I have a Samsung galaxy s2 with broken power button.
I installed app which turns on the screen with volume buttons. And other icon to list of quick buttons on the bottom of home screen to turn off the screen. I have and notification in notification bar. ... just tap and screen is off.
Now. There is boot procedure without the need of power button.
You put micro usb cable. Wait. You get it out of phone. Immediately get battery out and return it inside back. Done. Phone power on.
I have android 4.1.2
I want to modify this boot procedure. This result is liked: when phone is powered off. .... I just connect usb cable and phone power on and after a minute I to can use it.
I want to bypass the moment when you get the battery out of the phone.
Any suggestions are welcome. Thanks.

<Quote>My epic 4g won't power on. If I plug in a usb cable/ac adapter it will charge the device. The screen comes on and shows the green battery and the amber LED turns on and then turns blue when it reaches 100% charge.
But the power button does nothing. It won't power it on. Is there anything else I can do to force it to turn on?</Quote>
So I got it to boot up. You can do this by holding the power button down while continuously unplugging and replugging in a power adapter (or usb cable). You may spend 2 or 3 minutes unplugging and replugging it in (you need to do this rapidly) but eventually you'll be greeted with the samsung boot screen. If it makes it to the battery display screen you're not unplugging and replugging in quickly enough.
Hopefully o that anyone else who encounters this problem can potentially use their phone in a pinch or recover data off one with a broken power button. My power button is definitely busted and I'll need to get it repaired by sprint unfortunately.
Thanks!

Did you try putting it into download mode? may need to ODIN back to stock.
Ok im new to this forum, as i just ditched my evo shift and picked up and epic, but you might try booting to another menu. Try unplugging it and holding the 1 key on the keyboard then press the power key. If that does nothing then id have to guess ur actual power button is broken. You could also try pulling the battery witih it unplugged for like 5 minutes then put it back in and hold the power button for like 20 seconds and letting it go.
Edit: He beat me to it
It appears the actual power button is broken, neither of those solutions worked. Is there any other way to force it to power up without use of the power button?

Thank you soo much! I have a messed up Epic that has to be sent back to Sprint but I had to get my work information off of it or I'd be in it deep. Your trick worked perfectly!!
So, I had to replace the screen on my phone because it was cracked. But not after putting it all back together, the phone just boots loops. I am trying to follow the guide about unbricking your phone but I am unsure about getting into download mode. I hold down both volume buttons and plug in the usb into the computer, but noting happens except the phone just keeps boot looping. How do you tell if phone is in download mode? What does the screen look like?
If you get into download mode, you can't miss it. It is pretty obvious. To get your phone into download mode, shut off your phone (Hold power button for 12 second), wait 2-3 sec, press both volume button and then insert usb cable.
Hmm. Seems like my problem is something else. I can't get in into download mode. I cant even get the phone ti turn on if it isn't plugged in.

Could your battery be dead? Getting to download screen is a bit tricky as far as the timing is concerned.
USB should be already inserted, otherwise phone will just boot when you plug the cable in.
So usb pluged in, next turn off the phone via power button, now hold both volume buttons + power, should work.

^this has been my experience as well. Turn phone off. Insert USB. Wait for charging screen to flash on and disappear. Then press and hold vol+ vol- power until Download Mode screen flashes on, then release buttons.
First of all when in download mode you'll see a box displayed saying "download mode" it's hard to miss even you try to.
Here's how I did it. Instead of trying to push both vol + and- , press the middle part of the volume rocker. And press power button at the same time. USB cable can be plugged in advance or can be inserted later on. Only advantage of plugging the USB later is it gives you a proper grip and reassurances you've pressed the button combination correctly. Note that the phone will look for a USB presence before booting to download mode..hope this helps

Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.
My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.
Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks
Your welcome let me know how it goes. Will do my best to help.
I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.
How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?
To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.
Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.
Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium
I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

Should it show any lights? It's as if it's not even charging at all.

If it was powered off I'd expect the battery icon to show.
Did you try holding POWER + VOL DOWN?

Yeah, tried to hold it down. No LED lights and nothing shows on the tablet. It's as if it's just dead.

There are no leds.
I know someone else had the same problem. They used a different charger and it worked.
Try that first.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.
Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.

Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.
That's the normal lollipop boot screen.
