[Q] Nexus 5 Black Screen - Urgent - Nexus 5 Q&A, Help & Troubleshooting

Hi Guys,
Tried switching SIM cards on my Nexus 5 after getting back from holiday, only to find that the screen now never turns on. I can see the phone listed on windows (not ADB) and it vibrates to power buttons etc. My urgent question is, is there ANY way to recover the data from my phone at all?
This is urgent due to me having to send this thing back to Google by tomorrow for a replacement.
Cheers,
David

Have you tried forcing a reboot by holding down the power button for 10-15 seconds?

And thankfully, it turned out that the phone is working fine apart from the screen, remembered where to tap my PIN code and all is well with the world again. Thank GOODNESS. I know you guys would do your best to help anyway
Just out of interest, has anyone else had this issue before?

[Q] Galaxy Nexus Boot Loop (stock)

I have an unlocked HSPA+ Galaxy Nexus imported from the UK to the US. Ordered from Negri Electronics.
It's not rooted or modded in any way.. Mainly because I don't know how to. As far as I know, it's running stock ICS.
I was using it normally, (using the fb messenger app if it makes any difference) when it suddenly rebooted by itself. The Google logo comes up, then the start up animation, and sometimes the home screen will appear but is not touch sensitive (i cannot slide it to unlock), and then it 'hangs' and the screen goes black. Repeat.
I've tried to fix this by myself and there's a video on youtube (sorry, noob here. can't post links. video is by robbidwv and title is "my galaxy nexus won't boot..") of the same problem that I have, but the posted solution doesn't work for me.
So far, I have entered Coin Mode and pressed Start. Entered Fastboot mode and gone into Recovery Mode (no options appear after that. it just starts booting up and the loop begins), and I've also tried Restart Bootloader.
I've almost given up. Now all I want is to extract my SMS, if they're still on my phone. I can't access the folders on my computer because it won't boot up and connect. Is there a way that I can extract my SMS by using DOS in either Coin Mode or Fastboot mode?
Or even better, does anyone have a solution to this boot loop problem? I'll contact Negri Electronics tomorrow and hopefully they can send me a replacement.
Please help!! Thanks
that problem just started happening with me an hour ago!!
i hate this!!
we need a solution please!
Hey guys, sorry about the issue.the major problem I see here is you wanting to retrieve your txt messages, which might be possible with a little Modding, but if yourwilling to lose them to get a working phone back, then this is what your going to have to do. Make sure your phone is completely off. Hold the 2 volume buttons and the power button together. You will get into a mode with an android Guy. Press the volume button up or down until it says reboot recovery at the top. Press the power button. It will rebootand come to a screen with an android. Hold volume up,down and power at the same time. A menu will come up. Go down to wipe data. Click it, and after it is done reboot. Your phone should work now.
If this helped you, or you simply appreciate me taking the time to write this out then please press the thanks button
Hey!
Thanks. Yeah I 'fixed' it already. I was just about to post something similar. After a while I just gave up on trying to recover my data. Good thing that Google syncs everything so the only issue would be recovering my messages, which I decided weren't worth sending it in for a repair which would probably not be able to recover anything anyway.
The thing I didn't know about was to press power + volume up WHILE on the recovery screen. I thought navigating to the recovery screen was it!
Still, this kind of sucks. I love my GNex, but I can't help but be slightly pissed seeing that my crappy iPhone 3GS never did this in the 2 years I had it. Oh well, hope it doesn't happen again!
hey guys! i also did a complete wipe on my phone and got it working again!
but i wonder why this happened in the first place?
last application i installed before the crash was double twist, i dunno why but i feel that it was the reason behind the boot loop!
Sorry for reviving this thread, but I just had this happen to me TWICE!
It happened to me first last Monday, the 23rd - the phone crashed when trying to send an email with an attachment - and went into a boot loop - Google logo would appear, no make it to the animation, and reboot....
I performed a full reset and things worked again. I didn't install all the apps I had before - figuring it must have been due to some app messing with the OS.
Well, it happened again to me yesterday! I was connecting to my bluetooth headset when the phone crashed and went into the boot loop. Full reset worked again, and I've installed even fewer apps - essentially only those that I use on a daily basis.
My phone is still on 4.0.1 and I'm hoping once 4.0.4 is pushed this may get resolved? I have a canadian GNex from Negri. I will call them again (I called the first time, but when the full reset worked I never contacted them again).
I would like to this this is a software issues, and not hardware.
I have the same problem. If you figure it out let me know.
Today my phone also entered a boot loop: [Google logo]->[black screen]->[vibration]->[Repeat]
I tried Recovery Mode, but this is what happens: (sorry for the link but I am not trusted with powerful tools such as outside links apparently, as I have not yet reached the maturity of a person with eight posts... )
dl(dot)dropbox(dot)com/u/53568097/Android.jpg
This is what I see when I navigate to Recovery Mode
For a split second I can see an image of an Android with spinning cogs in his innards, but then this little sad fellow appears. WTF is this?
EDIT:
Oh, and I'm running Android stock 4.0.2, never rooted or unlocked, Swedish. At the time when the phone started doing this, I was using Endomondo, and was about to set off on my bike when it died on me.
Stock ROM galaxy nexus bootlooping after wiping data also.
Hi,
My GNex went into a bootloop so i searched xda and found that factory reseting would be helping my prob. But after wiping the data also its still in going through the loop . Please help .:crying:

Weird problem with Nexus S...is it dead?

Hello everybody,
recently my brother's Nexus S started having problems. The battery life was awful and 4 days ago the power button stopped working. We were out, so i disabled the lockscreen. That way pressing the volume button would turn the screen on. This "trick" worked quite fine until yesterday, when the phone shut off, I don't know why (maybe the battery went out?). I tried to turn it on again, but there was no sign of life whatsoever. Not even volumeup+power button produced any effect. I then read on this forum and it looked like the motherboard is gone. Thinking that the phone was gone, I searched a way to recover photos and text messages from the phone(always remember to set a periodic backup). After a couple hours of pointless research, I gave up and went to sleep. I turned off the lights and I saw a flash. It was the Nexus S. So I filmed it and uploaded to youtube. Here's the link: http: // youtu.be/oGSVjElAwq0 (remove spaces) You can see the screen blinking a couple times(around 0:07 and 0:27). Maybe the phone is not completely dead and there is a way to recover that files or even save the device. Unfortunately I'm not expert, so I don't know how to proceed. Any help is appreciated. A big thanks in advance.

Hi, please try to answer these questions. Might help solve your problem.
When you plug the phone in, do the capacitive buttons light up?
Does your phone get recognized on your PC when you plug it in via usb?
Are you 100% sure this is not just a battery issue?
Hi, thanks for your time
-No, the buttons do not light up.
-No, the phone does not get recognized by the computer(i tried Windows and Ubuntu)
-I can't exclude a battery problem, but ,even that, it should power up when connected, shouldn't it?

[Completed] [Help!!! Urgent!] Power button stuck! Data recovery

Hi all. I need your help. My Nexus 5 suddenly began rebooting and not turning on. I made my homeworks an I found out it's the power button stuck in (not phisically, phisically is fine, it must be the inner switch or something). I tried smacking it on the side to unblock it (aka the Fonzie solution) but it didn't work, also tried massaging it, and it's no good. I tried to move the inner thing with a magnet and after various long minutes of rage and precision work I managed to make it boot for a couple of minutes, it didn't even fiinish optimizing apps, it was flat on the table, nothing touched it. I already wrote google for an RMA, but how can I recover my data without opening it? Is there a way to disable the 10 seconds force reboot behavior, or to disable the power button totally? I don't care about the phone, I just want to recover my data without loosing warranty.
Come on guys, do your magics. I'm counting on you.
Hi there,

help, screen off, mobile ON stuck, can't reboot mate 8

Hi
Mate 8 was working flawless until today, my screen seems totally Off but the mobile itself is on. I can't find a way to force thereboot as this requires the screen to be touched, anyone was a solution as there is no english manual for this device ? I see a small hole on the top that i guess is for something. Does anyone had that problem and knows hos to soft reset the phone ?
You can hold the power button for 10 seconds, for soft reset. Did you try this ?
unfortunately yes, screen remains off while mobile is on. I can recieve calls but you cant do anything as the touchscreen remains off ... I think this looks to be a hardware issue. ****, i ve paid this device 829 USD from ali baba to get it quickly and now it will take ages to get another one from them, hoping they wont make any trouble.
Try hold vol Up and power button. Chinese menu should pop up, use a camera translate with another device(i forget what is what) format clear cache.
But of course it could be your screen is toast.
Screen off, phone still on just happened to me, too. After a while it rebooted by itself. Have the phone for one day now, this is annoying the crap out of me.

u12+ black screen after PIN unlock / Device unusable

Hi everyone, I'm throwing this out there because I've run out of ideas about what has just happened to my U12+ (64gb) today.
I woke up and used my phone as normal, caught up on Twitter and the news, the usual apps etc. nothing untoward. The same routine I've had with my phone for the past 18 months of owning it with zero issues. My handset is stock OS (Android 9) and so not rooted or anything like that. Virtually all the apps I use are standard issue from the Play Store, nothing really "out there" and I have BitDefender installed to look after security. Same setup I've had for over a year. The battery was around 35% so I plugged it into my wall charger while I went off to grab some breakfast. When I returned a couple of hours later the light on the handset was green, I unplugged the charger and attempted to unlock it with my fingerprint.
The phone asked for my PIN, no big deal so I entered it. Black screen. Tapped the power button again, it requested my PIN again, I entered and... black screen. Okay, I was a little bit concerned now. I held down the power button so the haptic buzz occurred, held for 10/20/30 seconds, a minute... nothing, no restart. Tap the power button and it asks me for my PIN again and shows yet another black screen. I held down Power + Volume Down but again, nothing and no restart.
I asked someone to call me, the screen came to life and I could take the call but each time I tried to pull down the system tray in order to try and reach Settings to restart it asked me for my PIN, I entered it = black screen. The call was unaffected.
I removed my SIM + microSD card tray = same deal as above.
The phone is clearly responsive in some way and the screen does display to ask for my PIN but I can't get into it in order to reboot it. Extremely worrying.
Does anyone have any advice? At the moment I am faced with the prospect of simply allowing the battery to run out so the phone shuts down naturally but that is going to take the best part of 2 days.
I'm really disappointed because I was planning another 1-2 years use for this handset as I just bought a 1TB microSD card which has been fine in the phone for weeks so I don't think that's the cause. It is also genuine SanDisk.
Any suggestions or advice? Thanks in advance.
Hello, I hope you have made a backup with google backup recently... This does not happen often on android, but sometimes the system could have a problem. You can try this go the bootloader with the power and volume buttons , after recovery.. after apply a wipe data/ factory reset.. is will make a factory reset of your phone except the sd card. You should by fine after that and profit again.
Thanks, I appreciate your reply.
At the moment I am running the battery down until the handset switches off naturally. When it comes back on I will try to launch the phone normally, if that doesn't work I'll run the battery down again and attempt to reach the bootloader.
My photos are backed up to the cloud, I may lose some text messages but I managed to transfer the majority of my 2FA over to another Android device bar one.
At the end of the day if it's a choice between wiping it or a bricked/unusable handset then I don't really have one. What a pain.

At the moment I am running the battery down until the handset switches off naturally <----- why that??? Even on a bootloop or a black screen you can reset it hold the buttons power and the volume, you can go on the bootloader.

The first thing I tried to do was hold down the power button or the power button in tandem with the volume buttons but the handset won't restart. I tried loads of times holding it for different amounts of time and... nothing.
Trust me, I tried.
The only way I can get the device to switch off is by draining the battery. I'm almost at 20% so it shouldn't be too much longer.
Well I already got a black screen after flashing a module magisk.. I have holding the power button and the phone have restart no problem, same thing on bootloop. You need to be sure to hold the button correctly.

Yeah, I'm certain I was holding the buttons correctly. I tried about 20 times using different combinations just to be sure but the device would not restart. The haptic shock buttons are one of my least favourite features of the u12+, it's got to be said.
Anyway, the phone ran out of battery about 15 minutes ago. I left it alone for few minutes and switched it back on. It allowed me back in and the device appears to be fully functional again. I can unlock by thumb print, face or PIN without issue.
Basically, it's fixed. My only concern is I have no idea what caused it or if it will happen again.
Thanks for offering help though, I appreciate it. I'm not sure if this thread can be closed/locked now? I'll look into that.
Cheers.
Yes.. i love the buttons too i never got a problem with this. Great if is fixed! Maybe make a factory reset the next time.
I am wondering if the new flagship have haptic buttons too.. htc will announce it Tuesday.
