Is it possible to upgrade phone s/w after rooting?

Today when I tried upgrading my system software ota and using LGMobile Support Tool, I got the "Invalid software package" and "Software update is not supported for this model" respectively.
I rooted my phone using SuperOneClick and uninstalled the Car Home app and F-Secure from the stock ROM. Nothing else was touched after that.
Some other versioning details on my phone:
LGE Version: LGP990-V10c
Kernel version 2.6.32.9
Baseband version: 1035.21_20110622
My question is that after rooting my phone in my case, can I still install official s/w updates from LG?
I also "unrooted" my phone using SuperOneClick but I am still getting the same s/w upgrade error above.
Otherwise, does anyone know why the error above might have occured?

Your phone is rooted so u cant update your device through lg. Flash a new rom or unroot

I forgot to mention that I tried to "Unroot" using SuperOneClick as well but I still get the same upgrading errors after that.

Do you have CWM Recovery installed?
If you do, that's the problem because the LG updater can't reboot the phone properly if it has a custom recovery installed.
You should flash a stock rom using SmartFlash tool and then use the LG updater.

Download stock ROM and use smartflash

Make sure you read through there are 2 files, the baseband and the main ROM

Thanks for the advice guys. I will give it a try.
Another question that I have is that is the baseband version and ROM version related? Can I use the most updated stock ROM version available for my region and an older baseband version?
For eg:
ROM version: BIN_LGP990AT-00-V10c-525-05-JUN-28-2011+0
Baseband version: Baseband 1035.21_20110606 instead of using Baseband 1035.21_20110614
Will there be any side effects if I do that?
*Edited: Ok. Doing a google search on this topic reveals a whole lot of understanding. Thanks guys!

Are sure about this? I have cwm installed, and updated to 10d with lg update tool after recovering a backup of stock 10c. (Was on miui before the restore)
It took a few tries, but it worked!

[Q] Revert from CM7 to stock without having a backup

My friend wants to revert his phone back to stock from CM7 after getting tired of the bugs that are still in CM7. Unfortunately, I can't find any backup of the stock ROM that he used to have on his CWM. After googling a bit I couldn't find any more information about how to revert, since everyone suggested that i simply restored from the former backup. If there is a way to revert without it, it would be awesome if anyone of you can point me in the right direction about how I should do that!

I've tried to open SmartFlash, but it didn't recognize the phone even though I used the LG drivers that was linked to in the guide.
I even tried to flash the ROM found in this thread/reply but only ending up in a boot loop. Is this because of some EXT3/EXT4 format problems...?
Anyways, have reverted back to CM7 now and are still looking for help...

You could flash the latest leaked stock V20o from here: http://forum.xda-developers.com/showthread.php?t=1408919 - using CWM.

revert from cm7 to stock
.i used smartflash but im still on caynogenmod 7.2 so there is nothing happend
what to do

If you used smartflash you can't be on cm7 anymore. There must have been an error during process and flash had abort before the end.
Just redo it, and be sure you phone was correctly detected.
And try eventually nvflash to come back to stock ROM. See dedicated threads.

I used the link provided by nundoo and it worked. Thanks for all your suggestions!
Striatum_bdr, I didn't do anything to the phone with smart flash because I couldn't start the process (the button was grayed out and I couldn't select a COM port). Thanks anyways!

Reverting to fryo 2.2??

Hw can i go back to fryo 2.2 on my p990?
Sent from my LG-P990hN using XDA

If you are rooted with cwm, flash some froyo based roms (recommendation to topogigi`s one). If not or you want all stock, use smartflash to flash froyo firmware on. Google for v10 firmware download links in smartflash format. Is there some particular reason for downgrading?

Yes i am unable to unlock my phone nothing seems to work and i have been told to try to unlock it on 2.2

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

JB <-> KK back and forth

Hi
I'm using a VZW G2 VS980, on 12B. I rooted it, install CWM with Simple tool V3.2
I installed Cloudyfa 's CloudyPro 2.2 (KK), all the steps are done correctly, it worked but a little buggy.
The stupid thing is I tried to restore the phone with CWM from the backup (of the 12B rom), and now it stucks in the boot LG logo. I can still access CWM though, works fine.
The question is: should I sideload another ROM (or recovery - KK based) and go from there to save time or go back to stock (11A)? And then how should I procceed to get a latest custom KK rom?
Thanks guys

Flash cloudyfa Rom again so u can boot up and download a jb baseband and flash that. Wipe as normal then restore your jb backup.

Hi
Thanks but I tried that, stucked at LG logo too...
So when I restored from the backup, the baseband is still KK? (I flashed KK baseband before flashing cloudy)

You need both a JB backup and be running the JB baseband. If you did not explicitly install a JB baseband and restore a JB backup you have one or the other but not both.
A trouble I had was even though I restored the JB baseband and restored a JB backup it still didn't boot and that required dirty flashing my ROM over to get it to work.

The thing is I'm trying to get a custom KK rom that works, I don't want to go back to JB.
So should I go back completely to JB (like you said, falsh JB baseband and restore) or somehow flash another KK rom?
