Nexus suddenly would not turn on, and now the bootloader hangs when factory resetting - Nexus 5 Q&A, Help & Troubleshooting

So today I woke up and my phone was stuck at the Google logo and would not boot up after having no problems ever. I tried to factory reset the phone using the hammerhead build on Google's website, but it gets stuck at "erasing 'cache'" and my phone hangs at the bootloader when it gets to this point.
I've also tried installing CWM and wiping from there - cache erases fine but erasing data gets errors such as "Error mounting /data."
I don't really know where to go from here so any help?

Figured it out
Ok, never mind, I figured it out. I flashed a Kit-Kat bootloader to solve the freezing problem and manually flashed all the factory files line by line. Booting up well now.

[Q] Help

So out of nowhere my Incredible started rebooting on a loop. I have the MIUI installed on it and has always worked fine, but now it won't boot.
I plugged the phone into my comp and it won't show up in "my computer" either.
What do you advise I do?
I went to bootloader and tried factory reset on the phone and that won't work either...just keeps looping the boot screen.
anyone know?
So you can still get to the factory reset? After doing this, does it remain in the recovery screen long enough to reflash? Try using your old NANDroid backup and reflashing. Hopefully this will work.

verizon kyocera brigadier keeps rebooting

I have stock rom on my phone but after a standard update the phone restarted and is now stuck in a boot loop. I have factory restored the phone and cleared cache with recovery tool on phone but still stuck please help.
It's software related. I have managed to fix this issue with battery pull. But you will have to re sealed the phone again.

I am stuck on verizon screen after doing nothing

It seems my phone started saying that random general apps were crashing and then i tried to reboot thinking this would solve the problem now my phone wont boot past the verizon screen. Am i really going to have to flash stock to repair this? or is there another way?
Nevermind I wiped and reset to factory then rebooted to safe mode and now it works, but I've lost root and all my files/apps.

[Q] XT1033 black screen issue

Hi there, my mother have an XT1033 and some days ago the phone got bricked in a black screen. I don't know what she was doing when it happened, but i know that the phone have its storage almost full, maybe this is the cause.
But the problem is that i tried to do a hard reset, but got an "Boot up fail!" trying to access the Recovery.
So i tried to unlock the bootloader, aparently it was succesfull since i could access the Recovery. But the wipe data/cache option solved nothing and aparently no data was wiped.
I tried to flash a new recovery, got the "OKAY" output but the recovery stills the same. Tried to flash a stock rom and still nothing changed. And actually, for some reason the phone did a successfull boot after all this, and was still with the old system, with the same data as before, and spamming error messages on the screen untill going to the black screen again.
I tried almosst everything, someone have some tips?
And sorry, english is not my first language.

Wokeup to my phone stuck in a bootloop... [SOLVED]

UPDATE: I have finally managed to get my phone working again! Am now currently re-downloading all my apps and transferring all my files back to my phone, running AOSPExtended (https://forum.xda-developers.com/oneplus-one/development/rom-aospextended-rom-t3732194) with OpenGApps. I'll write the steps I took to figure this mess out at the end of this post for anyone who might encounter the same problem in the future. :good:
So last night I left my phone charging overnight from 54% as I was downloading a couple of files (my internet is 1Mbps or 125KB/s). I've done this a couple of times before with no problems what so ever. But this morning I woke up and my phone was in a boot loop. I've tried everything I can think of and everything I could find on these forums, but to no luck. I am at my wits end and I have no clue what to do except to do a full factory reset, which I'd rather not do as its been a while since my last backup and I would lose a lot of precious files...
My Phone: OnePlus One 64GB Sandstone Black, purchased in August 2014.
ROM: cm-13.0-ZNH5Y-20161105-STABLE-Sultan-bacon
Recovery: TWRP+3.0.3-2-TugaPower
Firmware: bacon_firmware_update_2016_1-25_.4.0.1.c7-00011
The boot loop itself is odd, I'll describe them separately here.
-I can boot into fastboot, but not while the USB is plugged into my PC. I have to boot into fastboot, followed by plugging it into my PC. If I try to boot into fastboot while it is plugged in, the screen goes completely black and goes back into the bootloop. However, the phone shows up in Device Manager during the black screen.
- I can boot into Recovery, but the phone automatically reboots and goes back into the bootloop after a few minutes. One thing I have noticed is that if I let it reboot by itself, all the settings reset (including the confirmation to allow modifying of files when you first boot into recovery). But if I manually reboot back into recovery, the settings remain the same; atleast until it reboots automatically again.
Here, I'll list the things that I have tried to no avail:
1. Following this post - https://www.reddit.com/r/oneplus/comments/3izejg/so_youve_just_bricked_your_oneplus/, when I try to wipe Dalvik cache and cache from recovery, the phone goes right back into the bootloop
2. I tried flashing a newer version of TWRP (3.2.1-0 and 3.2.1-K2). After flashing I try to boot into recovery but the TWRP loading screen displays, and then goes right back into the bootloop. It wont even let me into the main menu.
3. I tried flashing a ROM through fastboot (via this post, https://forums.oneplus.net/threads/guide-oneplus-one-flashing-fastboot-recovery.301131/). The phone still remains in a bootloop.
HOWEVER, if I flash my previous recovery (TWRP+3.0.3-2-TugaPower replacing the stock cyanogen recovery from this method), my phone manages to get past the 1+ screen, and goes through my custom power on screen, and reaches the "Android is starting... Optimizing app 1 of 67." But it never gets past app 1, freezes, and then reboots. So now it's stuck in this "extended" bootloop thing.
What I want to know: is there anyway to fix my phone, or will I have to lose all my data and do a full factory reset through the ColorOS method? If anyone has any experience with this or knows a way to help, please don't hesitate!
Thank you in advance.
WHAT WORKED FOR ME:
After following the steps in this post (https://forums.oneplus.net/threads/guide-oneplus-one-flashing-fastboot-recovery.301131/) my phone was booting up, but was kicked back into a boot loop after freezing at the "Android is starting.. Optimizing app 1 of 67" screen. However, the recovery was now the default CyanogenMod recovery. I then re-flashed my previous recovery (TWRP+3.0.3-2-TugaPower) from fast boot, and it was now stable (no more auto-reboots). From there I made a backup off all my files onto my PC before proceeding. After that, I did what this post said (https://www.reddit.com/r/oneplus/comments/3izejg/so_youve_just_bricked_your_oneplus/) and wiped Cache + Dalvik cache. This allowed me to boot all the way past the "Android is starting" screen. However, the phone was still rendered unusable as there were non-stop notifications saying various apps had stopped working. I then booted back into recovery, downloaded and pushed a new ROM and GApps package on to my phone, wiped system, data, cache, dalvik cache, and installed the ROM and GApps pacakge, clearing the cache one more time before rebooting. Everything is working beautifully so far and I could not be happier! I hope this helps anyone else who encounters this problem, Cheers!
