cant access anything - Nexus 5 Q&A, Help & Troubleshooting

hello
i have nexus 5 that in the last 3 mounts was untouched because i went back to dumb phone, but now my works need me connected to the internet so...
my phone stuck on the google with the unlock\lock screen, every 2 sec its resets, then again same screen for 2 sec, over and over again.
when i try to get in boat-loader, after 2 sec it again reset and go back to the unlock\lock screen.
when i try to plug it in to PC -nothing
when i try to open the phone and check the power button, it is all good and nothing pressing on the button. and its still loops over and over(didn't tried the "band on the edge" thing -its still plastic and small parts)
if its a motherboard problem can i have a price for it and information how to replace it
and if not i am willing to try any other option
thank you and have great day

The power button doen't need anything pressing on it to be a problem.
Open the phone, remove the motherboard, quickly press and release the power button, using more pressure than normal and try again. If that doesn't work, you may have to replace the power button.
The cheapest way to replace the motherboard would be to find some selling a phone with a smashed screen and a working motherboard.

[Q] tablet won't turn off for replacing digitizer

Hi,
My tf300t got its screen cracked so touch screen is non functional.
I'm trying to turn it off so I can open the case, but it always reboots no matter what I try!
Tried long pressing the power button for 30 seconds but it always reboot after 8 seconds.
Any suggestions? I don't want to open it up while it's on .
Can I shut it down from fastboot mode?

I remember there was a manual Power off option in TWRP (idk if it is still there). Have you tried that?

I have the stock bootloader - it says
Code:
"Adroid cardhu-user bootloader (1.00 e) released by "WW_epad_10.4.2.9-20120809" A03
I'm inclined against flashing a bootloader (only as last resort).
I am able to get into fastboot and issue fastboot commands. will that help?
"fastboot reboot" only reboots..
by the way, the device is still locked (getvar returns "unlocked: no")..

How did you turn it off if the touchscreen wasn't working? By pressing the power button would cause it to reboot endlessly. If you don't have a dock or adapter to power off properly, one thing I did before was to click the reset button (through the hole below the SD card slot) and press the power button simultaneously, then keep holding the power button for 10 seconds after releasing the reset. It did turn off the tab completely. Failing that, just pop off the back cover and turn off the service switch. The cover is not connected to anything electronic so it's ok. That'd cut off the current to the tab. It can be done, just be careful.

I didn't turn it off, that's the problem.. I got it yesterday from a guy after his screen cracked.
he gave it to me turned on and I want to replace the screen, so the only thing I can use are the hard buttons.
I only have the power adapter + usb cable.
are you sure about that reset button thing?
EDIT: found info about the "service switch": http://forum.xda-developers.com/showpost.php?p=46159071&postcount=5
EDIT2: did it! thanks graphdarnell!!
now moving to step 2 - ordering a replacement digitizer..

[Q] [Q} Broken Power Button, Phone won't go into Recovery or Download Mode

The power button on my phone recently has stopped working. I need to get it warrantied, but I am running CM 10.2. I need to Odin back to stock, but I can not get into Download Mode or the recovery. When I go into Download mode, the initial screen pops up, the one where you choose to hit up to continue, or down to reboot normally. After I hit up, the screen goes black and nothing happens.
I really need to get back to stock, as Bestbuy are being dicks, and demanding I do a factory reset before they send my phone in.
Anything? I still need help on this.

This has been covered at least 10 times in the past few months we need a sticky. Take your battery out hold your phone so the power button is facing a table or floor and slam that side a few times it should work again (Temporary). You might need to hit it on the surface really hard 10-20 times before it works. Just not to hard or else you might crack the screen. I used a mouse pad to soften the impact. This trick no longer works for me so I ripped the button off. After about a month of doing this I needed to use things that would only hit the button to make it work. About a month after that nothing worked so I just took it off the motherboard and now boot from a off state by plugging into the wall and enter odin mode deny the prompt and it kicks me into a workable state.

I can get into the system just fine. When I go into the recovery or download mode, it doesn't stay in that mode. I tried the banging thing, and it made my power button go from intermittently working, to not working at all.
keep doing it until it works. The button is sticking that is why it reboots/stopped working.

It sounds like your power button is physically broken, and it is activating intermittently, which is stopping the phone from entering download mode. My only experience with this problem is my own phone but ultimately mine got so bad that I had to rip the button off the motherboard, as ThePagel did. Your symptoms sound the same as mine.
You can try this procedure to get into recovery, which works for me without a power button. You will probably have the same problem you are having now with the phone rebooting on its own before you actually get into recovery, because the power button is activating.
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode. If you want to use Odin to return to stock, do that now.
5. If you want to get into Recovery instead, press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.
If that doesn't work, and you can't get a new phone without returning it to stock, then prying the power button off the phone's motherboard may be your only solution.

[HELP] Unrooted Nexus 5 randomly shut off, now frozen on Google logo at startup

I didn't drop it or get it wet or anything, it was just sitting on my desk and it randomly shut off. I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off. Is there anything I can do to save my data (or even better, fix my phone) or am I screwed? I also don't have USB Debugging turned on so I can't get stuff back that way either. My phone is not rooted and running stock android 5.1.? (Don't remember my exact version but I think I've missed the last 2 minor updates)

I has an issue with it a few months ago with the power button but it was stuck in a constant bootloop (I later found out that the power button was physically stuck, and a few hard flicks fixed it) , now it's just frozen on the google logo for 30-40ish minutes and then it shuts off by itself. Could that still be an issue with the power button?

Yeah, my LG warranty expired so I found a seller on eBay doing it for 25$ (replacing the switch inside)

I'm kinda confused on how this is the power button. On a working Nexus 5, if you hold the power button down the phone just continually resets, now it freezes on bootup and doesn't shut off for a really long time. Then after it shuts off, you have to manually turn it back on (then it just freezes again). I feel like this is could be a software issue but I might be wrong.
I've seen posts saying to reset the cache partition. Will that wipe the data on my phone?
I went into recovery mode (Does this mean the power button is fine, since I could successfully navigate the boot menu) and tried to format the cache and it says it was wiping /cache for about 20 minutes then it shut off and the notification light started blinking red and the phone wouldn't turn on at all when I held the power button. I assumed this meant the battery died during the cache wipe (Is that what the red light means, if so is that bad?) so I plugged the phone in. After about 30 seconds I could turn it on again, but it just holds at the google screen again. I'm really starting to freak out as I have some unbacked up data. Even if I can't fix the phone, is there any way I could save the data? I have a locked bootloader and USB debugging is turned off (Yes, I'm an idiot).
It does sound like a faulty power button. Since it's very cheap to fix, I would first find a local lab to change the button. At least rule out that..
If you can't fix the phone, you cannot get the data.
Also, be carful with bootloader and adb, so you don"t accidentaly erase your data.

The nearest phone-repair shop is like 45 minutes to an hour away from me so I want to be sure this is it. How exactly would a faulty power button cause this to happen? The phone isn't acting like the power button is permanently held down or not held down at all and I was able to get through the boot menu to the clear cache partition menu which requires use of the power button (And has the shut-off and blinking red light interrupting the cache clear made things worse), all that seems to be happening is the phone freezes during boot-up.

This sentence points all fingers at the power button
"I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off"
If you turn it off and it comes back on. it's the power button
Some symptoms of a faulty power button
If your LG Nexus 5 keeps rebooting for no reason to the Google Logo only
you cannot lock the screen
screen locks on its own
phone turns off for no reason during regular use
Lock/power Button is VERY sensitive to touch

The power button is not dead, it's faulty, and behaves erratically. Sometimes it works, sometimes it does not. It's an educated guess. If you put in a lab, and it's not the power button, perhaps they will know what else could be wrong. It's your call.
Just got back from the repair shop, it's not the power button, it's some unknown software issue. They can't fix it. Anyone have any ideas?
This is very odd. I am not aware of any software issue that can prevent a physical shutdown of a phone. Was this a reputable lab?

The phone shut itself off after a period of time, but holding the power button just restarts it. They replaced the power button just to be sure and it didn't fix it.
When you connect the phone to a PC does it show up? Can you copy your data? If not, I don't think you can save the data.
One more thought: If you put the phone in bootloader state, does it still shut down or restart by itself?
I just talked to the phone repair people and they said they just found out it's not software, a circuit in the motherboard got fried and they only way they could fix the phone would be to swap out the motherboard.
That is a 200$ reapair. Before you do that or give up on your phone try my guide here http://forum.xda-developers.com/google-nexus-5/help/nexus-5-stuck-boot-loop-lollipop-t3098632
I had a different problem but was also told by the local LG lab that it was the motherboard. It wasn't,
If my guide does not help, it probably is a hardware issue. See if the lab has an insurance deal. Over here they suggested to sell me a one year insurance for 150$ , and change the motherboard. That would have saved me 50$....

Power button stuck, can only get to fastboot

My N5 has a hardware fault where the phone thinks the power button is permanently pressed, so as soon as you try and boot it, it turns off again.
I am able to get to fastboot, by holding down the volume down button and power. But from there, I cannot boot to recovery or normal system boot.
I have been unable to fix this, and I really want to get some of my app data off.
Is there a way of extracting a backup somehow from fastboot?
I'm guessing no, as you can't access via adb through fastboot can you?
Any ideas gratefully received.
Did you try removing the motherboard and cleaning the area around the power button with alcohol? I had a sticky power button too and removed the motherboard, applied a lot of pressure to the power button as I pressed and released it for a couple of minutes and this solved the issue.
I had this issue, took apart the phone, didn't fix the issue. Read a thread were multiple owners said smacking the phone on a hard surface on the power button side fixed it.
So I was hesitant but after a few hard taps, it fixed and haven't had the issue for 4 months so far. I also pressed the power button a few times hard.

Hi. Yes, I have tried all those, no joy.
I'm resigned to the fact the phone is bricked.
So, given that, do I have any options to get the app data off?
Merry Christmas by the way!
I suggest getting a quote to replace the power button.
Wonder if I can desolder it, and use a paperclip to short the switch connection?
There are 3 connections for the motherboard for the power switch and it looks pretty easy to de-solder according to youtube videos I watched. I'm not good at soldering so I had my local repair shop replace it with a new one.

Nexus 5 - Hardbrick ?

Hey guys,
I need some urgent help.
My Nexus 5 device is not booting. It stucks at the bootlogo then powers off and restarts again.
Normally it wouldnt be hard to fix such an issue but the problem is :
I can't boot into bootloader (bootloader appears for 1 second then phone powers off)
I can't boot into Recovery mode (Recoverymode appears for a second then phone powers off)
I can't get my phone into fastboot mode, - it appears for a few seconds durign the bootloop as an "unknown device", but I am not able to flash a new bootloader/factoryimage.
I tried like every possible option what I can do, but nothign worked for me.
What else can I try since I can' get my phone into fastbootmode?
Bootloader is unlocked
Secureboot is enabled
(from what i can see in these 2 seconds where the bootlaoder pop's up)
Is there a way to recover my nexus5?
Symptoms of broken starter button
Posté depuis Nexus 5 / Miui7 by Miui-France
Remove the motherboard and clean around the power button. When you have cleaned around the power button, quickly press and release the power button using more pressure than normal a few times, try to boot again.
Thanks for the tips!
I never thought that a broken Button could cause this issue.
I will check it as soon as I am home.
But how am I supposed to clean the motherboard, and I don't understand how cleaning the button from the outside
of the case should help to solve this problem.
Can you guys explain it a bit more detailed please? ^^
Are there good and very detailed tutorials for this?
And yes, you ideas definitely make sense because some days earlier when the Nexus5 was still
booting fine, I remember that I sometimes had the issue when I turned of the display with the power button
it instantly turned on again and I had to turn it off like 3-5 times until it really was off (standby).
To clean around the power button, you'll have to disassemble the phone which is not hard to do it you take your time and use the right tools.
https://www.ifixit.com/Teardown/Nexus+5+Teardown/19016
I noticed that the issue really was the powerbutton, - however the button was broken and
not repairable by cleaning. To repair the phone I would have to purchase a new motherboard.
In the end I decieded to purchase another phone, just saying that if someone will have the same issue in the future
try to clean first, if that wont help the powerbutton is most likely broken, and this results in a new motherboard-purchase because
the button is not repaireable by hand
The power is replaceable if the damage is confined to the power button itself.
