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!

Bricked (?) phone

I have Cyanogenmod 11 on my LG G2 and everything was working fine until I plugged my phone in to charge it earlier today.
Now it's stuck at a firmware update screen and no matter what I do (even trying to boot into my sideloader) doesn't work anymore.
Funny thing is, it booted normally into Cyanogenmod a few hours ago, but now the problem is back. Any help please?

You can manually reboot into recovery using volume down+power button. Holding the power button forces a reboot, so hold the combination keys after it reboots. The phone should show a white screen that asks about factory reset, ignore and follow the instructions listed then recovery will boot.

Cant reboot or boot normaly. only via bootloader menu

My nexus 4 wont turn on via the power button, nothing happens. When rebooting from the os it does not boot either, only turns off.
I can boot into the bootloader menu with vol down + power and boot into the os or recovery from there.

Is your bootloader unlocked? Do you run a custom Rom/kernel? Have you recently installed something new, like a mod or new rom/kernel?

Yes. Unlocked bootloader. CM12.1 with kernel and multirom installed. Battery have been replaced. I did not do anything at the time it stopped working.
I think battery was low and now I cant start it at all and it wont charge. When connected to a computer I can get into download mode.
I have had similar problems twice before when the phone would not boot.
First time a few years ago I found a flash tool on some gsm forum that I used to flash a file and it solved it. I cant find that thread.
Second time I left it in charger for hours and it booted after that.

i highly doubt its the battery causing the issue.are u sure the new battery was OEM battery?

I'm also in the softbricked state of routing the Sprint V20 in the dirtysanta way. The phone system will not boot, and it will continue to twrp. I installed the LS997 rom and superSU on twrp but it is not installed and only twrp will boot. Have you found a solution?

I battled this for hours and hours yesterday.
Pull the battery for a few seconds then replace it.
Hold volume down and power button at the same time. As soon as you see the LG logo - release and repress the buttons. Continue holding them until the factory reset screen comes up.
Push volume down to move to yes - then push power button to select.
Repeat above line a second time. Don't worry. If you have TWRP recovery installed it will not reset.
If you don't get the button push right and end up back in TWRP recovery without seeing the factory reset screens - just pull battery and try again.
Once you go through the 2 factory reset screens - it will bring you back to twrp recovery one last time but will remove the looping into recovery.
In TWRP Select reboot - system and it should load normally now.
It will take a while and you will be stuck on static screen. Try tapping the power button just to turn screen off. If screen turns off - lay phone face down to block light from entering sensor by front facing camera for a few seconds then tap power button to turn screen back on.
If after 15 to 20 minutes it doesn't load. Pull battery and replace. Push power button and it should load this time assuming you wiped and flashed a rom properly.

I just rooted and flashed using this method and all appears to be well. @midmadn are you saying I can expect to be in the static screen for up to 20min?

Possibly on first boot. I usually give it 10 to 15 then pull the battery. It has always booted after the battery pull and in a short amount of time. Maybe a few minutes.

Usually you can hear the boot sound or when screen turns off then cover sensor and press power all good.... You may hear the woman talking also after boot to set up handicap or something

Random reboots and now black screen

Hey guys my wife's S7 edge (SM-G935W8, Canadian variant) started rebooting and boot looping for a few days until it suddenly rebooted and stayed on with a black screen and the notification LED stayed blue until the battery died. Even holding home, power and volume down didn't do anything...
The phone was never rooted and completely stock. I just tried reinstalling stock firmware with Odin and everything went well as I got a pass but it still won't boot and gets stuck with black screen and blue LED.
Does this sound like a dead phone? I can't get into stock recovery, only download mode once the battery dies.
Just wondering if it's fixable.
Thanks

As the device switched off press the Power Button together with the Volume Button down, when the device vibrates, release the Power button and only keep the volume down button until the device starts up to the start screen appear.

Hey sorry for the late reply... I did try that. I can't even force a reboot when it's stuck.

You can enter download mode right ?
why don't you try installing TWRP recovery with ODIN
Go to TWRP website... and find your device
download .img.tar file
open odin and insert this file in AP tab and in the option tab (disable "auto reboot" )
( plug your phone via usb to your PC.)
on the log it will show (added)
hit start
once installed...press and hold vol down + home +power key (while it restarts) press and hold vol up + home+power key
You will now enter TWRP Recovery...swipe to allow modifications
wipe - > advanced wipe -> except sd card...select everything and wipe them (all your data will be gone)
now install any custom rom from this site..

I didn't try TWRP but I did try stock firmware from Samsung and Odin, said it passed but I couldn't boot the phone... Doesn't OEM unlock have to be checked in order to install TWRP tho? This phone was completely stock and never rooted.

yes i know but have you tried it ? i thought advanced wipe might help as it will remove everything.

My S7 edge is also having similar issue. It just died 4 days ago at 5 percent battery and red LED kept blinking. I tried to hard reboot using Power + Vol Down, it didn't work. I couldn't get into the Download mode either. It doesn't charge when connected to the charger, not detected on any computer as well. Any thoughts?

I plugged it in last night, after the battery was completely drained. It's been a week since the issue.
It was fine till this morning. I inserted the SIM cards and then connected to the laptop. I thought I would backup the data using smart switch before doing a factory reset. The backup went fine till 75% and then boom again turned off. This time there's a lot of battery left, and I might have to wait 4-5 days before it can be drained completely. But I'm now hopeful that it'll eventually turn on and when it does I'll immediately do a factory reset before doing anything else. I'm suspecting that a rogue app might be causing it. This time it might have happened while that app is being backed up. The LED is constant Red this time indicating the state it was connected to the laptop at the time of incident.

It turned on again last night when I connected the charger. It was showing the charging symbol. After 5-6 minutes of charge I tried to hold Vol - + Power buttons briefly to reset the device and it went off again. It's lying like a brick currently.

No sign of life again!
