Need help to unbrick an LG E986 - LG Optimus G Pro

Hello,
I had rooted and then installed free gee app.
Managed to install a cyanogenmod 12 version on my LG but while rebooting i was unable to type my phone pin , the screen just went popping . with another sim card with no code pin , the apps seem to work well ...
I then decided to revert back to a custom rom from LG ; While using LG flash tools, at 98% of the flash, the phone just suddenly went blank.
When i charge there are no lights and it's impossible to get download mode.
I brought the phone to a shop and the technician told that he could not download anything to the phone and was proposing me to send it to "LG" with additional fees without any warranty of recovery.
i have read on the different threads but so far i have not found any solution , all suggestions are welcome
Thanks.

Hello,
When i connect my phone to my windows PC, a device QHSUSB_DLOAD appears but i can't manage to assign a driver to this device though i manage to install the unified LG windows driver.
When i launch LG flash tools, the program is aborted because the phone is not visible.
Looking forward to a repair procedure wit the local LG center.
Thanks for any help.

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.
Next step i try is to flash a firmware in Download mode, but i cant get the Drivers to work... =(
Someone have some hints for me?

Click to expand...
Click to collapse
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

LG G2 D802 bricked - I read threads from XDA and still nothing :(

Hello,
can you please help me bring my LG G2 D802 back to life?
I had problems with GPS on LG G2 D802 4.4.2 so i tried to go to 4.2.2.I had some experiences with flashing from previous phones so I though I will be able to perform also this one.
I followed http://forum.xda-developers.com/showthread.php?t=2797190.
I stopped on 61% on mobile and 53% on tool. Then i used official LG tool, to recovery, but it stopped on 31% or so. Then i used different FW - with this i could get on 100% mobile - but only 89% on LG flash tool. Then I download official LG firmware according IMEI, but unfortunatelly I was again not successful and was not able to get into download menu. When i connected my phone to PC, i got many pop up windows asking to format many various disk on phone.I was not able to get into recovery mode to perform HW reset.
So i decided to to use instructions from: http://forum.xda-developers.com/showthread.php?t=2582142 with help of mine who is Linux expert.
After this I again get only LG logo when i start phone, and im able to go to recovery mode. I also can start HW reset, but it is doing nothing, just showing: performing hw reset. When I connect phone to PC even that it is switched off (it looks like that) it starts and stop on LG logo, but PC cannot see it. Also it sems, it cannot be found under linux as well.
Please help me.
Thank you very much
Tomas

LG G3 D855 Wont boot in Download mode.

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.

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
*The attachments are just PC Screenshots. I was able to install the LGE Android Serial Driver in place of the QSHUSB_DLOAD, but the connection wasn't true.

Success after supersu bootlooping and non recognized usb on g4

Like a lot of people I have the eu version of the h815 and managed to bootloop it after following the garbage methods online for rooting .. I came here for help and found all the methods listed... lg up, lg flashtool 2014 etc.. the problem was that my phone just wasn't recognized by the computer, it charged well but that was it, lg bridge, lg up, lg flashtool.. none could find my phone.. I thought I was doomed to a soft bricked paperweight and even began contemplating the hundreds of pounds needed to purchase a new phone.. however after hours and hours of tinkering I cracked it and now have a working lg g4 again.
first off download and install lg up dll file
then install lg up but don't open yet
find and make sure u download the correct kdz firmware file ( I needed the h81520d file which I downloaded from storage cow as devtesters didn't work for me)
now head to your computer control panel and delete(uninstall) any lg mobile drivers that you see.
connect your phone through usb into download mode and leave connected
once that's done download the old drivers (4.0.4 I believe) and not the newest 4.1.1 or whatever it is now.
then open lg up and hopefully like me you see your recognized phone.
click upgrade (not refurbish) and click bin.. right of bin is the ... symbol.
hit that, choose your kdz file and voila.. let it work its magic..
DAMN IM HAPPY. HOPE THIS CAN HELP SOME OF YOU LIKE IT DID ME.
