Hi. My Nexus 5 is stuck at the flying dots after Lollipop OTA update. Already try factory reset. Can´t connect to my Lap (running Windows 10) because it says in the device manager: Unknown USB Device (Device Descriptor Request Failed), so I can´t manually update the driver and can´t access it with ADB and Fastboot tool. The device has no USB debugging enabled. In the old computer where I used to connect the device and has the drivers installed says the same thing in device manager as my new laptop. Please help.
So you can't boot into fastboot using the button combination?
Hi. Thanks for your reply. I can boot into fastboot with the buttons. I entered in recovery mode and do a factory reset but still stuck at flying dots.
Is the bootloader unlocked?

No, is locked
Here'';s a test: boot into fastboot and unlock the bootloader, reboot the phone into fastboot and see if the bootloader remains unlocked. If it remains unlocked, try flashing a stock ROM since you already did the factory reset.

Is there a way to unlock the bootloader without using a PC?
Not sure as I gave always used a pc to unlock the bootloader.
Was the bootloader unlocked before and it happen to relock itself?

No, always locked. I only installed OTA updates.
OTA updates will always work with an unlocked bootloader as long as the phone is running a stock recovery and is not rooted.
I asked about the unlocked bootloader because a bootloader that relocks itself after being unlocked in a good indication that the motherboard's emmc is defective and the motherboard needs to be replaced.

I never rooted or do anything to the phone, just OTA. Is dead anyway. Can´t do anything to fix it.
You don't have access to a computer to unlock the bootloader? I ask because an unlocked bootloader is required to flash a stock ROM.

I do but can´t do it. Is not detected in my laptop, my laptop send my an error that says that is not working properly and if I go to device manager it says: Unknown USB Device, and can´t update the driver. So is not detected in the minimal ADB tool and can´t unlock the bootloader.
Maybe try another computer, USB cable, USB port, or OS? Could the USB port be damaged?

Turns out the micro USB port was damaged and that´s why any computer was able to recognize the Nexus. It was replaced. Now I fixed the persist partition problem and booting for the first time in Marshmallow . Thank you so much for your replies. Take care
Glad you got the phone working. We're all here to help.
My SM-J701F won't connect to PC through USB, but I can unlock its bootloader from Dev Options in the phone's Settings menu.
Is there a way to flash it without a PC? (The phone's Knox counter is blown, but it is NOT rooted)
I only have mac computer and tried unlocking my bootloader with the xiaomimitool MiTool V2 and am getting an error stating that Procedure failed missing service token. Is that due to running it on a mac? Is there any know methods on how to unlock the bootloader and root on a mac? Thanks!
