nexus 4 doesn't wake up from the power button - Nexus 4 Q&A, Help & Troubleshooting

I have a problem with my nexus 4
I am using stock 4.4 latest one and I am rooted and using closed fw
The problem is when I wake up I found that the alarm doesn't wake me up and th e phone is like shutting down I think it's freezing on the black screen and I cannot open it from the power button and I have to long press the power button to shutdown it and press it again to power it on and I found a missed alarm I don't know if that from the KitKat or from the root or what actually I didn't had this experience on JB
So if I can solve this just let me know Guy's
thanks

What happen when you plug in charger in it , can u see anything on screen , try charging your battery externally with a external charger , it's always good idea to start with simple steps

What about a broken power button? I've replaced a bunch of them on sgh-t989, so what if it happened to the n4? I've been using mine ever since it was released in 2012 and there's no issues, but you never know... Just my first thought...
Also, the proximity sensor/headphone jack ribbon cable can be disconnected without affecting the usability of the phone, so i guess he could try doing that, if you say that it might need replacement of it.

Have u got chance to check proximity sensor , as other member suggested just remove sensor n check , it will even work without sensor but u may find your problem

4.4 will not boot with proximity sensor/headphone jack cable disconnected - n4 will not boot past boot logo ...

Rolf2 , is it a new question ? U should start your own thread

no, this is answer about proximity sensor , do you see question mark ?

no
Power button is OK because I can power it off and on again from it and prox I think it's OK I don't know

I have the lock unlocked, and I still can't get the screen to rotate at all (for Chrome, Gmail). Any ideas? It's plugged in and charging, would that cause a problem?

Nevermind, I think I solved it... Wasn't holding it properly, I need to hold it at a near 45 degree angle and it rotates just fine.

Shouldn't be a problem. If you see a lock on the drop down that you do not have rotation unlocked...

Cracked screen, sending device back to LG, but need to wipe it first, without screen

My screen cracked on my N4 and I am sending to LG to get repaired. I want to wipe the device first, but my screen is unresponsive. I don't have USB debugging enabled, but I can see my N4 directories if I plug the phone into the PC.
Is there anyway to flash images or even power off the device? I can turn the screen on, but the screen won't work. So I can't even power it off or boot into bootloader. Any ideas?
Well, I figured out a way. I remembered I had Cerberus installed with the ability to wipe the phone and SD card remotely, so that is what I did.
If the phone is on/ awake hold the power button for about 15secs. Then boot into recovery, up col and power I believe, then wipe data. Not sure the button combo to do that though. Probably up then down x 3 then power. But don't quote me. I don't have my N4 yet so if someone can try it and record the exact button steps that would be great.
This is assuming you don't have a custom ROM or recovery.

So it wasn't rooted or custom ROM or boot loader unlocked etc?

Also...funny thing is, I had an RMA with google already because I had yellow tinting on the screen when it got warm. The RMA arrived the same day I cracked the screen. So I called Google and told them and asked if I could just buy the new one and not send my old one back. They said that was fine. So, when the cracked screen gets fixed by LG, I will have an addition N4.
I'll take it for $325! Lol you know,as a helpers bonus...or something

Hard bricked Nexus 7 Screen not working,

Device : Nexus 7
Running : Android 4.1.2 Rooted
Problem : I was trying to unroot it and flash a 4.2.2 ROM to the device and i ended up bricking it somehow. I looked around a lot on here and youtube. I found one solution i had not tried which was to get into recovery mod. But the device was stuck on the boot loaded. So i hard shut it down, and pressed the key combination to load the boot loader. And, the screen wasn't loading. I heard the little chimes my computer makes when ever a USB device is active, so i heard the thing load into the boot loader. But its not showing on the screen!
Please help i really shouldn't have done this. But i am literally about to cry.
I tried using Wugfresh's Nexus toolkit to flash the ROM, and it would stop on sending system.
I dont know if i did something wrong, if the kernel was messed up, if the kit wasnt right, please as the video said there is 4 million members here. someone has to know what to do...

That is not the bootloader. You need to have your device disconnected from your pc. Then go to your bootloader.

I feel kind of stupid.
Nope. Not working. And its not the battery. its plugged into the wall.
Just a noob guess, Is it possible the device isnt even using the display? Like its so messed up that its per say not even realizing it has a screen?
Try volume down and power. It is possible that the screens flex cable came loose. Pop the back off and check. You should be getting some visual queue. If all else fails hold the power button for awhile. Like around 15 to 20 seconds. I have had to do that a few times. That should fix it.

OKay. Whats the best tool i should use to get it open?
Also thank you so much for your help.
You can use a fingernail really. The best thing is a plastic spuger. A guitar pic works nicely. Just start at the bottom and work your way around.

Have you dropped the device at all or sat on it? If you are getting no visual queues, either you have a loos flex cable, or the lcd is cracked or just non functional all together. The best way to check that is to shine a flashlight at an angle into your screen. Look for any odd lines that have a slight or significant curve to them.

Assuming i found the right cable which was under a copper shielding that was running up from the metal frame under the battery. It was yellow.
It was tucked all the way in.
I didnt see any cracks or lines. I did sit on my pillow was under it.
That could possibly break the device. I just recently broke mine the other day in similar circumstances. The cable is right by the battery on the right. Should be almost centered by the batt.

Oh. But it was working the other day. Does it just do that?
and Yes i got the right cable. So what can i do now? It was rooted so i cant send it back, Is there anything i could do?
You technically could send it back... They can't confirm it is rooted unless you unlock the bootloader and the little lock thing shows up on the splash screen. And since your screen doesn't work, they can't see it unless they test the device after replacing the screen assuming they don't replace the whole unit. But I don't know their procedures. Most companies just replace the whole thing. The screen shouldn't just go out. Not saying it doesn't happen, but it shouldn't.

Alright. Ill call Google in the morning. I actually was following a guide i saw on a google forums thing where it said to flash the ROM if its not updating as it should. Which is what was happening.

Well good luck. Never thought one could fully brick a Nexus 7. From my understanding, it is damn near impossible. Tell them that you were updating to 4.2.2 and it won't boot up at all now. That should avoid them replacing the screen and checking everything ultimately getting you a whole new device. I know you said it's not the battery, but try charging it overnight and the try to boot it up. I have seen so many people think they bricked, but discovered later on down the line 'up to 6 months later' that their battery was just dead.

Touchscreen problem

HI!
My n4's screen doesn't recognize touch on the bottom of the screen. Everywhere working fine but the last 1,5 cm so I cant't use the virtual buttons. I send it to Telenor to repair but after 3 weeks they don't do it, because the simtray is oxidized, so i lost the warranty...
Of course it hasn't got any water...
Do you have any idea what should i do?
Thanks,
Kodam
Its a common problem, flash PA pie and live with it.

I tried that but sometimes it randomly recognize touch on the bottom of the screen and not working until i switch the screen off-on.
Are there any mod which can decrease the "size" of the screen? With this the random touches can be avoided.
Sry for my english
