reset, reflash ton of roms, not efficient
I think driver doesnt play a role in this, with a non driver install PC I still can mount sdcard as removable disk drive with other phone
maybe a hardware problem?

One thing you can do is that when you plug your phone ... delete all all the devices with "Q" on it in your computer device manager.
then unplug and try plugging back.
sometime happens when window install other drivers for one device it stay stuck with it until you manually delete those drivers. Maybe thats the case. Your friends device id is configured with right drivers. You can also switch to another computer and install drivers there and check.

I have to confirm once more that this problem is not driver problems because it's not necessary driver when mount sdcard (test with other lu6200, other android model with non-driver PC)
I think my problem is hardware error or some wrong IMG is flashed in one strange partition (not system.img or baseband.img etc...) during my massing times of flash new rom

Phone [Q] my laptop doesn't recognize my phone (flash mode & fastboot mode)
Try this:
(1) Go to device manager
(2) Plug phone in and look for any changes in your list of devices (maybe under other devices) should have a yellow box with exclamation mark
(3) Once found right click then click browse my computer for driver software (point to the folder where drivers are)
(4) Install from there make sure driver signature is off like instructions above :good:

Use this ( View attachment driver_androidusb.zip )... It will work for Arc S and Other

A request for the USB BOS descriptor failed.

try to uninstall any Android Emulator programs you have

Check also if both ends of the usb cable are properly connected and intact to phone and laptop.

Install Android SDK, open it, install all drivers with it. That should do the thing, if I remember correctly.

how do you install the drivers using android sdk?

If it's possible for you and not too painstaking, try and format your system, and then do a fresh install. Worked for me when I had a similar problem in the past.

[Q] Samsung Galaxy Nexus I9250 GSM, no Android OS and no PC can recognize the device

Hello all!
I have a major, major, problem. Last night I wanted to flash a new ROM, so I had everything wiped from my sdcard so it will be like new again. Sadly, I was retarded enough to also do a wipe on /system. Now there is no Android OS loaded on my phone anymore and no ROMs on my internal sdcard to flash it.
The phone would boot up and will be stuck on the screen with the white Google logo and the white unlocked lock.
I am still able to boot into Download mode, Fastboot mode and CWM. The bootloader is also unlocked.
The problem is that none of my PCs and Laptops would recognize my phone, not even trying numerous tutorials and reading different similar threads.

Also Odin and GNEX Toolkit doesn't see that my device is plugged in, both in Fastboot mode and Download mode, so I cannot flash with that either.
I hope someone had experienced the same problem or knows a solution to my problem.
Thanks in advance!

you have a driver problem. you need to uninstall your drivers and reinstall them.

So normally my PC would detect my phone even without it having any data or OS on it?
Could you maybe point out for me what kind of drivers I actually need? I have tried so many I got really confused.

Focus on getting the correct fastboot drivers installed, and try to get your computer to recognize the phone when you type "fastboot devices" while connected via USB.
Flash a stock image from Google in fastboot mode. Boot into it at least once in order to regenerate the internal storage partition, before futzing around with custom recovery, root and new ROMS etc. If you flash CWM/TWRP without first booting once into the OS, you may be unable to write files to internal storage hence blocking any further progress.

I have tried almost everything to get the drivers installed on all the PCs I have at home, non of them is regocnizing my device.
tried it on both Windows 7 64Bit and Windows XP 32Bit.
Is my warrenty void if the bootloader is unlocked?

You're holding it wrong. Either that or your USB port/USB cable has died.
