[Q] Phone continues to reboot, need help

Alright so here's the issue. I was about to flash the latest CM using ClockworkMod, before it restarted it asked for superuser permissions which I had already granted before which seemed odd to me. I set down my phone after this to let it do its thing after this and when I picked it back up it was off and wouldn't come back to life. It's bricked.
When I try to power it on, it shows the Samsung logo and then goes black and then nothing. If I hold down the vol+, power and home to get to recovery it will show the Samsung Galaxy S3 logo then goes black, then shows the samsung logo again, then goes black and stays there. If I do vol-, power and home, it asks to press vol+ or vol-, so I press vol+ to get to Odin. It shows the Odin screen for about 5 seconds and then it goes black and stays black.
So basically, I can't boot, get to recovery, or get to odin long enough to actually use it. Any help is appreciated, thanks.

Sounds like it is time for a replacement. I had a Thunderbolt that did the same thing and couldn't fix it because the phone will not stay on long enough to do anything.

[Q] Samsung Logo Splash Screen and Keeps rebooting

Hi,
Two days ago I got the official update of jelly bean 4.3 to my Samsung galaxy s3.Last night phone was dropped with in small height. Today morning I switched on the phone its worked fine. But at the evening suddenly my phone was restarted and Samsung Logo Splash Screen (Samsung galaxy S3 GT-I9300T) and Keeps rebooting. So I remove the battery and insert it after a few second. After that the phone worked fine and again the same problem happened.
if I remove the battery, phone switch off. And if I insert the battery again, phone switch on itself (without press power button) and keep restarting.
I try to open the (Home + Volume Up+ power ON) button option. But is not working. If I plug the phone to charge, gray battery shows and again restarting to charge…. (I mean, phone won’t stay in a stage).
If i try (HOme + voulme down + power On) option, phone shows the download mode for 5 seconds and restart again.
So can you please let me know it’s a software problem or hardware problem?
If it’s a software how fix it ? ( I tried the emergency firmware recovery through kies, but kies couldn’t fine my phone).
Thank You.

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.

S6 G920f wont charge properly and wont boot into recovery or download

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.
The phone does not actually show it charging but if i leave it connected the phone warms up and charges.
I can power on phone to the samsung s6 logo where it gets stuck and resets.
I am unable to boot into recovery or download mode, and volume buttons seem to work as i can reset phone by using vol down and power button.
any have any ideas what the problem could be?

Galaxy s6, boot loop from HELL

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.
