[Q] Broken power button / how to boot without

Hello everyone
I own a Samsung ACE S5830. Recently the power button stopped working -- which was annoying, but I could live with. I just wouldn't lock the phone manually.
But now, finally, the thing I feared has happened: I let the battery run down.
My question is, of course: Is there any way to boot the phone other than the power button? Perhaps over USB?
Should the phone show up in adb devices's list, even if it is off? Because it doesn't, but I may be doing something wrong.
I am out of warranty -- so I'll have to get the phone serviced. Is it worth it, or should I just buy a new device?
Thanks a lot for your help.

Sorry to reply to myself.
Just wanted to let you know I suceeded in booting the thing. I don't really know how -- just hitting random keys while removing and re-inserting the battery, connected to usb.
I am starting to wonder if perhaps the power button does at least partially work -- any way I could test it? Obviously it doesn't perform normally, that is, not locking, booting, holding to get the shutdown menu, etc.

Hey!
If you can enter to DOWNLOAD mode(hold together 3 buttons[HOME+POWER+VOL DOWN]), then its probably working.
CHEERS!

Maybe this will be the solution:
1. Hold Home button
2. Connect to usb (or charger) still holding Home button
3. When in recovery menu, unplug usb
4. Select reboot system now
5. Succes?

Just created an account to say THANK YOU! YOU SAVED ME!

use adb reboot reboot commands
with adb you can start shut down download mode etc without touching phone

Well, my power button also kind of stopped working just recently, but if I press it really hard, it works Might be same for you.. However, it's still very annoying..

Do the 3-button trick,but,use volume+,to boot to recovery,then select d/l mode from there,or,follow this guide:

You should be able to get into Recovery Mode using the standard vol up, bixby and power button combo.

Turn the device off. While plugging in the USB cable, hold the volume down and Bixby button. Phone should go into download mode. Worked every single time I've done it. I even just did it using my zero lemon battery case without a USB cable.

Is the Bootloader & Modem the correct ones. When I follow the link/URL it says S9 & S9+ NOT NOTE 9. This could be the reason my phone is stuck in Boot Loop.

turn off the device and connect the cable while pressing and holding bixby and vol down button the press the power button.

I don't seem to be able to enter download mode as well. I have tried all the methods provided and still unable to achieve this.
Anyone can help with this??

Hold volume down and bixby button together only.. Not power button. And then holding the buttom down and bixby put the cable in it should then go to to the download mode

it called volume down. lol

download mode
I recently acquired an unlocked note 9 that kept giving me playstore has stopped working messages. I fixed this, but am pretty sure its a crappy android download that was making this happen. I want to install a fresh copy of android (8.1 is what is on this phone) and I can't get into download mode to do it. When I use the buttons, I got several chinese characters that when translated were not much help. Using the buttons and cable method only caused the phone to reboot back into the crappy android I want to replace. I attempted to sideload the adb and got file error messages saying it could not be read. Any help is greatly appreciated. SM-N960F is the model number. I've wasted so much time on this and just really would like to get it working correctly.

u sure its not a fake? lol
to get to downoad mode u simply hold vol down power and bixby from powered off state
or power off hold vol down n bixby while plugging it in
its that simple
or go to stock recovery then reboot to bootloader from there

None of this works. I never even thought it could be fake since it has all the original parts and box. How would I tell if this is the case? It certainly could be.
Thanks

I'd first look at the S-Pen. The butt end will click in and out of the pen, and the tip should be plastic that's a little soft to the touch. If the tip is metal, it's most definitely fake.

well change usb cable. may be usb cable have some issue.

Question Recovery Hell

My friend has an S21 Ultra 5G with the Exynos SoC. There's an app that constantly crashes, Samsung Audio Remote, that he NEEDS to control the volume on his sound bar because he's handicapped and can not use a physical remote. After a total of 3 HOURS on the phone with Samsung support, the next step and alleged solution is to wipe the cache partition. But I can not get I to recovery. The procedure support told me to use, that I tried 3 times while they were on the phone, did not work. Now, I'm no tech god, but I have successfully flashed dozens of roms on several devices over the years, including 4 Samsung Galaxy devices, so I know a thing or two about pressing buttons in the right sequence. But, this S21 is kicking my tail. It's sooooo much is a trainwreck that I have decided that Samsung does NOT want my money, so I'll be happy to never give them a penny more. But. My friend has this $1000 turd so he's got to get it figured out. So. Please. How do I get into recovery so I can wipe the cache partition on this pile of junk?
Build number is G998BXXU2AUBB.
As a side, this problem exists on his S21, my Moto G Stylus, and his Galaxy Tab tablet, but it does NOT exist on his LG Stylo 3, so I'm pretty confident that even wiping the recovery partition will not solve the problem, but if you've ever dealt with tech support, you know that until you do the next useless troubleshooting step, they won't move on to try to actually solve the issue. So, I gotta do it.

Turn off the device.
Then boot with both the power button and the volume up button pressed (and hold them) until the phone boots to recovery.

In my experience this only works if the phone is turned off and connected by a USB-cable to a computer. If it doesn't sense the cable connected it will just boot to normal Android OS.

It's funny that several websites forget to mention this, they just write about the key combination and rebooting, but without the cable being connected to the PC it won't boot to recovery.

on most devices you dont actually need the cable connected first and some devices do weird stuff like turn on when you plug them in. They probably dont have the actual device.

Yes, yet they inform and post the key combination as if they have tried it themselves.

You needs to connect to PC to reboot to recovery along with combo key started from Android R on Samsung devices. On older os it doesn't requires

Actually you don't need to connect the cable to a PC...the cable has to be connected to a power source. I booted to recovery with the cable connected to my power bank..

Power isn't important, storage is
Wall mount power won't work, power bank, usb storage will do.

I tried that and it didn't work for me, I actually needed to boot into a PC, or maybe it doesn't work with simple slow charge USB? I will play with this to see if it works with another power source.

Try any usb storage if you have, it will work. It doesn't need power.

Even usb c headphones will work

Question Clearing cache partition

I cannot boot in to recovery mode. Volume up & power key won't work (cable is not helping). Any idea?

Timing is everything. Relax... I hit reboot and once the screen flashes off hold the volume up button until the menu comes up.

Won't work. I did try this so many times.

Try this:
Power down the smartphone.
Then wait a few seconds for it to completely shut down. ...
Now press and hold the Power and Volume Up buttons at the same time.
And continue holding these two buttons down even after the Galaxy S21 starts to boot back up.

Not working... I don't know what is wrong.

Unplug the cable if you haven't.
Did you toggle on Developer options?
Try turn it off.

Turned developer options off still no luck. Weird.

If your timing is off with the button push it will do that. Sometimes it takes one time, sometimes 2 or 3. Don't power off; hit restart. Before it starts to boot have the volume up button depressed.

LADB is so much easier for stuff like this if unrooted. once setup properly, just issue out
Code:
reboot recovery

I gave up. I am going to shi...y Samsung Store tomorrow to do this. It is unbelievable. All my browsers lags and I cannot simply clear a cache. Every day I am regretting swap from 1+8 pro. I thought Samsung changed since I had s8 but no - it is even more laggy, bloated. They do and sell the best hardware but simply have no clue about software optimisation. Thanks all for help

I can assure that clearing cache partition will have zero impact to your issues.
Why are you so certain the cache partition is the answer?

Saying it won't work is impossible to predict. If it does work, and many times it does, the issue is gone... a cheap but good trick.
Clearing the system cache is part of the light maintenance I do or when odd behavior occurs.

I'd like to do this before wiping whole phone and re-setup 20x2FA authenticators. It can be dns, webview and much more. So I believe it is good idea start from clearing cache partition

I couldn't get it to work either, until I had the usb cable connected to my laptop - then it was able to boot in to recovery mode and let me clear the cache.
I tried it just with the cable in the phone, the cable in the charger and the phone, no cable and the only way it worked was with the cable connected to laptop and phone with the laptop powered on.
Odd!

That's very strange behavior.
Maybe a firmware, C port PCB or mobo issue.
Keep an eye on it... no likey.

Try this:
Power down the smartphone.
Connect the phone with PC or laptop via USB cable OR while your phone is closed connect a type c USB memory stick.
Now press first Volume Up button and then the Power button (don't leave the Volume Up button)
And continue holding these two buttons down even after the Galaxy S21 starts to boot up.
You will see the recovery options to your screen.

What do you mean?
Only the power button is active at all times.
The volume up/down inputs are only active when as/after the phone is/has been powered on.

Question unable to unlock bootloader

How did you enter download mode? From the recovery menu or by holding the vol up and down and then plugging in the USB cable?

I attempted entered download mode via adb command and then via recovery menu. I only have one hand so kinda hard to enter download via manual method unfortunately.

Yes, it is because that is the only way to get to the unlock screen. And it's not easy to do even with two hands.

Well, my PC is a desktop tower that sits on the floor with USB ports on the front. I'd plug the cable into the tablet and just partially into a USB port on the PC. Then, while holding the up and down buttons with my hand, I'd use my toes to push the cable on the PC the rest of the way in. Just an idea.
