My N5 looks dead, but.. - Nexus 5 Q&A, Help & Troubleshooting

I dont think my Nexus 5 died because the last I saw it still had above 20% to 30 %, but it did just turn off on me and now it will not turn back on. I tried holding down the volume up+volume down+power button for more than 10 seconds and nothing. also tried vol+ + Power and vol- + power. Here's where it start to get werid. I tried to plug it into my PC, but it doesn't recognize it. It's just trying to install the "QHSUSB_BULK" driver (and fail). Also when I place my phone on the charger, nothing happens. I know you cannot take the battery out which really annoys me. After few hours, I tried just turn on with power button and voila, it worked. but i don't know why. it happens randomly. i am root user and tried different roms but still happening. any ideas?

Your battery seems to be near limit of it's age. Try calibrating battery..

Phone entirely bricked. Won't turn on, won't charge, nothing.

I was taking a video, and finished it, when suddenly the phone froze up and turned off. I've been using MIUI, and while it's mostly pretty stable, reboots and crashes happen, so I just rolled my eyes. But since then it's been completely dead. I couldn't turn it on, even after taking the battery out several times, can't put it into recovery or download modes, and it's been connected to the charger for about ten minutes now and still nothing.
I haven't flashed anything for ages, haven't done anything odd with the phone at all, I have no idea what could have provoked this. Please help, I can't imagine what I'd do if my phone was permanently dead.
Samsung Galaxy SII with MIUI weekly ROM (currently 2.4.27)
Things I have tried:
Long press power button to turn it on (obviously)
Same thing after taking the battery out for ages
Press Vol up + Home + Power to put it into recovery
Press Vol down + Home + Power to put it into download
Plug it into charge
Plug in data cable connected to computer
Take out battery for a while, then replace, plug data cable into computer (but not phone), hold volume buttons while plugging in phone (internet guy told me to)
Everything above shows absolutely nothing on screen. Charging heats it up a little.

[Q] HTC one S wont start, no blinking, no led

Hi guys !
My HTC One S died yesterday just before going to bed.
It was 10% battery, I used it for 10-15mn and it went down to 3% and then 1% and shut down just before I plug it to the wall charger.
I let it there for 5mn and tried to power it on but nothing happened. I noticed that the charging led was not even working.
I let it overnight charging and this morning, still nothing. I tried to enter bootloader with power+volume down, nothing happen
This morning, I tried :
- 2 hours usb charging, not detected by the computer, no led, won't start even in bootloader
- 2 hours wall charger charging. Still no led, won't start
Any idea on what to try ?

Ok, simulated battery pull.
hold the phone under bright light (sensor see's the light and allows to power on, something about a feature to prevent resetting while the phone is in your pocket). press power button, press and hold power button if that doesn't work.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Maybe it is locked up, and really has been charging. Press and hold power button for 10 seconds.
Some have had success pulling the sim card, and then pressing the power button. Then when it turns on reinserting sim card.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Factory Reset option: would erase phone storage though.
If you can’t turn HTC One S on or access settings, you can still perform a factory reset by using the hardware buttons on HTC One S.
Press and hold the VOLUME DOWN button, and then press and hold the POWER button.
Wait for the screen with the three Android images to appear, and then release the POWER and VOLUME DOWN buttons.
Press VOLUME DOWN to select FACTORY RESET, and then press the POWER button.

Others have switched to trying to charge it connected to USB port and have it suddenly come back to life after a while.
Thanks for the answer

Will try this one !
In fact it really looks like it's dead : no led, nothing happen when I let it charge (it's not even hot) and nothing happen when I push all the possible buttons combinations :crying:
Read my post. Try to do with linux first.

Please help me! my nexus 5 is dead!!!

Please I need help, I was using whatapp when my nexus 5 froze. Then I hold the power button and the phone restarted normaly, but when it was showing the google logo it froze again turn off and now It does't respond to anything. I alreadu tried with hoding the power button or holding Volume up+Volume down+power and it didn't respond. Please help me!!I forgot to say that the phone was almost fully charged and wen I connect the phone to my notebook, windows doesn't recognizes the device.
Hold down power button for more than 30 seconds and see whether it boots up?? If not, hold down volume down button+power button together for 15+ seconds and see whether the phones goes to bootloader?
If above things fail, connect it to a wall charger and leave it for an hour or so and try to boot it up. If you still cant, it's probably a hardware failure and it needs repair.

It seems that is a hardware fail then, because I follow those instruction several times, and nothing happens. The phone remains dead.
When you connect it to a wall charger, the front LED become red ?

[Q] xperia z3 not respondig

hello,
I had left my phone to charge at night, then this morning it was not responding. Power button was not waking up the phone. Then i forced to reset by power and volume buttons. Vibrated 3 times and completely shut off. Now it is not opening.
I already tried, reset button in sim cards slot. It is not working also. Please help me.
Did you try connecting it to PC Suite or FLashtool? Check that once and also try charging another hour and then force reset the phone. Also I think there is a reset button somewhere under the sim card slot. Try that one too.
Hold volume up and press power. Wait for beep three times. Give it a few seconds and then press power alone, should boot.
Thanks guys, i tried both but still i have sudden death. reset button and power+volume buttons not working. Also flashtool could'nt find my device.
Thats not good, any led when plugged in?
I had a similar instance after flashing unofficial cm12. Phone was cooling down from taking a run through an obvious cpu bug that really killed my battery. I shut it off to cool down with 20 precent still left in the battery. And the phone started to act this way when I went to power it on. No led power indicator or anything even with usb connected. My computer did respond to the usb being connected as if a device was there though. I waited about 10 minutes with the phone in front of some cool air and then did the volume up power button reset which worked then. Still quite a scary incident.

Powered off, no charge light or power on

Hey all, I searched around, just haven't found the answer I'm looking for.
First, I did get it to bootup after holding Power+vol up/down, and I'm trying to understand what happened.
Running stock Verizon 4.4.2
Bootloader unlocked, S-off
Rooted
The phone was at about 75% charge and I was viewing gallery. I noticed that videos were no longer playing and was trying to get one up. The phone suddenly went black as if it powered off. I pushed the power button- nothing. Held the power button - nothing. Did that a couple more times for longer.
Then hooked it to charge - no light, nothing.
After a quick search I found a suggestion to hold power+vol up/down 1-2 minutes. I did that and it booted in about 15 seconds.
My question is, what happened? why?
Is there a way to avoid it?
And if it does it again what is the best way to get it restarted?
I still plan on flashing a newer ROM, just haven't done it yet.
Thanks
Really, no thoughts on this? Phone goes blank, won't restart. Someone on XDA must at least seen it.
Happened to me once but due to my own mistake.
I wanted to boot phone into bootloader, instead of shutting and then pressing vol down + power, i forced shut the phone by pressing power + vol up, here is where i commited the mistake, instead of holding the buttons for 7 secs( after which the phone should go off) i held them a bit longer mayb 15-20 sec, after tht i tried to boot into bootloader by pressing v up + power , nothing happened, did that several times, again nothing. Tried to power it on, nothing, connected to usb, again nothing.
It seemed like i had hard bricked the phone(thoughts of losing the phone came to my mind) but after trying and trying and trying again and again. It did got up(i held vol up + power for 7-10 sec, without releasing the power button, and releasing the vol up button, instantly held vol down button and it booted to bootloader).
Mayb the phone enters into some other kind of mode which only HTC is aware of.
Thanks piyushkohli97 for the reply.
Hasn't any developers run into this? Or someone with an understanding of the issue? It doesn't seem uncommon. I'm hoping to gain some insight into the issue. Anyone else?
