Hi guys, i was trying to upgrade my LG990 with a Custom Rom but apparently i misread that the ROM i was trying to install was for LG999 and now i've that installed, but i don't know how to remove / replace it with a standard LG990 ROM.
I've tried with Smartflash but i don't think it recognize my phone because i've P999 ROM installed...i really need your help
PS: I'm a total noob with cellphones.

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.
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.
after backreading for a couple of days, i have seen a lot ways to root & install recovery on our OptimusBlack .. . mine is V20B im knowledgeable enough about modding phones.. last two are OptimusOne(frroyo) & X8(eclair) ~
this one http://forum.xda-developers.com/showthread.php?t=1456274
or this one using BlackJack Method http://forum.xda-developers.com/showthread.php?t=1111771
now my question is which method do you think is much easier to get 100% SUCCESS on ROOT
someone here who get a successfull root access using BlackJack?
any feedbakcs?
IMHO, if you still om froyo, the first one should work best (SoC right?)
But GB? Try this http://forum.xda-developers.com/showthread.php?p=23790405

Question: Does this method of rooting your Black leave the Phone untouched?
Cause my mobo died on me - and after the repair i got it back from maintenance with Stock V20N on it. I flashed then V20C, rooted it with SOC and put my Nadroid backup on it. I had then to install the LG Update (cheat with own little Webserver and edited LMHOST) to update to V20N / V20O. Now i am on V20O......
I have finally the phone and layout i like but miss root to Backup the current ROM.So after playing hours with it - and the upcoming CMW9 or Miui ROM around the corner - i need Clockword Mod. So question again short:
How to root V20O without losing settings / data / apps?
Pls advice and sorry if i overread the solution in some of the threads - i read them nearly all....

that method is for rooting GB right? but what about installing CWM?
Got my new OB and its on GB v20b..
That method is for flashing an already rooted version of v20.
Flash it (use the same version as you already have and make no wipes after)
then install superuser.zip and you ll have access to CWM.
That s all you gotta do.
Or flash v10a or similar with smartflash, root it, install cwm and then install any custom ROM you want. That s probably even easier.

okay.. now im confused where's the real thread or link for rooting GB v20b?
v20o root does not work
hi there,
first of all, I'm a noob in rooting and flashing, etc. I have a question regarding the mentioned v20o flashing (by SergovnikRZM):
I downloaded and installed all files, but in SmartFlashTool the start button is grey, I cannot start the process.
Also I cannot choose the Com Port and the LG Mobile USB serial port as the picture shows.
What should I do? Do you have any idea?
(I have a v20o Hungarian rom and the OS is xp sp3)
Thanks in advance and sorry if it's trivial but it is not mentioned in the steps..
How about enabling windows enabler? If your on Windows 7, you should run it as admin. you need to click on windows enabler, till it shows ON.
Ok, I will try, but this step was not mentioned...
(os is xp sp3)
when I tried the KDZ update I had to run windows enabler, and it was working well, and as I see this tool is also included to root, but this step is missing
Anyway, thanks your reply I will try it
Hello!!
I've recently updated my phone to Official ICS (Korean Ver.) V30I and I had problems installing the recovery.
I could root my phone, its just that I can't install the recovery. I know there are already modified ICS Korean Ver. for p970 but there are still a lot of bugs and battery life is kind a shorter than the official ics.
First, I've used rom manager to install but after boot, ""security error"" came up at boot and cannot even start.
Second, I've also tried using other methods such as programs made by OB devs but still the same problem.
So I would like to ask, if anyone out there has this problem and any solutions to this, please reply.
Have a nice day and thanx.!!

Don't use ROM Coverter! It doesn't put the different bin parts correctly with such a large bin file.
If your using V30I then I'm assuming you have KU5900. Use novasoc's lg extractor to extract the bin file, patch the various .bin files together in numerical order. You can then use novasoc's recovery injector to patch the bin file. Patch with SFT and voila.

How did you root the phone without CWM?
Oh. Thats easy. Just use unlockroot program^google it^ and your phone will be rooted.
Anyhow now p970 users have official ics installed on their phones...can someone please find a way to install cwm ... Cuz as i mentioned above... I still get security error at boot.... And also Ive pretty much used all the methods above and still not working
thanx

thanks for the reply, my friend... i just figured out what to do and was able to bring the phone to living world again. the trick is to put it in "update mode" what is everything but intuitive...
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!
