LG Optimus 4x HD (LGP880) bricked and imei stuck - Upgrading, Modifying and Unlocking

Hello,
I've got a big problem.
My Android phone, LG Optimus 4x HD, won't boot up anymore.
When the LG logo comes up, the phone won't do anything.
My phone is rooted en has an unlocked bootloader. The second problem (actually the first) is that he don't see his IMEI number anymore (and Mac adress). So I can't do a phone call anymore or use the internet. I tried to install twrp recovery and than it went wrong.
I tried to restore the phone through: LG PC Suite, LG Flashtool(error message: IMEINOTACTIVE), KDZ flash but nothing worked.
I tried it about twenty times, and intall en uninstall LG drivers but it didn't help.
I've also tried to install CWM Recovery through ADB in the recovery menu but he can't acces his internal memory or something.
I can access the bootmenu of LG and the software upgrade menu.
I hope someone can help me with this problem(s)!
Thanks in advance:good:

Unbricking LG Optimus G E971

Hi,
I recently got the LG Optimus G E971 on Rogers in Canada and it is a fantastic device. Since I did not like LG's Custom Android OS, I wanted to install the stock Android. Therefore I chose the AOSP 4.2.1 for LG Optimus G, but before getting there I had to root the phone and unlock the Bootloader.
After successfully rooting the phone and unlocking the bootloader, I decided it was time for me to flash the ROM by following this guide:
http://forum.xda-developers.com/showthread.php?t=2116649
Once I got to Recovery Mode in the ClockWorkMod Recovery, I wiped everything according to the instructions;however, I have forgotten to put the disk images to Flash.
Now I am stuck at the LG Boot Logo, though I am able to access the Recovery mode and FastBoot mode by turning the phone on and holding Volume Up + Down. However, I am unable to access the phone's storage because it is not recognized on the computer as a USB Mass Storage anymore.
I have tried putting it into Download Mode and using KDZ_FW_UPD.exe to restore it back to Stock, but it kept bringing back to the FastBoot. I also tried using the LGNPST with LGE971AT-00-V10d-RGS-CA-OCT-24-2012+0, renaming .tot to .bin, though it gives me an error before it can even begin.
Does anyone know how I can get this back to the stock firmware?
If you need any extra details i.e. Screenshots or picture of the phone, please tell me!
Thanks,
Oakcapy

OK, my problem was Windows 8.1... The phone is well recognized by LG Tool under W7, but now I have another major problem, at the last step, when the tool begins to flash the rom, it goes until 5% and then this popup box blocks the flash "battery level is low and upgrade is unavailable"
I have reload fully my battery (I plugged it into the G PRO dock)... still the same message.
Any help please ?
Did you manage to resolve the issue? I am just having the very same problem and a bit lost and cannot risk flashing anything right now.

Please help me since i do not have another phone and can't afford to buy a new one...
You'll have to restore your phone with LG Flash Tool 2014
First off go here, replacing <yourimei> with your actual imei (just numbers, nothing else), it'll spit out a bunch of text including an address with the kdz. (You'll find your imei on your phone box. There's no other way for you to find out, because your phone is soft bricked.)
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=<yourimei>
Then follow this guide: http://forum.xda-developers.com/showthread.php?t=2797190
Hope this helps.

Bricked!!! Help me out please!

I'm a newbie and don't know much about phones. I rooted my phone for the very first time and was about to install CWM.
I've an LG Optimus G Pro F 240K.
I downloaded an app namely Flash Optimus G in .apk form and installed it on my phone. I tapped on Flash and the screen read "SUCCESS! Now re-boot you phone into recovery." I tapped Reboot into recovery. That time and now, i'm numbed. The phone isn't responding at all. I'm using Windows 10 Pro. In device manager, an exclaimed mark icon gets visible when i connect my phone.
The device name is QHSUSB_DLOAD.
I've downloaded official stock firmware 4.4.2 kitkat. When i use LG Flash Tool, it says your device isn't connected to your computer.
What should i do???

Or downgrade to Windows 8.1 and then restore by KDZ
qhsusb_dload means you´re in qualcomm mode, and also means that you´ve killed phone boot. from what I know, only medusa and riff boxes can fix it.
