I've successfully installed the Open Desire rom on my HTC Desire, but if I try to plug in my phone to my PC I get a windows noise (asif a USB device is connected), but no access to the actual device (e.g. the drive doesnt appear in my computer).
Any ideas on what to do? It was working fine on the same PC before installing a new rom...
Thanks.

Sounds like the usb brick as mentioned above.
What recovery method did you use? Is your phone seeing the sd card?
I had the same problem, can you install from Market? I fixed the problem by changing the default install location for the apps.

Now I can connect both discdrive mode and htc sync. Latest OTA did this for me.
Hi everyone, I bought an LG G3 Korean version (F400S) unlocked recently. It is a good phone but I am experiencing three annoying issues (out of the box) with the phone and they are:
1. NO sound at all from the back loudspeaker. The volume is set to maximum, there is no sound from music, video, notifications, touch sound effects, or even ringtone! Surprisingly, when I connect my earphones, there is sound in my earphone, when I remove the earphone, absolutely NO SOUND from the loudspeaker. The sound from ear speaker (the one used to make call) works. I have tested the ringtone in the Hidden Menu, when the ringtone is being played, there is no sound at all.
2. The LG G3 charges well when connected with the charger and when connected with my laptop as well. However, whenever I connect the LG G3 to my laptop, it only charges, it is NOT RECOGNIZED by my laptop. I have the LG Mobile driver installed (downloaded from the LG website (Korea website)), the LG PC Suite installed, the LG Mobile Phone Support Tool installed. Whatever I do, changes the USB cable/ USB port, try in different windows version (Windows 7, 8.1 and 10), USB debugging on and off, reinstall driver, reinstall driver from the option in LG PC Suite, restart the PC several times, NOTHING happens. It is not recognized at all in my laptop. ALSO I cannot see any thing related to LG driver in the Device Manager.
3. USB OTG does not work. I have tried with a working OTG cable to connect a pendrive in my LG G3, it is not recognized, even in the File Explorer of the phone. The cable and pendrive is however detected in my other android device.
The Android version of my LG G3 is Android 4.4.2 (I have received only one update for improving Google experience (about 10 MB).
The Kernel version is 3.4.0
The build number is KVT49L.F400S11a
Software version is F400S11a
Please help me, I have googled for the problems, searched in Youtube as well but no solutions. The phone was bought online, it is original but I have no warranty and even if i need to repair, I will have to send it back to China, which will be money and time consuming. Please help me.
Upgrade to v20F using this KDZ and let me know if it resolves your issues or not

Thanks for the reply, I tried your suggestion, but it did not work. Again, when I tried to connect the LG G3 to the PC so as to flash with the KDZ, it says on the taskbar: 'The last USB device you connected to this computer malfunctioned, and Windows does not recognize it'. In the Device Manager, I get USB Device Not Recognized (Error Code 43), Unknown USB device (Device Descriptor Request Failed) Error Code 43. I googled this issue as well no success, I reinstalled the LG Drivers, rebooted my PC, again NO LG DRIVERS in the Device Manager, and whenever I connect the LG G3 I get the same message I mentioned above. Hence, I cannot upgrade to the v20F version as I cannot connect the device to my PC.
UPDATE: I cannot put the device in download mode for flashing. I hold the volume up button while connecting the cable to the USB 2.0 port. The LG logo appears on the phone and it just charges. Also, I have tried to remove everything related to the drivers and reinstall, now I do not have the Error Code 43, BUT still the phone is not recognized.

Pull the battery
Only press the volume up button while connecting the cable to the USB port.
Let me know if that works. It sounds like your pressing the power button first, pressing volume up and then plugging the usb cable in
If it doesnt theres also the adb method as well that i can tell you after

I tried it but I only get a picture of a battery with a USB cable connected and a yellow triangle with an question mark. No download mode, and it is not detected by my PC. Please give me further suggestions. I am continuously searching how to solve these issues.

First update your drivers on your computer. If that won't work try different ports. USB 2.0 or 3.0 can make a huge difference. Your speaker is probably dead. And i don't have any experience with USB OTG so I can't help you with that

Already tried that with the '15-sec ADB' something like that + with Android studio, I have searched on youtube and google how to do it, but nothing happen when I enter the command, it just says that device not found. Whenever I connect a pendrive or my other phones to my PC, I can see in device manager, it refreshes and the driver for that particular device appears. BUT there is NO refresh nor any driver appearing when connecting the LG G3. Today I tried it with my friend's USB cable (he has the LG G3 (D855), it does not detect as well in his PC but his phone is detected in his PC. I really do not know what is the matter :crying:

Thank you for your reply, I have already tried all of these, nothing is working.
Did you figure out how to get your phone recognized by the computer? I am facing the very same issue and I'm feeling hopeless

No, i am still having the same issue. I think with an update it will be okay (but I have not received any update till now! I am stuck with Kitkat 4.4.2). If it is a hardware problem I will have to return it or replace the USB port or motherboard.

Oh, OK thanks. I'm still reading forums in search for a definite solution.
Good luck!
Hello my friend
I cant understand the D855 while trying to connent it to my PC.
I have installed all the drivers and PC suite
When I connect it with the usb cable- its makes the desired sounds - seems that everything is ok!
even V green mark that the driver installed is shown.
But, the most important- I cant see the Drive shown when I open "my computer" on PC
Dont have access to folders and files.
I tried more then everything
Change to MTP
Debuuging mode
Change some usb cable
I already make a hard reset.
The main problem is with morelocal 2 language.
In order to make the app change a language- I must connect it to the PC.
So
what do you think the problem is ?
Is there any way to install another rom without connection to PC ?
Thank you so much
salman
Well, I have kinda the same problem. My G3 isn`t recognizied by my pc or laptop in any way beside that sound it makes if you connect an usb device to it. It doesn`t shows up in the explorer or the device manager no mater how many times I install the drivers. I also tried to change the mode from MTP to PTP and anything else that is there. I resetted it a few times but nothing. Debugging mode also didn`t change anything. And of course I can`t flash a stock firmware because the Flash Tool won`t recognize my phone. What also is strange on my phone, if I disconnect my phone from my pc, my phone is still "charging" and it doesn`t change until I reboot.
I`m open for any suggestions which could solve this problem.
My G3 is a European modell, with 32GB. Current version is V30C and it was rooted with kingroot for this "two apps on screen" thing.
Hi all.
I have a wonderful LG G7 (model G710EMW from Brazil carrier Claro).
Recently I've tried to connect it to my new car audio system that supports Android Auto and it didn't work as expected. Long story short, I've discovered that USB does not work on my phone.
Charging works alright, but anything that requires an USB connection simply does not work.
When I connect my phone to my PC, the phone starts charging, never shows the "USB connection" notification icon and the PC does not recognize anything. The phone also does not allow me to choose the kind of USB connection that is to be used (you know, MTP and the other options). When connected to PC through USB cable it displays exactly the same behaviour as if it was connected to a regular charger.
I have tried different cables, being two LG original USB-C to USB-A cables, an USB-C to USB-A from Xiaomi and a generic brand USB-C to USB-A charging and data cable. All of them show the same behaviour.
I did soft reset my phone, thinking maybe some app I downloaded could be interfering, but it also did not change anything. Also hard-reset, but no change either.
I've already tried replacing the circuit board with the USB plug but that also didn't change anything.
The only time USB works is in EDL mode, which shows expected behaviour. PC recognizes the "Qualcomm HS-USB QDLoader 9008 (COM3)" port and with QFIL I can navigate through partitions and stuff seems to work.
I would try installing a different ROM, but as I would need to cross-flash to unlock bootloader (default ROM does not enter fastboot) I am stuck on the USB issue now.
Has anyone seen something like this? Any suggestions to what I could try?

I did try on another two different computers, all on Windows 10, and none of them recognized the phone except when the phone was in EDL mode.
I haven't tried installing drivers for the phone, before when it worked I never had to manually install anything for the PC to recognize my phone.
I'll give that a go, thanks!

Just to let you know, I could not find the USB driver for regular usage of the phone connected to the PC. What I found was drivers to use the phone with ADB and drivers for EDL mode.
I got to test the phone on a Linux Manjaro installation and there the computer also did not recognize any new device with "lsusb" command, whereas using a working LG G7 ThinQ the output of "lsusb" was:
Code:
Bus 001 Device 004: ID 1004:61f9 LG Electronics, Inc. Optimus (Various Models) MTP Mode
Note: the working phone had the USB connectivity option set to "Charge only" (or something like that, my phone is in Portuguese).
