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.
so i unlocked, rooted and installed LOS on one of my classmates honor 8 a few months ago. for whatever reason he decided he wanted to go back to stock and asked me help. due to work and school i was unable to help so he came on to xda to find help.
he ended up using a guide and............... well, its all f*cked!! i dont know how but his phone is not only bootloader locked but also FRP locked.
to make things worse, the phone wont boot and it has no recovery. i have tried the vol+ and power, vol+- and power but non work. i am able to get into fastboot. i have thought of maybe sending the phone in to maybe huawei us but the phone came from ebay.
the phone was a damaged ebay win that was repaired by me. it worked great but i dont know if its possible to send to huawei for repair. anyway, i would appreciate any and all help.
You might need to reset with the /sdcard/ dload method. Check out the other forums for instructions.

It's highly unlikely that you're SOL, if you can get into the bootloader then you can flash the stock recovery. If you can flash the stock recovery, you can flash a rollback package to completely restore everything to stock.
So long as you have a working fastboot, you're fine.

ah, the thing is..... both the bootloader and FRP are locked. as i mentioned, he wanted to return to stock and followed a guide here. he doesnt remember what exactly he did as it was almost a month ago but it ended relocking the bootloader and FRP. i really feel horrible for not helping him which is why im desperate to get this working. i might just end up giving him mine.

so i tried and nothing, i get to the blue splash screen and the phone just reboots. i keep trying to unlock the bootloader but i get the same error as i posted above. shouldnt i be able to unlock the bootloader? im thinking that i have some kind of driver problem.
my pc is pretty much dead so im using my laptop and im not sure i have it set up correctly. anyway, i know oem unlock is required to unlock bootloader but is there anyway i can unlock straight from fastboot?
Try a 'fastboot oem relock' with the unlock code, then after the reboot, try unlocking again.

Hello guys, I dont know whats happening with my Nexus 5 right now. Its stuck on Google logo which appears during restarting of the phone.
I have tried everything. I try to go into recovery it dosent work. I tried changing it to CWM from TWRP still it stays TWRP i get errors while flashing .bat files like (error: failure to write). Please help been stuck on this since past 72hours. Any help to resolve this issue is appreciated. Thanks :crying::crying::crying:
If the bootloader is unlocked, relock the bootloader and reboot into fastboot mode. If the bootloader unlocks itself, the internal memory is probably damaged. If the bootloader remains locked, unlock it and flash 4.4 using fastboot commands.

OEM can be locked and unlocked. But the only problem now is i cannot override the previous partitions as there is an error "failed to write" i dont understand why is this happening this is also the reason i cannot get into my recovery as when i enter recovery it gets stuck for some reason.

Let's start with the bootloader.
Boot into fastboot mode, lock the bootloader, reboot into fastboot mode. Does the bootloader stay "locked" or does it go back to say "unlocked"?

I tried the 1st step by overwriting twrp with cwm dint work. Also ADB isnt connected. I tried to but just fastboot works.
I recommend flashing stock 4.4 using fastboot commands.

I tried flashing new roms it says failure to write to cache,boot,recovery everything fails!
There is no way to erase partitions as it fails!
I would say the internal memory is damaged and will require a motherboard change.
I kept my phone on charge for a few mins and when I came back to unplug, it was stuck on google screen. tried turning off the device or restarting it but nothing works. The phone was extremely hot. My phone is completely factory stock. the bootloader is locked too. how to recover it now ? please help.
i tried entering recovery mode but as soon as i select recovery it gets back to google logo screen again.
right now i have kept the phone in freezer now.
my bootloader is locked .. can i still unlock it and flash factory image ?
help ?
not a single reply ? bump...
Are you able to communicate with the device using fastboot?
Try flashing the stock images via fastboot
You won't need an unlocked bootloader for this

whatever command i use it says OEM unlock is not allowed.
Just throwing out ideas that you may have already tried. If I understand right you cannot get into recovery which eliminates trying to sideload the stock image. Your bootloader is locked and it will not let you unlock so booting into TWRP is out of the question. Are you just wanting your phone operational again? Have you tried wiping/factory resetting with fastboot commands? i.e. fastboot erase userdata or fastboot format userdata.

both command not working .. same bootloader locked message.
error message " Please unlock the device to activate this command"
anyone else can help ?
I would contact Google customer support. Even though my phone was out of warranty and I was not the original buyer (bought in eBay), they were willing to make a one-time exception for an RMA. I didn't use it because my phone is rooted and I was afraid of being charged for any repairs. As long as your phone is stock and unrooted, you have a chance. Just say that you think you have a hardware failure and while you understand that they are in no obligation to help, you would appreciate anything they can do.

Hello! Faced such a problem, yesterday I installed the Octavios firmware. Decided to block the bootloader. As a result, the bootloader was blocked and the system flew. When flashing via fastboot, it gives an error that the bootloader is locked (how can I get the phone out of this position? Thank you in advance!

Oh boy, you should NEVER lock bootloader unless you are going back to STOCK ROM...
Never been in such position but have you tried to unlock bootloader again with Mi Unlock tool?
Yes, I tried. 99 percent hangs for about a minute, then an error

You must have screwed it honestly... There is something like EDL flash but I have zero experience in that and its not that straightforward. Look at YouTube. Otherwise I have no solution other than Mi Service

You unlocked the bootloader before? Then use the unlock tool in fastboot mode or other option edl
