Infinite boot animation screen Nexus 5 - Android Q&A, Help & Troubleshooting

***
SO I AM RENDERING THIS NEXUS 5 DEAD (BRICKED FOREVER)
***
My daughter was using this Nexus 5 device and the power button started causing her problems.
Well I removed the power button and ordered a new one. So now the power button is not an issue.
But I guess during the time that the phone constantly kept rebooting due to the bad power button, something got corrupt.
Now the device gets to the boot animation and never goes any further.
There are no options in recovery for me to use.
I have working ADB and Fastboot on my PC. I can see the device with Fastboot but not ADB because I can't get the device to boot into the OS for me to enable USB debug.
But I know ADB works because I used it just the other day on a Galaxy S5.
I have tried to run fastboot oem unlock, it unlocks the device then once you reboot the boot loader, it says locked again.
I have tried using Nexus Root Toolkit and hit unlock and it unlocks then says the phone will reset itself and just be patient. It may appear to bootloop but just wait.
I waited for an hour and still just sits at the boot animation.
What are my options without being able to enable USB debug since the device will not boot to the OS?
I am able to Temporarily boot to a custom recovery, but I can't mount data!!!
With Temporary TWRP, I am able to use ADB and I get a success message when I push a new system image to it, and when I push twrp recovery to it, but when the phone reboots, I find out that neither the system image or recovery were actually installed.
I looked into bad partitions, tried some fixes, and nothing works. I am so far beyond frustrated with this thing. I guess I will wait one more day to see if anyone else has any other ideas for me to try, then I am just going to put it in the trash.
- Bootloop
- Bootloader doesn't stay unlocked
- Unable to mount storage
- USB Debugging is not enabled and can't be enabled
- Can't install OS image
- Can't install Recovery
- Can run TWRP temporary
- Can use ADB when TWRP Temporary is running, still can't mount anything

[Q] Stuck in boot loop, exhausted almost all optons

LG Escape running 4.1.2
here is the progression of events:
1. rooted device
2. root seemed successful and no malfunctions
3. backed up all apps and system data with Titanium backup
4. the lg escape has no way to unlock the bootloader, so I tried various other methods. one of which was entering recovery mode via terminal commands. this is basically a hard reset, and it wiped all my data
5. I restored all my apps and data from my external sd card with titanium
My best guess is this is where something went wrong
6. upon restoration it prompted me to reboot the device
7. reboot passes manufacturer logo, but resets when AT$T logo appears
8. as stated earlier, there is no way to enter recovery mode during boot.
9. there is a hard reset during boot, but mine will not work, as it requires touching buttons which do not seem to be active in my stage of the boot sequence
so, I understand this does NOT mean my phone is bricked, but I don't know how else to get it to boot back up, or what is even causing the boot loop, as I DO NOT HAVE ANY CUSTOM ROMS flashed. any help here is very appreciated!
EDIT: so I have attempted to use adb on my pc to reboot into recovery from there, but it occurred to me that while I was in recovery the first time, I never checked "usb debugging". as a result my adb console commands cant even see my device. any way to turn on usb debugging while locked in a boot loop?
also, I can get it to enter download mode. I was hoping I could just reflash the firmware to it without needing to enable usb debugging, but have no clue how to do that while locked out of the phone.
I realize this is a very specialized set of questions, but it is necessary to ask here as the most people will see it. im open to any ideas

i have now tried to flash the firmware while in download mode using a less than legitimately obtained lg R&D tool. however, i need V10F_00.kdz and i am facing a bit of censorship. any kind soul willing to host this file on dropbox or similar so i can download it?
Usually devices have a button combination to press when powering on to get into different modes. Maybe try searching for the button combination of your phone on Google? Try ' lg escape button recovery ' ?

believe me i have. the only combo i can get to is download mode. there is a combo for a hard reset, but my touch buttons arent active during boot.

I Don't Know what to do!

Hello, I'm new here. I have rooted my new fire 7in 5th gen tablet. I used the flashfire beta app to flash a rom which I found out that the rom had bugs, so I decided to install cm12.1 using the same app, but the app glitch when it started installing the rom meaning it didn't finish and kept installing. I decided to power it down and reboot it back up. It showed the cyanogemod logo booting with animation but nothing booted up. It kept booting like a bootloop. I restarted it multiple times and the same errors keep happening. I tried go into recovery mode by holding the volume up + power button at the same time when i was boot it up. it only went to amazon logo and not recovery. I also plugged in the device to the computer using my factory cable to see if I'm able to enter fastboot mode. It worked, but it wouldn't allow me to flash anything. The tablet greeted me a message saying flash not allow, but the commands were able communicate with fast-boot and cant get it into adb because the boot loop. I had actually enter fastboot mode using commands which worked. Sometimes when i type a different command it said failed remote. Some commands actually worked but I don't what other commands to use to fix it. It has been 10 months since this happened to me. I'm not willing to give up on it because their has to be alternative ways of bypassing these issues. Is their any way you guys can tell me how to fix this? Thank you.

Reboot to TWRP Recovery Using Fastbooot Mode

Hi, I was just messing around my phone and installed five Magisk modules and then after reboot, my phone didn't want to turn back on. It was stuck at the boot animation and nothing else was happening. I kept it overnight plugged in to see if it turns on by any change. But on the next day, I found it to be super warm and it was still stuck at the boot animation.
Now all I have to do is, reboot to recovery mode, clear its whole data and reinstall the ROM (as I didn't make any backup).
But the main problem is that the Volume+ button in my phone is broken, and it does not work! Somehow I can still access the fastboot mode. I can use a command to delete all my data. As they're Magisk modules, clearing the data might not unbrick my phone (I'm not sure).
Is there any way I can reboot my phone into TWRP recovery through fastboot mode? Or can clearing the data in fastboot mode fix the problem?

Two Methods.
1- Some phones actually respond to fastboot reboot recovery. This is quite natural given adb reboot recovery, but unfortunately is non-standard. I found lots of people suggesting this method so I offer it here in the hopes that it works for some, but it didn't for me.
2- Some phones will actually let you book into an image via fastboot without flashing it. This will allow you to load a recovery image without needing to reboot the phone at all. You need a copy of the recovery image on your computer, but running fastboot boot image.img should do the trick. I was able to load up TWRP using this method.

Lenovo TB-7304F (Tab 7 Essential) - stuck on boot

Afternoon
I have a Lenovo 7" tablet which is sticking on boot...to describe:
tablet off, charge screen working fine (green battery)
can get into menu to select fastboot mode or recovery
fastboot works, at least screen appears!
recovery shows dead android/no command screen - how to access recovery?
booting up, get inital orange logo then a 'bing' and start of boot but then freezes on the second logo
tablet not visible on PC, even in fastboot mode (have installed drivers)
I'm looking to get this going but am a bit stumped. I tried reinstalling firmware but can't get SPF Tools to work with any available scatter files; I would like to install TWRP (I found a potential image file on XDA) but can't do this until the PC recognises it....and I'm going round in circles now....any suggestions gratefully received. :good:
Update
OK, post was maybe a bit premature - I've kinda fixed my issues.
Managed to get into recovery after watching many videos (most of which were wrong, but hey-ho, got me on the right path!). At dead android screen, press and hold in power + vol up + vol down together (there is a bit of knack, turn it on its side with buttons facing up seems to be easiest) - this fires up the recovery screen (android standard recovery).
I managed to get over my bootloop issue by performing a data wipe/factory reset and cache wipe, then restarted fine.
As this was a secondhand tablet (my usual purchases - good condition bootloops!) - once it booted up I got into the set-up screens only to discover a Google lock issue. I ran the FRP unlock from here: https://androidfilehost.com/?fid=11050483647474832839 using the instructions from here: http://forum.gsmhosting.com/vbb/f958/lenovo-tab-4-7-essential-tb4-7304f-frp-remove-2322527/ (Voltrans second post, not the original one which has a 404 error on the download site). This removed the FRP lock straight off and now I have a functioning tablet.
I'm probably going to try getting custom recovery on so will see how that goes - I'll post back
and...that's all folks....
OK, despite finding a TWRP recovery online https://twrpbuilder.github.io/downloads/twrp/#441 and downloading it, can I get the fastboot unlocked? no.
Apparently Lenovo locked them all up and threw away the key, so nothing more can be done here.
I tried various iterations of fastboot oem unlock and fastboot flashing unlock, and nothing works, just get an error - and yes, I did put developer options on, OEM unlocking ticked and USB debugging active.... :silly:
So, unless someone can point me in a direction on how to unlock it - I've reached the end of the road with this one

Question Bootproblem and how go back to the standards

Dear Community,
I am a real noob when it comes to Android, flashing ROM, root and so on.
I got a Oneplus here where supposedly root rights are on it and another ROM.
Current problem, as soon as I turn it on it hangs when booting. (Bootloop - red dot with 2 running white dots)
I already tried it with power + volume+. Unfortunately unsuccessful.
Is it correct when I press Power + Volume- that you get into fastboot?
I can't get into the recovery mode either.
I would like to get the device running, but without root rights, OEM lock and the Oxygen OS from Oneplus.
So far my attempts to get it running have been unsuccessful.
Update: after 4h in the bootloop, it booted successfully. *yeah*
So how i can see, if the phone is rooted and how can i lock it?
I tried it with adb, i can find the phone with adb devices.
Then adb reboot fastboot, after that i tried to find it with fastboot devices but then he finds nothing more. the drivers are installed. also fastboot oem lock doesnt work, because the phone is not found.
