Hey guys,
I currently have GB operating system. I want to root my LG Optimus Black. I was wondering if I could upgrade my OS to ICS after rooting my device. LG will soon announce ICS for Optimus Black. Will I be able to upgrade my OS?
yep
Are you sure?
Hey buddy, very thnx for your answer but just confirming........ ARE YOU SURE? This is my first smartphone and I really want to upgrade to ICS.
yes i am sure with this phone, no locked bootloader etc.
you can return its original always.
Unless you have inside news from LG or know something the rest of this community doesn't, I wouldn't wait for official LG ISC (or any ics) too soon
Make sure you do a nandroid backup of your stock ROM using recovery, and everything will be good
no need this. there are bin and fls files of stock roms and they can be flashed with smart flash tool.
dont afraid friend. only root your device and relax

Hello, I dough I can do very much at this point then ask for help.
Yesterday I used LG KDZ tool to install update to my Wind Mobile LG Optimus x2 which is P999. With the help of KDZ I got the T-Mobile update to 2.3 on it and honestly I hate T-Mobile update it just sucks so much.
I did some reading around and try to flash the ROM and some how put on a backup that was also posted here on the forums of stock Wind Mobile LG Optimus ROM.
The problem is I never rooted it while it was at 2.2 and at 2.3, I can't root it with one click rooter it just does not work I gets to Step #7 and you get device rooted but its actually is not so I can't restore to the backup I download from XDA.
I honestly would like something similar to stock 2.2 that comes with WIND LG so if you can help out to either restore it to stock ROM or in some way move it from T-Mobile update back to 2.2 without the T-Mobile preloaded and other T-Mobile blobware crap that comes with it.
Hello!

Hi Guys I'm a complete noob so please no pointing and laughing!!! lol
I recently bought a second hand K990 which was rooted. It was advertised as a k999 and me rushing, flashed a stock k999 firmware to the fone without checking properly, I have looked but cant seem to figure out how to flash it back to standard k990 firmware any help would be much appreciated, but please bare in mind I'm new to this, I dont want custom roms or root just a stock standard K990
cheers guys

Wait, did you mean p990 and p999
?
yes sorry p990 and p999.
I think I have flashed the wrong rom for my model, all my serial numbers and paperwork say p990 but it wont run any p990 roms just boot loops all the time I can get it to run p999 roms but it has the unknown baseband issue? can anyone help?
I'm flashing with cwm...
The easiest way to whip it back into shape is probably to NVFlash an old rom, root it and install CWM and continue from there.
Sorry do you have P990 or p999? And is a stock P990 or stock p999 in your p990/p999? I'm confused at the moment.

Sorry forgot to post that I managed to get it back by using this exact method installed CWM and flashed an old rom to the phone, then wiped the lot including cwm I was then able to connect to nvflash, it wouldn't do this while I had the p999 rom installed, once NVflash was done installing a stock rom I managed to boot up and now have the fone working thanks for all the intended help guys ... I dare not touch it now as it's quite finnicky and I dont want to mess it up again! so looks like Froyo for me lol thanks again.
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

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
