Does your phone boot normally? Can you turn on USB debugging?

yes it boot normally and i can turn USB Debugging and it still doesn't recognize with and without USB debugging mode.

When you select recovery from fastboot, that's when you get the "no command" error?

I do same kind of prob with my PC. The root of problem is mostly the USB cable itself. I've got the stock nXs⁴ cable yet after a year its out I think. When that happens try some many cable.
The prob might even occur due to MTP. If debugging is enable then ADB would recognize nXs⁴ as offline and no Portable media device would be visible in My PC. In that case try restarting PC!

[Q] PC died when upgrading GT540

Like topic says. Was doin' it via LG PC Suite. Now it's only LG logo on my phone. Any ideas what should I do?
Are you planning to install custom ROMs on your phone?
If so, check this out:
http://forum.xda-developers.com/showpost.php?p=16783348&postcount=1
Instead of doing this:
Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and let Windows install any drivers it needs.

Do this instead:
Hold down volume down and plug in the USB cable and 'download mode' should come up on the screen. Let windows install any drivers it needs. Then launch software update.

Hope it fixes your problem and device
Same thing happened to me, bricked my device, took it to phone shop they flashed the board and it worked again, think i could have just entered download mode and reinstalled but, i was a noob then still am tbh
Just put your phone into download mode.
Flash fastboot.
Then reflash your ROM!!
ALL DONE XD
Any
You can flash any ROM you want via fastboot and any failed attempts won't completely brick your phone.

Unable to flash anything with fastboot

Hello.
I recently installed the 4.3 ota update. I knew I would have to reroot. After the update I have tried everything I can think of to flash a new recovery or bootloader or anything. All without success. Fastboot simply says "Sending...", the phone says "downloading..." and that's the end of it. They would both sit in that state forever if I let them.
I know I'm not alone on this issue. I have searched and searched without finding a solution. Does anyone know of one?
Thanks.

1. Usb debugging enabled and bootloader unlocked?
2. Correct drivers installed, try these usb naked drivers for instance https://www.google.nl/url?sa=t&rct=...=RUlfH35SAJki_DdLfo8MeA&bvm=bv.51773540,d.Yms.
3. Used the original usb cable or tried another usb port?
4. If you type fastboot devices in fastboot mode do you see a serialnumber? The same for adb devices in adb mode?

USB debugging is enabled.
I've tried the original USB cable and others. I've tried different USB ports.
adb works fine. Fastboot recognizes my phone and prints a serial number. Fastboot even works for locking/unlocking the boot loader.
There are no "drivers" in the Linux world. Should I find someone who has a Windows system and ask to use their computer?
Thanks.

So. I solved the problem. I now feel like an idiot.
I plugged my phone into a Windows system and a nice notice popped up saying that my device could run faster if it was plugged into a USB 2.0 port. Then it dawned on me that only a few of the ports on my computer are 2.0 and that I had tried one of them previously but with an extension cable (because it's in the back and hard to reach). I unplugged the extension cable and plugged the USB cable directly into the port and all was well.
I hope that others who have had this issue find this useful.
Thank you for your help.

Reformat computer or try different computer
Assuming, you have no problem with your USB port, USB cable, installed latest LG USB Driver 4.0.4, running Windows 7 or 10...
We need more detailed info from your part to tackle this problem. Are you running on stock rom, kitkat or lollipop? Are your rooted and do you have TWRP recovery?
Then, you need to disable "USB debugging" from the "Developer options" menu. Then replug your USB cable and you can now select MTP instead of charging only mode. Good luck.

i have fought the no mtp problem and everytime i lost. if you try new things they just dont work. what has worked was to reformat computer then it will work..
I had the same problem with my G2. Unknown usb device, and the error was: "unable to get device descriptor" or something similar. Tried all software solution without success, so i have started to looking for hardware defect. I've changed the usb module, but no success. So, as a last chance, tried another mainboard. And "tadaaaa"... That was the problem. So, start to look for a working g2 with cracked screen, as i did.

Oneplus 2 no OS installed

Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.
Try this

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.
I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Any other ideas, because I do not own any other USB type C cables. The one I'm using is the one that came with the phone, but I have never had any issues with it.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.
you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?
I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.
