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:
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.
Next step i try is to flash a firmware in Download mode, but i cant get the Drivers to work... =(

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?

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
Hello Community,
Yesterday my G3 stucked in a Bootloop without changing anything. Than I wanted to repair it with the LG PC Suite. This failed with the message "Assert" multiple times. Now it stucks in the download mode. Can I repair it? More important are the files on the G3. Is there a way to get them?

Try this:
1) Remove battery
2) Hold down the power button for 30 seconds with the battery out
3) re-insert battery
4) Try turning it on again.
If that doesn't work, do a hard reset. You can find multiple posts on how to do it. Hope this helped!
Maybe I can help somebody with the same problem. I solved the problem with the following steps:
I setted up a new Windows 7 x64 PC. It must be Windows 7!!! No Windows 8 or other shiny things.
Installed the driver
Flashed a compleltely new firmware (.tot) over the old (!) FlashTool.
Hi guys. First, sorry my poor english. I'm Brazilian.
I make a firmware upgrade from LG PC Suite, 4.4 KK to 5.0 L. Problem is, the upgrade failed, and now my LG G3 are stuck in download mode. I try make this upgrade from LG Flash Tool but the problem persists, 65% appears in the screen of LG G3 a message "ASSERT" and reboot to download mode screen. Help, please?

Although I have never come across this, using this site to download the right KDZ and using this thread to flash that KDZ may solve your problems. There is no harm done in trying this and you can be sure that it is the right file.
LG G3 Boot problems after download mode
Hello!
Sorry revive the topic but it was the only one who found a similar problem, after searching lot on google.
I have a LG G3 D855P. Yesterday he went out and restarted many times, but worked for a short time.
I can use the BoardDiag, but when I restore the D855P20C_00.kdz .kdz, to reach 36%, the cell phone goes off and does not return. I need to take the battery cable, so that it returns to the download screen, but still, to get 36% he goes again. Have made sure that the .kdz file works properly.
I followed the tutorial presented in this video.

Hi im new to XDA Developers Forum, i just tried this Solution( http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977 ) and my LG G3 D855. Is in the same state as from User "DonnieDoezoe"
"Totally bricked my phone with these instructions Won't turn on anymore. Tried everything...only shows a trinagle if I connect to usb without battery."
Before i tried this. I had already rooted the LG G3 D855, and after these instructions i tried to reboot into recoveryTWRP( wich i flashed with flashify) i tried to reboot with Quick Boot (Reboot ).
After this my Phone doesnt work anymore and is just like in the state of a blacksreen( the phone is visible as LGE AndroidNet USB Serial Port(COM41), the only thing that shows is a triangle if I connect to usb without battery.
I searched for solutions the whole day and tried to unbrick it with the LGFlashTool by flashing the .tot file and .dll, but wont work because i cant enter to the Download mode.
I Hope some one gives me hint in the right direction on how to fix this problem, would much appreciate it.

After modifying build files failed, G4 bootlooped at starting logo.
Tried to repair it with lg bridge, and it was forced to update to 6.0 v20c.
Flashed it with v10fkdz(5.1), and the error message was shown:"Error Code=0x2000, Can't decide current device mode."
Can anybody help me to solve the problem?
I think you broke your download mode; sadly, it is the only mode that you can flash via LG Bridge and LG UP. If you have an unlocked bootloader, you can flash an image through fastboot. As for me, I can't flash on either of those programs since I also broke my download mode and I have a locked bootloader. Otherwise stated, I have a hard bricked device. Waiting for some possible new program to fix my device
I tried on 3 different PCs, and another available G4 device.
The problem is still there.
I don't know why,
but after reinstall LGUP, downgrade of my phone is OK.
Thx guys
