[TUTORIAL]update firmware through flashing the kdz files - LG Optimus 4X HD

Since i was frustrated with updating to V10f, i've asked so many people to solve my problem...
i'm here in Hong Kong and i haven't got the OTA update for V10f yet..
so i finally find a solution about that
http://forum.xda-developers.com/showthread.php?t=1264289
it's from O2x section but i found that it works for P880 too (great work by felipemadox , not mine:laugh
i just copy it here and for you all easier to know this method
| 1 |
Download these 3 apps: http://www.4shared.com/rar/Re4VCOAS/kdz-udpate.html (the original link is deleted, re-uploaded by RuedasLocas):good:
| 2 |
- Install B2CTools LG
- Extract the KDZ_FW_UPD_EN.zip (ex.: C:\KDZ\)
- Install msxml.msi (located \KDZ)
- Extract WindowsEnabler.zip to the same folder as KDZ (ex.: KDZ\WindowsEnabler)
| 3 |
Run LGMobile update (must be on your desktop) and install the usb drivers
| 4 |
Reebot your O2x in SW Upgrade mode (remove the battery, turn on the device and hold the vol - key)
dont turn the on/off button, just hold down volume and plug the cable in
| 5 |
Open the Windows "Device Manager" > Modems > disable the LGE Mobile USB Modem
| 6 |
Run as administrator KDZ_FW_UPD.exe
| 7 |
- Run as administrator Windows Enabler.exe
- After run the app, an icon will appear on your tray, single-click on the icon util the "ON" text appears over the icon
| 8 |
- Go back to KDZ, locate press on the yellow folder and locate the .kdz file that you want to flash
- In my case, Optimus 2x P990h, the o type must be "3GQCT" and phonemode "DIAG"
| 9 |
- Click on "Launch Software Update" and don't click on anything else
- WAIT util your phone reboots automatically (5-7 min) and unplug the cable
- Dont care about the errorlog, it's normal
If you got only bootloop after flash .kdz, just do a hard reset:
- press and hold [vol -] and [power] until you got the "android recovery figure" and wait until they reboot again.
----------------------------------------------------
tested that root will lose after updating the firmware through this method
p.s. my English isn't good at all, sorry for that

Doesn't the force update to v10f break the radio of the phones in countries where only v10c is available OTA?

leave the battery in!
Else u will get yellow screen

Any singaproe users here?
It seems that after i upgraded to v10f i have problem with whatsapp, fb messenger, wechat not connecting via 3g.
However i can surf and also use the FB app with 3g.

PLEASE INSERT BACK YOUR BATTERY AFTER STEP 5. Or else the upgrade will fail, and you will get an ulgy grainy screen.

With the LG tool, I think no hardreset is performed, so it is useless, if your phone is bricked. So pls change the title to something like: How TO Flash back stock ROM, cause unbricking is a whole other topic

OK, lets do it...
First you'll need the .kdz file. The firmware to flash it. Click here: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10F_00/V10F_00.kdz
Next, the programs, here: http://www.4shared.com/rar/Re4VCOAS/kdz-update.html
Assuming that you already have the LG drivers installed...
1 >>>>> copy the V10F_00.kdz to the folder that you download (kdz-update).
2 >>>>> install "msxml" from the "kdz-update" folder.
3 >>>>> run "Windows Enabler" from the "kdz-update" folder, it should appear an icon on the right/bottom of your screen, if not near the others in the taskbar, you need to click on it and you should see "ON" on that icon.
4 >>>>> run "UpTestEX_mod2_marwin" from the "kdz-update" folder.
On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")
On the field "Version" (at the left) type "V10F_00".
On the field "Select model .dll" browse and select the "P880.dll" from the "kdz-update" folder.
On the field "PhoneMode" select "EMERGENCY".
On the field "Select kdz file" browse and choose the "V10F_00.kdz" that you download and should be in the "kdz-update" folder.
5 >>>>> with your phone "OFF" and the USB cable connected to the PC, press "VOL-" and connect the cable to the phone untill it turns "ON" in "S/W Upgrade".
6 >>>>> Now click on "Start Upgrade" in "UpTestEX_mod2_marwin". As soon as you see some progress in the log, put the battery on the phone, carefull to don't let it drop.
Wait until the phone reboot by it self and it should be all.
Let us know if it worked or not and, or, if you have any other problems.
Good luck!

The phone boots up but stucks at the lg logo. With 'select type: CMDA (smartphone wm) the log stops at '13:41:32 : 3GQCT : wParam = 2001, lParam = 0'. It never says complete. And with 'Select type: 3GQCT (smartphone wm) it gives an unpacking error.
Its very anoying.

Forgot to tell you, everytime you need to use the flash tool you need to close it and restart it again.
That unpacking error is because of temp. files. The program unpack the kdz file to another one where is the .dll and the .dz, doing that twice it uses to have that error.
What RuedasLocas said is correct however this:
On the field "Select type" choose "CDMA - SmartPhone(WM)" (if the flash fails change it to "3GQCT - SmartPhone(WM)")
Isn't. Keep the phone type set to 3GQCT.

@judodave, try first flash the V10A version.
My first flash went wrong and I was going crazy around the V10C and only after I flash with the V10A I was able to re-flash with the V10F.
Maybe it works with you to... at least I hope so.
Here is the link: http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP880/ANLDWH/V10A_00/V10A_00.kdz
I'll flash mine (later of course) just to post a damn video of how I do it.
Good luck once more.

You'll do it. From time to time someone appears with a phone like yours. For sure is something escaping and we just don't figure out what it is.
When we start to do the same thing over and over again, we use to forgot some small procedures.
Don't worry, one of these days you'll make it.

Thanks.. it works. I just upgraded my lg p880 from v10e to v20a two days a go. Then i rooted the device. Works for two days, then it stuck at boot logo after I restarted the device. Do not know why. So far has been disappointed with the battery performance and the sound quality of this device. Hopefully the new v20a can help improve even just a bit:good:

You updated the phone with a different KDZ from where you bought the phone, so you wont receive any OTA updates... nor Lg pC suite and lg mobil tool will give you the update you actually want.
I know this is an old thread but better to ask here than start a new thread... I'm getting the not registered yet error even though I flashed the correct 20B kdz for my phone by checking my IMEI. I mean I know I can just flash kdz's of future versions, I never actually use the OTA feature, but I'm still curious why I'm getting the error.
Two reasons for this error:
1. Different region software you flashed than yours phone
2. Phone is developer edition aka "not for sale", than you need to use .dz not .kdz

Neither of these are the case with my phone. As I said, I flashed the kdz specified in http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=MY_IMEI and it's not a developer edition.

Ok, that is interesting because if you downloaded kdz with your IMEI from official server, than your device is recognized from LG! Did you try to check you phone and software status with official LG Sync software or LGMobile Support Tool!
First you can try to clear cache and factory reset from recovery.
Second If you dont get this error with LGMobile support tool you can try to reflash with phone recovery option and then check via Settings > About Phone > Software Update > Check now for update again.
1. turn off phone, remove battery for few minutes
2. download lg flash tool from lg site, install it
3. in LGmobile Support Tool manually install drivers, need to click install drivers, select your model, wait to finish installation
4. with no battery in phone, hold volume- and in same time connect phone to pc, whait to pc recognize the phone and than put battery back to phone(if you get colored screen try with battery in phone and volume-)
5. in LGmobile Support Tool in Customer support menu select "phone recovery" and do what LGmobile Support Tool ask you to do

Check your device manager, you will see unknown device named LGP880 ( In recovery Mode )
Use AdbDriverInstaller at attached for install Lg driver.
Then Try again adbsideload.

Then,i flash twrp on unlock bootloader brick it again as usual,having try all method without success.
One day i was just pissed off using the flashtool 2014,i didnt attach my phone until when its require me to attach my phone thru Usb and press continue,then i removed my battery put it back,i pressed Volume+ only and plug in usb into my phone,surprisingly download mode instruction came up and i just still hold the volume+ key until i got to download mode proper.The rest is history now bcos since then i have brick my phone almost everyday now.
Note; i always use kitkat kdz 10d as lollipop dont give me desire result.
but if that didnt work,please take it to LG care centre

nope
try flash another kdz if you re on let say v20a you can use kitkat
more if you r on
v10a look for higher version
v20b look for lower version
and always select CSE not normal on flashtool if you brick your phone
