[Q] Help ! phone wont turn on HTC ONE S

I wanted to install cynagoenmod so
1. I unlocked bootloader using HTC dev
2. I flashed cwm recovery
3. I flashed boot.img extracted from the cynagoenmod release
it was stuck in the boot-up at the HTC logo with the disclaimer text "this build is meant for developers....."
I had to run an errand so I left it as is.
when I got back it wouldn't turn on
wont blink the soft-keys after holding the power button for 10 seconds
wont boot into bootloader when holding both the vol- and power button
when connected to the charger the LED stays on orange for about a minute and turns off
only response it does a flash of white (like this like when u close the TV effect ) after holding the power button for 20 seconds
any advice would be welcome

Just keep holding the power button and also the volume down button for 20-30 seconds. It should pop into HBOOT.
If you see the screen flashing white that should mean it isn't hard bricked.

That's strange. Does your PC detect it when you connect via USB?
Plug it in and if nothing happens, press/hold all three buttons in different combinations and sequences and hopefully something should happen.

[Q] Can't turn on my phone?

Hi,
I think I bricked my phone. I tried to root it using this guide http://forum.xda-developers.com/showthread.php?t=1583427
I installed CWM recovery, but when I tried to boot into recovery the screen left saying "Entering recovery.... This build is for development purpouses only etc..." Same after few reboots holding power button for ~ 10 seconds.
So I left my phone on that screen during the night, thinking maybe it takes some time to enter recovery
But in the morning the phone was dead and I can't turn it on.
The screen blinks for a second (see video here http://www.youtube.com/watch?v=bI-gy-hhXq0&feature=youtu.be ) and thats it. Holding Power, Volume down + Power doesn't help.
Any solution for this?

when you plug your phone to a charger does the red light come on?
you need to get into bootloader again. Saw your video, but what happens when: while holding volume down you press the power button for a second (while still holding volume down until bootloader starts?

Sometimes it does, sometimes it only comes on when i hold the Power + Volume down and goes off when I release Power button, bur then comes on again after a couple of minutes...

So if I read you right, you can get into bootloader? Reflash recovery, then flash a Rom and fastboot a boot.img

No, I was talking about red light. The screen doesn't turn on at all, just a short flash.

I don't know man, maybe someone else will help out here. Hold power button for like 30 seconds. You might have to send it in to be repaired.

How to power on a phone with a broken power button?

My LG G2's power button and volume rockers appear to have stopped working. My phone is off and USB debugging is off. Is there any way I can power my phone on? Thanks!

Install some imaginary buttons from Google Play. Maybe it will help

The problem is that my phone is off! And I can't turn it on without using the power button it seems.

Is it the button itself that is broken or the functionality of the electronics? I once had to replace the physical button after the guts had fallen out of it. Got to the last step of rooting my phone, went to press that rocker button and ...nothing. I always used the virtual, on screen button for photos, so I never even realized that it was dead. They can usually find them somewhere online

I think it is the electronics because at one point my power button/volume buttons were randomly getting pressed without my input. But, I really don't know for sure.

Suddenly my phone Asus zenfone 5 got switched off while operating the phone and unable to power on using power buttons only.
I dont know what to do.
previously we have the option to remove the battery and place again. But here i am not having a chance.
so,
please guys help me.

Oh bro don't take panic. Don't know about methods to do this but I think power button is repaired in less than 2$ everywhere (all around the world)
Good luck

All phones have a recovery mode which can be accessed by pressing volume up or down (only one) while inserting the USB cable. This powers on the phone for download mode allowing you to restore software.
As mentioned best method is to repair the faulty button but I would try restoring STOCK image/rom first.

Possible solution
Hope that this trick could help someone.
Situation:
- broken power button
- lg g2 off
- WORKING volume button
After lots of tries to power on that damned phone something happens:
1) Charge g2 until 100%.
2) Hold both volume button (UP AND DOWN) and insert power supply
3) be ready to disconnect the power supply immediatly when the lg logo appears
4) disconnect charger (Screen will goes off) keep holding volume button
5) reinsert power supply and when screen goes on release and rehold again both volume button.
And... Magically lg g2 starts!
I really don't know why this procedure works but i currently use this trick to power on the device when accidentally my lg goes to 0% -.-'
Some advice:
Before doing all this combination i've tried holding both volume button when the device was off.. For some reason the red led (charging color) flashed five times then this trick works. Don't know if was just a coincidence. But triying can't do any damage!
So... HOLD FOR MORE TIME YOU CAN THOSE ****** BUTTON.
And pray.
Hope that this will help someone

this worked for me. although I found that I did not have to reinsert the power supply nor did I have to rehold both volume buttons again at the end.
so 5) when screen comes on, release the two volume buttons.

Install Volume unlock, it'll make your volume button unlock the screen

Use ADB Commands to first connect your phone with your pc using a terminal and then use some other adb commands to power it on.
Google for some ADB commands.
Hit thanks

Lg g2 D802 here, non-responding power button. I power on my Phone just by plugging in the power cable and pulling it out when the logo appears. Nothing else. Screen on/off by knock-on funktion.

Please help me study

I own a redmi 5a and I use it for my studies. That phone is one of the two smartphones that we have in our family. Because of it being old, the battery didn't hold the charge well so I got it changes maybe 5-6 days ago.. Today, all of a sudden, while I was in the middle of solving a model question paper, it stopped working. The screen went totally black. Now when I press the power button, only the notification light blinks and nothing else happens. I tried keeping it pushed for maybe 1 minute as well but only notifications light keeps blinking. I tried pressing volume up+power button, volume down+power button, volume up+volume down+power button but nothing happens. Only notifications light is blinking. It does not blink when I don't press any button. And it does not blink when I don't press the power button. Can anyone please help me and tell me what to do? If this phone stays like this I will not be able to study. I really want to do good in my exam.

Get the orignal battery back, connect the device with cable to charge, and then try to power on it. Good luck to you.
