[Q] LGMobile update service PROBLEM! Help Please?

Hi all!
Few days ago i updated my lg p990 via LGMobile update service to 2.3.4 Gingerbread V20m with no problems. I`m from Serbia btw. Then i rooted my phone and installed clockwork recovery to backup my rom. I made a mistake to do that after i performed root so now when i restore my rom the phone is rooted again and i can`t use update utility anymore! It says my model is not suported. I then used SuperOneClick to unroot and r1-stockrecovery-2x-unsigned zip to remove recovery and it did that but still can`t update or restore original stock V20m rom with update utility. I even managed to install V20l ROM and baseband via Smartflash and offcourse still no update posibility and "not supported model" message. Yesterday i downloaded from XDA, Netherland stock V20m but, guess what, still not supported. Can anyone tell me how to or what to do to make my phone update officialy again with LG tool. THNX in advance

Well you have go download correct files. I don't remember very well where the download location is.
But I have managed to do full installation of original lg software over the cyanogenmod.
There is a step by step guide on this forum how to do this.
I am from Croatia and after that my phone accept automaticly update.
Now I am on Cyanogenmod because it is so much better than stock.

I downloaded stock V20m rom from http://forum.xda-developers.com/showthread.php?t=1035041 and still not supported with update. Can u please find what u did and post here!? I don`t know what i didn`t try and nothing worked so far. And i have GPS isue so i have to restart phone with gps ON and then it works. I didn`t have that problem when i updated to V20m first time. I have read that it`s a problem on V20l but not on V20m. U said u use custom rom!? Is everything working properly!? No workarounds to make something work like this GPS problem!?

[Q] Different versions of the same firmware

How can I change the versions of firmware I have?
Right now i have the romanian version of the GB update and I want to install the europe open version do I have to do anything different from the regular procedure?
Thanks in advance.

you must download and install the European firmware with installer KDZ

Look into my noob how to and follow the second guide with the R&D tool procedure. Plus of course you need the v20n europe open firmware. Google for it. This way you will get europe open, although I dont see the advantages of it...

After using it for a week I found out that my screen on time went down to 3h from 4h-5h and I would like to switch back to v20n.
Thank you very much.
Related to your guide i have another question though
To unroot in a way that is harder for lg to detect it all that I have to do is update using the R&D tool?

Yes, and delete files from SD card. Of course, use the Software, that you can also get from B2C. But I guess you can also simply make an emergency recovery with B2C and then perform another factory reset from within the phone, just to be on the safe side

[Q] How to flash back to stock rom and unroot my P970?

Dear All brother
I just want to flash back to stock rom and unroot my P970 like initial status. Is there any tools or method to do so?

It's very simple, just follow the Tutorial: LG P970 (P970H) unbrick/flash using SmartFlash Tool and install whatever version of firmware you had initially, you can find V10 firmwares on the Firmwares LG P970, P970H thread.
If you want to get to the official V20 firmware, just upgrade your phone using the LG program (the one that came on the CD with your phone).
This way you'll have an "official ROM" on your phone and it won't be rooted either (it's just like it came "from factory").
Btw, you'll loose the root and the recovery functionality, but i think that's what you wanted in the first place
EDIT : replaced Samsung with LG, i was reading up on modifying my Samsung Spica and somehow mixed up the postings

[Q] Invalid software package when trying to update my phone

Hi guys!
I noticed today that there were a system update for my optimus 2x.
But after it downloaded it said validating software package and returned an error stating that the package was invalid..
Has anyone else bumped into this problem? Is it because my phone is rooted?
It is otherwise stock.
Thank you so much for your help!

Okay.
So can i ask how do i unroot the phone using CWM?
I looked at this thread: http://forum.xda-developers.com/showthread.php?t=1021554&page=2
it talks about installing a recovery.zip using CWM, but will it unroot the phone or not?
Thanks!

The name says it all and it is sticky in dev section...

Hi and thanks for the answer!
you see, my phone is already rooted. I need to unroot it in order to get the latest update from LG installed on my phone.
The reason for this is that when i download the update OTA and try to install it, i get an error message stating that i have a invalid software package.
And the reason for this as i understand, is that the phone is rooted.
i have read the roll up thread you linked to, but it does not state anywhere how to unroot the phone. And thats what i need help to do

Use smartflash and put some older version on it, then update it to current version. It will be unrooted.

Thank you for the answer, will try that!
But im struggling a bit to find the older versions though. The links to them are either down or broken. I need the EUR version.

You can flash stock v20q via cwm. If you said that your phone is rooted, install cwm and then flash this stock v20q.
If you want to downgrade, then update using lg update tool, you need smartflash and some older firmware like Euro v10d.
You need to read and search, really, all is here on the site.
At least press the thanks button if my posts are helping you, it is right here.

Thank you for the reply.
I will flash with the v20q one you mentioned. Its the version im trying to upgrade to anyway, så this seems better instead of downgrading it to stock, then upgrading using OTA!

I have 2.2 Froyo... Need help

Hello, I'd like to update my phone using Smartflash.
I have an official V20B rom which is rooted. I would like to install a new official rom but i'm completely lost when it comes to choosing the right version !
Where can I get the official V20S stock rom (which can be installed with smartflash)
Also, is there any official ICS rom ? (same, for smartflash), if so, is it fully stable ? Where can I get it ? (LG Mobile update says my phone is up to date... Huh)(I have read that you need to change the boot partition or something like that with ICS roms, is it valid for official ICS roms from LG too ?).
Do I have to unroot my phone before installing a new rom with Smartflash ?
Thanks.

1. Make sure that you have P990.
2. V20B should be a gingerbread.
3. If you read one post below yours, you could’ve find exactly what you ask official ICS for smartflash.
Cheers.

I actually have V10B sorry !
I will update via LG Tools with the kdz instead of smartflash. Is there anything to do specifically to keep my data in the phone or is it saved automatically in the LG Tools update process ?
Thanks

I think updating via LG Tool doesn't erase data on your phone... however I would strongly advise you to synchronize your contacts with gmail and backing up you apps with titanium backup in an external sd card.

Update via LG Tool didn't erase my data when I went from 2.2 to 2.3

Yes, flashing kdz do not wipe anything.
