[TUTORIAL]Update firmware through flashing the kdz files( With Picture )Step by Step

esag21 · Dec 28, 2012

Here we go ( Read all instruction and comment before start flashing ) :

1 ) Download these 3 apps: http://www.4shared.com/rar/Re4VCOAS/kdz- udpate.htm (the original link is deleted, re-uploaded by RuedasLocas)
To get KDZ file you can find it here : http://lg-phone-firmware.com/index.php?id_mod=15

2 ) Once downloads complete Extract the file (ex.: C:\KDZ\) and u will get folder like this :-

3) Install B2CTools LG ( B2CAppSetup.exe ) this file is located on the folder that yr extract before .

4) Run LGMobile update (must be on your desktop) and install the usb drivers .

5 ) Turn off yr device and remove the battery .

6 ) Now just hold down vol - key ( hold hold hold dont release !!!! ) and plug the USB cable until you get screen like this :-

7 ) Wait for while due to yr computer will install some driver . Once the install is complete find "Device Manager" > Modems > disable the LGE Mobile USB Modem on yr computer ( me using win 7 -----> start ---> computer ---> right click / and you can find device manager )

8) Run as administrator KDZ_FW_UPD.exe ( file located at step no 2 )

9) - Run as administrator Windows Enabler.exe ( file located at step no 2 ) . After run the app, an icon will appear on your tray, single-click on the icon util the "ON" text appears over the icon like this :-

10 ) Go back to KDZ, locate press on the yellow folder and locate the .kdz file that you want to flash

11) Click on "Launch Software Update"

12 ) Please see below picture !! Very important !!!! Now standby to put yr battery back !!!!!!
When the log start to run, put the battery back on. ( thanks to RuedasLocas ) im copy from u

13 ) - WAIT until your phone reboots automatically and unplug the cable , ( ALL IS DONE ) please check yr firmware on yr phone ....
- 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.

INFO !
When you tried to update yr LG Optimus 4x HD , the error comes " Your Device Is Not Registered Yet "
That because you're using different version than the original country and you wont receive OTA update .
The only way to get it back is by using LG software or KDZ method and install yr country's firmware.

I hope this will help for those want to update firmware via KDS
And thanks to RuedasLocas because always help if we in trouble .. Thanks bro ..............

Before start flashing please do backup first ( yr photos , Videos , music on yr SD card )
For clean install wipe yr data / factory reset !!!

Did you really need to make another thread but with pics? Honestly, I think reading is enough.

Even with pictures will appear someone with some problem...

Normal, even cause there are other settings available and required to specific kind of flashes.

The work is very good specially the intention.

Thanks @esag21 :good:

I think no need to remove battery
Still work even skip step 5

elfen.lied · Dec 28, 2012

I updated my firmware , just by downloading the update software and following the instructions on the screen. Didn't disable modem and didn't remove battery. As far as I can see everything works fine. Battery is a bit crazy sometimes. One night I left it 100% before I went to sleep and found it at 100% in the morning and the other night I lost around 4% which is still ok.

I do get tiny lags in some games sometimes, not sure if I'm imagining it or not, but it didn't happen before, now I'm not sure if it's bcs I didn't remove the battery or disabled modem as you described.

Also is it possible for me to reflash from v10h to v10h but now disabling modem and removing battery?

and will I get anything by doing that. Since I don't seem to be having any issues right now as far as I understand android

Also why go through all that procedure of removing the battery and disabling the modem when the simple version plug and follow instructions works as well? At least it did for me.

Some program behavior depends on your own computer setting, programs and drivers. Don't mean that the tutorial is wrong cause it's not. Your all welcome to post helpful hints but please, don't flood with minor issues. Thanks

Well in order to be helpful here's what I did:

1. Installed LGMobile Support Tool (I'm sure you can google it

)
2. Run the program and click on Install USB Driver.
3. After the driver finished downloading and installing, close the LGMobile Support Tool and plug in your phone via USB cable.
4. Now run LGMobile Support Tool again and it will start checking your device. At this time I also changed my Country by going to Options & Help ----> Country and Language.
5. After that I clicked on START UPDATING and followed the instructions.

I'd describe instructions in detail, but since my phone is already updated, the START UPDATING button is greyed out.

After the process has finished phone reboots into a new firmware which you can confirm in settings and the Tool itself confirms it.

Hope this helps!
