Flash back to stock firmware! Problem! - LG Optimus 4X HD

I'm trying to resell my 4xhd, so I want to reflash the stock firmware from lg on my phone. I have already flashed kdz files a couple of times, but I can't get it to work right now! I'm running cyanogenmod 10.1 and want to flash back to v10f. But everytime I pull my battery and want to go into S/W mode, I get a red screen. When I leave my battery in though, It boots into S/W mode, but the kdz flash program doesn't work.
I just can't figure out how to get it to work. I'm using this threat to flash the kdz files:

How to Flash Stock Rom

WARNING: Internal SD content will be erased
To begin with go here and download the ROM of your country/region
Secondly download smartflash and drivers from here and install them
Now run SmartFlashTool_P990.exe
Turn the phone off,remove the battery and connect the phone to pc via usb while holding down the vol.down button.
Now you should be able to see the software upgrade screen, and COM port of smartflash will change automatically.
Now in smart flash select "ROM Copy D/L"
Make sure that "Normal Mode" is checked and "Erase Cal" is NOT checked
In AP Bin click browser and select the (BIN) file
In CP Bin click browser and select the (FLS) file
Click start, sit back and wait
I'll try to remember next time that I return to stock rom record it and upload it
Here is the video I said i would record
Yes i do it many time and works very good.
The flash take about 7 minutes
I. Thought you had to nvflash to put stock rom back on device? Or is that just if the phone is bricked?

Hello,

Yesterday i did same thing, only i found some different thread. It must be somewhere on nexus 4 forum. I was on PA 3+ and it worked very well. Only remember what you need to go to recovery and clear catch before booting, because in my case i couldn't boot until i wiped catch. And to enter recovery mode. You need to go enter fastboot, when choose recovery, and when you will see "dead android" you need to hold power button and then press (only one time, not hold) volume up and then you will see menu you can release power button. No need to press vol up and vol down. Just vol up, and press it only one time. Yesterday my mistake was then i always was holding power+vol up and phone was always turning off. Maybe this info will help for someone.

this is that thread http://forum.xda-developers.com/showthread.php?t=2010312

It is under step 4.
Is there also a way to just unroot without deleting all data?
All I did was replace the customrecovery.img and installing supersu. Cant I just delete that?
I have a battery problem and I need to send the phone back, but Im afraid they will drop warranty because of me rooting it (only to try to calibrate battery -,- )
And what about 4.3 ?
If you reflash your android device to 4.2.2, will it ask to install the update (4.3?)
So, did anyone tried it? does it works? my friend asks me to unroot his nexus, and i want to be sure, that i'll not kill his device

Tried, and so far it seems like I've bricked mine. When I'm supposed to see a dead Android, I have an exclamation mark instead of the "open stomach Android".
Does this work for returning to stock 4.3?
I created this account just to thank you!
It works wonders! save my life cause my nexus 4 was doomed when I installed Cynogenmod with the Cynogenmod Installer.
My wifi not working. Phone not responding when I receive a call and many more problems! Thanks to your guide I'm able to restore it perfectly.
One small problem when I using this guide is one of the steps require us to type in "4.2UnrootNexus4.zip" (actually just type "4.2UnrootNexus4)

Ice Cream Sandwich Update

Just a head up guys. Official Ice Cream Sandwich came out for Lg optimus 3d, and you can easily get it on your Thrill by using Lg Flash tool found here <http://forum.xda-developers.com/showthread.php?t=1491870>
kdz file is here <http://forum.xda-developers.com/showthread.php?t=2185406> have fun with ice cream sandwich!
ICS
Did you flash this for the thrill? Any extra steps to get it fully working on the thrill?
All you have to do is change the kdz file name to similar formats like other ones
Sent from my LG-P920 using xda app-developers app
ICS
I got it flashed and it works great. Everything is fully functional on the thrill so far that I tried. It is a nice change over GB for sure. If anyone is curious how to flash this, here was my method...
1.) Get the KDZ file from here (http://www.android-files.de/P920V28B_00.kdz) and rename it to V28B_00.kdz.
2.) On this page (http://forum.xda-developers.com/showthread.php?t=1491870) go down to number 3 and set up Lg Flash Tool EXACTLY how it says.
3.) Select the renamed kdz file you just downloaded in the lg flash tool program and let it do it's thing.
4.) On my first bootup it stayed on the bootlogo forever and just would not start up so save yourself some time and do a factory data reset before your first bootup and it will load up fine. The proper way to do a factory hard reset after flashing is to hold VOL DOWN + PWR till it vibrates and it will prompt you to press the power button twice to reset.
Everyone enjoy ICS on their Lg Thrills!
thanks so much!
I am running v20p stock, rooted and unlocked.
I suppose I can directly flash the renamed ics kdz?
And my thrill will be not rooted afyerwards, but still stays unlocked?
Sent from my LG-P925 using xda app-developers app
As long as you follow all the steps above it will flash with no issues. Root and recovery are lost but I think there is a method to get both of them already. I will try to root and recovery later today. As far as staying unlocked after flashing, I am using straight talk so I didn't have to unlock. Hopefully someone else can help you out on that one.

Does that mean the "Software Update" on a stock GB Thrill would install ICS?
Or maybe boot it into "Emergency Mode" (or whatever it is) and using the official LG Tool would work to get ICS without having to do all the smallsrv stuff?
I guess what I'm really asking is, if AT&T officially released ICS, isn't there an easier way to install it?
If you are on stock maybe you can install using the LG Mobile Support Tool. Trying to use that from my ported ICS has messed my phone up though. I'll have to try to rebuild it tonight, hopefully just using the Flash Tool to flash the bin and fls.
I flashed the Korean ICS, hated the bugs, and reverted to GB.
Trying to use the LGMobile Support Tool to install official ICS and it fails. So I guess I'll have to flash the kdz manually.
The Mobile Support Tool appeared to be working for me, until it tried to reboot and I got an "Encryption Unsuccessful" screen.
Now I've used the bin and fls from here - http://forum.xda-developers.com/showthread.php?t=2198069
After flashing the above with LGFlashTool, I still booted into the "Encryption Unsuccessful" screen, but powered down by long-pressing Power, then turning back on into factory reset mode with Volume down + Power. Following the reset, I appear to be running okay now.
Edit: Nevermind, having an issue , the phone won't work with either of the microSDs I have around. First it's saying they need to be formatted so I attempt that. Then it says the card is damaged.

I had the same problem. You need to go to settings - storage and clear both memories. After that, everything is going to be ok. Do you know how to root this official ICS version? (Already tried the adb and unlock root methods to no avail)

I got the KDZ flashed. Running Official unrooted AT&T ICS now.
However, it seems I didn't do a factory reset and didn't NEED to. It's running just fun.
My system ROM is 619MB with 7.38MB free.
I'm wondering if that's normal... That's going to make some things pretty tough. (Guessing unsintalling Gulliver's Travels and that other crap will help)
I did the reset. My system memory is showing 102 MB of Apps (I installed a handful of things already), and 770 MB available.

I meant System ROM, not internal.
And odd, finally rooted, browsing SystemROM with ES File Explorer. Gulliver's not there. Biggest app is Golf and LG Home at 16MB each...
I remember someone made an app to get rid of most of the AT&T crap. That still work for ICS? I remember AT&T Contacts is required. Don't remove that...
Every boot takes a LONG ASS time, about 10 minutes, to scan my media. That's with no SD card inserted. I might do a factory reset.

no problem...
thank you! but that method does not have instructions and does not seem safe enough...
everyone keeps talking about this rom but no one is saying how to root the rom and no one is pointing out the 3D Converter problem, it does not work at all!!! it works the same way as the xbsall port LOL! and when it does, you can't adjust the brightness...:silly:
Its basically the same version as the xbsall port (v30b) but for some reason it cannot be rooted through the same methods...
I did a factory reset, and the phone stopped booting. Bizarre.
Anyways, I wiped everything but system, and reflashed the KDZ. It's booting now.
Then I flashed the ICS bootloader BUT I used the GB CWM v6. The other recoveries didn't seem to flash properly. So I'm stock rooted now. Now to remember what file to change to make the 3D button work as a shutter.
