PC doesn't recognize my phone (cannot install ROM) - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

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:

[Q] Lg F320S Stuck on bootloop

Hi all,
My phone is bricked with following syptoms:
1) Not being recognised in download mode
2) Adb without root acess (unable to push files)
3) No recovery
Detailed problems
I have a (Korean) Lg G2 (F320s) and its stuck on bootloop. It goes into download mode with Vol + with plugging into computer but the computer doesnt recognise it as attached...no sound, nothing in device manager and no found by Lg Flashtools or Kdz updater.
When simply turning on i connect it to the PC it shows as an ADB interface device and i have ADB but no root authorization (my phone was rooted before).
Lastly when i try to enter recovery it just flashes a couple of times and goes black...back light still on. In this mode when i connect it to PC it shows up several drives and phone comes up as Qhsusb_bulk device. I read a thread using UBUNTU to repair this but it wont work for me....the PC just hangs up and Ubuntu is unable to mount the drives (Even after the settings from Dconf Editor).
Please help i have been stuck for days

Please help ppl... is there a possible solution to the problem..?? JTAG maybe??

[Q] Gionee E7 (32GB) got bricked

I tried to downgrade from Kitkat to JB via flashtool this morning which I often successfully flashed with the same method. But while the flashing is going on and almost finish the flashing (system.img, userdata.img, etc. are already flashed), there seems to be some problem and popped out that the flashing is fail. And then the device does not boot up. While I tried to reconnect the device to PC, the PC cannot recognize the device as shown in the picture. Unable to process any further method. Does anyone in this forum knows how to recover the bricked device like this?
The phone starts? In a black screen?
If the PC detects it like that the phone has some energy and connection...
Does anything apears on the screen? Can you go to the Recovery Mod?
Have you tried to force the driver installation on that USB item that appears on device manager?
Do you have access via ADB or fastboot?
Did you nottest in what partition did the error message appeared?
Please provide some answers to these questions so i can try to help you...

Nothing on the screen. Not able to boot into recovery or adb is not working. The phone is just death. But, when I insert the usb cable, the pc can detect it. I even approach the Customer Care here in Aizawl, but they cannot fixed. Even when I followed the instruction as per one xda member posted here, The qualcom hs - 9006/8 is displayed on the device manager and when I tried to flashed it with emergency mode, the result always the same. FAILS

Try this:
- Start GNQC with the phone disconnected
- Connect the Phone and see GNQC recognizes the QLoader
- If so, press power button until the phone vibrates
- Wait for the GNQC recognizes again the QLoader and press Download on Emergency Mode
Use this KIKAT ROM: https://docs.google.com/uc?id=0B8H5JoBDpTnJMGE2QTJPR0FWX0E
This worked for me, i had the phone completly died, not even recognized by the PC, waited a day and tried again.
Once the QLoader is recognized your good to go!!
I'm having another problem after that, now theres no GSM/3G signals....
I need a EFS backup with the TWRP recovery.... No one seems to have

I have the same problem, screen is completely black after trying to instal newer official rom. When I connect it to PC, it detects "hid device". I tried power + volume buttons combinations, but nothing changes. Sometimes notification led turn red for a few seconds but nothing else. And once win xp randomly detected phone as that "q..." thing, but it doesn't anymore. What else can I do?
Can anyone help me? I tried everything and my phone is still hardbricked.
Hello guys
Today i received my E7 and i tried to update via the tool unfortunately something went wrong and now i cant open it nor fastboot or recovery. Some hours ago i tried to connect via usb and appeared on the GNQC but later it showed as unknow device. It was my first day with the phone. Right when i connect /disconnect the usb i can hear the sound but i cant do anything. Is it dead or i can revive it somehow?
It was the first day:crying::crying:
Reinstall the drivesbob the PC, press 30 secs on the power button than connect the phone to the PC. If appears a QLoader port use emergency download on gnqc 1.6.9.0
