I have bricked chm-u01, now it has no access to recovery or bootloader.
only the access is a chines driver when I connect it to PC that when I searched to identify the driver I found driver English name "HUAWEI USB COM 1.0 (COM4)"
anyone have experience in fixing that, please?

Yes I have it unlocked
unfortunately, I have no access to fastboot or bootloader just a black screen
it happened when the phone failed too many times in the updating step while the bootloader is unlocked
I think you are on just a soft brick you can easily fix that with going to fastboot and flashing the IMGs of our rom

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.
Guys I have been using Nexus 5 since the day it was released. This evening I was factory resetting my Nexus 5 after it rebooted it just got stuck on Erasing. I'm unable to go in recovery mode also as after booting into bootloader mode and selecting recovery it just shows andriod logo and erasing, it's more than and hour like this. Can anyone please help me out with it ?
Edit: The thing is USB debugging is not activated on my device and now fastboot is not recognising my Nexus 5 on my new laptop I think it might be because of either USB Debugg or Driver problems. Ay help would be appreciated.
Can you get into fastboot and unlock the bootloader? If the bootloader remains unlocked after a reboot, you could flash a stock rom. Unlocking the bootloader will wipe the phone.
To be clear, USB debugging has nothing to do with fastboot. It is a driver or cable issue if your computer is not recognizing it. Fix the drivers and try what audit13 said.

hello, I have tried to unlock bootloader through fastboot, but I don't have permission. I found sp flash tool which can flash rom, but I wasn't able load stock rom scatter, so I downloaded some system backup of same phone, I flashed it, now my phone doesn't show anything on screen, I can still connect it through download mode and when i just connect usb to pc it keeps restarting(pc makes connecting and disconnecting sounds).I read that it is because I of bad rom, so if someone has stock rom which can be loaded in sp flash tool I would be thankfull if he could give me the link.
Sorry for my bad english.

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.
