1) try to use the LG Software update tool...that is one option
2) if not, try using the AIOT
3) just flash the KDZ file through AIOT
but just a small word of caution, back up personal data using the LG tool...if not, you will lose all your data
hope this helps you

It depends on the type of update, some are full updates which will wipe your phone (including removing root), some are incremental which will just replace some system files.
You can find out which though by going through the update process. If the uprade will wipe your phone you will get a warning stating so.
As for you wanting to go back to stock, you can simply download a stock rom from here on XDA, flash with smartflash, and you will be back to completely stock.

Unable to update Galaxy Note N7000

Hello,
I'm currently living in Chile and apparently Chile released the version 4.0.4. I tried updating my android version through kies and the phone updater and no luck :/ My phone is rooted and the kernel is [email protected]#2. I'm not sure if the inability to update is due to the fact I used a kernel from another country other than Chile (I think I used an Indian Kernel). Is there a way I can go back to the my original kernel and unroot to update normally? I also have the urge to unroot my phone since my music player has been crashing too often and feel that the problem originates from the rooting.
Note: I am a very new user and I don't know most, if not all, terms such as flashing.
Help is very much appreciated,
-Kathy
Why don't you directly update it from here ---> http://forum.xda-developers.com/showthread.php?t=1424997
Download the rom and flash it via mobile odin pro or pc odin As simple as that
Thank You! But...
Is there a way I can unroot my phone? Like going back to how I got my phone? Why isn't my phone able to update normally?

When you flash a rom using pc odin,u will be unrooted
Download the rom from above given thread and flash it using pc odin,you will be automatically unrooted
U cant possibly update due to a different version of kernel

When I flash my phone do I need a Pit file? Will this wipe all my music, apps, contacts, etc...? If I use a original chilean rom then my phone will be unrooted right?
Sorry for asking so many questions >.<

You don't need PIT files. Just Select rom file under PDA tab. No need to change any option. Just Start Flash.
And it will not erase your data on sdcard (internal or external)
Cheers
You need to backup your contacts,msgs and apps
Hope I am not to late, would be best to make efs backup before proceding, so you can always return to chili working rom. Its a backup of e.g. imei which is not easy to recover if accidentally lost.
How see toolbox thread dr ketan in general section. You need root for that. Save in multiple locations

Best Rom to solve My problems

Hi,
I have since Fev. 2012, a optimus black, but since the beginning I have problems with him.
Before, I was unable to take pictures, because every pictures I took was corrupted.
Since I upgrade to V30b, this problem was solved, but now, sometimes the message: The SD card was removed apears, and I need to reboot the phone. I installed Beyondpod to ear pod casts and all the downloaded pod casts file, after 1 day were corrupted (files with names like:┬▬¶, before the photos were the same names).
This week the phone blinked non stop, I needed remove the batery, and all settings were reserted.
Now I think my battery drains so fast, I had reserted all settings to factory defaults and now the phone is working, bus Podcasts no.
I´m sick of this phone. I wants some custom rom to see if the phone improve.
Can anyone please can help me?
Please give me the information about witch Custom ROM is better. (fast, clean, battery, in all aspects)
Tanks a lot for the help.
Sorry my bad English

is it rooted ? if yes, then you have lots of option in developer sction, the most stable rom i used recently are Marvel v11 and IZS both ICS based roms. both are great with battery and run pretty smooth.
you can try one of the Marve based stock V30F . i didn't try it yet.

If it's a rooted v20 (GB) just install ROM Manager from play store and maybe first try a Marvel12b, 11 or even 10 ... where you get a touch 5 CWM recovery with it. Than you probably have the best base you can get to install any ROM.zip from.

Guys, thanks a lot for the great help.
I´ll install the ROM and test. (my is a rooted 30b, is possible instal only the CMW and install ROM?)
After de installation done, I´ll post my experience.

I heard there is one way to install a CWM on v30, but normaly you only brick your phone when you try to get a CWM on v30. Look for unlock U boot.
http://forum.xda-developers.com/showthread.php?t=2160394
yeah, this is a way, but cwm 6 have bug sdcard unmounted, use recovery.img 5.xx.xx on this case.
IMHO, if you have SFT, it's safe to flash with Preinstallation for IZS ROM (SmartFlash): includes Smartflash and latest LG USB drivers =>
http://huexxxtuff.blogspot.com.es/2013/01/izs-rom-links.html
you should have, ics rooted and cwm on one shot. after you can make nandroid backup and test all custom rom you want.
original thread => http://forum.xda-developers.com/showthread.php?t=2115800
Case C: you already are on a new ICS rom without CWM
Quote:
- If you want, use OnlineNandroid to do a nandroid backup of your phone, I'm not responsible of your data losing
- Use Smartflash to completely flash (.bin and .fls) a V20 ROM patched with CWM with V30 baseband (you can
use my PRE_IZS_IMAGE available on my blog)

Once again let me thanks the help you gave me.
Now I am confused.
There is any tutorial to help me install the rom?
I am a newbie in this matters. I had a Galaxy tab 7 (p1000), and in that time I did install some roms, but time pass, and now I´m super confused.
I read several thing but, you gave me different solutions and I don´t now how to do.
I think the best rom (following your´s advise), is the MARVEL.
I found this: http://forum.xda-developers.com/showthread.php?t=1554274
And I choose the last: Marvel v G based on Ice Cream Sandwich 4.0.4 v 30d France - deodexed and zipalligned
Following the instructions of the link, I only need do this:
1. You will need a rooted Optimus Black and boot in CWM Recovery or use ROM Manager.
2. Copy the zip file in SDCard.
3. Install zip file.
This is correct?
I need to root the boot? How can I confirm is I have a rooted boot?
SaschaKH gave me this link: http://forum.xda-developers.com/showthread.php?t=2160394
Can I use this instructions to root the boot?
For all operations I need the CWM.Can i install in play store? I found the ClockworkMod (ROM MANAGER) free version. Can I use this version?
Exist also the Rom Manager Premium, for what I need, the free version is OK or I need the pay version?
To finish: What is:
1- SFT?
2 - deodexed and zipalligned?
Thank a lot for all the help.
Sorry for this questions, I want to learn more about this world, and I´m starting. I count with you guys.
Thanks a lot.
Once again sorry for all my questions and my bad English. (I´m Learning English too)

You didn't read it well. It says to root your phone and to boot to CWM. The thing with U-boot is to get rid of the locked bootloader wich gives you an LG Security Error if you install any alternative recovery.
You can follow the instructions given but I didn't try it myself.
What I found easier is to do as NOOBY wrote in his tutorial : flash a V20 patched rom (Gingerbread stock rom rooted and with CWM), like that you'll only have to do the wipes required in CWM and then flash Marvel Rom - which of course you put on your sdcard -.
SFT (= SmartFlashTool, for flashing a firmware easily)
Btw to use that tool you need of course our phone's drivers installed.

I said I'd brick my phone and it seams i was right.
I install CMW and I choose "backup nandroid", the phone turned off and now appears the LG logo and the information Security Error.
How can I fix it?

I had selected the option "backup current rom"
And after, the program installed something, asked me permission to reboot, and appears the problem.
I install again with SFT a V30b rom.
I need to start again, but now I don't know what I did wrong.
Hum... If you installed CWM directly from a stock ICS rom, that's normal that you had that error. ^^

Yes it is what I did.
Is any other way to install CMW?
Even in the tutorial said: "Then you need to install CWM (Clock Work Mod), you can do this e.g. by downloading ROM Manager, install it, open it
and find Install Clockwork Mod Recovery. Hit it, wait some seconds and click LGE optimus Black. Wait again, till the file has been downloaded and installed and your all set Now you can reboot into Recovery, with the second option. It says, what it does: Reboot to recovery"
But I tried also reboot using the option "Reboot to recovery" and the phone reboot and reset with factory defaults.
How can I use other way?
Thanks
In the tutorial it says that for Gingerbread rom.
I don't remember if it is in Ilko or NOOBY's thread but you should use SFT to flash a patched Gingerbread rom. Since it is rooted and with CMW, it may be easier to you for flashing another rom from that.

Back on track.
I made it. I installed the Marvel G, but my problem still maintains (I use BeyondPod) and in the podcast folder appears a lot of corrupt files), I don´t see any change from stock ROM, but I think this is the objective of this ROM.
But now I am ready and prepared to install all ROMS I Want using the CMW, and install from zip file.
I will continue testing some ROMS.
Witch ROM do you recomend? I don´t need fancy style or other complicated thing, I just need what a stable, low consumption batery, and fast thing.
Once again thanks a lot for the help

Stock ROM through CWM

Hi everyone. I have a LG Optimus Black and I need to take it to service. Because I root-ed and installed custom rom I need to go back to stock version. I have a little problem because my computer doesn't recognize the phone anymore so I can't use smartflash. Does anyone of you know another way to return to stock version? Can I flash stock trough CWM? I need v10b. Your help would be greatly appreciated. Have a nice evening and thank you for your answers!
try to change usb port, not usb 3.0 but on usb 2.0 in SW mode for able to use SFT
I already tried that. I even tried a different computer. Does no one have a stock version that I could flash trough CWM? Even if it is ICS ore something like that. Thanks a lot anyway!
with lg Tools maybe, LGMobile Update (B2C), support, recovery phone.

you do realize that flashing even a stock rom through cwm will still not make the phone "stock". you'd still have cwm installed and need to get rid of that. try flashing a kdz instead...

His post stated he has a problem with his USB. Flashing kdz or files in SmartFlash is not an option.
The link posted above is not a regular "stock" ROM. It's a project that contains stock "recovery.img" inside the zip. Like what was discussed here http://forum.xda-developers.com/showthread.php?t=2224465
It is the same adding the unlocked bootloader together with the recovery http://forum.xda-developers.com/showthread.php?t=2160394 on a flashable zip or any .img on a certain partition.
Code:
package_extract_file("x-loader.img", "/dev/block/mmcblk0p1");
package_extract_file("u-boot.img", "/dev/block/mmcblk0p2");
package_extract_file("boot.img", "/dev/block/mmcblk0p3");
package_extract_file("recovery.img", "/dev/block/mmcblk0p4");

I need a dev on this case or any pro or someone with experience.....

Update it how?
You want it back to Stock ICS? I think you have to use smart flashtool and update using the factory image.
Any other updates/upgrades can be done via CWM/TWRP.
Hmm second thought....

I generally try and steer folks away from anything greater than Gingerbread for the P970. ICS + JB aren't anywhere as stable or reliable. My ROM picks are:
Marvel 9 (with the "There is no delay patch")
Zeus 6.4
I ran an ICS ROM for quite a while and loved it, but I grew tired of the random hiccups, lockups, and freezes. GB is solid on the 970. If you're adventurous, you can try JB or Kitkat. For JB, I'd maybe look at Mackay ROM. For KitKat, Nameless ROM would be my choice. These two ROMs appear to be the only ones that actually have any activity.
Again, for a daily driver, I'd look hard at GB-based ROMs. All of the ROMs should have install instructions on first page of their respective forums.
