So I have bought a L7 and when I have it the phone is not working, the seller doesnt want to take my money back so I need help with this :S!
No appears to do anything when connected to charger
No led
No vibrates
No emergency mode
When I connect it to my PC it recognizes it as QHSUSB_DLOAD, but neither KDZ or LG update program recognize it :S!!
Someone know how to reinstall OS I think is software issue but I dont know how fix it
Thanks!
Try following the instruction I got from a website.
What is 'qhsusb_dolad' ?It is the situation when you can't boot into your phone,recovery mode and any other visible interface. When you connected your phone to the PC, the LED will flash and your PC will show that they were searching for the drivers needed(win7/8) but they couldn't find .......If it is commom for you to remove the battery when the phone did not shutdown completely or when you ran into 'No-Response' , as time goes by ,it will be inevitable that you come across the 'QHSUSB_DLOAD' situation .
But from now on ,you needn't worry about that for I have found a way out.
Tools needed:
Hardware: A PC running XP and higher (win7/8 recommended) and your usb cable
Software : MIflash and MIAssistent and a certain mi update rom(It is a *.exe file---fastboot file)
Steps :
1. Install the first two softwares described above(Run as administrator) in your PC (You need to disable the enforcement of digital signature while on win8 in the advanced startup (press 7 or F7)
2.Boot into fastboot mode(you just need to do with your two buttons and usually you cann't see the interface for your screen just won't show in this situation) before connecting to PC
3.Connect you MI2/S to your PC via the usb cable and the pc will recongnise it in the device manager panel(if not, update its driver in the unknown device---qhsusb_dload)
4.Open the miflash and click fresh to load your phone's serial number
5.Flash the update rom(the self-extracted-to folder) into your phone and reboot .
Explanations:
Miassistant contains the 'qhsusb_dload' driver for any phone and it enables the PC(Miflash) to recongnise your CPU serial which is the key part of updating by wire.
Tips:
Try this with your other phone, I believe it will work ,too.
I'm supposed to just copy/paste the link.. but the protocol won't let me since I still don't have more than 10 posts. I just want to help. Try this
I have been trying to follow the flashing instructions for my LG G2 D802 from here
http://forum.xda-developers.com/showthread.php?t=2432476
When I click Upgrade Start from the Normal Web Upgrade Test button I get this error message.
Please Install CSMG B2C Client Tool
Select Tool -> B2C client setup menu
Can someone tell me where iam going wrong and what this means.
Thanks.

Has no one else had this problem before? Is there an alternate way of flashing a kdz file?
Go to tool on the site and download that b2c package. I suppose.

read the readme in the root folder. It says something about installing, then launch window something and then start from the tutorial again.
They skipped the part on how to install it lol.
Right, I have installed it now, I am using a different computer as well.
I have run into another problem now. It gets to about 15% on the phone update window and then says connect phone to usb cable.
I have looked at this picture here http://forum.xda-developers.com/picture.php?albumid=8677&pictureid=32161 and compared my device
manager. I have the top item in modems but not the LG Mobile Composite USB device. The drivers all said they installed correctly. Anyone
know how to fix this?
Thanks

This happened to me, stuck at 15% using the flash tool. I put everything I needed on a thumb drive (lg drivers, B2C setup,flash tool, .kdz file)and used another PC. Worked smoothly on a different machine.

Anyone else have any ides on this?
I have installed everything on another computer now so this is the 3rd one and I am still getting the connection issues.
If I plug the phone in via usb I can see it in windows explorer and transfer files but LgFlashTools keeps coming up that it is not connected.
It goes through a series of 3 events.
_IsConnectedPhone Call
_isConnectedPhone(0)
0 - NotConnected
1 - Normal Connect Success
2 - Emergency Connect Success
Have I not done something right or have I missed some settings in the phone.
I am using these instructions http://forum.xda-developers.com/showthread.php?t=2085344
Any suggestions appreciated
I would try just the lg tool from lg website, download mode, then update recovery.
that should get you the latest lg rom for your device

I downloaded the tool from the LG website but it just hangs on installation.
Is there no one that has seen my connection issue before?
My original problem stems from a wrong kdz being installed previously, I have a 32GB phone that reports 16GB.
I have but different situation
I tried various, reinstalling drivers, reboot computer. reboot phone in recovery if it still works, wipe system data cache dalvik, shutdown. connect to computer press volume up. see download mode. open tool and try again.
if that doesnt work, some other guys reported changing port number somewhere.

Creating a troubleshooting thread to see if might be able to get some help on a big problem I'm having with my LG G2...
I'm trying to restore my VZ LG G2 to stock so that it can be returned (audio input is malfunctioning). I am currently running TWRP + CM 11 Nightlies on it.
When I enter download mode, I see the screen "Firmware Update" and it says "B99" and "Rooted" at the bottom.
When I use the R&D Test Tool + LGMobile Support Tool to try to restore to VS98011A_01.kdz, the software update runs on my computer as if it is pushing the update to the phone, but the phone itself shows no actual status change. It just sits there with 0% on the status bar.
When it finishes on my computer it says (on my computer) that the software update was successful. Unfortunately my phone boots into CM just like it normally does with all my apps and data there.
Based on some suggestions I have seen, I have tried manually changing to COM 41 and disabling the device as a modem in device manager -- does not make a difference.
I have no idea why no actual change is happening on the phone. Any suggestions?
Man, this is brutal. I thought that maybe the issue was that I was using the 3.10 LG United drivers instead of the 3.8 drivers, so I uninstalled 3.10 and installed 3.8.
Unfortunately now the LG G2 is recognized when it is in normal mode (running CM 11.0) but Windows shows "No drivers found" when I put it in download mode:
USB Composite Device: Ready to Use
CDC Serial: No drive found
CDC ECM: No driver found
LGE Android Phone: No driver found
Network Controller: No driver found
The last four all show up under "Other devices" in device manager with an exclamation.
Previously I was at least able to see the LG Android VZW etc. etc. under COM/Ports with 3.10 drivers installed.
I am burning so much time trying to figure this out. Mayday, mayday!
For anyone that may come across this thread in the future, I want to share what ultimately worked.
I followed the TOT method instructions in this thread: http://forum.xda-developers.com/showthread.php?t=2448960
It was just as easy as the KDZ method, but actually worked! Here are the two things that seemed to make a difference:
1. I installed the _Verizon_ LG drivers referenced in that thread
2. I manually changed to COM41
Following all instructions in that thread everything worked like a charm.

Hey there guys!!!
Can you please help me with this?
Yesterday i tried to install a new ROM on my LG Android phone (My LG phone is not working properly, it has a reboot loop). I tried to do a factory reset without success -> the dead Android logo appeared :/
I put my phone in Download Mode and connected to the pc but Windows does not recognize my phone.. it says: "USB device not recognized.. the last USB device you connected to this computer malfunctioned and Windows does not recognize it"
I do not know what to do now.. when i try to flash a ROM with the LG Flash Tool it fails because LG program does not recognize my device..
PS: LG Support Tool recognizes my phone (it shows the model) but i cannot flash a ROM
Thanks!!:fingers-crossed:
