This says unbricking? sorry i am noob..
but asume this is some sort of unroot, i can do al the steps in the treadh
with my custom ROM and it will come out like a LG phone, i can send to LG
to repear it?

That method will completely reset your phone. It means it will unroot your phone. Just follow the step and then after that you can send it into service centre. You can also use that method if you experience bootloop or if you brick your OB.

The LG smartflash tool will return your phone to the state that it came from the factory. It erases all memory, boot, recovery (where root is) sectors and the rom that was currently installed.
Then it installs the official LG boot, recovery and system sectors, leaving little trace of any software modifications.
If you have the original SD card in ur phone, I would either take it out or format it, before sending it for repair, just to make sure they have no excuse to void your warranty.

Hi, nvflash means back to stock. Nvflash should bring you to stock with no root, recovery, nothing at all... I guess, in order to remove Cwm, is to use nvflash.
Here's a thread of mine on how to flash back to stock
http://forum.xda-developers.com/showthread.php?t=1127849
Mh, thank you all for the answers, but my big problem is that I need the 1&1 branding in the rom. And I really don´t know how to get it (on a stock rom).

What does the 1&1 branding look like? Only knew unbranded and Vodafone-branded firmware, thought that 1&1 distributes the unbranded 2X
Paul gave a zip in modaco forum to remove CWM (cant post the link here, but just search remove cwm optimus 2x and its there in the second result)
how can you generate such a zip? as I want to backup my stock recovery from brazil claro operator V10a
or can I flash taht zip in my V10 and all will be good?

[Q] How to unroot the v20N?

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

Are you on stock kernel? If so then flash some safe kernel and try full wipe, if that too doesn't help, then flash stock firmware using pc odin.
I am assuming you are on ICS, as you didn't provide any info. You should have mentioned the method used for root and everything.

Now i cant even get to download mode to use odin to flash GB rom. I tried flashing abyss kernel using srock ICS recovery and that's the main reason for current situation i think. Any help?

Take it to a samsung service center and ask them to reset the phone. Tell them its too slow after the latest update using kies. If there is a problem with the motherboard they will report back and replace under warranty.
Else they will install the OS completely new and you can start from scratch to root and install other custom roms.
Try using USB jig to go to download mode, try it first. Jig is not expensive.

No it's not bricked. Yes you lose your warranty, but you can unroot your Note. Don't warry Note is so good phone, that you don't need warranty

Then if it's not bricked why i need to remove the battery for 1 hour and wait an other 2 hours to finally open my phone after a simple turn off? Thats why i want the warranty so i can take the phone to samsung and fix this issue. And im afraid to unroot it cause when ever i try to put my phone on recovery mode its stucks and take for ever to open againm\

1. try going into recovery and do a factory reset.
2. if that doesn't help, reflash and all your problems are solved.
do a clockwork mod backup before messing around next time

Use LG mobile support tool, also its "stuck" not "stock"
What are you on? He needs to reflash the rom as he changed the fonts and some may be missing, happens to loads of people, no need for a factory reset, just restore the fonts folder or reflash the rom, if you don't have an unlocked bootloader, bite the bullet, unlock ya bootloader and come over to AOSP in which i would recommend a 4.2.2 ROM.. or do the long winded way of flashing the stock Rom, your all giving some real extreme methods, it doesn't have to be this complicated..

If you're installing a custom recovery then you have unlocked your bootloader which means your warranty is already void (If LG decide that you have done something to cause the problem).

Im not aware of anyone bricking this (non-DEV version) phone, LG's download mode is pretty low level, the kdz packages also contain a boot loader so you would find it difficult to irreversibly brick this phone
Thanks Lads i got it working

It would be nice of you to tell how did you do it, so that if anyone else has the same problem can solve it with a quick search instead of starting another thread
