Hello,
Give more information please
like did u modify the system before
can you see something download mode?
::How to get into odin/download mode::
-turn off phone / or remove battery and put it back
-press power + vol down + home button together
or Recovery Mode
::How to get into recovery mode
-turn off phone
-press power + vol up + home together
Maybe you set the brightness to a low level which caused such a problem as it seems.
the most known issue is the screen flickering, but it may be related to screen being blacked out
What can you try
-turn off the phone by taking out the battery
-put it back in and power the phone on, once it boots you have to wipe the screen
before the screen turns off
-increase the brightness and disable power saving and auto brightness if they are enabled.

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
Hi guys, this is my very first thread so here goes nothing,
I recently damaged my S8 + power button and it is no longer operational, however i have been able to boot to download mode and reset device after it going flat and not turning back on and staying in a bootloop while plugged in. Any way so my new problem is that it went flat again and i plugged it into charge and it automatically boots into recovery mode and when i manage to get it into download mode pressing volume up or down does not work. Any way to fix this and get my phone back up and running?
I can definitely see that being a ***** because you need the power button in sequence with Bixby and a vol button to get to download mode or recovery. Id prob root the phone and install quick shortcuts app that gives you on/off/reboot/restart/ options it might help you. But replacing the power button is a simple procedure and I'm sure it's very cheap to. Id fix that button and problem solved.
Please help me. So recently I've been having this screen overlay detected issue and I'm trying to resolve it and one of the ways I found was to go in to safe mode and disable all draw over apps. I'm ok with doing that and I know how. You hold down power button and then hold down power off on the screen. The issue is that my phone doesn't have a notification after holding power button to power off, restart and put to airplane mode it has a slide to power off a button to restart and a cancel button to cancel. So I need help to finding out how to put my phone into safe mode when everything I've seen says to hold down power off on the screen, but I don't have a hold down to power off!!!! Please help me btw my phone is called Leagoo M8 Pro.
Hi,
A friend of mine gave me his Samsung Galaxy S6 because he knows I know a bit of smartphone repair. (I have installed a lot of custom roms, replaced screens, batteries, ...)
But I can't seem to solve his issue.
After charging at night, he wanted to power on his phone, and it wouldn't turn on. Only the led shows a blue light. It's impossible to turn the phone off, only by removing the battery.
I tried every option I could find
- Volume up + power button = same as just powering up, only the blue led light
- Volume down + power button = does nothing
- Volume up + home + power button = does nothing
I held every combination for over a minute.
I even tried to connect it to my PC and to get to it using adb commands. but my PC can't find the device.
I used a backup screen to make sure it wasn't just the screen that was broken, and this screen worked perfect on another Samsung S6.
My friend already has a new phone, but there are some pictures on this S6 that have some emotional value to him (pictures of deceased pets for example)
Does anyone have any idea what options I got left?
Or is this phone completely dead?
Thanks in advance
Strange. Seems like you have a damaged partition. Do you see a boot logo when powering on?
e.g.

Samsung
Galaxy S6 (edge)

Let's start with the simplest.
I hope you tried to:
(1) completely turn off
(2) press and hold vol down + home + pwr.
As you can't get into recovery/download mode, why not try a simple usb jig made with a resistor? This method will turn your phone into download mode again. You may want to use odin to flash a custom recovery and then backup your data.
Here is a short clip on how to use jig:

Soldering and recovering data stored on the nand chip can be a dangerous undertaking. It's advisable to take your phone to a data recovery specialist if needed.
Good luck
Thanks.
I indeed tried to power off the Phonehouse and using the "hold vol down + home + pwr".
I ordered a USB jig on eBay (I'm not the best in soldering, don't have a steady hand).
I'll try it, and hope it works.
Hi all.
I was charging my OP7Pro (Android 10 with TWRP) when the screen went white. I tried to reboot it (volume down + power) but it did not and eventually it turned into this (pls see image).
Whether I press power + volume up or power+ volume up + volume down, the screen becomes blank for a second then goes back to this. Power button and power+volume down does nothing.
Most instructions I see here ask for the phone to be turned off but I can’t turn it off. It went off when the battery was empty but I can't charge it anymore and connecting to a PC does not do anything.
Any help regarding this?
Thanks in advance!
