LG Optimus 4x HD (LGP880) bricked and imei stuck

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:

Bootloop after Xposed install, Hard Reset not working

Hi there,
i rooted my G3 using Towelroot and all worked fine.
Today i installed the actual Version Xposed Framework and after rebooting it entered a Bootloop.
So i tried to Hard Reset my G3 but when i confirm it the Android with the Gaers show up for a second and then my G3 keeps showing the LG Logo for a few Minutes till i disassamble the Battery.

Have you choosen ART modality?

If i would say "what the hell is that" ... would u slap me?
No.. i dont have chosen that..
Bigger problem is that i dont get any usb driver working for firmware update in Download mode.. =(

OK... i managed to get the drivers working.
But further Problem ist now that im not able to flash anything on my device...
Neither the TOT Method, nor updating with the Original LG Support Tool is working...
Support Tool tells me my Model Number and that my Version is most actual.
If i update anyway it stucks at 4% and tell me it cant connect.
TOT Tool tells me that my Version Number is not correct... but it is..
With the KDZ Update Tool it stucks at 4% like the Original method.

Same problem here
Any one can help us?

Solution
Hi there,
the Problem was my PC...
I was on a Windows 8.1 64bit.
Switched to a Win7-PC and all is working fine.
You should try to use the Original LG cable, or another "Original" Cable and connect it to a USB-Port on the Back of your PC (directly to the Mainboard)
On a blank Win 7:
- I installed the LG PC Suite
- Updated the PC Suite
- Connected my LG in Download Mode
- Let the PC install all drivers,
- Disconnected the Phone
- Downloaded the actual LG Mobile Support Tool
- Let the Support tool do the work
After this i got my first OTA Update and its working like a charme

Need help with LG G2 Bad Flash

I have the LG G2 Sprint version using pageplus. I tried to flash CM12 rom using twrp in an attemt to install lollipop on my rooted phone. After reboot it hangs at LG logo. I can't use buttons to hard reset, but I can back into twrm. The restore option shows no files available, and the folder that held the CM12 is now empty. In fact, using the file explorer, all folders are empty. I tried using LG Flash tool to reinstall the stock ToT, but my computer will no longer show the phone as a drive or device. It will make the noise when connected and say it's installing drivers for LG G2, but when it is finished...nothing.
Is there anything that anyone can think of to help me revive my phone?

LG Optimus F3 - VM/Sprint/VW - All Thread

Moderators- can a user create a thread category? I know its not new but this phone has enough posts to fill it, a heading. Thanx

LG Optimus F3 Bricked, No Boot At All
Hi all, and thanks in advance for any help received. Long story short I just bought a VM LG Optimus F3 and bricked it within an hour. Im not new to rooting, but not Dev-level either, I prepared the folders and files necessary while I waited for the phone to be delivered. Ran a root tool but it only rooted the device, no recovery partition was changed or flashed, and on rebooting into recovery, brick. Just FYI, RomToolbox told me I had TWRP installed.
With different forums and information posted I've tried entering DL Mode, running the Flash Tool, and ADB'ing the phone ( debugging Was selected prior to my screw up), but the most I get is a colored Home button sometimes. Help PLEASE.. thanx!
Also on Win10 x64

D855 - Flashed wrong baseband... red and blue flashing LEDs

Hey guys,
so I recently decided to update my LG G3 (D855 EU) from CM12.1 to CM13, but it just told me that I have the wrong baseband.
So I flashed a baseband someone recommended on reddit/here (xdabbeb_vs98535b_bootstack.zip) which apparently wasn't the right one.
So I just rebooted (bad idea), now my phones LEDs are just flashing red and blue right after the LG logo.
I tried the KDZ and the TOT method, but both of them failed because they can't seem to find the device!
LGUP just shows "Device Unknown". LG FlashTool never goes past READY!! And LG FlashTool 2014 cannot connect to the device.
I installed every driver I could find. (LG United Mobile Driver, LG Mobile Support tool and even LG PC Suite)
I tried uninstalling the device a couple of times, but every time it just can't seem to find any drivers for them automatically.
So installed them manually. I have "LG Electronics Inc." and "LG Electronics, Inc.". Only the first one worked, the second only gave me an Error 10 in Device-Manager (Device cannot be started)
The device is already configured as COM41. I also tried COM 4 and COM 5 for the flash tool 2014 and LGUP.
I tried everything on multiple computers and I even set up a VM to try it on Win7!
Please help me! I don't care about my data, I just want my phone back

I'm using Windows 10, but I also tried it on Windows 7.
Because Windows 7 seems to work better with the tools

Google LG G3 drivers. I had the same problem with my G3 and i got drivers for the G3 only,installed them and was then able to use LG Flash atool 2014.
Thing is if using Win 10 you need to disable Driver Certification or 10 will not recognize the phone for upgrading etc. Also once disabled they will need to be done each time you start up from cold as Win 10 does not retain the setting when switched off.

I tried that already, but it can never find any drivers... I disabled Driver Certification but nothing changed.

Just a quick question... Are the Drivers supposed to be by "LG Electronics Inc." or "LG Electronics, Inc." because it is showing both of them and I really don't know which one to choose.
(I can see both of them if I manually select a driver)

hi all!
i have the same problem and didnt even got to the PC part.. my phone (lg g3 d855) just flashes red and blue lights.
if you can please explain to me (step by step) what i should do to make it work again..
i installed lolipop cm12 (had stock kitkat by LG before) on it and it worked fine but the whole purpose was to get the MM cm13 so thats when i flashed 35b instead of 21c as requested.
please help me, thank you all.
