if any one is able to help just try to give me a step by step guide or just pm me, i will thank you so much

Did you press and hold both the Volume Up / Down buttons before executing the .bat file?
Also, check that Windows recognizes your phone as an APX device before trying to run the bat file.

Press vol down button when you insert the usb cable.
Then you get a s/w upgrade screen.
Open smartflash tool and just try to reflash

Unless the H matters it's obviously caused by not following all instructions

What version of Windows?
What version of USB Drivers? Try newer drivers.
Bootloader isn't be changed by flashing ROMs in CWM. ROMs only need to change from boot partition and upwards since thats all they need to change.

What do you mean by software mode ? You mean when the phone is wake up and i'm on Lg Home ? Because when I do it smartflash doesn't find my phone, but windows yes. I tried also to use the SOS recovery mode of B2C but it said that my software version was up to date so it did nothing.

I tried on windows 8 and 7. On twice I downloaded the newest driver 3.7.
I think a problem of bootloader because I flash the old version of V28c, with the .bin and .fls which had CMW inside, It was befor they release the .zip version. It's rewrite the bootloader no ?. And also because my phone doesn't wake up when I push on power button on the V28c, V20G, and CM10. I can only flash it because of rom manager and nandroid backup.
Thanks for help

Solved
After 2 day on this @"#[email protected]# phone, I find a solution work only on widows 7:
With the usb recognition I succed with this protocole,
1) Uninstall the Lg driver
2) Install the driver with B2C
3) Put the phone in S/W mode with the battery windows will say that it's not recognized,
4) Unplug the phone It will stay on S/W mode
5) Reboot Windows 7, and as soon as the desktop finish to load plug your phone
And miracle it's work. Sometime you need to do it 2,3, or 10 times.
Concerning the power bouton it still desn't work on V10A, V20N.... So I think it's broken, so I will exchange it with my operator.
Thank a lot for people who gave me some time.

[Q] How can you flash a brick when your pc won't recognise your device

Hi there so I today truied to update to Eagles Blood custom Rom using Rom Manager to flash the new rom onto my O2x. The rom supposedly installed correctly but then when it booted it just gets to the unlock screen you unlock it then it reboots after a couple of seconds.
I can't get into recovery mode by the usual power on volume down technique as this just results in the phone continuing to load. I have tried different combos of power button reboots with volume button up, volume down and both together none work the only difference is that one of those results in just the LG logo rebooting.
I read a few posts about using nvflash or even the lg recovery tool using imei number etc but still no dice basically when I do the connect to the pc with both volume buttons pressed and the battery out it connects but doesn't recognise the device. I try the device manager and updating or removing the driver but regardless of how and what I try it either tells me it's using the most current driver or that no driver is actually installed.
This the same when using NV Flash i can't apx drivers installed and the device if I try to skip that step and go straight to the flash.bat command i just get usb device not found or connected or something like that.
Please help i am willing to try anyrhing and i really don't have the money for a new phone. I only have to get it working long enough or far enough so i can reinstall my backup i did before attempting the rom install this morning.

try connecting to different usb port(I suggest the backport of your PC)
and if that didn't work, must be a faulty cable.

Unfortunately the cable is fine as if I'm not holding the power or volume keys I'm charging the batteries. I'm thinking there's something wrong with windows and the way it detects it possibly as i've trawled a fair amount of forums and tried a lot of what others have managed to get working with exception to someone else who had the same problem but couldn't get a resolution (that he posted about).

May be your USB port was broken.

Have you actually installed the apx drivers required for nvflash to work?

you're not on Hard Brick, right?
can you try Smartflashing?
you need to install LG united drivers first.

APX won't install
So the problem is that my PC will pick up the unknown device. But it will not allow the install of the drivers. I can install the LG universal driver. The phone will connect as a unknown device only with error code 43 (device has been stopped) you try installing the APX drivers and the install of those drivers fail with error code 10 (can't start the device) this happens on both my stuffed phone and the brand new replacement so I am at a loss I have tried this on Windows 7 pc and also a Win 7 laptop (64 bit and 32 bit respectively).
The whole affair is frustrating as hell as I an't get my new O2x recognised either I can't root that to put my nandroid backup on and I am stuck on Froyo that I can't seem to root at all or even use lg update tool to update it to the latest stock firmware.

WHat about rooting apps
So with the obvious ways not working are there any actual apps I can install on my phone that will root it that way I am certain this is how I did it on my first O2x just can't remember what the name of the app was. So if anyone has apps or links to apps that may do this and or do do this please post back.

Have you actually tried a different USB cable? I notice you said the cable charges the phone, but this doesn't mean that other cores/pins other than the ones used for charging aren't damaged.

different windows and different drivers
My suggestion would be try it on some other computer and different drivers. Or on same computer but reinstall Windows and ofc different drivers.
I'm suggesting this because I had experienced some what similar things on LG phones.

Help! 4x hd CWM bootloop error! Flashed wrong CWM.

Hello I have an unlocked Lg optimus 4x hd software version 4.1.2 JB. I recently successfully rooted it but CWM said there wasn't one available for my phone on the rom manager app so i found one. I would post a direct link to it but apparently im not allowed to yet.
I realised that this was realised almost a year ago after the fact, this probably is what messed my phone up.
I installed it and ran it, when my phone rebooted it was stuck in a boot-loop. I can still access the default android recovery screen and I tried hard resets and clearing the caches but I'm still stuck on the LG logo. My computer still says that its installing drivers when i plug the phone in but it won't let me do any thing. I have looked around the forums and the solutions i found aren't helping me. Any help would be appreciated.

Adb sideload

Access the android recovery screen, then select adb sideload.
if you can access adb mode, you can use all in one tools.

How do I do that. I feel like I've tried it before. CWM didn't load properly on my phone so I cant do anything involving the use of it.

You just need to be able to get in S/W Mode by pressing "Vol- & connect to PC".
For a better flash try to use LGFlash Tool, look here:

great it looks like im nearly there but where you saw three ports active and one actually downloading i only saw one active but it wasn't downloading, i feel as if though it could work i just need a little more help. Sorry if this is wasting your time...

simple, run windows enabler to ON, connect phone in S/W mode, go to device manager -- modems --- LG xxxxx *13 ... and the number is the port ... for me i have 13 port selected .. or you can try one by one ... if one fail ( RED --- FAIL TO OPEN) then try another ...

Thank you everyone!!
It worked thank you guys soo much!!

Hi there,
I flashed the wrong cwm as well on my gf phone. (she's going to kill me)
Anyway, the All-In-One tool does'nt help me. I can perform the root (which is useless, because I cant even boot) but I cannot anything. I think it's because no sd is mounted.
Code:
Choose The Number :-7
Now connect your phone with "Debugging" enabled .
Drücken Sie eine beliebige Taste . . .
Copying files ,, Please wait ...
failed to copy 'O4X_OR_R.img' to '/mnt/sdcard/O4X_OR_R.img': No such file or dir
ectory
sh: cat: /mnt/sdcard/O4X_OR_R.img: No such file or directory
rm failed for /mnt/sdcard/O4X_OR_R.img, No such file or directory
I can't even boot into the S/W mode. I just get a grey (or sometimes blue) screen.
Please help!

try to take the battery out plug the phone with a cable on your computer. Insert battery again. Flash firmware
edit: it seems like your all in one tool doesn't find the image.

flash a firmware using LG-KDZ-UPDATE-TOOLS. Search them in google,
Follow instructions found in the internet. I can give you a link but its in german. There is probably an english equivalent here somehwere.

[Q] How to unbrick my 4X - a question of life and death!

I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.

If none of those things that you said doesnt work, as last resort you should try this
http://forum.xda-developers.com/optimus-4x-hd/general/s-stuck-rescue-ultimate-rescue-guide-t3012444

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.

I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit

I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer
Click to expand...
Click to collapse
My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[
