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.
Hi,
My phone went into a boot loop.
I can access the fastboot menu but the device is locked, I obviously now cannot enter developer options to unlock it
When means I can't unlock the bootloader, and without unlocking the bootloader I can't reflash the device. Bit of a loop of death
Any suggestions or is it a door wedge?

Hello and welcome to XDA-developers!
You can follow this guide to flash stock firmware through fastboot. If you have any doudts just report!
I was trying to unroot I was on 9.0.4 and had magisk 17.1 and no twrp since i updated from 9.0.3 or whatever update was before. I factory reset and had no more root, and no twrp. I still had a unlocked bootloader so I went to adb and locked it and then it rebooted and gave me the red message "your device is corrupt and will not boot." it doesnt boot at all to anything not even recovery and I am just in fastboot. I tried MSMdownloadtool but it doesnt work. I am in windows test mode and tried but it would not show up on the msmdownloadtool. It doesnt connect. Also in adb it does not show up. Help me!!!!
it says bootloader is locked now in fastboot though i cannot boot in to anything
i just unlocked through fastboot so now im still stuck with just a unlocked bootloader

Msm download should work now as well with your bootloader unlocked

MSM download will work.
Just download appropriate Qualcomm drivers before proceeding.
Use Volume Up while connecting to PC.
MSM should detect the device connected in any of COM ports.
Just go to this thread https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 and follow procedures to recover your phone just like how it is when you bought your device. Also, it will lock your bootloader.
Hello
So I followed instructions for relock the bootloader but I think I made a mistake now I'm in a big big mess :/
I got a message "Your device is corrupt can't boot", thing is I wasn't rooted anymore I flash some file before relock the bootloader.
The thing is I don't have access to the Fastboot anymore no commands working so no EDL.
The only thing I have access is the Start/Restart Bootloader/Restart recovery
So I wanted to know is there a solution of do I need to contact asus and pay for repair.
Thanks in advance
