I have an Epic 4G with a power button that will not respond, period. Phone is off and responds to the charger/usb cable being plugged in and all other keys cause the phone to "light up" when charging, but the power button istelf does nothing.
So, assuming the power button was bad, I ordered a new power button assy and installed it. It too will not work. There appears to be no physical damage to any of the ribbon cables, connectors, or boards inside the phone. The phone was Manufactured a month ago, so is fairly new and has gotten little use.
The phone's esn is bad, and my intentions were to flash it to cricket for a customer, so sending it Sprint is abviously not an option. Sending it to Samsung is also not an option since the phone has now been disassembled.
Is there any way to get the phone to "POWER ON" with any other button combination?
I have tried:
Plugging in USB Cable while holding 1 key: Does nothing
Holding VOL-DN + Camera + PWR while pluggin in USB: Does nothing
The phone only responds with the charging indicator (which the battery is now full).
Is there any other way to Force it into Download or Recovery Mode without a working power button?
Any help/advice would be greatly appreciated. Thanks!
I know a jig will work for download mode but I'm not too sure about recovery other than using rom manager to boot into recovery.... worst case senerio sell it for parts the screen etc etc.
I remember hearing someone using odin for turning the screen on search about it?
Would be really cool if you could remap the power button to something else but I know certain lockscreen apps or ROMs will allow for phone to be awaken by the camera button.

Hold 1 and then plug the phone in to USB. It will then boot into download mode. For recovery, hold vol down, camera, and then plug into USB.
Edit: just read that didn't work. Try taking out the SD card and battery and letting it sit for 2 hours then try again with the battery and SD out.

I was able to get it to boot up by plugging in the USB cable and unplugging it at the right time. But the phone doesn't respond to the slider, power button, or 2nd "click" of the camera button. However 1st click of the camera button and volume buttons work.
while playing around with it after about 10 mins the display switched itself to landscape mode and the keyboard backlight comes on, as if it has been "slid" open. If I slide it open and closed, it remains in that mode, as if it still thinks its slid open. However not all the keys on the keyboard are responding/working, but most are.

hmm, the problem isn't progressive, so it not getting better or worse. The only thing I can think of is a bad connection or the replacement Chinese cheap ass power button assembly is also bad.
the phone is only a month old.

When you get it to notice the keyboard slid open, pull the battery or turn it off then hold 1 and plug the phone in? That's my guess

I replaced the power button assy with the stock one from samsung knowing the power button is faulty, and got the phone to power back up jigging the usb cable in/out until the samsung logo appeared. The slide open/closed works perfect, and all other buttons and keyboard keys work fine as well (except the power button of course.)
This would leave me to believe the cheap chinese replacement board from ebay is bad to begin with. So ill have to order another one from a different seller/manufacturer.
I had installed the rooted UrbanPrecision X2 Gingerbread EI22 ROM with CWM Recvovery 5 before the power button failed a couple of weeks ago, and its working fine, but Id like to install the stock EC05 GB Rom to it through odin/recovery.
So my next question: Is there a way to emulate the power button with an app or something? Or enter Download/Recovery Mode from an app within the phone without using the power button?
Thanks again.
maybe this?
If worse comes to worse you can try this http://forum.xda-developers.com/showthread.php?t=1274999 which allows access to the most basic parts of the phone from what i understand. The only issue is you would have to use the ressurector every time to boot. also if you get it to boot with out this you can just use adb commands to boot into recovery and download mode if its powered on. The commands are adb reboot recovery, and adb reboot download
Wait that's right there's commands for download mode that you can put into the terminal emulator right?

i dont know how that would work, because they are adb commands, but he could try going into terminal emulator and simply typing reboot recovery or reboot download
Update Good thinking ac16313, just tested it. If he types su to get full system access reboot recovery definitely works( tested). Unfortunately download mode will not work though ( at least on cyanogenmod it just reboots). That would required adb reboot download via computer.
How could the Esn be bad if the phone was manufactured a month ago?

what happened
Have you found a solution, will it boot, and do the commands through terminal emulator or adb work?
I just got back from the sprint repair center where thankfully they told me there was an issue with there latest updates for the epic 4g with these symptoms. They downgraded the phone back to EC05 and now i have none of the symptoms anymore! Aside from feeling a bit sheepish for only trying to ODIN back to EL30 i'm very happy about the free fix! Fortunately it's my wife's phone so it's not too big a deal for it to remain downgraded. Hope this info helps somebody else!
My friend gave me his s2 to see if I can fix it.. The symptoms suggest the power button is stuck. But it can be pressed and it releases and can be pressed again, so it is not stuck as in jammed.
The battery is removed, and when the battery is replaced, the phone immediately tries to turn on. It vibrates and goes to the Samsung logo, then the screen goes black and continues to vibrate every 2-3 seconds.
I managed to get it to go to the boot anim a few times, but it froze and restarted. I also got it into recovery but it immediately restarted after that as well.
My only other thought is that the CPU isn't drawing enough power from the battery. What do you guys think?

You can try some of the things in this thread

It says it will work if it is stuck and not defective. Does stuck literally mean it is stuck in the housing and cant be pressed?

another thing i read some where on here is its sometimes actually not the power button itself but the ribbon itself to the power button that connects to the mother board sometimes becomes loose....try wiggling make sure its securely in there just worth a shot im sure anything helps right now
For some reason my phone will randomly turn off (or black out screen)/say it has 0% battery life and turn off, and when I press my power button it begins to turn on and show the ATT screen, but then shut off... and if I try to turn it back on the same thing happens. It seems that if I wait 10+ minutes it will turn back on "normally" but after a little while it does the same thing. What do you think is wrong with it?
Also if I plug in my charger to it, the phone doesn't have this problem.
I have been facing the same issue. Any luck with it?
Check your battery, if it's swollen you need to replace it. I had the same problem, replacing fixed it.

If you open the case and plug it in at the same time it will freeze your phone and the screen won't turn on. I'm guessing the only way to fix it is to restart the phone.
I tried it and it nothing happened. Though sometimes my screen dont turn on when i flip it open, i just press the power on button and it comes on orbaometimes it just takes a bit longer to come on, specially if it partially locked.

I can't reproduce the freeze. My screen always turns on.
i dropped my S4 and it broke the LCD/Digitizer. now for some reason it wont even turn on.
can anybody tell me if the device will not turn on if the screen is broke? when i hold the power button, it just vibrates once and thats it, no lights or anything.
or is it possible something on the inside has been damaged to cause it not to turn on?
i can get it replaced through my insurance, but id rather get the screen replaced if i can because there is a lot of sensitive data on there that i need to recover some how.
If you feel a vibration after pressing the power button the phone IS powering on. You just can't see anything due to the screen being broke. You can try connecting your phone to your computer via USB and hope that the MTP Application loads up so that you can view your Internal and External SD cards under Removable Drives on your computer. Try connecting your phone about a minute after you feel the vibration when pressing the power button. Hopefully the kind of data you are trying to recover is on either of the SD cards.

I think I know exactly what you're talking about OP. Does the phone vibrate quickly like it's going to power on then nothing happens? I broke a screen on my S4 and it wouldn't turn on. I just recently connected a good screen to my phone that was having the same issue as yours and it powered on immediately. So, I'm fairly sure the screen is the reason why your phone isn't turning on?

thanks, tried this.
my computer does see that the phone is connected. but MTP does not activate. could this be because i have a screen lock pattern?

I don't think the lock screen pattern should affect it, no. It usually boots up and displays the little USB icon in the top left as soon as its plugged in regardless of the phone being locked.
Stupid question but do you think the digitizer really is broken? You might be able to still draw the pattern for the lock screen and see if anything happens. Sorry this had to happen to you. Replacing the screen yourself might be the best bet. Or finding a service online. I'm sure it's easy to do.

I think the lock screen pattern does indeed affect it. I had a friend who broke her screen and was unable to access her files because of the pattern.
