Cannot enter download mode / bootloader with broken power button - Samsung Galaxy S7 Questions and Answers

I have a really big issue. After attempting to get into recovery mode with my S7 which has a broken power button due to water damage it tried to install a system update despite I didn't perform any update and now it shows no command and kicks me into recovery mode but I cannot choose any option because my power button is broken.
I've also tried holding Volume Down + Home Button but when entering download mode I cannot proceed when pressing Volume Up. Nothing happens and I can only get out of there when holding Volume Down for 5-10 seconds and the the first mentioned thing happens again. Is there anything I can do without replacing the damaged part?

Take your back panel off and try fixing your power key manually. However taking your back panel off will remove your IP68 water resistance.

The back panel has already been replaced once (but improperly) by the previous owner and it already has a tiny gap at the top of the phone, so no water resistance anymore. I'll try it out when I can. Thx for your answer

I've the same problem, but it happened after my S7 turned off because the battery reached 0% (I was sleeping).
My power button is also broken, and volume up doesnt work in download mode, but it was working fine in Android.

[Q] Power button...stuck?

So my GS3 has been fine up until about an hour ago. It looks like the power button is somehow stuck to "on," as in, the button acts like it's always being pressed.
The physical button isn't stuck down. It clicks just fine. Here is my problem, I'm rooted with a custom recovery. I can't get into download mode to odin back to stock. whenever I press vol up to go into download mode it immediately reboots or boots the phone up.
Am I completely hosed here? If I take the battery out and put it back in it immediately powers up(hence why the power button is stuck in "on"). Also, another factor proving that the power button is always triggered as if held down is I can pop the battery in and just press vol down and home and it will launch into the initial download mode screen(press vol up to continue).
EDIT: I want to odin back to stock in order to send it in for warranty replacement.

I literally had the exact same problem yesterday and today. What I did was unscrewed the little screws holding the back plate on and this gave me more access to the power button. I popped the plastic cover of the power button off with my fingernail and proceeded to lightly press and jiggle it. This allowed for it to work temporarily which gave me time to odin back to stock and now my phone is being replaced under warranty.
Best of luck!
Have you tried massaging the button back and forth to try to loosen it? It might be easier than removing the screws to access it more. (If it works)
Literally just started happening to me yesterday also. Not quite to that extent, it randomly clicks on and the power menu jumps up over everything I do, but maybe I should return to stock before it does get stuck down. Either of you use the ZeroLemon 7000 ma/h battery and case?

[Q] [Q} Broken Power Button, Phone won't go into Recovery or Download Mode

The power button on my phone recently has stopped working. I need to get it warrantied, but I am running CM 10.2. I need to Odin back to stock, but I can not get into Download Mode or the recovery. When I go into Download mode, the initial screen pops up, the one where you choose to hit up to continue, or down to reboot normally. After I hit up, the screen goes black and nothing happens.
I really need to get back to stock, as Bestbuy are being dicks, and demanding I do a factory reset before they send my phone in.
Anything? I still need help on this.

This has been covered at least 10 times in the past few months we need a sticky. Take your battery out hold your phone so the power button is facing a table or floor and slam that side a few times it should work again (Temporary). You might need to hit it on the surface really hard 10-20 times before it works. Just not to hard or else you might crack the screen. I used a mouse pad to soften the impact. This trick no longer works for me so I ripped the button off. After about a month of doing this I needed to use things that would only hit the button to make it work. About a month after that nothing worked so I just took it off the motherboard and now boot from a off state by plugging into the wall and enter odin mode deny the prompt and it kicks me into a workable state.

I can get into the system just fine. When I go into the recovery or download mode, it doesn't stay in that mode. I tried the banging thing, and it made my power button go from intermittently working, to not working at all.
keep doing it until it works. The button is sticking that is why it reboots/stopped working.

It sounds like your power button is physically broken, and it is activating intermittently, which is stopping the phone from entering download mode. My only experience with this problem is my own phone but ultimately mine got so bad that I had to rip the button off the motherboard, as ThePagel did. Your symptoms sound the same as mine.
You can try this procedure to get into recovery, which works for me without a power button. You will probably have the same problem you are having now with the phone rebooting on its own before you actually get into recovery, because the power button is activating.
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode. If you want to use Odin to return to stock, do that now.
5. If you want to get into Recovery instead, press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.
If that doesn't work, and you can't get a new phone without returning it to stock, then prying the power button off the phone's motherboard may be your only solution.

Nexus 5 Hard Brick situation

My Nexus 5 was drained off battery and was not taking charging suddenly. I entered the hard reset mode( power+volume down button) and accidently did a "restart bootloader". Since then my phone has been hard bricked! I cannot enter into recovery mode as well( power + volume down button). But I am sure that if I can get the bootloader running somehow, my phone will be back. I am sure it does not have any grave hardware issues as such. But the maintenance (service) center says , they will need to replace the motherboard, which is too costly for me.
Can anyone give me any pointers of how can I get my phone working again?

Have you tried connecting it to a computer and seeing if it gets detected by the computer in device manager? If so, it should still be possible to bring it back.
What exactly happens when you try to power it on? Does the screen turn on at all? Does it vibrate once, as supposed to, when you press the power button? Or is it completely unresponsive? Also, when you plug it in to charge, does a red LED light up where the notification light normally is?
Also, try various combinations of powering up sequences. You want to try the following:
Hold power
Hold power + vol down (this should bring you into bootloader)
Hold power + vol up
Hold power + both volume buttons
Let me know what happens when you try this, and maybe I can help you out!

Galaxy s6, boot loop from HELL

Please help me! I own a galaxy s6 (international model, official, not rooted) which is stuck in a boot loop from hell. The led is white (not the usual "boot-up blue") and won't change colour or even turn off. It was the last straw a few hours ago when it randomly restarted, got stuck halfway through the Samsung logo and started making the loudest noise I've ever heard it produce. It was NOT a vibration. Ever since then, it has just been stuck and keeps restarting. When it does get past the "Samsung Galaxy S6" screen it just says 'no command' with the android lying on its back. I'm at a complete and utter loss. It's actually done this a few times this week, but I've always been able to at least boot it into safe mode and uninstall snapchat - which I think is the cause of all this. I can't power off the device, and even when the battery drains completely, the same 'no command' screen appears as soon as it's plugged in. I can't boot it in recovery mode as I can't get it to switch off. I think it may be battery related or even motherboard related. I can't even seem to bypass the 'no command screen. It's just sitting on my floor, charging, overheating and looking all smug. Frankly, I'm pretty damn close to hurling it out of my window.
Also, does anyone know WHY the led is sometimes white or yellow during a boot loop on newer Samsung Phones?
Put the phone in download mode by holding Power + Home + Volume Down buttons. Plug in to Odin and Flash Official Firmware or use SmartSwitch

Thanks but I've tried this several times. The device seems to be completely unresponsive to all commands except a force restart (power key and volume down). I can't put it in download mode or even power it off
have u tried using smart switch emergency firmware recovery? power key and volume down should force it to power down, than enter download mode vol down + home + power key.

Whenever I use this combination of keys it just restarts and it doesn't even show up on Smart Switch when connected to my mac
if you are not be able to take your phone to download mode then repair center is the only solution.

Yeah. It looks like I have no other choice

Galaxy S6 - Cannot proceed past download mode warning screen

I have a Galaxy S6 with a faulty power button.
I took it to a Samsung Repair Centre.
After "diagnosing" the problem (which I had to pay for), I was told that the faulty power button was due to "liquid damage" (it has never been in water everything else works fine).
They said it would cost £180 to repair and would require they replace the whole motherboard.
I refused as I cannot afford that repair and would rather consult a third party shop or purchase a brand new phone.
Unfortunately, the state I received the phone back in unusable.
Before the phone was sent in, it was at least in a state where I could at least use it (providing I kept it charged and did not power it off).
Now its just stuck in a recovery mode => restart => no command (boot loop), and I cannot select an option from the recovery mode screen because the power button does not work.
I planned to flash the stock firmware to try in order to get it out of this loop, and I can get it to boot to download mode as the volume buttons and home button work fine.
However, now when I'm at the cyan warning screen it prompts me for volume up to continue.
I press volume up and nothing happens. I know that these buttons work for a fact as in recovery mode I can navigate up and down.
Any ideas whats going on? or what I should try next?
Videos of the issue
(Tinfoil theory: Did they purposefully lock down download mode after inspecting it?)
If you have time, continuously keep pressing volume up and power until it gets you into Odin. Best of luck.
We're on slightly different devices, but mine has the same defect. The power button failed overnight, it worked to start the device but afterwards, the power button became stuck in the pressed state and I couldn't lock the device (not mechanically, it is still clicky). The volume down button still worked (I don't have to hold power to force a restart because it's stuck in the pressed state), I wanted to take a look at the knox status in the download mode, it didn't respond to volume up, this means that it's dependent on not having power pressed. I somehow got the restart confirmation to show with the power button, twice, so it's not completely defective. The volume down button cycled through being stuck and non-clicky, working normally, and being stuck while being mostly clicky, like the power button, though it doesn't seem to be stuck in the pressed state. It's likely because I kept pushing Volume Down for hours in a terminal emulator. Today, it takes 5 mins of torturing Volume Down to restart the device. Eventually, it might fail completely. This device seems to be able to ignore volume up / down if those buttons are stuck and work almost completely normally.
