This is the tutorial you musto follow:
http://forum.xda-developers.com/showthread.php?t=1942836
When choosing KDZ file, use the latest for your country, from here:
http://lg-phone-firmware.com/index.php?id_mod=2
PS: Just noticed there is no Sweden ROM there, just use EUROPE OPEN.

Ok I have done this..but it installed CWM recovery and also in Android Gingerbread it gives me 0 mb internal storage, even after factory reset and storage format...

Whats the diffrence between a .kdz and a bin file? I downloaded a kdz file from ur second link but in the unbrick method in the first link its all about bin files..

A KDZ file includes a rom (BIN file) and a baseband (FLS file).
If you flash a rom (BIN file), you will need to also flash a compatible baseband (FLS file).

My phone is stuck in a bootloop with LG logo and LG animation...i try to enter the Recovery with 3D+Volume down and Power button until vibration....but nothing is happening....only LG logo appears then dissappears----

Now it entered. But there was no vibration and i needed to press volume up or down for the screen to appear....strange :S

Hey, try this tutorial with flashtool its very easy, you have to flash the kdz you find everything here

I want some help. My question is, what is download mode? what is the difference between OMAPBOOT DOWNLOAD MODE and NORMAL DOWNLOAD MODE, and how do we get there.
Also, I am from India, so I have to flash the ICS .bin file from XBSA404.rar and the .fls file from a baseband that works with ICS in India. Is this correct?
The reason for my asking is that I tried ICS XBSA404.rar for P920 on my P920, there was no network, so I got back to GB, but I lost IMEI. Since then I have been trying restore IMEI to no avail.
Now my PC got conked off, so I will install XP and try again (I was on WIN7).
I don't want to take any risks, hence these queries, even though I know that these are rudimentary questions.
These questions are open to every one, so anyone who can help me understand, I will be grateful.

No u flash both Fls and bin from xbsa Rom but your baseband should be working just check out the basebands thread made by xbsall

so i have only one question is it official
you know i don't want to mess with my phone or put it a custom rom
i want it to be officially updated to ics
also every time i update it tells me emergency mode if you can please tell me how to disable it
If you don't install the rom, the v28B normal partitions .bin file is official ICS, only rooted with custom recovery. If you don't want that, instead install a .bin that is pure stock ICS. Or, there is a tutorial for installing a .kdz file using a different tool.
It all depends how you want to do it.

ok well i want it official
and one more question i have lg p920 so if i installed this rom will it erase the apps like 3d gallery 3d converter 3d space ??
The v28B ICS is official + root.Stock v28B ICS has all stock apps + a root app or two. If you look at the link to XBSA rom, it will list what apps are in there. I just wrote this installation guide, not the rom. VR3D has the 3D apps. I think XBSA 8 does also, but I don't remember. Either way, having root lets you install whatever you want.
If you do it, do it carefully. And if you have 10 posts you can ask me questions over there.
Please help
Hi,
I tried today to update my p920 thru PC to ICS.
After more than ten unsuccessful tries I wanted to try from the begining but with the phone factory reseted.
After reseted my phone, it displays "not enough space. clean ...."
In settings - applications - manage aplications does not show as usualy the mb used and mb free.
In settings - SD card&phone storage settings shows total and available space for internal and esternal SD but ...
"not available" for internal storage.
What can I do?
PLEASE HELP.
What did you do to cause that?
If you are following my tutorial you missed something. Read all details.
If you installed xbsall's v28B large, you need to erase internal memory.
But I don't know what you did. Please explain.

Nothing else than I said above.
- connected the phone to pc
- started LG mobile support tool
- When showed there is an update available I pressed the red button "start Update"
- Then try and try. disconnected the usb cable and battery as the LG Support Tool requested ... still same message:"problem in conection to your phone. Even if seconds ago recognized it.Didnt get further than 40% on analizing tab.
Then the same message: "there is a problem conectic to your phone..."
- then I thought to perform a factory reset.
Pressed the tab got me to the bootloader mode where I wiped the cache and dalvik and pressed factory reset.
Pressed the Reboot tab. The phone rebooted normaly but when I tryed to download fx explorer I got the message with no enough space ....
That is all.
Ok, it sounds like possible error in flash. You might try erasing internal memory. Or redoing with LG Mobile Support tool, but I have had trouble using it. Just going from between Froyo and GB was a real pain. It took about 3 tries to get it to work, following LG's instruction exactly.
You can try my tutorial, it should be linked some posts up. It uses LG Flash Tool, not the other one. Or there are other tutorials in the General section that use other tools.
I don't use LG Mobile Support tool.

Same here ...
About 3 tries to get from froyo to GB.
Would you be so kind to tell me exactly what tutorial of yours to try?
And also what soft I need to download for pc since the phone doesnt let me to install anything.
What you mean by "erasing internal memory" ... how can I do that?
Thank you.
First I'd try Mobile Update again to see if redoing it fixes it. Then I mean go into Android system settings/storage/internal memory/erase and see if it fixes it (back up your stuff to pc first, if you can).

Since your last answer I tried an tried with LG mobile support.
Nothing.
From more than 40 times, on 2 times passed 40% on Analyzing TAB and it said my phone has the last software.
LAYER.
The rest of times didnt pass 40%
I tried to erase internal memory but it didnt show the tab "erase" only 0, 00 mb available.
Your tutorial seems pretty hard to me so ... maybe there is somethin I can do from CWM where it takes me after pressing "factory reset"
THANK YOU for your time.
PLEASE HELP.

If you don't want to learn to flash and have CWM, you could install ics by doing 1, 2 (choose 1 option in part 2) and maybe 3 here:
http://forum.xda-developers.com/showthread.php?p=39130435
I have NOT tried it that way and I don't know if it will fix your problem. Plus, if you can't use storage I don't know how you will access the .zip(s) in CWM, unless you can get to it in there somehow.
If you do ending up needing to flash, my tutorial is about as clear as you will get as far as LG Flash Tool.

Need KDZ file

Hello I bricked my device while trying to switch baseband with LGMDP. Flahsed NightlyFourE and CM7 had no service so tried to change baseband.
The process in LGMDP was taking forever, screen wrote "timeout" and the progress bar wasn't moving.
I want to restore my phone using KDZ but all the links to the kdz files on LG website are dead.
Does anyone have a working KDZ file?
Thanks you all

How to flash ROM KDZ Method
First off I`d like to THANK @quangnhut123 for making a new way & easy way to flash the KDZ Method!!
For Any Reason It does not work for you here is the OLD Hard KDZ Method
http://hunterspad.com/?page_id=33
1). Download all The Files Below!
1) Firmware Files
Firmwares are here
2) Download LG Drivers
3) Download LG Flash Tool 2014 tool and extract
4) Enter to Download Mode and plug USB into your PC
To enter download mode
A) Turn off your phone
B) HOLD + and - together
C) Connect to USB (do not press Power button)
5) Run LGFlashTool2014.exe and do as following pictures :
(If you cannot run LGFlashTool2014.exe, please install Visual C++ Runtime Library) - VC_RedistInstaller.exe
Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
No need to choose desired language, it automatically change to English as a default setting.
Wait until 100% to complete !
.TOT file flashing method
TOT method gets error sometimes . Edited and deleted
Change KDZ to .TOT
Before starting please download the attachment
Instructions:
1)Have to put the exe and kdz rom in same folder and execute the program, it shows a cmd window asking which kdz to convert. Type number and tap enter.
2)Then it does the extraction of kdz, cab and wdb, merge bin files and clean up. At the end it ask for patch bin file with CWM.(Do not flash CWM it is for P970 which is not VU 2 )
3)Before typing "n" copy .dll file somewhere (important)
type "n" (without quotes) and tap enter conversion has end. Have to tap any key to close cmd window.
4)You will have .TOT file in a folder(important)
After that you have a folder named as kdz with bin and fls to flash with smartflashtool.

Well there is not much.
You have root and install recovery for 4.1.2 (downgrade if you are on 4.4.2) then install the zip that has root and recovery
Here is the link
If you are not interested in recovery thanks to geohot there is an tethered root called towelroot and just click the lyambda ICON.
To activate the root just
open the app
make it ra1n
download superuser from any market
use rooted application (grant root premission)
after reboot root will be gone so you will make it rain again
Xposed and other root applications are working flawelessy
Is the stock ROM fully English?
I have a LG Optimus Vu II (F200L), which came with a weird firmware that has a lot of stuff in korean. Now I'm not sure if this is the official ROM or not. But it doesn't seem very "OFFICIAL" to me and I think it's already rooted (that's weird cause I've never seen a brand new phone which comes pre-rooted). I played around with the settings a lot, to change the language to english completely, but some of the things still come in korean. This is a pretty good phone but the weird korean stuff ruins it.
So, my question is, does the official stock firmware (for which you gave the links in the first post) have everything in english? I don't want any root or custom ROMS or anything. I just want a full english language interface.
And which method should I use for flashing? The first one seems quite simple, but will it work if I'm flashing a stock ROM over a custom rooted one?
EDIT: I tried using the first method to flash the .kdz file onto my Vu II, after connecting it to my PC in download mode, but half-way through the flashing process, it gives an error "Connection to server failed. Try again in a moment." This happened 4 times. Any suggestions?
EDIT AGAIN: Managed to flash the ROM successfully, just had to disconnect from the internet haha. But ah! Even this is partly Korean! So, I guess there is no international version of the official ROM for this phone? Oh well, time to get rid of it.
try the korean sites
try the korean sites for custom roms and stuff. just google for vu2 sonyue or vu2 lgviet.
these sites have quite a few roms for this handset. all u have to translate the pages to english. also u have to be fluent with the flashing process.
pm me if u want to know more.

Yes this is the STOCK firmware. This phone is only korean branding so you will get a lot of korean stuff. You can delete some of that stuff by using Titanium backup which need root
