[Q]unroot lg 2x to not lose warranty - LG Optimus 2x

Hi everybody. Before starting, i must ask you to apologize me for my bad english. I'm new on Android and I've rooted my lg 2x last week, after lg released gingerbread 2.3.4. My question is: (even if probably someone has already answered my question in another thread, n im sorry for that, but unfortunatelly if someone has i didnt find the answer) if i flash a new rom (i was thinking about cyanogen's one) and then i have to take my phone to the lg assistance for any kind of problem, how will i revert this process?? will i have to unroot and then flash a stock rom or just unroot my phone or what?? still didnt get it, sorry for that but im a real noob
thx for your time

use smartflash
Code:

it will delete all your user data and back to stock rom again. so you don't need to worry about the warranty.

[Q] Help!! K990 with K999 firmware

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
Beejay
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.

[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

Can OS be upgraded officially after rooting device?

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

[Q] Question. I don't know where to start

Firstly, Hello. I'm somehow new. The most i've done with my phone is root it and flashed cm10 nightlies and updating.
Now, im planning to switched to an ics rom.. now, im stuck. I've been reading a lot and still a bit confused.
I am planning to get this. DjangoManouche X 1.2.1
im currently at cm10.1-20130110.
BB. LGP990AT-00-V20i-ESA-XXX-May-16-2012+0
CWM: 6.0.1.5
im planning to follow the 'how to install...' from the DM1.2.1 thread..
first it says to download AIO tools. ive done that. do i just have to follow the option 4?
the thread says install 30 based CWM.. im a bit confused, do i have to flash first the BB to 30? ive read the basebad overview but didnt see if BB 30 is compatible in my country (Philippines) (or ive understood it wrong and that any BB works on any country?)
sorry, im just confused..
so...
1.download AIO tools?
2.smartflash baseband to 30a/30b? or i just need to change partition from old to new? [all using AIO tools]
4.install a new CWM 5 or 6?
3.and then flash the custom rom?
btw, is backing up and restoring nandroid backup a necessity?
i dont care about my files or anything... i just want to get on that ics bootloader with that custom rom.
sorry if i've confused you too :crying:
OH! SORRY! ive just realised. ive badly named the title (out of all my confusion).. i dont know how to rename it.. my bad...
Go this way:
1_Smartflash an official V30A Rom (for what I know the V30B is still available only as .kdz so it's not that easy)
2_Download the AIO tool and unlock bootloader, root and flash CWM. It's really easy, just follow the steps.
3_Install the ROM you prefer based on the new bootlader
wow. thanks. those are easy steps.. my brain crashed from bad understanding of basebands. haha
thanks. will try as soon as i get back from school.
lastly, the only downloads i need are the BB files, aio tool, and the custom rom?
It's very easy! You'll just have to focus a bit on these things! Anyways, we are always there to help!
