[Q] N5: Powerbutton weird behaviour - Nexus 5 Q&A, Help & Troubleshooting

Hello!
My nexus 5 got some seriously weird problem yesterday.
1. it turned itself of
2. It rebooted and rebooted and reboot. So okey, just a regular boot loop. But the reboot was inconstant and never followed a pattern.
3. I tried to go to bootloader: It worked and it stayed at boot loader for about 1 second and i rebooted.
4. I hold powerbutton and shaked the phone and it finally booted.
5. I touched the powerbutton and it started rebooting and loop again.
So i was thinking that the powerbutton had been stuck but it wasn't stuck, or at least it didin't feel stuck.
I called the shop and Im going to show the phone for warranty tomorrow so I relocked and unrooted (reset) my phone and now I am not ably to recreate the problem anymore..
This is really weird because it seemed like a obvious hardware problem.
Anyone has an ide what is going on?
Cheers!
PS. I flashed Lollipop 4 days ago

Nexus stuck at update screen (droid with polyhedron)

My Nexus 5 seems to get stuck at the update screen (the standing green android with the spinning polyhedron) after flashing to stock(+unroot) with softbrick/bootloop checked. The flash completed without error. I've left it at this screen for over an hour and not only does it not progress it doesn't even get to the progress bar at the bottom.
This afternoon my (unrooted, bootlocked, stock) N5 turned itself off 3 times while on the charger. Powered back on and then would find it turned off 20 or so minutes later when I checked it again. After the third time it booted to the "Google" screen and would go no further. I tried a hard reset but it gave an error. So I plugged it into my laptop and fired up Wug's NRT, unlocked the bootloader (at which point it got stuck at the same update screen described above for around an hour). I held power till it went off, booted back into bootloader (which showed as unlocked) and performed the flash to stock(+unroot) with softbrick/bootloop checked and ended up at the update animation again. Any thoughts other than RMA?
****Edit: Finally got the phone to boot after fastboot booting twrp. Was able to to wipe the phone (after multiple attemps blocked by can not mount storage/cache/etc/etc errors). Flashed 4.4 and the phone now boots to android BUT radio is non-functional (no signal despite being in my normal coverage area), any attempt to add an APN causes a hard reboot (had to go through all the setup screens again). Additionally, the phone won't turn off, even hard power downs (holding the button for 30 secs) lead to an immediate reboot. Still RMAing but I was able to relock the bootloader.
You really shouldn't RMA a phone after messing it up yourself by using a toolkit when you didn't know what you were doing.
Flash the factory images manually. That should get your phone up and running again.

Performed a manual flash with the exact same results. There is apparently something wrong with the hardware (which may explain why it was turning itself off and then wouldn't boot past the google logo.

Yep, I would agree.

My Inspire 4G (randomly?) stopped successfully booting and cannot access bootloader

I have a rooted and bootloader-unlocked Inspire 4G. A few months ago, I had been using the MoKee 4.2.2 ROM for some time, and one day, my phone's screen simply froze. I thought I shouldn't be worried about it, so I pulled the battery off, slapped it back in and tried turning on the phone again. It never got past the MoKee loading screen. I tried charging it, leaving it to boot for hours but nothing.
Next, I tried rebooting into CWMrecovery to try different stable backups I had from some time before that happened. The backups restored successfully, but again, the phone stayed stuck in the loading screen. I tried the same with 4EXT Touch Recovery and wiping all the data before the backup, but still nothing worked.
Since I was too busy at the time to install a new ROM and flash a new boot image, I decided to put the phone away and use my backup Galaxy Ace. Today, a few months after that happened, I tried to boot the phone into bootloader and I can't even achieve that. Holding the volume down rocket and power buttons, the phone still boots normally and stays stuck on the loading screen.
What weirds me out the most is that this was all random--I did not drop the phone or did things to it that could break it.
I feel if I could get into recovery I'd be able to do something else about it.
Any ideas?
Me too
Weird, mine just did the same thing today. Crashed, had to pull battery, now stuck at Mokee. Tried clearing DC, cache, factory reset. No luck.

[Q] N5 dead? multiboot issues?

Hi, my Nexus 5 was just powered off as i clicked the power button to browse the web. I tried to boot it but it just went to multiboot and restarted after 2 seconds.
It kept restarting like it was bricked but shut off after a few times. Then i booted into bootloader but the screen went off after 2 secs. I removed the battery and put it on the charger but it just boot loops the google logo.
I am on Xtrasmooth v9.0 if you want to know but i dont think that this has any importance since my phone doesnt stay in the bootloader which has nothing to do with my rom (i think):good:
But maybe it has to do with multiboot? I have to say that my phone kept randomly restarting over the last week.

Have you tried restoring to 100% stock with a factory image?

Nexus 5x google bootloop, recovery won't get past Google screen either (strange)

I was in snapchat when all of a sudden my nexus 5x totally froze and rebooted (which is normal considering how much snapchat sucks.)
I saw the warning about my bootloader being unlocked which was normal and it went to the Google screen, where it sat for about 5 minutes. Normally in every previous bootloop I've had in the past, the boot animation just loops forever and ever. I force shut it off and tried booting it up again and this time on the Google screen the phone totally shut off and restarted showing me the warning about my bootloader. I tried the recovery, but got the same results. So, I went home and plugged it in thinking maybe that would help but it still was shutting off and rebooting. It never got to the boot animation. I had all the adb and fastboot drivers so I just decided to flash the factory image. It flashed fine, and sadly the problem was still there. I'm so stuck, I can't get into the recovery to do anything and there's only so much that you can do over fastboot. I've found that if I press the power button every couple seconds while the Google screen is still showing and it doesn't reboot but the Google logo won't leave for the boot animation.
Seriously guys, please just give me any of your ideas.

Samsung Galaxy S7 boot and freezing issues

I've had my S7 since March. Worked flawlessly until around 2 weeks back. The first issue I got was that the phone stopped responding. I haven't linked that to any specific application. It happened at random. So the phone freezes and screen goes black. I used the Power button + Lower Volume button to power up the phone again and it worked. But then the no response problem happened more often. So I decided to go for a factory reset. I did this using recovery. But I continued to get the freezing issue. And the last time I got it was a few hours ago. But this time when I used the power button+ down volume button, the phone got stuck in a boot loop. I managed to bring up recovery to power down the phone. When I booted into recovery, I got the a dead android logo with a yellow exclamation mark in a triangle. I tried to power up my phone back, but it again got stuck in a boot loop. I know I can resolve this situation by doing a reset again. But I suppose this is not the solution as I will continue to get the freezing and not responding problem again.
Any advice please?
Thank you.

Hi mate
after you factory reset it , did you use the phone for a while without restoring any app?..so you are sure is not an app making the mess
My first option would be flash ( odin) firmware again.....
Check his guide
Use home_csc instead of CSC so you do not lose anything
I actually didn't restore any app after reset. I rather re-installed only 2 apps I use most. And I've been using these apps since I started using my mobile. I don't think they could be responsible for the crashes.
If I have to flash, I've been wondering if I could have a go at Nougat.
Would that be a good idea?

Hi
Yes you can flash nougat, seems to be stable......but still is a Beta version
Hi
I got the same problem ... did you find any solution for this problem ??
Replacing motherboard fixes this issue. Its not software related. Faulty board. With Nougat this will happen even more. I know because happened to me..
ohhh
how much did cost you for that ?
