Power Cycling - Sprint Samsung Galaxy S7 Questions & Answers

So my new Galaxy S7 is power-cycling in to recovery mode but the boot won't complete. The battery is completely dead and while charging it continuously tries to power on in to recovery mode. I can't get it to do anything else. Buttons aren't jammed. Any ideas? I've scoured Google but nothing has come up so I figured I'd rely on Good ol'e XDA!

Sounds like a hardware failure. That's what warranties are for. Take it back to Sprint for a replacement.

Tried that. Didn't work. I opened the sucker and found out it was a motherboard problem. Thing heats up the moment the battery is reconnected. ****ing POS Samsung.

stuck on google trying to unlock

Tried to oem unlock my nexus 7 but pressed the power but to go to recovery mode. Tried different methods of turning it off, hold power, hold power + vol up/down, hold vol up & down with no luck. Now im wondering if i just need to let the battery die or something im not doing right.
If you hold POWER for 10+ seconds it will turn off. Then hold POWER, VOL UP/DOWN and it will load into bootloader. Hasn't failed me once even after F'ing up some ROM installs (for fun as tests). I've always been able to get back and fix myself.

ive held the power button for minutes with no luck...thought holding the power + vol down would work like on my one x but not luck either.
Remove the microUSB connector, wait 30 seconds, and then try again.
What screen are you actually stuck on?

so while trying to oem unlock i accidentally pressed the power button on recovery, so currently im on the white google with black screen page. am i suppose to reconnect to the usb after the 30 seconds?
Doesn't matter. Just leave the cable unplugged and then try boot up into fastboot mode again. There's no reason it shouldn't make it there.
UNLESS... you interrupted the OEM Unlock half way through. Maybe it screwed up your boot.img or something. Still, I would suspect you can get around that and back into bootloader.

thats the thing i cant get out of this google page, im trying to find out if theres anything other method i havent tried
Sorry mate. I've never had a problem power cycling a nexus device even after royally F'ing it up on purpose. Maybe just let the device sit there all alone for a bit, unplugged, and then try again in 15 minutes.
Best of luck.
problem solved-fixed with battery pull

Major issue with my N7

Ok everyone I am having a major problem with my N7. This morning I noticed it was out of power so plugged i tin like normal, then I went to turn it on got the Google logo then it went to the Nexus logo. And it kept cycling through the nexus logo for hours and will not turn off. Whenever I try to turn it off it just restarts from the beginning. Now I didn't buy my tablet from the play store so I would have to go through Asus for a warranty replacement. Has this happened to anyone else in the past?
Some info. Stock, unrooted, locked bootloader, stock 4.2
Well this never happened to me before. Did you try removing the battery?
Well, to start, unplug your N7 from the power source and hold the power button down for about 15 seconds, this should force it off. From there, turn it back on and let us know what happens.

I don't see that you have tried holding down the power and the volume down. This should get you a hard reset.
Here is a short topic where a power and vol down worked for someone where a straight power down did not:
http://rootzwiki.com/topic/30101-reboot-tip/
it's the last post (#6)
Rather than trying to run the battery down, which is not all the way down when it shuts off and would take a long time to discharge just sitting there, you could pull the battery if you feel comfortable opening the case. It's not glued or anything and the battery has a ribbon connector.
So its in a boot loop? Reflash the image with Mskips toolkit option 9 after booting into fast boot mode. If that isn't the problem then do a warranty return. Not sure why you're stuck in a loop.

[Q] Sprint Galaxy S5 Not Powering On

Can someone please give me some advice on what to do. My phone is less than 3 months old and will not power on. It doesn't do anything, not even the vibration it usually does. I've tried plugging it into the charger but it doesn't even have the charging light on. It was working fine and just stopped. I pulled the battery out and put it back in but nothing it working. If If anyone has any suggestions, I would be very grateful! Thanks!!!
what were you doing at the time
What were you doing at the time the phone stopped working? Did you try charging the battery on an external charger?
As the poster above suggested, what were you doing recently? We are looking for clues as to what happened? Did you yank on the power cord, drop the phone, et cetera?
Make sure that your battery isn't in backwards in the phone and try using a different cable to charge the phone. If it still doesn't charge, then borrow a friends external charger.. or even the (charged) battery out of their S5 for a few seconds to see if your phone will turn on. We're trying to differentiate between a dead battery and all other problems.
If you still have no luck, then remove the battery for ten seconds, then replace (the presumably charged) battery in your phone. Then press and hold the volume down key. Then also press and hold the home key, then the power key. After about five seconds, you should see the phone start to the "download screen". If so, post here for further guidance.
If you phone is non responsive to a borrowed battery and the download mode described above, then you should seek warranty service with your carrier. A three month old phone should still be under warranty.

I was talking on it and hung up. Then, I tried to use it about 5 mins later and it wouldnt turn back on. What do you mean by "external charger"?? Sry, I'm not very tech savy lol! The only charger I have is the one that came with my phone. Thank you for replying! ☺

My battery was charged in the 70% and I also used my husbands battery (we have the same phone) but that didnt work either. I'm going to try your other suggestion. Thanks!

Can you get into recovery ( volume up + menu +power button) or download mode (volume down + menu + power button)?
You may read this article http://www.technobezz.com/samsung-galaxy-s5-not-charging/, hope it helps.
I tried the volume down + home + power and it didn't work. I'm not sure what to do. I don't want to make a trip to the store but it's looking like I'm going to have to.

It may well be an electrical hardware issue, it doesn`t look like a software problem to me. Good luck and i hope its fixed soon

It is looking like a hardware issue. If you are positive that the battery is charged.. i.e. if the battery turns your husband's phone on, then we ask what is different about your phone? Most software issues would be bypassed by starting a phone in download mode, which is why I asked you to try that.
Have a quick look at the battery "fingers" or pins on your phone. Those are the gold or silver coloured pins that line up with the gold or silver tabs on the end of your battery. Do they all appear to be the same? There isn't one that is bent out of alignment or shorter than the others where it might not be making contact with the battery?
And why not try one more test? See if the phone will start up in "recovery mode" this time.
Pull the battery out of the phone for ten seconds. Then replace it. Now in order.. press and hold the volume up button, then press and hold the home button as well. And last, press and hold the power button. Continue holding all three for ten seconds or until you see the phone screen turn on.
If that still doesn't work, my best guess is that you may have accidentally banged and damaged the power button. If it was me.. I'd try pressing really hard and wiggling the power button for a few seconds to see if you can cajole the phone to power on at least once and confirm the problem.
But that is about all that we can do. If you can't get the phone to power up with a known good battery.. then th store needs to check it with test equipment to narrow down what the hardware fault is.

Stock brick?

Hi there!
Not sure if anybody has had this issue, or if this is new (hopefully not, and hopefully there is a known fix).
Everything is stock, no root. Device was around 90% charge and powered off completely. Tried to turn it on, nothing. Plugged into charger - nothing. Tried to access bootloader (power + down volume) - nothing!
Any idea if there is a way to recover at this point? Google is already overnighting a replacement device, but I'd like to retrieve some data.
Thanks!

Keep it on the charger, keep trying the power button to turn on (make sure it clicks then hold it a long time), same with power+vol. down. At least you are getting a replacement.
did you try to press and hold the power button for 15-30secs ?

Left it on the charger for about 4 hours then booted into the loader and started fine... I did try holding the power and volume for 45 seconds previously.
Not sure if I should take the new phone or keep this, not sure if they're sending a refurbished. But don't really want to deal with restoring data... Thoughts?

It depends on how long you've had the original phone. If you contact Google for a replacement within 15 days of purchase you get a new device, any longer and it's a refurbished unit.

Broken power button and vol-down, options?

A friend of mine has just let me know the power button of her Galaxy A40 is dead. The volume down was already dead so before I provide any advice I'd like to hear from the device owners here. I have zero experience with Sammy myself.
I've already suggested Volume Styles to control volume on screen and Quick Settings to plant a handy shortcut to the power menu in QS. Other tips are most welcome! I've got two specific questions:
When this device is off and plugging in the charger, does the system boot or does it just go to a charging animation?
When this device is off and the volume-up key is pressed while plugging in the charger, does it go to fastboot?
Thanks for reading!
Powered off, charger attached, it charges no boot.
She will need to replace the power button. They all are probably one assembly.

Oh no no no, if that happens then the one that will be replacing that power button will be ME and we don't want that to happen. If she can get to fastboot, she can boot the damn thing on her own
Currently there's no problem though, I'm just wondering what happens if the battery dies or she accidentally shuts it off.

As far as I know the power button is the only way to power it up.
Lol, you knew the job was dangerous when you took it
Watch some vids, it may not be as bad as you think. Sooner or later it's gonna happen...
There's no harm in getting a quote from a local repair shop (hopefully there's a few options for you!). I had someone replace the speaker after it broke for £15/~$17 total.
