Turn on android USB debugging while phone is off / unresponsive? - General Questions and Answers

(TLDR: OnePlus5, power button not responding, volume buttons physically damaged, USB debugging not turned on, can connect phone via USB to PC, but nothing more. Want to turn on USB debugging to boot via ADB. Or boot any other way, if possible.)
Hello everyone,
Let me tell you the short story of the horrible mistake I made today. I was not able to put my phone to sleep using the power button, which seemed odd. I had dropped it before, so I got suspicious. At some point, I managed to long-press the power button and went: "Oh, looks like the button is working. Lets just restart the phone, I am sure it will all be fine again." ...
Oh, boy – was I wrong. After shutting down the phone, I was not able to restart the phone using the power button. It was not responding, just like before, when I couldn't put the phone to sleep. It was at this point that I noticed, that my volume buttons are physically damaged. By now probably everyone can imagine where this is going. The power button does not respond, the volume buttons – which I need to boot into recovery mode – are physically broken. So I am now sitting in front of a black screen. I am not even 100% certain that it is off.
I know how to use ADB. However, not if USB debugging is not turned on. I never did this on my private phone, as I had no use for USB debugging. I did turn on developer options at some point, but I never turned on USB debugging. The phone does get recognized by my PC, but not by ADB.
So here I am. The phone was working fine before I shut it off and I would like to at least turn it on to see what can be done from there. I am somewhat confident I would be able to boot it with ADB, but it seems there is no chance to do that, because USB debugging was never turned on.
Does anyone have an idea how to go about fixing this issue? As a last resort, I thought about visiting a repair shop, to see if the power button could be circumvented after removing the phone's shell. But are there any other suggestions, before I dump €50 to pay someone that has the tools to open up the phone?
Cheers,
Bunny

Take it to authorized service center and let them try to fix it.
BTW:
IMO the 1st thing of all things every user should do when he gets a new phone is to immediately enable USB debugging ( aka ADB ) this because ADB is the door to phone's Android. And the best part: it costs nothing.

I probably wont spend the money on a repair shop. The screen is broken at multiple points. Who knows what is gonna happen when they open that thing up. I bought a very cheap temporary replacement and on the lookout for new options. Lesson learned. Turn on USB debugging – always.

A bunch of us here are pretty good navigating with with either a broken screen or broken buttons, but with both that's a challenge.
Some have even managed to enable ADB and authorization in the OS from TWRP.
If you already bought a replacement I'd open it up and see if you can get the buttons working again.

After letting the power drain from the phone, I noticed that the power button is not actually malfunctioning. When I try to turn it on, I *do* get the message, that power is too low. The volume buttons are definitely physically beyond repair (would need to exchange), but the power button still works (as it looks like). So I can "turn on" the phone, but it does not boot correctly. (?) Does this new information tell us anything? I guess the biggest problem is that I can't make it into recovery mode without the volume buttons? I have tinkered around with the iFixit Toolkit in the past. I am not sure if I want to spend that time (and money, since I don't have the toolkit anymore).

Charge your phone for at least 30 minutes before trying to restart.

Yes, I did that. But it does not start. What I meant was: The fact that power button returns the "too low battery"-message, when the battery is empty, means that the button itself is not broken. I charged it overnight, but the phone remains in black-screen (and does not trigger the usual "vibration" upon turning on). So my conclusion is, that the button is working, but the still does not boot correctly.

AFAIK a phone only starts Android OS if its battery charge level is >= 5%.

Alright, but what does this tell me? The error message appears when I let the battery drain purposefully. The OS still does not start after charging overnight (without any error message, just black screen).

Battery might be defective.

If you think the power button is working have you tried holding it down for 30 seconds to see if the phone will reboot, or vibrate, or anything?

Yup, I have tried holding down the button for minutes. Also, I believe the phone is charging. After leaving it connected over night, I need to wait approx. a full battery cycle to produce the "battery too low"-message again. The only thing the power button allows me to do, is produce the "battery too low"-message.
I guess the damage is more severe than I initially thought. I already bought a cheap, temporary replacement. I think I won't pursue this issue further. I guess I could try to flash it, but without recovery mode (no volume buttons) or USB debugging that sounds like quite an undertaking.
Thank you two for trying to help out!

[Q] Trying to root, cant get into download mode

Im following this here:
http://www.techzek.com/how-to-root-samsung-galaxy-s-blaze-4g-sgh-t769-smartphone/
But the power, vol up and down get it to show the yellow "warning" thing that im supposed to see, but it goes away after like half a second so I cant get into it. What else can I do?
how to get to download mode.
As you press the volume +/- and power button , simultaneously plug the micro usb cable into your phone (this cable should already be attached to your pc). This should do the trick.
Happy rooting.
The instructions in the first post are wrong, and should be updated. You have to have the cable plugged in. In the video for example, he has the phone plugged in the entire time. You're not required to have three hands in order to get it done.
I've had no luck with any of the variations on this method either.
Turn your phone off, hold both volume buttons and with your usb plugged into the computer take the other end and plug it into your phone while continuously holding the volume buttons. It will boot into the caution screen and than you press up to get into download mode.

If none of the above still don't work try this
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card
5. Plug in USB from computer
6. Hold volume up + volume down
7. While still holding the volumes insert battery
8. Should now be in download mode

Thank you both for the replies. I've tried both methods several times without success. I'm tired now so I'll quit for the night. I'll try again tomorrow a few more times. If I can't get it to work I'll take it as a sign that I'm not meant to root this phone. I must have tried 30 times today; it gets old.
Update:
I've tried this ten or fifteen more times. I'm finding that the yellow warning message, whatever it is, doesn't appear at all, ever, unless the USB cable is not connected when I put the battery in. If the USB is connected, I get the gray battery icon every time, no matter what else I do.
If I do connect the USB, with the battery out, I immediately feel the device vibrating every second or so, as if reboooting.
I tried removing the SIM and SD cards again. This had no effect.
It's very strange. In that video the entire process looks about as easy as doing a simple battery pull. It's just not working for me. Is it possible that Samsung made some of these phones "root-proof"?
Worst case scenario you will have to buy a Samsung jig.

I had to do it a few times myself.... It did not catch for me the first 3-4 times...
Then it worked. Make sure you are holding down all 3 buttons down tight.

I think I've tried it at least 50 times now, with variations, and it's just not happening. I freely admit my ineptness, but holding down buttons is something even I can manage.
By "three buttons", I take it you mean two. I don't have separate volume up/down buttons on my Blaze; just a single rocker button. That's what you mean, right?
I did get as far as the warning screen, but from that screen there is no option for pressing up to go into download mode, so it seems that my warning screen is different from others'.
I guess the next thing is to research "Samsung jig" and figure out whether this is something I can possibly do.
I went through the same thing, I too thought I had to purchase a jig but the method I posted thanks to another member saved me, try again with a modification to step 6
1. Turn off phone
2. Remove battery
3. Remove sim card
4. Remove SD card

Thank you. I just tried it a couple of times, without success. I have to go out now, but I'll give it another few tries later.
If I have to get a jig, should the Samsung Galaxy S be compatible? I'd think so, but I don't know for sure.
This is a slight variation of what everyone is suggesting...I was also getting vibrations when trying other methods.
Turn off phone
Unplug battery
hold volume rocker, make sure you're holding down both up and down
Insert battery
Hold power button until the warning comes up...only takes a few seconds
I said three buttons, because it seemed (at least to me) that you need to hold sides of the volume button down at the same time. It does not seem to be just a up/down button.

Thanks for this suggestion, but it also didn't work.
This method, like some of the others, takes me into what I think is Recovery Mode. I'm not sure, because I don't really know what I'm doing. The message that flashes on the screen isn't really a warning. Doing it this way, i.e., releasing the power button but not the volume button after the phone starts, takes me to a screen that says,
Android system recovery <3e>
at the top. Then there are some options: reboot system now, apply update from sdcard, wipe data/factory reset, wipe cache partititon. I can use the volume button to select an option, and the "OK Key", whatever that is, to select.
Near the bottom of the screen, in yellow, is the text that I couldn't read before:
-- Verifying internal MMC block...
checksum confirmation -> check(0)
Not need checksum confirmation
already executed!!...
# MANUAL MODE #
And that's it. In the background of this screen, grayed out, there's a white triangle with a yellow exclamation mark in it and a little green android.
Is there a way to get from this screen to Download Mode?

I guess it might if I could get ADB to work. So far, no luck; but that's a whole different problem. There are pages upon pages of posts here from people having difficulties getting ADB to work, so it'll take days or weeks to sift through all that and figure out what I'm doing wrong.
I thought the actual rooting process would be fairly simple, and it would only get complicated when trying to install custom ROMS and that sort of thing, which I'm not trying to do. It appears that I was wrong. I think I just don't have the knowledge to do this.

Make sure you have Kies Air turned on when you try to connect. You can use USB or wireless mode then. I tried and without Kies, it would not connect.

So I should have debugging mode and Kies Air turned on, and then ADB should be able to find the Blaze? I'll try it tomorrow.
Thank you.

[Completed] [Q] razr m wont turn on after super su rebooted it?

Long story short. I finally got brave enough to root my phone. I did it successfully. then I think I killed it . http://forum.xda-developers.com/dro...-droid-razr-m-xt907-183-46-15-t3030852/page58
Then, while trying to get the Verizon wireless hotspot hack to work following these directions, http://forum.xda-developers.com/droid-razr-m/general/guide-faq-how-to-root-boot-unlock-t2869432, I got to step 2 and for some reason the changes wouldn't save. so after doing some searching, I read that another person had tried another superuser app and was able to save their changes. So, I downloaded the superuser app and took off the original super SU. Then I kept getting an error that said, I didn't have root access. So I downloaded the original app. I had before from the play store and proceeded to replace it. The app installed fine and then said that the device needed to be rebooted. I hit okayand the phone turned off.
It never turned back on. Pressing the power button for any length of time will not turn on the device. When I press the power button along with the down volume button and hold them after releasing the Motorola logo comes up and then the phone goes dark again. like it's off. It doesn't have any blinking indicator lights nothing. When it's connected or disconnected from the computer. My PC makes chiming sounds like normal, even though the phone looks like it's completely off.
When I plug it into a charger, it stays completely dark, with no indicator lights like it's off. While its plug-in if I push and hold the power button still nothing. if I push and hold the power button and the volume down button, while it still plugged in,the Motorola logo comes up and then nothing again like it's powered off. The second time I repeat that procedure. The battery indicator comes up showing that it's charging. And just to let you know that the first time when all this happened and I saw the battery indicator it was charged at 80% still, so that's not the problem.
so my question is, did I brick my phone? is it permanently bricked? Is there anything I can do about it? or should I just look for a new one?
thank you for any help you could offer.

Power Button Issue

Good day guys.
I suppose most of hammerhead owners are familiar with the issue of the power button.
Well I'm beyond that. I accidentally dropped my phone from a 2 meter high spot, fortunately my case is strong, but since then I experienced a very weird issue, I didn't find anything similar online.
So my issue is that the phone reboots, but how's that different from the common issue?
Well when charging or plugged in it doesn't reboot. When a task such as music playing while not plugged (even silently, which is my solution for now), the phone doesn't reboot. But if there's no task running, if you press the power button putting phone to sleep, if the sleep lasts 2 seconds or more the phone immediately reboots.
There's no bootloop or anything.
I know the issue needs my to open the phone and fix the button, but I wonder why only while unplugged only.
Thanks for your time
I had this same problem. I immediately enable usb debugging, then ripped out the power button. before i ripped it out, it got stuck and was rebooting like yours was. now, if I want to turn it on, all i do it connect it to my pc while holding the volume down button (this accesses the bootloader), open cmd on PC, fastboot reboot, and its on. Sadly, this was the only way for me to continue using the phone. Such a good phone.

You said you dropped your phone and started experiencing weird things. It's hardware. Your power button might be messed up. Replace the power button (needs to be done professionally.)

Factory reset A7 2018 to remove lockscreen

There is an A7 2018 with lockscreen on, but the owner don't remember it. So it need to be remove by resetting the phone. However, unlike all the video on the net, this phone actually at the screen where "password is required after restart", not the actual lockscreen itself. This is where the problem lies. I've tried getting into recovery mode with the button combination, but the phone won't get into it. There is no turning off the phone, because it requires password to do so. I've tried everything, vol up+power, vol down+power, vol down+power and when the screen turned off switch to vol up+power, and repeat them all in case I didn't time it right. The phone just won't boot into recovery. Also, it won't goes into download mode as well.
So, was it the phone's security that was blocking me, or I just haven't tried everything yet. Spent half a day working on this phone, ended up nowhere.
Forced reboot is done by holding VOL DOWN + POWER for around 7 seconds. Once it's rebooting, hold VOL UP + VOL DOWN and plug usb. You have to do this when the phone is off and not yet vibrated when turning on.
I will try to find some way to help, but force reboot should work ALWAYS.

it is hard to know if developer options with usb debugging is enabled on your phone..
but u can try adb commands..
just Google & try..
or take your phone to service centre..

I don't say you stole this phone or anything, but I am not going to teach you how to unlock safety on a phone because there is a good reason that safety feature is there.

Oh come on, there is not a single thief in this world that will lose time to check forums and waste hours like the colleague above or me ,trying to fix a phone ! All with gsm repair services had stolen phones in their hands for sure ! If one customer comes and says give me *lets say half the price for a s9* for a s9 , you wouldnt give them the money and buy the phone? of course you would ! We are all humans trying to make a living. Extremely few people would hold back and ask questions ! And sometimes , when buying phones, you can get some that are stolen, can`t catch the thief, can`t recover your money ,unless you remove frp, bypass security, remove icloud , thats just the way things work ! no point in hiding behind a finger. You sometimes get rekt ! and buy stolen phones without even knowing, or willingly buying, because if not, the competitor will buy it and ruin the market price for you ! Good luck to you all !

Black screen issue, i can't restart the phone

Hi! I'd like some help.
I have a Samsung Galaxy S10e (SM-G970F).
The power button is faulty, I got it back from service yesterday, unfortunately it was not repaired because the device is rooted.
Before I handed it in for service, I was able to turn it on without the power button (download mode -> restart), but now the download mode is not available either.
And it doesn't indicate charging either, the display is completely black at all times.
Yesterday the computer recognized it as a drive, but it showed only one TWRP folder. Today, unfortunately, the computer does not even recognize it, nothing happens when the usb cable is connected.
Is it possible that the device has remained in some service mode?
Somehow I would have to reboot or get into download mode, I just don’t know how..
So now:
The display is completely dark.
It does not respond to buttons.
The power button is broken.
It does not indicate charging.
The download mode does not start.
The computer does not indicate a usb connection.
The adb doesn't see either: error '(null)' not found.
What can I do?
Probably is bricked by the shop you leave to repair, get back to them

Thanks for the suggestion.
I can't go back to the service now, I made a complaint in writing before yesterday about this, the investigation time is 30 days.
However, I have new news about the device.
I realized that the device itself works, only the display is always dark.
I disassembled, unplugged the battery from the motherboard, and switched back to download mode and Odin recognized it.
I managed to update the software on it, the device restarted fine, only the display is completely dark.
The computer already recognizes it, I can give a command via adb, and I can hear the volume button when pressed.
The only problem is that there is no picture on the display.
I reconnected the display connector to the motherboard, but that wasn't the problem.
When the power is off, the display does not indicate that the charger is connected.
Does anyone have any idea what else I can do?
Try this command (It toggles the display on and off ):
adb shell input keyevent KEYCODE_POWER
