[Q] Touchscreen Not Working, How to Reboot?

I installed the latest firmware update. The TF went into sleep mode and I was able to turn the screen back on, but not unlock it. I attempted to reboot but the touch screen is unresponsive so it is stuck on the confirmation screen.
I tried the data wipe, (power + volume down and then volume up) and it doesn't respond. Is there any other way I can force a reboot?

I did a forum search before posting this to see if my question had been asked and answered before. Nothing came up.
After doing a Google search, I saw this came up previously and found the answer in a previous thread on this board. I was able to force a reboot and it works fine which is great!

Hi
I have the same issue. How did you force the reboot ?
Cheers,
Xhulu.

It is either volume up and power or volume down and power. That will take you to a menu for wiping tablet data, you can press volume down to decline data wipe and it will just reboot tablet. Hope this helps.

To force a shutoff, hold the power button down for 10-12 seconds. Then after it shuts off, press the power button for a few seconds to boot it back up. No touch screen necessary.

Tried this, got device wiped but screen is still not responding.
Any other idea how to reset/restore screen sensitivity ?

I had the same problem.Tried for hours to get past the welcome language screen.
I had nearly a full charge but decided to plug in the charger....and the screen became responsive again

well i did that as well,many times, no luck!
i'm just gonna leave it charging until i fed up and try again, if no luck, this **** is going back!

Curious, how's your TF today?

left it to charge at least 10 hrs, even though it was around 90%, and it still no response!!!!
rebooted it and no luck at all!! Wiped data like 10 times!
i'm waiting for the battery to drain now, and we'll see if there is luck

Same thing happened to me. Asus wanted me to pay to ship it to their repair center so I just returned it and ordered a new one. Didn't cost me a dime...

Phone won't boot

Hey guys,
My phone shut off unexpectedly today and now won't turn back on. When I try to power it on I see the Google logo for a couple seconds and then it'll just shut off again. I tried holding the volume up/down buttons to access the bootloader, but right after I get to the screen it just restarts itself again.
Connecting to power (AC or USB) causes it to constantly reboot over and over, it just shows the Google logo for a couple seconds and then restarts again.
Any ideas on what I can do?

Provide more information for a starter - stock? unlocked bootloader? rooted? third party recovery? rom and if yes which?
If it's stock I'd RMA it.
If not what did you do immediately before the problem started?
try holding the power button for > 2 seconds which should turn it off completely, leave it on a wall charger for at least a couple of hours then turn it back on - I doubt it'll fix the problem but it's a simple thing to try...

Everything on it is stock, no ROM, not rooted. I had just taken it out of my pocket to check the time, put it back in my pocket and then felt it vibrate, took it back out to see it at the Google logo and haven't been able to get it started since. There was one or two times when it got past the Google logo and started to show the start up animation (the four colours bouncing around or whatever it is) but then it shut off again.
I tried holding the power button to completely turn it off, but plugging it into the wall charger just causes it to repeatedly attempt to boot like I mentioned earlier. I'll leave it for a while and hope for the best

Sounds like the mobo is bad. Most likely will have to rma it.

Maybe not. Sounds like a stuck power button to me.
OP does the phone just endlessly repeat this cycle? If so it's rebooting itself do to a stuck power button. One other users already reported similar issues and his power button was indeed stuck. Mash the power button hard for a minute to see if you can unstick it.

Thanks so much, really wasn't looking forward to waiting for weeks while the RMA went through. The button didn't appear to be stuck - it was still clicky - but after mashing it for a minute it started up normally and appears to be fine now.

Did you flash any ROMs or anything previously?

brother the issue is gone, as mentioned "sticky power button" was causing it. read the thread before posting. btw thanks for effort anyway... haha
:laugh::silly:

Hi all. Sorry to reopen an old thread (but xda suggested I check here before making my own thread).
I think we have the exact same problem with a Nexus 5. Unfortunately, bashing the power button doesn't seem to be helping (and makes me feel slightly silly .
Anyone know how much effort it would be to take it apart to get to the part that's stuck? Any good instructions?
Thanks.

Weird, I have the same issue starting a few hours ago. I updated to the Oct 17 beta of Cataclysm then a hour later it happened. But was told it sounds like the power button issue.
Took it apart, tried to fix it. If plugged in I can get into the bootloader, but then it reboots again. I've tried tapping it on a hard surface, and it gets seems like it almost fixes it because it'll connect to my laptop but then reboots again.
Could it be the battery? It was fully charged but then died as I was deleting hundreds of photo's in Dropbox to move photo's over from my phone because it was full.

I too am running into this same issue. My screen cracked so I replaced the digitizer with some success. In the process I damaged the battery and needed to replace it. When I got the new battery and replaced it my phone is now unusable.
When unplugged: I turn on the phone and it's running the ANDROID animation then turns off.
When plugged in: I turn on the phone, the ANDROID animation runs then the phone restarts and continues the process over and over again.
I then flashed the phone with Marshmallow and the same thing happens. Except now that I flashed it I get the Android icon with the spinning gear. So; I flashed it back to 5.1.1, but the same result.
Could I have physically damaged something inside or is it a battery issue? Thanks for any insight.

[Q] Nexus 5 constantlly turning on and off

For quite a long time I did not make any change on Nexus ROM or applications, but yesterday my Nexus turns off while I was web browsing. I tried to turn it on but it refuses. It is only possible with USB cable plugged in, but then it constantly turns on for 1 second and then turns off, and this is going in endless loop as soon as USB cable is plugged in. But with unplugged cable NEXUS can not be powered on.
The video can be seen on this link
https://www.dropbox.com/s/cvyxii4ctm4aqgu/VID_20141110_190522.mp4?dl=0
Yesterday I somehow manage to get in recovery mode and I wipe cache and Nexus boot ROM, but after 30 minutes of usage it again turns of by itself. After that for more than 100 times I tried to get to recovery mode but I could not.
So, I think that my only chance to wipe cache and put new ROM is through ADB. But I do know how to do that. Can anyone help me?
P.S. I both my NEXUS in US, but I live in Croatia (EU) and Google tells that they can not make exchange for other NEXUS (although my phone is under warranty) because they can only do that for postal address inside US. Because I do not live there and any of my friends or relative will travel in US soon my only way to get my NEXUS working is through ADB.

sounds as your power button is "stuck'.

Shake your phone vigorously for a minute, I've been using that as a temp fix for a dodgy power button exactly as you've described

It usually helps the button back out again, I think you should RMA to LG, I'm sure they're worldwide. You could always open up the phone and try unsticking the power button if you can't be bothered sending it back.

Power button is not what cause the problem. I found many reports about the same problem, like on this page
http://www.reddit.com/r/Nexus5/comments/29tr5n/nexus_5_wont_turn_on_google_screen_keeps_flashing/
but nothing which I tried did not helped. But certainly power button is not causing the problem.
When the problem appears for the first time I manage to get into recovery and wipe cache, and after that phone booted ROM. After 30 minutes of working phone turns off and now I'm not able to get even into recovery.

and im rooted with the latest build from pac-man (a clean install), cant even get into the fast boot and recovery to recover to stock since its doing this bootloop thing
any more help would be amazing

So, since shaking, hard wacks, and anyting physical did not helped after your post I dismantle my phone and without back plate and upper plate on chips my phone works perfectly. So it seems that upper plate which covers chips is the cause of the problem.

For me, not even disassembling has helped, so I bought another motherboard and put it into my phone.

the problem occured and i found what it was my power button it wasnt staying in place like its tilting so now i got to buy a new button for it :/

As far as I remember, the button is soldered to the board, and can not be bought separately. I know the second thing for sure, since I was also only searching for a separate button in the beginning...

blocked on black screen

Hello,
Ive tried to look for a similar situation in other thread but each case is different so i open a new one.
This morning, when i took my idol 3 the screen did not switch off when pressing power button. I thought it was battery but when i plugged charger,nothing happened except the led is on continuously. I kept power button pressed for 10 seconds. The phone vibrates shortly but still a black screen, no sound and no reaction from the touch panel. Power+vol+ did not led me to my twrp recovery. What can i do now to get it work again? The phone is rooted with Rom Eu 4.2 from murigny64 and it is the first time i encounter this issu. Thanks in advance for helping me

Tonight i disconnected the battery for about 30min then connect it again. Then i tried to start in recovery: Just a vibration but no display and no sound. I unplugged/plugged the battery again and try to start. Same problem. What the hell could happen? Maybe a deffective hardware

Insist on boot ( normal or in to recovery with vol + and power).
That is a hardware brick.
Happened to me to some times, insist, it will unbrick

Hopelessly i tried to restart several times before you post your message. But im gonna try again.
I charged the phone all the night but nothing better and the phone is not detected on pc so no adb action possible.
Maybe the battery is dead...

Can be, can be to... To bad if is battery.
But still trying to boot, is very difficult to.
.

thank you for advise but it's still not working. I spend about 30 minutes trying different combination of button: power pressed until it vibrate, power+vol up, power+vol down, power+vol up & down, discontinuous press of power with charger and no charger....and so on. Its a complete failure.
If it is the battery, there was no sign of weakness before (short life, random shutoff, ....) . It happen suddenly: I lock my screen before sleeping and the next morning no way to switch it on again.
I thought I would avoid problems for long with a twrp recovery, a backup and adb tools on my pc.....but for hardware issues its useless.

How can I be sure it is battery before purchasing another one ?

If it was the screen the touch panel would work and i could sense vibration when typing the pin code no?
The led bright continuously when i plug instead of flashing slowly as it used to do when charging. That why i think its battery.

...and when i start in recovery the phone is not detected on my pc

That's hardware brick. Don't give up, try to boot, normally or in recovery, keep trying it will boot.

Have you tried to open the phone and disconnect battery? Custom ROMs made me similar issue a few times.

Therefore the back can be dismantle and we can access battery and that s what i did.
Yes i disconnected it for several hours and pluged it again but it gave me the same result. And now it doesnt vibrate anymore when i keep the power button pressed a while.
I purchased a battery on internet and im waiting for delivery to test if im right or not. Il feedback about the test.
Anyway its nice from you to look for any solution. Thanks

I guess you did everything properly, so just one thing: at first time when I did this, I choosed the wrong cable (which didn't 'reset' the phone), so I hope you pulled both out.

Hello,
I received the new battery today.
So i unpacked it, i unplugged the old one and plugged the new one ...and guess what happened......the same bevahiour as with the old battery: when i press the button power, it vibrate but it doesnt start neither in recovery nor in normal mode.
I just precise that the new battery is charged at 50%........:crying:
So the problem is not the battery but it was the only thing i could test by myself before sending the phone to alcatel for repair.
Im still wondering what could happen to my idol 3: It had been woking perfectly for months and one morning with no warning, it refuse to switch on. Ok sorry for annoying us and hope it wont happen with yours.
I hope alacatel will apply the guarantee although the phone is rooted and bootloader unlocked....because its a hardware issue i think.

Hello,
Just to conclude. The phone got back from repair after 10 days. They have changed motherboard, battery and also the back that was damaged. Its a brand new phone .

TWRP seemingly bricked my pixel

So I was trying to make a backup with the latest twrp and I got this error code: createTarFork() process ended with ERROR=255.
I figured, to hell with it I'll reboot. Twrp asked if I wanted to install the twrp app, I said no. Screen goes back, never to turn on again. No button combo holding for any length of time helps. Bummer, right? I was running DU at the time.
Now I'm worried about the RMA, I hope they don't deny me after they get it back into the warehouse.

Does anything happen when you plug the phone into the wall or into the PC?
Have you tried just holding down power for a while?

are you on beta hardware. i noticed today my phone was unresponsive installing twrp it would go black and disconnect from pc. what i had to do to get it to turn back on since it stayed lik that even holding the power button for a while was just hold the volume key and power for a couple min down and power if that dont work try volume up and power just random pushes to get the phone it will go to some debugging screen then just holding buttons till it restarts

I've tried every button combo. Plugged it in to wall overnight and computer. No response. Makes me paranoid about twrp for pixel because I was rebooting from there, but then again it doesn't seem to be a big problem in the community

I also had the same situation go on as well. I'm not sure what's is happening but when I boot TWRP the thing just becomes unresponsive and a black screen. I had to hold the buttons for nearly 30 seconds before it worked. Pixel isn't a friendly device to mod. :-/

Yes I was using twrp, I was flashing test build. But it put me into a loop. U got a black screen, and if your computer won't even recognize it , you may be out of luck. I have been using rc2 I know it's not great for restoring backups, but it works good for everything else

That is so strange. I have never come across this issue before. Unfortunately, if you can't seem to get your PC to recognize the device, I don't think there's anything you can do. I guess we will have to be wary about using TWRP. I haven't had any weird issues myself with TWRP but I know others have. Here's hoping google will honor your warranty. I think they will, I don't think see them spending the time to look into what caused your phone to die so I think you'll be able to get a replacement without much hassle.
If you wouldn't mind, please keep us updated.

So far so good, sent then phone in and sold the replacement. I'm getting the OnePlus 3t instead.
