I have problem with power button in Redmi Note 5 pro, the system doesn't respond to power button sometimes, can't turn on device by power button because sometimes holding button is not working sometimes. I entered into Fastboot mode and used fastboot reboot command, any way to fix that? clean something, or just go to phone service?

It probably a hardware issue, taking the phone to service center seems the right choice.
Please try the following if the power button does not work again. Press the silent button once and then the power button. If it works then, it could also be a software problem. I had this behavior with the Havoc-OS rom. Since switching to Arrow-12.1 I have not had this problem until now.

Hello, sorry for my english.
Since a few weeks I can't turn on the phone. When the D855 isn't charging it keeps in LG logo loop. If I plug it the charger it turns on but when I write my PIN Code its shutdowns and again I got the LG logo loop (with the phone charging). I have to remove the battery to try again but I can't use my phone...
Some help please!! I haven't find any post with that trouble, sorry if there are some solution in the forum
Thank you!!

I tried that but doesn't work. It continues in LG logo loop. What could I do? My PC can't detect my phone too.

put the usb cable in your pc, not on the phone, then press and keep it the volume down pressed, and now connect your device without realease the volume down key, see if they go to emergency mode or download mode!

I did that you said (but keeping volume up pressed, with volume down it did nothing). It enters on download mode but it only keeps in this mode like 2 secs, if I keep volume up pressed it enters again and again, if I release the button it restarts to LG logo loop.

so, nothing you can do to solve the problem, if you are in guarantee time so the only thing you can do is sending the phone to LG Service Center to try fix the problem or maybe replace it!
I have a MTCB KGL that was running Android 4.2.2. I now flashed it to 4.4 with the Malaysk rom. The flash went ok (it said) but when it rebooted it was stuck at the first screen (kitkat logo shows, and 'multi-media on-vehicle is shown). I cannot get into recovery either, so I'm kind of stuck.
Is there some other way to reach recovery, besides trying all methods described below?
1 Press reset button and power button together
2 After about 5 secs release reset button, but keep pressing power button
3 When booting screen appears release power button.
4 It boots into recovery.
--Update 1-- some units without front USB have a different procedure
Firstly power on the unit and then long press the power button and then reset. Then the unit will get three rings and you loose your hand on the power button and short press the power button again. (thanx @netay)
--Update 2-- some others have this procedure (thanx @R4D3N)
1. Turn off the unit by holding 3-4 sec the power button.
2. Hold the RESET button + POWER button for 5 sec
3. Release the RESET button and keep pressing the POWER button for 2 sec
4. Release the POWER button and wait. The Recovery menu appears.
5. With the Volume knob you can move up/down and long press on Volume/Power button to select the option.

Do you have a hardware power button. I have kgl unit with hardware button and i can enter recovery by switching unit off then switching on by pressing and holding the power button for 10 - 15 seconds till the unit lights flash. Release button and unit boots into recovery.
Did you follow the update instructions exactly including wiping data before and after install from the recovery menu.

Hi, thanks for the reply.
Yes, there is a hardware power button. I used it with the reset button before to get into recovery. But now it just hangs on the first screen. None of the 'known' methods of getting to recovery seem to work.
The power button works though. I can switch the device on/off, but that's about it.
I did follow the instructions correctly. I was not able to wipe data after the install because the device rebooted automatically after flashing, and then got stuck.
Hi all, have two problems:
1) My power button stopped working long time ago. But it's some mysterious. It doesn't turn off or on screen and it doesn't accept options in bootloader. But it DOES reboot tablet if I hold power button.
I was trying to clean button with alcohol and make it work, but nothing helps. I think that button replacement won't help (I didn't try).
2) I wanted to install new ROM, but I can't. I stopped after flashing recovery, 'cause "No command."-screen appears, where I should use my NOT WORKING power button.
So my questions are:
1)any suggestions about the problem with power button? (Solution of this problem will solve second problem)
2) how to enter custom recovery without using power button if I had "No commans." stock recovery screen?
Thanks a lot!
Type "adb reboot recovery" from inside Android. Same for rebooting to fastboot or bootloader. It's easier, especially on the Pixel 2, than trying to get button presses correct.
If you can hold the button down and reboot it's apparently working physically.

Thanks for quick reply.
Yeah, I enter recovery by "adb reboot recovery", but I have then "No command." screen where I need my power button to skip this screen and enter TWRP.
I've not seen that screen with TWRP, only with the stock recovery.

Interesting. I opened my N7 to check the buttons connector's configuration. Please verify the following:
disconnect the battery and measure pin 1 and 8 with an ohmmeter while pressing the power button - I get <1oHm (short)
reconnect the battery and measure voltage on pin 1 - I get 4.0V
Well?

Have the same with yours
So I am normally using my phone scrolling through social media but it suddenly froze so I tried to hard reset it, but it goes in to a bootloop without any display on the screen. I could tell it is on a bootloop because of the repeating vibration everytime the phone boots up.
My device is Poco F3 (alioth) Running stock MIUI 12.5 bootloader unlocked and rooted with Magisk.
Things I have tried:
Long pressing power button, long pressing both power button and volume down button, long pressing power and volume up button, then long pressing all of them.
Plugging it on my PC but it doesn't even detect it. Tried inputting
Code:
adb devices
and
Code:
fastboot devices
Still doesn't work. I even made sure that my drivers are working so I tried it on my brothers Poco F3 and the PC can detect his phone through ADB commands.
Waiting for a day if it magically turns on again. Nope.
Charging it up because maybe the battery is low. Nope.
At this point my only two choices is opening up the back panel then replugging the battery so it completely turns off and hopefully boots up. But its a risky task since I don't have special tools to open up my phone, and my another choice is just bring it on a service center.

If the phone is bootloader locked don't do anything, take it to service center it's out of your hands.
If service center intends to charge you something well you could find some people online with edl accounts to do flashing for you but this sounds like hardware issue if you don't see poco logo ...
Edit: Sry didn't read the post fully - did u try fastboot devices when in fastboot mode - volume down and power ? If it is recognized and bootloader unlocked you can try flashing - go with xiaomi firmware, last thing you want is to be stuck on custom firmware when you take it in for repair - again only if bootloader is unlocked
since your brother pc can recognize, tried fastboot miui.eu on his pc
but I had this problem before and the only solution is to change mainboard on the xiaomi service center.

Do you have any clue as to why this happened? Any mods done besides applying Magisk?
If the software got damaged, you could try the EDL Mode but that's difficult. Should be your last resort.
If hardware, then I don't know unfortunately...but then how?

If it's recognised by your brothers pc, try that pc for flashing stock fastboot rom using miflash, and don't forget to choose 'flash and wipe' instead of 'flash and lock' in bottom right corner of miflash. Let us know how you get on
Happened today. Random bootloop while under normal use. Also occasionally attempted to trigger the emergency SOS call when power BTN clicks 5 times.
Saved by a solution in poco x3 thread.
The failure mode I experienced was possibly a "sticky" power button.unsure if it's an electrical short or something mechanical in nature tho since it's intermittent triggering of the power button.
Temp fix was some quick clicks of the power button a bunch of times(20-30 clicks?).
Also shut off the emergency sos function.

Same... it started calling emergency number and wouldn't shut off by holding power button.
Worst device ever

My mi mix fold is dead. (Black Screen)
I open the game to play and it crashes
I press the power button the screen turns off
And the bad things started
Can't boot even though I tried many ways
1. Reset: Hold Power 10s ++ -> Not work
2. Recovery mode: Hold Power + Volume Up -> Not work
3. Fastboot: Hold Power + Volume Down --> Not work
Can you give me some advice on how to handle this situation?
I only have one option EDL Mode left but I don't know how to do it on my device
I know it's possible to use hardware nodes, or TestPoint
So I would like to ask how to start EDL Mode on my device?
I had a bootloop issue on my Xiaomi Mix Fold 2 yesterday.
All of the above didn't work, so I had to force a reset by:
hold vol+ vol- pwr
Once it reboots & you see the MI logo, keep pressing the vol+ button for a few seconds.
Leave it be for a few minutes & hopefully it should have reset.
I did everything but it didn't work
I hold the buttons together for 2 minutes and still can't see the MI logo
