Hey guys, wondering if this great site can help me out. Just got a phone off of eBay (White HTC Evo 4G) However when I plug the phone into charger(s) it doesn't light up, display any LEDs whatsoever. furthermore if I try to power on the device it does the usual display of the HTC EVO 4G Logo on the whitebackground but then the screen quickly shuts off.
I then try the power+vol up key to access recovery menu. It will finally display the menu BUT THEN quickly the screen shuts off.
I then try hard reset, holding power button + vol down button. Same thing, menu pops up, as soon as it does the screen shuts off.
Connecting via USB cable of course windows does not detect it, it wont even boot up for that matter period via this method. lol. Any suggestions?
Send it back .... fast.

<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!!
I went to plug in my one x to charge. The second that I plugged it in, the screen went black. The home and back keys were still lit up. I'm not sure if it auto restarted or I powered it down. After that it seemed like it was just going to restart, but it only got to the htc logo screen. The normal little orange bar showed loading. I think it only does that once normally, now it goes twice. When it finishes that animation, it just sits at the white htc screen.
I haven't modified anything recently. It has been running over a year with no changes. If I hold power down at the screen, the home keys flash every few seconds. After seven flashes, the phone powers down and immediately restarts. There is no way to power it down until it dies. I took it apart and removed the battery for a few minutes, that didn't help at all.
If I home power and volume down, the red charge light comes on a few seconds. It then seems to boot to a black screen. I can't see anything, but the home keys are lit up. If I hold power down a while, it goes back to booting to the white logo screen. I tried hooking it to my computer, but it isn't getting to a point where it is being recognized as being plugged in.
I assume the thing is beyond help, but any suggestions would be greatly appreciated.

"home power and volume down"?
If you mean HOLD power and volume down, trying to get to bootloader, and you cannot, you're not going to be able to do anything else with and to your phone I am afraid.
If you ARE holding down the Home key in the process, I am not sure if it makes a difference but don't.
thanks

Sorry, you are correct, it should have said hold. I tried to edit it, but it wouldn't let me edit so soon after posting as a new member. My phone has been through a lot. In the process of opening the case many times, the volume bar got damaged. I have to use something metal against volume down to manually trigger it. I'm fairly certain that it has tried to boot into the loader though. I guess the charger had a short and fried some memory..
Here is the series of events. Upgraded to LG optimus G one week ago and that same day, rooted it and installed Cyanogen 10.1. Week goes by functioning completely normal. Today, the battery was down to 5%. Powered off the phone and hooked it to my PC via micro USB cable. Return an hour later to turn it back on. LQ logo appears for a split second then the screen goes dark though still active because of the backlight. Only response I get is when holding down the power button until the screen goes off. It then powers back up and briefly shows the LG logo and the screen is blank again. No response from any other attempt to boot the phone into recovery mode or normal.
Simultaneous power and volume down does not enter recovery mode, nor does any other combination of keys

Are you holding down the power button while still plugged in? In essentially the exact same scenario you are experiencing, my phone will not turn back on if I have it plugged in.
Unplug it, hold down the button until LG logo appears and release while LG logo still on the screen. That's how I have to do it.

Its not going to charge with the battery that low on the computer. you need to power it off (vol down + power) and plug it into the wall charger. leave it for 30 min. unit should turn on at this point. if not read the repair guide in this thread or jump on the irc and myself or some of the other people can help you.

The USB port I was plugged into was a 3.0 which has extra power sent through it via a bios setting specifically to charge phones. Anyway, I disconnected it and it is now connect to an adaptor from a wall outlet. We'll see what happens in the next 30 min.
I had my phone sitting on my desk, pressed the power button to check the time, and set it on the desk again. Suddenly, I felt it start vibrating over and over and over, and when I pick it up to check what's going on, I see it's stuck on a restart loop. The phone turns on, the "HTC Quietly Brilliant" logo appears for about two seconds, and it turns off, again and again. The same thing happens with the phone connected to a charger, and if I press power+vol down when it's turning on, I get to the bootloader screen, and it shuts down again (can't scroll through the options using the vol keys). The phone is running on the stock ROM, and I did the OTA update like three months ago. Any thoughts on what's going on would be greatly appreciated.

your power button is stuck in press position try press it to release it
The button seems to be fine. It doesn't feel stuck, and has a normal clicky sound. I tapped on it, and wiggled it a bit, and the same thing keeps happening.

yes the button it self is ok but the back side is stuck try hit the phone near to power button with the hand to release it
Either the button is stuck or your power flex cable has malfunctioned. Power Flex Cable can be replaced and should solve this problem - see the below thread I made some time ago regarding this:
http://forum.xda-developers.com/showthread.php?t=2638916
My issue was water damage but would cover any damage to the power flex cable.
So this morning my Razer Phone was all fine until it suddenly vibrates twice then the screen goes blank while in my pocket. I once thought it was just ran out of battery so i left it charging for a moment. When i tried to turn it back on, the phone only vibrates once and the screen turns on but appears blank. Even the razer boot logo doesn't shows up. After few seconds the phone comes back turned off.
The charging port is fine so are the charging cable and the adapter. Power button, fingerprint, volume button are all working normally. I also can feel a little heat on the phone while charging just like usual. I think the hardware seems to be just fine. I've tried to get into the recovery mode by holding down power and volume up button for 7-15 seconds but didn't work. It only brings it into the 'blank screen' again like when i'm trying to boot it up before.
I don't know how could this happened all of sudden, i never did anything fancy to it apart from playing games, using apps and such.
Any help would be appreciated.
There maybe two reasons there is a bug with you droid or apps & services running tho or an app or a mod you installed corrupted your systen
did it reboot in recovery or fastboot
u can try to boot to bootloader on PC , turn off your phone then plug in PC by cable, hold volume down + power button to boot to bootloader .
