So my nexus 5 was running android 6.0.1 July security update, and I flashed 4.4.4 factory image yesterday so that I can maybe root it more easily. However, after I flashed the ROM it got stuck on "four dots animation", so I left it for an overnight booting. It didn't boot up. I also cant access bootloader because when I press the Volume Up+Volume Down+Power button combination it just restarts the "four dots animation". My Nexus 5 now isn't recognized by my windows so i don't know what to do. If anyone has any idea please comment your suggestion.
Tnx in advance.

keep holding just Power+Volume Down, should work. If not, let it fully drain the battery, then plug it into wall charger for like 30 min, and unplug it. Only then press and hold Volumedown and power
Hopefully this is just a software issue because I had something similar to this before where it would bootloop at the Google logo and it turned out that I needs to get my power button replaced. Since yours has got past the Google logo tho and on to the animation, I'd imagine its just software and you should be able to fix it.
If you plug it into your PC while its off and it starts charging, you may be able to boot through to fastboot from there using the ADB & Fastboot Utility's on your computer, boot into recovery mode and swap the rom.
Best of luck!
If your phone is stuck at bootloop. Easy fix is to mount system/cache again. See the following guidefor whole procedure.
https://itechify.com/2016/04/01/fix-failed-mount-cache-invalid-argument/
Hard fix is to flash the ROM again.
I had the same issue, first method worked out for me.
Best of luck.
After unlocking the bootloader, does it re-lock when the phone is rebooted into fastboot? When unlocking the bootloader, does it only take a few seconds for the phone to wipe the data paritions? If the answer is yes to either question, the emmc chip is damaged and the motherboard needs to be replaced.
Try flashing the older stock Google ROM image you can find and flash the userdata.img file last. Immediately after flashing userdata, use the physical buttons to boot into recovery and factory reset. If the factory reset can't mount or wipe the partitions, it's probably a hardware issue.

The power button on my N5 started acting up, like if i even press it once it will show me the power off option. After that it started to randomly reboot. Now its reboots every 2 sec showing the google logo. When it try to put it in recovery mode, it again reboots. Randomly like 20 in 1 trys it stops in the recovery mode.
1. I tried to factory data reset. I got an error msg something like " Cant mount cache ".
2. Called both Lg and goole for a replacement, but my warranty got over.
3. I unlocked the bootloader using fastboot and tried to flash stock rom, but after the first reboot bootloader command the bootloader again comes to locked status. Still after all process the phone reboots and gets to the booting animation, but it does not move past that( even after an hour).
Device was in full stock condition when this happened. Someone please help me out!!

You should ask questions in the Q&A forum. However i think that it cant be a software problem at all, its the power button, you shold take it to repairs and replace it.

Yeah, definitely sounds like a hardware power button issue. You can still contact LG to repair it for a fee even though the warranty is expired. If you don't want to do that, you (or a tech-savvy friend) can try tearing it apart to see if it's stuck or if there's residue or something like that. This article also has some suggestions, but I don't think they'll be very useful as your power button appears to be stuck down.
I have two Nexus 5 (one is mine, one is my wife's) that have recently following OTA updates from Google stopped booting.
They get to the Google logo, then to the animation and at this point switch off and reboot ad nauseum.
What can I do to bring them back to life?
Never known a phone so prone to firmware issues as this phone!
If the bootloader is unlocked, you re-can flash a stock ROM. Just be aware of the fact that unlocking the bootloader will factory reset the phone which results in complete data loss.
Its locked currently.
Is there a way of unlocking the bootloader whilst in this state?

Try holding the power and volume down button together, you should see it boot into fastboot mode, you can press the volume down button till u see recovery highlighted, press the power button and boot into it. From there just try to factory reset and see if that works, if it doesn't then I'll help you unlock your bootloader with the best knowledge I can offer if u got a PC.
Try booting into fastboot mode and leave it here for about 5 minutes. If it reboots by itself, it could be a defective/faulty power button.
Flash a factory image and it will be fine. i had same problem already, just google nexus factory images all instructions are there as well as factory images.
Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!
Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.

My bootloader is unlocked but phone not detected on pc only black screen nothing else.... Red light flashes whenever connect to charger
Hey everyone, I hope this is the right place to ask for help. Something very weird happened yesterday. After removing my 2-year old Y2 from charging, I started using it normally. After a few minutes, it lagged somewhat and then stopped responding. Without thinking much, I pressed and held the power button to restart it like I have done many times before. But this time, it got stuck on the Mi logo. It kept getting stuck on the Mi logo (after switching off for about a second) no matter how many times I held the power button to restart again. I left it on the logo overnight and it stayed that way.
What I have tried yet:
1. As I said, I tried to restart it multiple times by holding the power button to no positive effect.
2. I tried to boot it up into recovery mode by holding Volume up and power button. That restarts the phone back to the Mi logo and it is stuck again. The "Main Menu" (which I think is the recovery mode) with options like Reboot, Wipe data, etc doesn't appear.
3. I tried to boot it into fastboot mode by holding Volume down and power button. It boots up to the fastboot logo so I guess it is working.
4. I followed the steps in this video. The phone stays in fastboot and nothing happens.
5. I let the phone discharge completely once, and tried charging and booting again. This also did not make any difference.
I could not find any information about something like this anywhere. Since it happened on its own, maybe it is a hardware problem? I did not install anything new in the past few days, not even a new app. Maybe it has got something to do with the battery or some other part?
I'd really appreciate any type of help in how to fix this, in particular the following issues:
1. Is there any way to know if it is a software or hardware problem without complicated tampering with the hardware?
2. Can I do anything to recover the data? I'd be really upset if I lost it all.
3. What all steps can I take to fix it if it is a software problem, preferably without losing the data?
4. If it is likely a hardware problem or a difficult to solve software problem, how I can I encrypt (or even wipe) the data before giving it to someone for repairs? (since I'm not able to boot into recovery mode)
Some extra information if you need it: my phone is not rooted, bootloader is locked, OS is Miui 11 (Miui 12 is also available for it but I haven't installed it yet. Maybe there's a way to install it externally which would boot up my phone?)
Thank you for your help! I'd really appreciate it
Same problem with me please suggest some best sort of solution

Hi, I recommend you first of all back up your data if still possible.
Then, reboot into fastboot.
-fastboot erase system
-fastboot erase cache
- fastboot erase userdata
-fastboot erase recovery.
Then clean flash a rom.
Ok Guys So I Shouldn't Have Done This But I Used Fastboot To Flash Recovery And I think I Did It Wrong. It Said "ok" And Finished And I Rebooted Phone It Resetted And Then Stuck On The Orange State Bootloader Message. I Do The Recovery Mode And Goes Black And Nothing Is Responsive For a While, Sometimes Longer Than Others. This Happens If I Start Phone Normal Or Try Fastboot Or Download.
Because Of My Mistake I Cannot Connect To Pc Software And Im Not Sure Of What I Can Do. I Feel Like Im Not Going To Like The Answer For This But I Got To Take The Blame For This.
Btw i Have A Samsung galaxy Note 20 Ultra Sm-N986u
I think your phone is hard bricked
so you can't get fastboot using volume up+power or via adb?
rescue from manufacturer site pos or just device not being recognised?
It isn't hard bricked it's just way of Samsung trying to make life of simple people more difficult, people who paid for Samsung phones lots of money.
To sort that screen issues what you can surely do is,
Simply press volup + voldown buttons at the same time, no matter if you're on that orange screen or whatever just press those those two buttons at the same time and keep pressing them while you connect your phone to pc. you will boot into download mode. Then flash stock firmware for your phone. After stock of flashed Reboot and start your phone, go to developer options see if oem unlock option is there if it is then oem unlock it if it is not then go back to settings manually change date to year ago, then go to updates disable auto update, connect to WiFi, and press on update several times untill window shows up saying no updates, then go to developer options you should see oem unlock, unlock it.
Then boot into download mode and make sure you have working copy of recovery.
And make sure you follow instructions of whoever recovery you installed on how to boot into recovery. I have S20 plus and too had troubles with it, and the only working recovery for my phone is twrp customised. To boot into it after flashing recovery from odin auto reboot disabled I pressed voldown and power, USB cable connected, then after screen goes off I changed from voldown to volup while kept pressing power button and cable connected. Orange screen with warning showed up for 5 sec I kept pressing and it bottled to twrp and then I was able to install custom rom beyond rom and while installing in aroma I was able ti choose option to remove orange screen.
That's it.
I ran into the same error. I mistakenly loaded twrp's recovery into userdata instead of ap section. The phone was stuck at the orange screen and nothing was happening whatever i pressed. I waited till the battery to dry out and with 0% battery, i directly connected to pc and was able to get into download mode. Then i flashed stock and everything is now back to normal.
