Non responsive fastboot and power button!!

Ok so, I was going to flash CM 9 v1 on my device, and when i was in clockworkmod recovery I noticed that the power button wasn't working at all.
I took out the battery and put it back and then it reboot itself and got stuck on the unlocked padlock screen.
Then i managed to boot it by pressing vol up and down at the same time and putting the battery in when plugged on the computer with the usb cable. This is the only way i can boot it. And after it runs a while it crashes and reboot into the unlocked padlock again. And this over and over.
Then I tried to go to recovery to reflash with the soft sensitive buttons and the fastboot screen doesn't do anything at all. If I press vol up or down to move around it gets stuck.
Got it to work a while and reverted back to stock rom with rom manager to see if fastboot worked again but nothing happened.
I need help to fix this.
I try to go to download mode but it doesn't work either. ADB works tho
Any suggestion??
(sorry fot the bad english)

i actually had the exact same issue a few weeks ago
it was an issue with the power button itself since i got everything back to stock and the power button still wasnt working properly
i had to send it to samsung repair center
they fixed it for free and it turns out the issue was indeed the power button

thank you for your answer!
i will send it to samsung!

My rooted sph-l720 will not boot!! Please help!!

I rooted with CF-auto method, phone worked fine. I downloaded CWM Rom Manager and downloaded CWM Recovery through the app. I decided to try and flash TRiforce 5.4 as my first ROM. Selected to back up everything and wipe clean with a full install. Towards the end There was a fatal error. It said it needed to be rebooted. I clicked reboot now. It said something about AROMA installer. Then rebooted. It showed the Galaxy s4 logo, then went black. I waited and waited and waited. And nothing happened. I tried pressing power and nothing would happen. I eventually pulled the battery out and reinserted. Upon pressing power, the same thing. It would show Galaxy s4 logo then go to black. I thought perhaps my battery died during install. Tried plugging in to A/C adapter and the battery logo pops up but the circle that usually continues to flow in a circle just freezes and does not flow. No light turns on to indicate charging. If I unplug the charger it is still frozen on the same charge screen. I popped my battery into a friends s4 and it charges fine, and is still at about 50% power. I've tried vol up+home+power, vol down+home+power and they both get the same results, just the galaxy s4 logo, then black screen. No booting whatsoever. Does this mean my phone is now bricked?:crying:
edit, vol down+ power has just gotten me into download mode! I guess I'll download a stock rom tomorrow and flash it via odin. Sucks because i don't have internet at my house. I'm at the library right now... 15 hours to dl stock rom lol...

What about volume up + power? if recovery boots you can try to flash in that otherwise you are stuck trying to use odin

Try going into recovery mode again by pressing get down the volume down and home button than finally the power button. The phone should vibrate and then as soon as the Samsung logo comes out let go of the buttons or else the phone will reboot again. Time it right so it goes into recovery

Have you fixed this issue, volume up +home+power is recovery mode, volume down+home+power is to download mode then u press up to complete

Rezzing old thread, I know. But I'm leaving this here in case anyone is poking around for clues to their s4 not powering on.
I have one that does not power on, as in bo combination of "press this and that..." is going to work (as if that isnt the first step in troubleshooting...I know not everyone does it right, but its really annoying when any post mentioning no power on/not responding to any key presses or charger plugin is full of "just try harder to boot it" posts..... Anyways...) The power pins register about half a volt, surging around from 100mV to ~3V . The battery does not charge and there us a constant slowly draining voltage on the power pins while unplugged and no battery.
The only clue Ive found so far us a youtube video of a no power on S4 having its power IC replaced which fixed it. Unfortunately I dont have the tools currently to try it, so at least mine, is still dead in the water.....

GT-i9500 boot loop with a difference

So I have a GT-i9500, its a year old and it started with a little problem.
A few months ago it got stuck in a boot loop, the one where it gets stuck on the Galaxy S4 logo. I pushed the power button a few times and it booted properly.
Well its now stuck in that boot loop again and no matter the amount of times I play with the power button I can't get it out of the boot loop.
I have tried everything.
Here are some of the issues:
If I put the battery in the phone boots automatically.
If I try the POWER + VOL DOWN + HOME combo I get into the download mode but then it restarts and goes back into the boot loop
I can't put it into recovery mode, it just fails to respond to the POWER + VOL UP + Home combination.
I have tried different batteries, I've left the phone without a battery for days to see if it would fix the issue. Nothing works.
Any suggestions or insights?

Soft bricked my T280 and so confused!!

I recently updated my Samsung Galaxy Tab A T280 to the latest firmware and I lost my root. So this afternoon I re-rooted it. Or I attempted to, anyway. Everything seemingly went fine, and I booted into TWRP just fine. I went to flash the ROM and I also selected wipe cache/davlik cache to be done as well, and tapped reboot. My device then turned off and when it started the reboot, it got stuck on the Samsung Galaxy Tab A logo screen and would not move or power off by holding the power button (I tried for a LONG time by using a rubber band to hold it down so I didn't have to, with no luck), and every other combination of buttons wouldn't do a thing, except for holding power + vol down, which made it turn off and back on, but it wouldn't finish rebooting and it just got stuck at the Samsung Galaxy Tab A logo again. So then I thought that maybe plugging it into a charger might not be a bad idea, and after holding down power + vol down again, it turned off and turned on and showed a battery with a charging symbol. I've had it plugged in for an hour and it does not show a charge or do anything except for go back to that boot logo if I unplug it from the charger and again hold down power and volume down separately.
I know it's not hard bricked because it is somewhat responsive so I think there's a chance to fix it, hopefully. I just want it to turn on and fully reboot into anything or in any way that will allow me to be able to fix the issue. My computer will not recognize the device so ADB is not an option right now unless I'm wrong.
Thanks a lot guys, I am so confused and could really use some advice.

What firmware did you install

Try to install original firmware via software "Samsung Smart Switch" on your PC with connected tablet.

I too recommend that you try installing the last firmware that you were on via Odin. Also, when you hit that screen lock issue after a firmware flash, where only the Samsung logo appears do this:
1. press and hold Home + volume up and volume down along with power button (that's all 4 buttons). Hold it there for at least 20 seconds and it should power off.
2. Once the device powers off keep holding the buttons but let go of the volume down button.
3. Once the tablet starts to power back up again release the power button and then in about 1 to 2 second release the rest of the buttons.
This should get you back into recovery. You should at least be able to restore any backup, that you should have already, on your external micro SD.
Good luck.. : )
"Chance Favors the Prepared"

the above post is 100% right. Reboot back into recovery and you'll be good to go. Also twrp has a option to reboot back to recovery so this doesn't happen, just a fyi for future knowledge. Best of luck..

You tried to flash a rom with twrp?
You need to flash stock firmware with odin.

Phone bricked... Totally...

Hello all. Since nougat update my phone has started having boot up issues. I had software update a month ago and after it was updated it failed to boot up. It just froze on Samsung logo screen and i had to wait for the battery to drain to start it again. So that time it started after a good few tries. Now last night it had another software update and again after it was finished it rebooted and failed to boot up. Gets stuck on logo screen/ samsung screen. I tried booting in safe mode.. nothing ... gets stuck again on black screen and have to wait for battery to drain. When it gets stuck i can't do anything not even reboot with any of the buttons. I've tried going into recovery mode but once it boots in recovery it shows Installing System Update or something simmilar and in 1 second gets stuck untill battery is drained again. So basically i can't do anything on it. It won't boot up in normal/safe mode or recovery mode... Any suggestions ? I've tried samsung switch on my PC but it needs the phone into recovery mode and i can't get this far. What else is there to do ?
I managed to get it into download mode and flash a new stock firmware... It installed without error and when the phone boot and apply the updates then rebooted again and still go stuck after Galaxy S7 Edge Logo. Got past that and froze on the SAMSUNG logo. After that just blue LED and black screen... Can't switch it off now , gotta wait for it to drain the battery...

It doesn't work. Once it gets stuck nothing works. I've tried everything.
It just freezes completely... Vol Down + Power doesn't work either when it freezes...
Wish they made phones like before so you can just take the battery out...
