[Q] Nexus 5 stuck in bootloop - won't stay in recovery mode - Nexus 5 Q&A, Help & Troubleshooting

My Nexus 5 phone started rebooting spontaneously at lunch today. I've now spent hours on XDA and other forums attempting a factory reset/wipe. I've tried the built-in recovery mode and factory wipe/reset (http://forum.xda-developers.com/goo...ide-nexus-5-how-to-unlock-bootloader-t2507905), WugFresh and XDA described one: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701. Everytime the results are the same - my phone reboots partway through the process. Since lunch the phone hasn't gone more 30 seconds before it decides to reboot of its own accord.
I'm at loss as to how to debug let alone resolve. My gut says this may well be a RAM problem in which case this is now my old phone. How would you tackle?
Thoughts?

Stuck at "erasing" when doing a factory reset?

Anyone else had issues performing factory resets? My Nexus 5 seems incapable of completing it. So far I have tried doing a factory reset from the settings menu 4 times. Every single time it locks up on the erasing step. I don't mean it takes a little longer. I have let it sit for almost half an hour and the little android robot sits there taunting me.
Every time I have had to manually go into the bootloader and sideload a factory image, which works fine.
Any ideas why this problem is occurring? Faulty memory maybe?
Same issue here, phone is getting nice and warm but the little robot just sits there twiddling his antennae. Forced restart either normally or into recovery mode lands me right back on the erasing screen, looks like nothings going to happen unless I intervene another way. Any ideas?
Try pushing the system.img using fastboot. Might be best to start over and do a clean install.
Have you tried doing a factory reset in recovery instead?

Same problem
I have the same problem with the loop at the erasing screen. It will not go into recovery so that I can fix it. I tried flashing the Stock Rom again but no use. Please help me or at least give me some pointers what to try next.

What is your recovery? Version # also? How did you root? <--- this goes to the rest of you guys too because it seems like its happening to more than one person.
Follow this: Maybe flash the stock recovery found in here http://forum.xda-developers.com/showthread.php?t=2513701
fastboot flash recovery C:/image-hammerhead-krt16m/recovery.img
^^ the command
edit: on second thought start over.

ADB sideload: place the rom you want to flash in the fastboot folder and in the phones recovery select adb sideload, then on the pc in cmd type: adb sideload namerom.zip and it will start flashing.

but i finally found out that the stock recovery was somehow corrupted after factory reset
then I unlocked the bootloader and flashed TWRP recovery, and voila! my device booted normally
Nexus 5 hung at reset

Exactly the same problem here. Nexus 5 running 4.4.2 kept powering off randomly roughly once a day. Attempted a factory reset and it got stuck at erasing. Having unlocked the bootloader and following the steps to unlock and reboot, I have a progress bar with the animated android icon, apparently stuck at the same stage, but without the "erasing" caption.
As far as I'm concerned, I can nothing with the phone at present short of taking it back, though they'll likely take issue with my attempts to rectify myself

I'll add that I've also tried the Nexus Root Toolkit v1.8.0 to flash stock. Appears to go fine, recreating the file system and loading software, then as soon as it gets to the "erasing cache" step it just sits there for hours and makes no progress.
I know I probably shouldn't promote toolkits but you can always try this. Seems to have worked for a lot of people.

Same thing happened to me yesterday. My N5 is rooted, running stock rom and recovery. I had some corrupted app date showing in Titanium that I could not remove that were causing a Play store issue for me. I backed up my phone with TB and ran a factory reset in settings. The phone was stuck on the 'erasing' screen for maybe 20 minutes, so I put the phone in fastboot and from there back into recovery. This took me back to the 'erasing' screen to my dismay. I put the phone down and started searching for a solution online, but then I noticed after about 7 minutes the erase process had finally finished on its own and the phone rebooted normally again.
Based on what others are saying in this thread it appears the factory reset process via settings or stock recovery can hang sometimes. If you power off, start the phone in fastboot and select recovery again, I'm guessing the factory reset process restarts and hopefully it will then work properly the next time, like it did for me.
Well when I did a factory reset from settings, it took nearly 20-25 minutes to finish. The next time I did a reset, it completed within 10 minutes
I guess this problem occurs randomly.
Be patient
My guess is that you just need to be patient -- my device took nearly 45 minutes to reset. It seems to me that the time required is proportional to either the amount of data or the number of files you have on the device. My device had a mix of large files (such as musics and photos) and many many small files (sensor data log files), so it's hard for me to say which of those contributed more to the long reset time.

This worked for me too. On the initial 'Return to factory defaults' it got stuck for about 45 minutes. I then follow the advice above:
- Put the N5 in Fastboot by pressing: Vol. Up + Vol. Down + Power
- Select: Recovery and press on Power to proceed
- Phone reboots, still into the 'Androidman' but it seems that the 'Return to factory defaults' also restarts.
- Wait about 10 minutes and the Phone powers down automatically. Upon startup you enter the 'Initial configuration menu' so the factory reset has been completed.
Still stuck on Erasing screen, running out of options
Hello,
I am a newbie with zero developer knowledge and received my Nexus 5 in the mail yesterday. I liked the phone specs and that is the only reason I got it. I left it alone while it charged up and the first thing I did once it was finished was perform a Factory Reset (it was a "like new" phone so I just wanted to be safe) and have been stuck on the Erasing screen ever since. Pressing Vol- and Power button does take me to the bootloader screen, however, any option I choose by pushing the power button, such as Recovery Mode, sends me back to the Erasing screen. Pushing Vol+, Vol-, and Power shuts the phone off completely. Holding the Power button down does nothing more than restart the phone into the Erasing screen. I have also let the phone die twice and as soon as it has enough juice to come back on, it goes straight to the Erasing screen. Everything on the phone is stock and it is completely unrooted. The bootloader screen also indicates it is unlocked. I have attempted to flash it as per instructions I have found on here but I am unable to download the stock factory images. It gets to about 90% before the install fails and I have tried to install three times already. I do have the 15 Second ADB installed, however. I assumed the install of the factory images failed because I don't have WiFi and I'm running completely off of limited 3G data (I live in the middle of no where with no high speed internet to speak of). So in lieu of all that I have attempted, is there ANYTHING at all that can be done to get the phone off of this Erasing screen? Or do I just need to try and return it because it's useless at this point? I did at first let the process run but it's now been 24 hours stuck on this Erasing screen with no improvement. I'm fairly certain it runs KitKat 4.4.0.

Nexus 5 Misbehaving

I have a nexus 5 running android lollipop with franco kernel. I tried to switch off the device by clicking on the turn off button, but somehow the device randomly reboots. According to a few forums I should try and wipe cache which I did and still the phone refuses to work properly. I tried to factory reset my device but then the phone refused to boot into recovery and rebooted again. After sending ADB commands too it refused to boot into bootloader mode. The factory reset button on the device also was not able to wipe it. I am really worried since my nexus 5 just ran out of warranty a week ago. Is there any solution? I appreciate any help I could get.

[Q] Nexus 5 factory reset fail - red triangle / erasing

Hey there, I have an interesting problem with my nexus 5.
Since the update to 5.0 (sideload) the phone was laggy and not responding well.
I waited for the 5.0.1 OTA, hoping that it would solve the problem. It got better, but the performance still didn't feel right.
I decided to do a factory reset today, which seems to have failed somehow...
I chose the option through the settings menu, the phone powered off and the erase android came up.
The erase was on for approx 10 minutes, then the red triangle android came up. While I was checking for solutions on google, the phone went back to erase and is stuck there now since approx 30 minutes - not sure if I missed a repetition of the above in between.
I couldn't find anything matching in the search - please let me know if anyone has seen it before and/or knows a solution.
Thank you!!
Edit:
Problem solved - I forced reboot a few times and at one point it booted as normal.
No idea what caused the problem - anyway, it is back to life.
Sorry for the panic - close,please...

S6 failing to boot - stuck on factory reset

Hey, my phone has been playing up and generally malfunctioning lately. It seems to work fine for a day or so before freezing, and either rebooting itself or forcing me to manually reboot it using power + volume down. This seems to send it into a bootloop where it generally freezes during the Samsung animation with the pulsing squares. This sequence continues with me manually rebooting, also trying to boot to safe mode and to recovery and after various attempts, i successfully got into recovery without it freezing on the blue android.
I then decided to factory reset as a last option, having looked around on forums for solutions. However, I now do not know what to do as it seems to have frozen during the factory reset. I dont have screenshots but the script reads as follows :
dm-verity verification failed. . .
-- Wiping data. . .
Formatting /data. . .
Formatting /cache. . .
It has been on that for the past 30 minutes and so i have assumed it has frozen. I'm afraid to force another reboot in case it is accessing memory, any suggestions on what to do?
It is up to date on fully stock software, has never been rooted and i have never attempted to do so. Also only around a month old.
Any help would be appreciated, thanks
I did not try to perform a factory reset yet, but my S6 shows the same instability issues.
Random self reboots with getting stuck at the boot animation.
I furthermore cannot enter the stock recovery mode (get stuck at full cyan screen with android logo), only can access the ODIN mode atm.
Booting that device atm is a hit and miss.
(everything stock, never touched that device in the XDA way! )
Update: I had to repair my S6 as instability increased even more.
Samsung licensed repair shop exchanged the mainboard of my S6.
All is fine again (except wireless charging, but I guess they broke it while repairing)

GM1917 stuck in bootloop after MSM tool

The short story is that I used the MSM Tool to try reset my OP7 Pro completely back to stock. I have the US/Global variant (GM1917). The image I used is the guacamole_21_P.31_201105 (found on this thread under GM21AA tools -> Android 10 -> OOS 10.3.7: https://forum.xda-developers.com/t/...0-gm21ba-collection-of-unbrick-tools.3956595/)
The MSM tool completed its work with no errors and the phone rebooted after it completed. On the first reboot it spun on the red dot and white circles screen for a few seconds before rebooting itself again. On the second reboot it stayed on that spinning dot screen for 15+ minutes, after which time I powered the phone off. I can get into fastboot/recovery. My understanding was using the MSM tool should basically completely reset back to the factory image, am I doing something wrong? Is there anything else I can do at this point or is the phone just hosed?
Longer history
The phone was originally unrooted, stock, locked bootloader, etc. No changes done by me. The phone started having a few random reboots yesterday (and some games I were playing started throwing random security violations or just outright closing themselves). This morning the phone itself started rebooting every minute or two. This had also happened back in October and only after about 4 or 5 factory resets did it finally stabilize itself. Instead of going the same route again I did some search around searching around. I decided I'd try to replace the kernel with arter97's (https://forum.xda-developers.com/t/r64-arter97-kernel-for-oneplus-7-series.3952578/) since it seemed like the OS itself was randomly crapping out. I unlocked the bootloader, installed TWRP (twrp-3.5.0_9-0-guacamole.img) and Magisk (latest version) first in the same recovery session with no reboots in between. I rebooted and was having a bootloop issue at that point, but figured I'd proceed with the kernel update as well to see if that resolved it. When that also didn't help I decided I'd try to go the MSM route.
