Sleep of Death?

Phone is currently stuck in this state. Pretty much doesn't respond to anything.
Tried hard resting, connecting it to the charger, connecting it to my laptop and those methods didnt work. I have an insurance replacement coming, but I would like to recoup the money I put down as the deductible for the new phone. Anything else I could try to get it working again?
This was my only fear about buying a phone with a non removable battery.
Thanks.

Non-removable battery has nothing to do with it. Holding the power button for about 5 seconds is the same as a battery pull, and its hard coded to work in just about any situation. If this doesn't work, a battery pull wouldn't either.
Did you try to get into bootloader? Try running the RUU?
Did you do anything to get to this state (flashing ROM, other mods?), or did it just happen randomly on its own? Is the phone stock or not?

If you can't go into bootloader or recovery, you might try what this guy did:

Phone was rooted.
Tried to get into bootloader and that didn't work either.
What got it into how it is was me just turning the screen off.

Oh wait, you were complaining about the non-removable battery, in the event its just a bad battery? That's possible.
But can also be some other hardware failure, or software.

Interesting. I would copy that in notepad and save as a batch file, correct?
Edit: That probably won't work as the phone is recognized by the computer. Something must have failed in it or something.

This has happened to me twice since I've owned it. Thing is fine, charged, no problems. Then I go to wake it up and it just won't turn on. I pressed the buttons for a while in no particular sequence I can recall, but it came on eventually. Maybe holding down the power and vol-down buttons for like 10 seconds. Also, never tried calling the phone when it was in that state. Would be interesting to see those results.

Been trying trying that to no avail. I guess I'll keep trying.

Leave it on the wall charger overnight. Wall charger charges faster than USB, so use the wall charger. I've seen some phones (other XDA users) come back from a state like this, after charging for several hours.

Any luck?
FYI, mine did this AGAIN two days ago at about 10am. Then later that afternoon, it rebooted for no reason. And that evening at about 7:30, it rebooted again but this time never made it past the HTC splash animation. I suspect it had something to do with one of the Wi-Fi penetration apps I installed last week - because it had been acting a little squirrelly ever since.
Fortunately I had a full backup from a few days prior. Booted TWRP recovery, wiped the caches and system, restored that backup and my phone's been smooth ever since.

[Q] Nexus 5 constantly rebooting at 'Google'

Guys my gf's Nexus 5 shutdown today and just refuses to boot up. It doesn't do anything with any of the keys pressed in any of the combinations that are defined. But once it is plugged in to the charger or USB, the google logo pops up and the phone keeps on rebooting to that logo. If the volume down key is pressed when this is happening, the fastboot mode is visible for a second and the phone keeps rebooting. No action can be done in the fastboot mode due to the quick reboot. I am attaching the video of the problem. Any help guys?

What if you boot it pressing vol up + vol down + power?

If on battery, then the phone does nothing. If plugged in to charger and the key combination is tried then the phone keeps on doing as shown in the video.

Don't know what's going on.
Try doing that but with the phone connected to a PC that has adb and fastboot installed.

I would leave the phone plugged in for an hour and don't touch it. Then try.

You have a fauilty or a stucked power key.
If it is just stucked then you can unstuck it by abusing the power key or taking the phone apart.
If it is fauilty then you have to claim your warranty.
If you disassemble the phone you will void your warranty

A few days back, she had got the power button fixed because the power button response had become intermittent and the phone was rebooting randomly. She had taken the phone to a LG service center first, but they told her that changing the button or trying to fix it might damage the board and told her to change the board altogether. So we took it to a local repair guy who fixed it and the phone was working fine till yesterday when it shutdown all of a sudden and then the rest is history.
Note: The phone is not under warranty as the phone was bought from Dubai and we stay in India. No international warranty.

Then you have to visit that local repairer guy pay him to replace the power key again or pay LG to replace the mother board.

Yeah the repair guy you dealt with must have fixed the button short-term but in doing so inadvertently caused it to short out. Meaning it needs to go back to a repair shop (better one) and cross your fingers that it didn't short out more important components

Okie. Will take the phone to LG tomorrow or over the weekend.
Guys please clear my one doubt. If it's the stuck power button, what does it have to do with the phone not doing anything when on battery but decides to go till 'Google' when plugged in?

Did you get it fixed? I have the same issue and I've tried many ways to bring it back to life. My last step will be taking it to the tech support, because I live in Brazil, and I'm pretty sure they will charge me expensively as hell.

Had my Nexus 5 for about a few month now, and have loved it till this morning, it decided to just shut off (full battery too) and i tried to turn it on and it is now just constantly starting up to the "Google" splash screen then shutting off.
Sometimes it gets to the the 4 color circles then shuts off.
I want to enter into recovery mode, but I have no time to click recovery mode as it reboots frequently
One thing i noticed when it did boot up was the power button seems to be extremely sensitive and volatile

I had this same problem.. It constantly rebooted and wouldn't let me get into recovery.. Every time I plugged in the charger it would reboot also. You have to let the battery completely drain.. I gave it a couple weeks.. then tried it again and it worked.

Found a solution
Well same thing started to happening with me yesterday after installing android L's developers' preview in my nexus 5. It worked well for first 4-5 hours but then after terminating a phone call when I put it back to my pocket problem started. I searched many forums for solution then I decided to re-install from image. I connected my phone to My PC (Which had driver installed & fastBoot setup) dramatically my phone started working well. And I detached my phone from PC. So I thought it might solved because after supplying charging. But after 3-4 hours it started again so I directly plugged in to electric socket but it kept on rebooting. Then I turned on my PC and attached my nexus 5 with it. Again it started dramatically.
Still I don't know the exact reason behind it. But good new is my phone is still working since last 16 hours... But I took care of not to launch some apps listed risky for developer's preview. So I thing some incompatible app launch may be a reason... but still its only "may be"

If it happens again try what I just answered and let us know if it worked for you? So we can come to know if solution was nexus 5 specific or android L specific. Also mention the OS version, please.

[Q] [Help] Stuck at Google screen

So, today my Nexus 5 crashed while using it normally. It is not the first time, of course, but these specific problem appeared just one time before now. The phone is dead, but just until I connect it to the charger. Then it begins to show the Google screen at the beginning, crashes, and does the same thing again. The time between the crashed variates from 1 to 5 seconds. I also tried to get to the bootloader, it works, but after 1 to 3 seconds it crashes again and goes back to the Google screen, crashing, Google screen, crashing,.... Disconnecting just causes the Nexus to turn off completely, and instantly.
Custom recovery: MultiRom edition of TWRP
OS: CM11S V.1.5
Kernel: big-bum V.28
I googled, but all the people having this problem were able to get into the bootloader without crashing and also their phone turned on without connecting to the charger.
Maybe you guys have an idea what to do?

Might be a faulty power button which got stuck in and is causing reboots. In most cases its this.

This could be right. But why does it only try to boot when it is connected to the charger?

Cause the battery is dead.

It Had about 50% when crashing and I connected it 2 hours to the charger trying to reboot, so this would be very strange.

Strange maybe, but probably the case. All those reboots will drop a battery quick.

But how can I charge it. It starts directly with the booting

Leave it for several hours.... Hopefully it charges faster than it drains.
But it's irrelevant if it's the power button. That needs to be addressed. Trying to flash anything is risky if it's gonna reboot on its own.

Yeah, but how can I check if it's really the power button? And, the worst thing, I can't even ask Google for an exchange because of a crack in the screen.

Go into bootloader mode and see if it reboots. If it does, it's the button. If not... See if its OK a while sitting in that mode. If so, flash stock with fastboot.
That's all I can think to try.
---------- Post added at 05:28 PM ---------- Previous post was at 05:27 PM ----------
Oops, You've done that.
So it's power button.... Or some sort of power short otherwise. But button is the best bet.

Thank you for the help. I will try to fix the button.

[Q] Bootloader bootloop problem

For a few days, my phone kept rebooting on and off. I thought maybe it was an unstable ROM or Kernel, and it was driving me crazy. No matter what ROM and Kernel I tried it kept doing it. I even restored the factory image to completely wipe everything on the phone and it still did it. Then less than a day later my phone just kept rebooting at the bootloader. I can't get it to the recovery or anything. I thought maybe it was a messed up power button, so I took it apart, removed the power button, put it back together and then tried to power it on with the button removed and it still reboots at the bootloader. How do I fix this? does it mean I have a bad motherboard?

It means your power button has problems (still after reassembly) or you have a motherboard issue.
Send it in for repair.

It does still sound like a bad power button. And if it keeps rebooting, you can't even try flashing stock. Tho, it's not software by the sounds of it.
Maybe take it to a repair center. Shouldn't be too much to fix.

I can tap the back of the phone a few times and it just reboots. A couple seconds into the boot animation, it shuts off.

Bad power button or battery connection may be lose and power is cutting in and out.

Battery issue (battery indication level stuck at 20%)

After a shut down due to low battery, I powered up my Xperia Z5 while charging it and the battery has been stuck at 20% every since. I tried doing a factory reset and also letting the battery discharge until it power offs and charge until the battery seems full (roughly 2 hours for quick charge), but the battery level is still stuck at 20% not even budging at all. I removed the battery icon from the status bar and re-added it but it still remains as 20% (when I press battery usage I would only see a horizontal line at the 20% mark). My phone is not rooted, what should I do that might work..? I purchased my phone from Taiwan and I'm currently in the states so requesting for an RMA would be a pain.:crying::crying:

Press volume up or down(can't remember which one) together with the power button till the phone give 3 vibration.

Think you have bad battery and need replacement. Hope I'm wrong.
You can try to go into service menu there is something about charging try it.
It is Factory charging.

HI. i'm having the same problem and searching for the answer. hope you'll update battery issue. tnx.

Try to do simulated battery pull.. Turn off your phone then press volume - and power button and count to 20 then release and start up your phone.

I read some instructions regarding this last year and it helped. I forgot where did I search it. Just open the port where sim card and sd card is, then press the yellow tiny button inside simultaneously with the power button until it vibrates for sometime until it ends. It didn't work for just one time, you'll have to do it over and over again until its fixed. The next day, I tried it again and voilà! Battery level tells the truth again! I'll try to find who gave this instruction for you to have the full details, and also to thank him.

You have to delete "/data/system/batterystats.bin" file, WHEN your charge 100%.
Shutdown your phone charge until 100%, then follow one way..
Two possible way to delete this file.
1-)Rooted Device (with file manager like Root Explorer)
2-)Flashing stock FTF with select all WIPE options on Flashtool.

Case solved! Full instructions...

Okay, here it is, the full instruction.
*It will take several attempts but be patient. Hold down the red/yellow button (whatever the color is, I can't see it clearly with my xperia z5 because I previously used a ball pen with it and it tainted mine) inside the sd slot and hold down the power button at the same time. When it hits the last vibration (1 buzz then some buzzes=1) do this until it vibrate three times then plug the charger. Leave it within 5 mins, and if it has not done anything different, repeat.
I got this instruction (*with some minor edits) directly from a member in another site (talk.sonymobile.com). The name is "metalfacemegan". Well, there you go! Goodluck!

It didn't reset mine and yes I used that before, like several times when I was fixing the battery issue. As far as I know, all the data of my phone were not deleted including the internal storage. All is good for me.

Maybe you should back up first your data on the internal memory just to be sure. When I did it to mine, all apps, messages, logs, calls, and etc. were fine.
