Device will not power on, no led lights, cannot get into recovery, etc. - Galaxy S6 Q&A, Help & Troubleshooting

Hi All,
I am having a bit of trouble with my Galaxy S6 device. I am unsure if this was the cause of my issue, though yesterday I had dropped my phone from a short distance. When I had picked my phone back up it was powered off and would not turn back on. This is not the first time my device has powered down from a fall, and this is not the first time I had difficulty rebooting my device.
My phone does not appear to be responsive to any attempts, nor does it indicate by LED that it is charging. When I dropped the device, I was just then taking it off the charger as the battery was at full/near full.
I have tried holding the power button, holding the power button and volume buttons, holding the power button and each of the volume buttons on their own, as well as holding the power button, volume down button, and the home button. I have not had any luck with any of these solutions, nor was the device responsive to any of these solutions.
When I plug the phone into its charger, the power brick does appear to be warm, though this may just be wishful thinking on my part. I have tried the power brick that came with the device as well as a third party power brick.
At this point I am going to try to get into recovery via ABD, but I am not confident that my device will even be recognized by my computer.
Many of my online accounts have an authenticator from my phone tied to them, I am desperate to get access to this again. Is there anything else that I have failed to try?
Many Thanks.
EDIT: I would also like to make note that I have taken very good care of my device and that there is no outward physical damage to the device. With this being said, is it possible that the drop could have rendered an issue with the internal components? Perhaps my device was still on and the screen just went out on me? Though would this also render the LED indicator inoperable as well? Perhaps the battery was jostled loose? Though in such as tightly packed unit, would this even be possible?

Verizon GS3 sch-i535 Serious Odin Problems, Please Help

Hello, I am in need of some dire assistance. I purchased a Verizon Galaxy S3, the phone itself works fine, but it does some kinda funky stuff from time to time. Like if I push the power button, and I unlock the screen, sometimes the screen will turn black and I have to turn it on again, then I fight it a few time to finally unlock the phone. Something similar happens when trying to shut the screen off manually. If I use the button the screen will turn off for a second then turn back on. I fight it but I normally end up just letting the screen time itself out.
I was hoping to root it and try a custom rom, hoping the issues were stemming from a crappy verizon rom. I downloaded all the drivers and the Odin files. I am very familiar with Odin and rooting, I have approximately 12 android devices rooted at the moment most of them samsung, some lg, etc.
I am in the process of trying to get my device in Odin mode, this is where things get REALLY funky! I power the device down, it kind of just vibrates for a while, then it turns itself back on. Well alright, I pulled the battery, I insert the battery, the phone powers itself on. Well okay then, So I pull the battery, put my fingers on the volume down and the home key, slide the battery, and it boots into Download Mode. SWEET VICTORY FINALLY, just gotta push the volume down key to activa... Wait, the screen just went black, and the phone vibrates about every 10 seconds or so. So I pull the battery and try again, only this tie I push the button and get into Odin mode, I see it loading it it's complete I grab my usb cable, and the phone screen goes black and the phone vibrates.
So I have been fighting this for over an hour now and I'm ready to admit defeat unless one of you can help me out and tell me what has possessed this phone and what I can do to free it?
Yes, I did search, I have been searching, frantically, and I will continue to, I have not found anything useful yet
Sounds like a hardware problem. Most likely your power button is sticking. Try hitting it gently against a table corner or something.
Thanks, I don't like the idea of gently tapping my device against a table :/ but I will give it a shot. The plastic button that sticks out the the bezel comes back after being pressed. However I think you are right about the button, it seems a little hyper sensitive.
I had no luck tapping it against a table. I can feel the button click in and i can feel it release

[Q] Doesn't Power On at All. What is the Likely Problem?

My SGS2-Skyrocket SHG-I727 will not power on at all.
The situation is that it was just sitting around on the charger and has been my backup phone for a while. (Been using S4 as primary phone for about a year and am not as pleased with it as the S2-Skyrocket due to the bootloader lock.)
Anyhow - I was wondering if this is likely to be a power button issue or not. All the other posts I have read seem to suggest that the power button issue results in a boot loop. But this unit just died totally. Doesn't seem to be charging anymore either. Wondering if I fried the main board and the power or what?
Any comments from those with experience with the unit completely dying and not powering on all of a sudden would be considered helpful.
read q31 from here http://forum.xda-developers.com/showthread.php?t=2176593
important > no signs of life=no vibrations and blank screen when hitting power button, plugging cable or when trying to enter dl mode
hardbricked=no signs of life=by a bad flash or hw failure
remove battery and leave it out, plug phone into pc or charger, in doing so phone should vibrate repeatedly(this assumes your vibrator was/is working), if it does not vibrate then its dead, how or why idk

Internal Power Button "Stuck"

Hello,
Yesterday my Nexus5 won't turn on when pushing the power button. After plugging it into the Charger it kept on bootlooping at the Google Logo.
When i got home i disconnected the battery and tried again - same issue.
Did some Research after that at and came to the conclusion that my internal power button got somehow "stuck". So i disassembled the phone and tried to pull out the white little power button on the motherboard but it didn't help - the button also doesn't seem to be stuck.
Any one of you with input regarding this Issue? It Phone now randomly boots up for 3-4 Seconds and turns itself off again after that.
Some people on reddit and xda recommened on "smashing" the phone a little bit on the table to unstuck the button but that didn't help either.
thank you
From what I've read the metal piece that the white power button is pushing in is getting stuck, not the actual button itself. I ran into this with my N5 a few weeks ago. People suggested a few fixes: flicking the power button with your finger and storing the phone next to a strong magnet. Not sure how good of an idea the magnet idea is, but the flicking temporarily helped for me, enough to break it from the loop at any rate. Sounds like that didn't really help for you though.
I ended up taking it to a repair shop (out of warranty) and they soldered on a new power switch for ~$60. They didn't seem overly confident it would work, but it's working just fine now.

How do you tell if you fried your motherboard or battery?

Yesterday my power button had some issues, my Nexus 5 was a brick unless plugged in with power, in which the Google screen will go on and off (basically boot looping). I decided to open the back of my phone to take a look at the power button, and got my Nexus 5 working again. HOWEVER when I closed it I forgot about the black cover that covers the motherboard and started trying to put in the screws in, (which was very hard). While fumbling to put the screws in, I realized that I forgot to put the cover on and had to unscrew my phone. But it was too late, I think I may have caused a electrostatic discharge on my motherboard or perhaps my battery due to the electrostatic being discharged from the screw. Though I'm not sure which one is fried, but I know one of them is. So how do you tell if which is fried?
and yes I it was very stupid of me...
currently my phone is bricked, nothing happens if I hold my power button, holding volume + power, hold it for x seconds, tried all that.
though when I plug my phone into my computer, and hold both power and volume button, it becomes connected w/ my computer and I could see it as a device connected to my computer, but then disconnects after a few seconds.

Bootloop + Power Menu problem

So today i started having bootloops, it was showing the Powered by Android screen for 2 seconds then booting again over and over for few hours
Now after it somehow got fixed by itself, i managed to turn the phone ON and to clear Cache
So far there are not bootloops anymore
BUT
huge BUT
the phone is poping the Power Menu most of the time, and then every touch on the screen just "presses" on the Shut Down option
If i press on the Power button myself it shut him down automatically ...
EDIT:
Would like to add, that i never unlocked it, it's the regular OTA version.
I doubt a wipe wll help, but i really wont mind if thats the case
Its almost like something pressing the Power button sometimes, but even WITHOUT the back case it still pops that power menu. even if no one is touching it at all it still pops it once in a while, which cause shut downs once in a while ...
So i woke up
The phone is off, i cant turn it on
I charge it for few hours already and still nothing happens the power button doesnt do nothing, it doesnt vibrate
So i connect it to my PC, it shows it as a Marshal something in the device manager but it KEEPS disconnecting and reconnecting every 2 seconds
I have found a "fix ur bricked phone" threads but they all using a tool that needs the phone connected to the PC, well my phone cant stay connected more than 5 seconds for some reason [ different cables, different computers] it keeps on popping in and out
Did you drop your phone in the water or something? Wet or damp from the rain maybe?
And did you try connecting it while in fastboot or recovery mode?
Maybe wet from Humidity but thats all
i cant reach fastboot nor recovery
as now it all black, not turning on not even for a bootloop
This problem happen when the phone is getting wet ? its certainly didn't but maybe i should "fix" it as a wet phone should be fixed? should i open it and dry it out? maybe take the battery out? its not that easy to take it out tho
I had a phone which was wet from the rain, it made the power button faulty. It would randomly turn screen on off like in your case. I took it to the repair shop and they cleaned the insides and it was fine again. If you're sure it's not the rain or anything then maybe that's not the reason, just a guess.
How about plugging in the charger? Does it light up? If it lit up and you cant turn it on after maybe its the power button problem.

Click to expand...
Click to collapse
plugging the charger doesnt do nothing
Although i got a portable charger with a led , the led turns on when i plug the One, BUT, the led bar doesnt decrease even after few hours, so its like "trying" to charge but not charging anything
Try this from OnePlus Customer Support:
2. Power cycle the One by holding the Power button for 20 seconds 5 times.
3. Attempt to start the phone by holding down the Power button along with the Volume down button to start recovery mode and performing a factory reset.

Click to collapse
or hold Power button with the Volumn up button to see if you can get into fastboot mode.
lol bro... seriously.. you really think i didnt try that stuff before opening a thread?
I already scanned the entire web and no one with the same issue have posted a fix thread
one plus doesnt even care about their customers
Is this the guide you said you saw? http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
Why not give it a try? Follow the steps and see if you are able to unbrick your phone.
I mean there's not much you can do if you can't even turn on your device in the first place :/
