S6 G920f wont charge properly and wont boot into recovery or download - Galaxy S6 Q&A, Help & Troubleshooting

hi i have a S6 G920f wont charge properly and wont boot into recovery or download.
there was no damage or liquid prior to this,
when i put phone on charge there is no light however screen turns on and show lightning bolt symbol and goes on and off every 10-15 secs.

Infuse keeps flashing the Samsung Logo

Ok, my phone was working just fine and then it randomly shut down on me and then booted up to the Samsung logo screen. The phone would flash the logo for a few seconds, go black, and then does it again. I've pulled the battery out and once I put the battery back in, the phone automatically turns back on without me having to hold down the power button or anything. I can't seem to be able to enter download mode or be able to reset it either. When I plug it into my computer it does display the battery icon charging which stops the blinking but thats it. Can someone help?

Could be your power button...manual issue...you know like it's stuck down. Go on YouTube they have a dismantling video on cleaning inside of phone buttons etc. Did it myself not hard at all

S7 won't boot, blue LED always on.

Just some minutes ago my S7 froze because of Focus Gallery App. I don't exactly know what it did but the phone did not respond any more.
So pressing the power button did not bring back the phone either. After searching for a bit I found a way to simulate a bettery disconnect by pressing Volume Down + Power Button.
The Phone came back up and displayed the initial boot logo. Also the blue LED is on. But nothing happens from here on. I do not come to the "Samsung" boot animation and the phone simply
does nothing. Retriying Volume Down + Power Button doesn't seem to help too. I tryed all button combinations but nothing brings the phone back.
I also cannot enter the recovery menu. So no chance to reset to default settings.
I am running a stock Android on the phone. Nothing was done by me. No custom ROM, no root, just plain Samsung Android.
Is there sill something I can do?
Edit: I just got into whats seems to be ODIN Mode??? Can I do something from here?
Oddly this happened to me last night although I may have inadvertently done it. But the only way I was able to get my phone functioning again was reflashing the OS to the phone.
How did you manage to get the phone into Odin mode? I'm having the same issue with the phone being totally unresponsive but the blue LED on.
if you can reboot your phone with the VOL Down/Power, when the screen goes black, quickly press and hold VOL Up, Home and Power. it should enter recovery. or hold Vol down, Home and Power to enter the download screen.
I have the S7 Edge (rooted, custom ROM) and it's running fine. My girlfriend's regular S7 is having the same issue though.
When she plugged it in to charge last night, she checked it a few minutes later at which point the phone had (started to) reboot. The blue notification LED was on and the screen had frozen at the 'SA' from the 'SAMSUNG' startup logo. Forced a reboot with down+power, resulting in just the blue LED (no logo this time). Phone was unresponsive (couldn't force a reboot again) so left the battery to drain overnight. The phone is completely dead today even after charging - no LED, no boot, no anything.
I'm not sure if she had the phone scheduled to perform an update overnight and it froze halfway through, but that would be my first guess. So far, no fix.

Samsung Galaxy tap 2 (10.1) won't boot up

Hello,
I have a Samsung galaxy tab 2 tablet that suddenly stopped working randomly when it drained power
I tried accessing the recovery menu on it but it dosen't work
When i plug it in to charge the charging animation appears until i press the power button to turn it on and the screen goes black completely until I restart it by holding the power button again and the charging animation starts again
It's also interesting to note that when it's not charging the boot logo appears for a few seconds when turning it on then the screen goes black completly until i force restart it,
is there a way to fix this without losing my data on it? (The files on it is very important)
if not, is there a way to extract my files out of my tablet while it's in this condition?
thank you for reading and i hope we find an answer soon to this.

Samsung S7 Stuck on Downloading Screen...

It is a samsung S7 smg930f stock Rom from Brazil, did not suffer any damage at all, but does not turn on anymore.
Does not respond to Power Vol+ Home buttons.
After some time charging it enters the Green 'Downloading do not turn off target' Screen on its own,
then you can reset it with Power Vol+ Home buttons but the screen goes black again,
it does not enter the recovery menu.
When it enters Download Green Screen I connect it to windows 8 and it shows 'Serial Gadget' under device manager.
I suspect Samsung killed it with an update during the night. Is there anything I can do?
Thanks
Celso

Question Boot issue - not powering on and unable to reach recovery mode

Hi,
I own an S22 ultra Exyonos 128gb and i'm having severe issues.
I was using the device (chrome) and it suddenly froze, and powered off. I powered back on, and it almost immediately powered off again. Since then ive been unable to power on.
I've tried force restarting, plugging into a PC with a usb-c cable and holding down volume up and power for 5-10 secs, but nothing happens. The phone simply gets stuck on the Samsung logo screen, sometimes the basic "Samsung" screen, and sometimes the "Samsung S22 ultra 5g secured by knox" screen.
Also when trying to charge with a cable, no animation to show charging pops up, ive not tried wireless charging yet.
Any idea how I can boot into recovery mode
If vol up + power doesnt work?
Thanks in advance
Can you boot into download mode (cable unplugged and device off press Vol Up and Down together and plug in cable) ? What is the screen showing after you agree to enter download mode ?
Is your device rooted or else modified in any way ? Did you do anything special prior to this behaviour ?
Hi s3axel,
thanks for replying.
yes, I can access download mode, it comes up with a Warning page saying "A custom OS can cause critical problems in phone and installed application. if you want to download a custom OS, press the volume up key"
No, the phone isn't rooted.
Nothing out of the ordinary was being done, I was just on google chrome browsing Reddit, when all of a sudden it froze, wouldn't respond to touch or power/wake button presses, and then crashed, and hasn't been able to boot u since.
I did have issues with the phone previously randomly crashing and then restarting and thought it could be malware. I booted into safe mode to see if it occurred again and if so an app could be the cause, but it didn't. I then booted normally and ran a virus scan with Samsungs in-built anti-virus software and then again with Malwarebytes, but nothing was found. it happened a few more times before stopping after a software update, so I thought nothing more of the issue until now.
