when I click there it sends me to a link with Root (Superuser) on firmware V20B (CIS). Does this means V20b can be use for V20a's? or is it a typo and if it easy can you please where to find the V20a.
Much appreciate!! Thanks!!
You can root it on your own (check the 3rd post of my noob how to) or ask someone, to provide it to you... I dont have time, but the how to should be self explaining You only need the LgExtract tool (posted at the end of the thread) Smartflash + Windows enabler and Superuser.zip And your pretty much done Or keep on searching for Root v20a Optimus Black

Hi everyone!
First of all, sorry if this as been asked, tonight my Google skills didn't help me find an answer.
A friend of mine owns a LG Optimus 2X (P990) bought from Fido in Canada. Currently she's on Gingerbread and would like to update to ICS (which is the latest stock rom available from what I read)
She wouldn't get the software update OTA so she tried downloading the LG Updater software from LG directly. The software detects the phone and says an update is available.
At some point, a popup appear suggesting to make a backup. So far, everything is fine. Once the backup is done and she click the "Start upgrade" button, she gets this error message : "An Unsupported operation has been attempted"
Anyone ever seen this before? Is there a way to upgrade her phone without using the LG software?
Since it's not my own phone, I would prefer not rooting it.
If rooting is really the only solution? What would be a good guide to read to do the update? (I did read a few sticky posts... 1 is the all in one tool kit... it explains each feature, but is not really a guide and I still have some questions unanswered after reading it. The other guide I read, the download links are broken)
Thank you

Alright, that didn't help at all.
First of all, I wanted to flash a stock ROM... the guide tells us to install CWM and we got stuck at the part where we have to flash the ROM because it would seem CWM won't take the KDZ (or bin/fls) files.
Now we can go to the SW Upgrade mode without the battery, but the smartflash utility time out after 3 minutes and end on an error.
We can also go to CWM with the battery... but with no apparent way to flash a stock rom.
We're stuck at the moment.
Edit : So in the end we flashed only the BIN file instead of both BIN and FLS. No more errors and the phone rebooted correctly under ICS! Yay!

Hi, I rooted my phone following [GUIDE][ROOT] How to Root your LG Optimus 4X HD (O4X P880) a while back ago. Now I`d like to try JB, but after reading up I`m more confused than enlightened...(there are soo many flashers,upgraders,versions etc)
I`m on baseband L6260_MODEM_SIC_02.1216.01 with Kernel 2.6.39.4.I`ve tried to upgrade the CWM to 6.0.3.1 and 6.0.4.4 in recovery and they
went smooth, however when I reboot recovery I`m still on 6.0.1.1. I use LGUnited_50MAN3 Ver_3.10.1 on Win7 64 bit.
Would someone be so kind to guide a confused man?

Plenty of ways, search and you shall find...
you need to unlock bootloader before flashing cwm.
now you have to flash stock kdz file and start over again.
