Phone won't turn on at all - Help?? - Samsung Galaxy S7 Questions and Answers

Hey there,
So recently my phone got updated, and when I got my phone out of charging, it simply turned off. I thought "Oh, well lets just turn it on", well the thing is, the phone doesnt respond to ANYTHING.
I have already tried booting into multiple modes (normal,recovery,safe mode, hard reset) but NOTHING works at all.
The phone just seems dead. I even plugged it on my computer, but of course it cant recognize the phone either.
I am looking for some master mind, telling me what should I do to turn it on, or maybe it is hardware error/damage? I never really dropped my phone, even it have just a few scratches.
Thanks for further answers/solutions!

Hi
By hard reset you mean power +Volume down?

I guess you already tried a different charger and cable.......
Check the push buttons make sure they are not stuck

The push buttons are perfectly fine, even the phone isnt that old, to be broken, as I stated, I took a good care of it
I guess there are no ways to fix this then? I will better call my service then.

Is very difficult to fix when it does not turn on.......is most like it that it has to be open to check.......the best would be that , take it to Samsung service
let us know what happens

Leave it connected to PC USB overnight, see if it can trickle charge
If it works, buy a new charger & USB lead

[Q] Transformer not powering on?

Hey, I got my transformer yesterday, and for some reason this is the 2nd time this has happened, fully charged battery, but the device won't power on. Attempted to plug into power but no dice. Held the power button for 30 seconds, nothing, held the power and volume up and nothing. Yesterday when this happened I plugged it into my computer (Windows) and held the power and up buttons and it turned on though it could have been windows detecting the drivers. Anyone else having this? Any suggestions? I haven't had a chance to test again and see if I can bring it back through that trick yet, but I will. Then I'll try a factory reset and see if it resolves the issue. I would hate it if this is a defective unit, that's for sure esp since they are so backordered. Outside of that I love the device.

when your device isnt coming on, does your computer give you a usb notification? You could be putting it in apx mode on accident.

I will find out in a few. The thing is this has happened when I left the device unplugged and in sleep when driving to/from work. Yesterday plugging it back into the computer brought it to life. Nothing else did. Not sure what apx mode is even.
Sent from my MB860
EDIT: Ok, turns out it get stuck in some weird power mode. I plugged it into the computer with no resolution, when I held the power button for 10 seconds, then waited 5 and pressed it again, the device powered on. I suspect it might be an issue involving detecting WiFi access points when driving or something else. I'll Factory Restore and see what happens.
try turning off screen lock.

I had that sometimes in the first day I had it, after that it hasn't happened. No factory reset, just make sure to do a hard shutdown (powerbutton 10 sec~) while it's booted and it should fix the issue.

Yea, it had happened once already, and again. I'll be testing today when I leave work, factory reset and see what happens. Should it continue, I'll go to the next step. I'm just not sure what it is. Interesting bug to say the least.

From the way you are describing getting it to work again, it sounds like you were in apx mode...

I still don't really know what APX mode is, from the limited things I have seen about it, in order to get into such, the device has to be powered off first. As far as I can tell, my device isn't randomly powering itself off and automatically going into APX mode. This happens without me touching the device. When I did the power off and on today, it wasn't plugged into the computer at all. There was no recognition from the computer that the device was plugged in.
Well as of today, my EEE Transformer is dead. Will not power on the screen, Asus offers a repair of 14 business days, unacceptable.
Powering on issue
Woah...I was scared to death when mine didn't turn on the next morning that I got the device. Charged it for an hour and try to turn on again, nothing.
Holding the buttons several different ways that I know how to reset it didn't work. Finally I held the button down for more than 10 seconds. Wait a few seconds, then it powered on. Why didn't they make a hard reset since you can't remove battery!??? Hope this is just some fluke and could be updated with firmware.

Alas, mine didn't get resolved with that, computer detects it now, but no screen response. Asus tells me 14 business days to fix then says try to restore it with the Kernel Source Code. Unfortunately I can't see a way to do such from the folder and they decided to disconnect me.
There is a bug with the default lock screen that makes it so the screen doesnt power on occasionally. In order to work around this you need to disable the lock screen in the settings, or change it from the default one.
Obviously in order to do this initially it needs to be powered on and so you can see it. Therein lies your problem of course. To get around this, charge up your device so you know it has power, use the force power off method (10-12 second press of the power button), wait a few seconds (30+), then power on the device normally (5-6 second press of the power button).
If your screen doesnt come on after that, try a couple more times. It really is an RMA job if it continues to fail. If it does come on, let it boot up to the lock screen, and dont let the screen go off, keep it 'alive', unlock the device and change the lock screen in the options, to either be switched off, or to anything other than default.
This wont work for everyone, as obviously a few may actually have duff screens, but for some of you, it may just be the lock screen bug you are getting unlucky with.
Yea, I seem to have not only the lock screen bug but a defective screen. Unacceptable to me, but hey, what can I do? I've been disconnected 5 times so far, waiting on a manager and will be requesting a faster resolution than what they are offering me. (10-14 Business days is unacceptable)

i am in the same boat as you, luckly i picked up the acer for the weekend because i didnt think i was going to get the asus. glad i did
I'm waiting on hold with Asus to see if they will do an Advance Repair, basically I get put on the line for the full price of the device until they declare mine broken since the return period on the Acer is 14 days at best buy. Quite outside of the repair period.

Had to escalate it up to management and expressed I wanted an advance repair and was willing to give them my credit card number so they could place a hold on the card for the amount of a replacement until they got mine. Has to be escalated above the rep should hear back in a couple hours. If not I have an extension and will call back

they are having me download the source code and try and force it to the transformer we will see if it works will report back

[Q] Nexus 5 Dead

Hi everyone, so yesterday I got home, and like everyday I dropped it on the wireless charger. After about 2 hours I took it and it has turned off itself and doesn't react to my button presses or anything. I tried holding Power, Power+Vol Up, Power+Down, Power+Vol up+Vol down, charged it overnight but it still doesn't work. Is there anything else left to do? (Bootloader is unlocked, twrp recovery + franco kernel and stock fw, it was working for like 2 weeks with no crashes).
If you've already tried holding the power button for 20 seconds it sounds like rma is the answer.
Does your computer recognizing your phone?
It does not, the phone isn't turned on, how could computer recognize it? (btw. The phone takes the power from the wall it seems, cause the power cord gives a noise when only it's pluged in without cable to the phone, then I can take it out, it still makes noise, and if i plug the phone into it, it stops making the noise)

It can recognize a phone even if it's not turned on,as adb,and then you can flash recovery,kernel and etc,using fastboot commands.
So go to device manager and see if recognized as adb,if yes,you're good to go,and try to flash stock rom and recovery.
Also you can try to reboot into bootloader using fastboot reboot command.

Ah yes,my bad,sorry. Also,when you took,didn't you notice that it's hot or something like that? Because I've read on the internet that wireless charging can make devices to overheat.

Yes, 2 times it was hot, but not yesterday. When I took it, it wasn't cold or hot, the same as normal phone would be.
Oh, and one more thing. When I hold power button it makes noise like this: h\ttp\s://w\ww.dropbox.c\o\m\/s/d3e0rqtlzm7x2ig/N5noise.mp3 (Remove all the \ from the link)
Barely hearable so I just accidentally noticed it.
Anyways, I'll go for the RMA. One more question, I really doubt it's possible but I will ask. is there a way to transfer all files from the phone if it's not responding to anything?

If your sending it to google, then you don't have to worry. However, your device is fully dead, right? They will most probably swap the mobo or just send you a refurbished piece.

It's making some kind of a noise when trying to turn it on/charge it, and doesn't react any other way, so yea, dead.

s7 hard bricked (qualcomm version)

Hi,
I flashed a rom that did something bad to my phone. After reboot it just stays black without any response at all.
I've tried all the key combinations and just tried the USB Jig (confirmed the jig worked on my S3) but nothing.
Is there any way to get into download mode?
I've heard about JTAG, but not sure if that will work.
First, try to connect the phone to your charger to see if any LED lights up, if this doesn't happen, try connecting the phone to your PC and see if ODIN detects the device, if that also doesn't work...the best course of action would be to send it in for repair, although chances are you've hardbricked it.

Possible it is stuck in some sort of loop, without having any LED to indicate it would be impossible to know
The charger doing nothing seems strange though
If you had an LED showing I'd suggest waiting for the battery to drain then trying to enter download mode again, but I guess if you've tried everything else and are considering opening it anyway for a JTAG, then disconnect the battery first, see if you can get back in after reconnecting it

Yea tried all that but no luck.
I will try for the JTAG, but need a heater I doubt a hairdryer will be enough to pull the back off.
Also need the JTAG machine itself
opened the phone and removed battery but still nothing, it seems JTAG is the only way.
anyone knows how that works?
Are you getting some sort of output?
I'm using the Exynos variant, I've yet to encounter anything that wasn't solved by holding power+vol down+home for 40-50 seconds (it'll boot to download mode eventually usually)

Tried for one minute and no result.
No output at all, nothing gets recognised in windows. No LED, no nothing...
Well, some users also reported sudden blackout with no response at all, it turns out it was an emmc failure. He then proceeds to send in his phone and luckily, it was replaced. Your mileage may vary, you could try playing "dumb" with Samsung. After all, with the phone dead there's no solid way to tell if KNOX was tripped.

rooted S6 dead after factory reset

I wanted to factory reset my phone as one of my friends needs it for a few weeks/months,
phone shut down, went into twrp, shut down again and now its completely dead.
No way to get any signs from it, I dont get any response from my screen when plugged in to charge and the LED does not light up either.
Plug in wall wont work, PC connection wont work, Powerbank not working and wireless charging doesnt get any repsonse either.
Its just straight up dead, if there is nothing I can do then oh well its my old phone anyways, would still be grateful for any help tho as my friend is in a hard situation rn.
Ty in advance to everyone trying to help.

two ideas come to mind, 1: a jig and 2: debrick image
jigs should still be a very viable option for situations like these, however might be fruitless and i cant remember if this phone has an expandable memory slot or not. I know they ditched a few things on the S6 that were like VGN "what were they thinking???" but cant recall if that was one of them

Bricked OnePlus 7 Pro?

Okay, so I know this has been posted a lot but I am pulling my hair out!! :crying:
So this is what happened, I downloaded this app from google play. It had 4.8 rating, whatever. But it's purpose was to, keep your game playing in the background when your screen is locked. Everything was working fine, until my phone lagged and restarted, I got it to turn back on like normal. But then, random shut offs has been happening ever since.
I decided to do a factory reset on my phone, it was okay for a day, but when I played a game on the phone, it crashed
and shut off again.
Now it won't open, i tried everything! and when I say everything, I mean every basic way to restart it. Except flashing it. Because it can't even turn on on it's safe mode. it has been on a coma for 3 hours now, it is plugged now on its original power brick and chord.
My pc doesn't recognize it.
I have 2 questions, will I still be able to fix this? And, can a technician fix this. Like 100% fix it when I decide to go to a tech tomorrow?

Try after few hours and check if the pc detects it. Technician can fix it but try one time on the pc tomorrow before your leave for technician. Also change the usb cable and try.

Thanks! I already tried changing the cable, I will try again once I get home. But, if it won't work, I'll go for the tech. Do I have to go to a oneplus tech? or any mobile tech can do? I read that this is "Hard brick" and somewhat impossible to fix. I really just need something to calm me down. LOL! so you telling me that a tech can fix it for sure, made me a little less worried.

Best will be sent to oneplus if accessible either you have warranty or not. If that's a hardbrick then you can't be sure if you local technician can fix it.

Well, we don't have Oneplus "store" here, just resellers, and they don't offer warranties nor fixes.

Not the power button. Volume buttons. You can get in EDL mode that way and maybe it will be recognized if bricked. There are 2 possibilities, it's either brick or hardware damage. If bricked only, it can be unbricked. IF damaged, well, the Service center.
Try this:
Power your device off
Maintain volume up and volume down keys to get into Qualcomm EDL mode. So, Volume Up and Down together hold and plug the cable in while holding the buttons. If you get any detection, there is hope.
Use MSM Tool, of course with corresponding ROM for flash.
