HELP! My phone turns off and wont turn back on...

When the phone is charging, this is not a problem...it only happens when its unplugged. If I put the screen to sleep or the phone goes to sleep on its own, the phone completely turns off and will not turn back on unless I pull out and replace the battery or reboot in recovery mode. This just started happening today. My phone is rooted so I unrooted and re-rooted it without any luck. I also tried different roms, but it still happens. Right now I'm on Unnamed.
Any help would be greatly appreciated. I did read about the sleep of death issues on some other phones...but in my case the phone is off and doesn't work at all (in the other threads I read the phone was still working even though the screen went black).
Thanks in advance!

That's exactly what it was. On my Evo 4g I used to set the screen off profile to 200-200 powersave...I tried the same with my E4GT and it didn't work so well. I bumped it up to 500-500 and its been working fine.
Thanks guys!

GN turned off and won't turn back on

Weirdest thing happened today, I was on a phone call and it just turned off. Wouldn't turn back on after it. When I plug it into my computer it shows up as OMAPxxx, and makes a bunch of connecting and disconnecting sounds.
I know there is a thread somewhere for this but since this happened out of no where i'm starting to panic... I've searched for it but couldn't find it so I decided I might as well post this since maybe one of you know the link to the thread or know how to fix it.

UPDATE: I pulled the battery and then held vol +\- + power button and then putting the battery back in, I was able to get into the bootloader.
UPDATE: Everything seems to be working fine now, which is weird as hell. Only thing I could think of was that I was using this app called talkatone to call my phone and it just died. I've had no previous problems with this phone at all which is why I got scared that something bad happened.

I was going to recommend the battery pull. Glad you got it resolved.

S III sgh-i747 turned off and wont turn on URGENT

i apologize if this has been solved but i am on a very tight time frame as i need this phone for work and cant spend any longer searching. my phone randomly turned off by itself this morning and will not turn back on. it gets to the samsung splash screen and the screen just goes black and the phone wont do anything, its like the screen is stuck off, i have to take the battery out to make it turn do anything at all again. it was stock this morning, never been rooted or anything, i just rooted it about an hour ago and installed twrp and flashed jedi invasion 5 on it in hopes it would help. now it gets past the splash screen and to the initial setup screen but it only stays on it for about 3 seconds before the screen goes black again and i have to take the battery out for it to do anything again. im not an expert by any means but i have flashed note 2's and played with them a bit and know my way arround them for the most part. any help would be EXTREMELY appreciated.
almost forgot to mention, in download mode it says qualcomm secureboot: enable
not sure if that means anything but i didnt get any errors while flashing or anything
thanks everyone

I would make sure you have to correct drivers installed for the phone on your computer and ODIN back to stock. You can give that a try and see if it helps.

I'll check that out when I get home but I'm pretty sure everything is right, it was doing it before I even flashed anything so I think something else is the problem

Faulty battery or power button. You can try ODIN back to stock, not likely it will help.

It's not a battery or power button problem. Before I rooted it if I took the battery out and turned it on again it would turn on fine if I kept the screen from turning off. and the battery was staying charged, and if it wer a power button problem why would it work to turn the phone on but not again after its on?

My vote is a faulty power button. Has been known to happen on the S3. Could be power issues though. Bad battery could be the culprit. If flashing stock does not work see if you can get a battery to test out.

ok so i flashed stock and it fixed it temporarily. after i flashed it it was working great so i decided to root it and flash jedi. so i did this and it still worked great. (at this point i should mention that the sim card in the phone has been deactivated this whole time) so since its working i activate the simcard, restart the phone, and the problem started again. so i took the sim card right out and turned it back on and it works perfectly fine without the sim card in... what do you guys figure? should i try a new sim card? has anyone ever herd of this happening before?
EDIT: tried my other sim card in it and it doesn't work either, so it snot the simcard itself

Bump

s2 bricked it self?

I've been using my S2 as a music player for a while. and its been running Liquidsmooth 2.10. and its worked just fine for ages.
my s4 was damaged, so i was using my s2 as a backup. it worked fine for a week or more, then suddenly one day, it just just killed it self. nothing was changed as far as rom/kernel or anything. i was just typing a text and all of a sudden the screen flickered, and the camera flash went off a couple times, the screen turned back on and the off again. then it just turned off.
i have not been able to get it back on since. it will show the SII logo for a few seconds then turns off. then proceeds to vibrate once every 2 seconds endlessly. thats all i can get out of it. it wont go into download mode or recovery or anything because as soon as i put the battery in, it tries to boot itself.
anybody have any ideas what is goin on here?

Sounds like the power button may be stuck which is a known issue with this phone. Here is a thread on the issue:

I've come to find out if the phone crashes this will happen, it's normal behavior believe it or not. If you will be patient and wait for about 7 to 10 minutes, the phone will finally reboot. The next reboot will be normal time again. This might be the device's way of protection, IDK.

thanks, this did the trick. but i think it may have been more so the volume up button. there is a metal piece that surrounds the volume button on the board, somehow it was coming off, pushed it back on and mashed the buttons a bunch, came right on.

This is almost certainly caused by a bad/stuck power (on/off) switch. It's a very common problem on all the US-carrier Galaxy S2 models. (Sprint, Boost, Virgin, Telus, T-Mobile, AT&T, etc. I don't think Verizon sold the SII)
You can check the switch by gently touching the physical switch (plastic cover/"button" removed) with a toothpick/pen/etc. As a "snap-action" switch, it shouldn't activate until you hear/feel it "snap" closed. If it's activating with a light/slight/tiny touch, the switch is bad. On my Sprint GS2, even the slightest brush against the power button caused it to wake the phone. Sometimes it would stick "on", and then the phone would reboot. I bought a new switch, soldered it in, and have no problems since.
If you don't have insurance coverage and are out of warranty, you can replace the switch yourself. Several eBay sellers offer replacement power switches for the SGH-T989 Galaxy S2. (about ten bucks)
Or, if you don't have mad soldering skills, several offer mail-in repair service as well, and most seem to have great feedback.

HTC desire 816 anoying turning off PLEASE HELP!!

Hi i have this supper anoying problem after 5.0.2 update! So basicaly What it does is when ever i will pick up the phone it would turn off like the screen would dim (not rebbot or shut down) and after a little tapping on a screen it would turn on again and sometimes when it does that it would glitch a little. While typing this it happened twice its sooooo anoying idk what to do now if i wont find any solutions i will just buy samsung galaxy or something like that. Also my carrier is Virgin Mobile thanks

Same problem, same phone.
Definitely annoying! Seems random but especially while rotating for me. I have not been able to dig up any solutions thus far.

Check out your proximity sensor settings in the HTC testing app, or try Gravity screen. Mine did the same thing a couple times, also clean off your screen at the very top left, if you look real good you can see the sensor just under the front camera hole in the glass, also sometimes a screen saver will mess with this sensor. One more thing is the stock lock screen can cause an issue similar to what you are talking about, hope one of these help yo out, cane0716

hi
thanks for information i already gave that phone to my friend and i think he fixed it by actually having different lock screen i currently have samsung galaxy s5 its wayyyy better lol

Phone turns off during use and will not complete boot unless plugged to charger even when the battery is almost full.
This error started last night after I did factory reset because of observed phone lag. I did mistakenly "wiped internal storage" but got the alert of "no OS during reboot", so I restored from my backup from SD.
the phone started properly but went off during initial setup and will go back off each time I tried turning it back on. I thought it was battery so I plugged it to power.
it did boot but will go back off once I have few touches on the screen.
I had to leave it plugged to setup my accounts else it will go off.
I'm using its Wi-Fi to send this message via my PC because any 2 - 3 touches will switch the phone off.
once it does that, it won’t even boot to bootloader before it goes off again unless plugged to power.
what I do to solve this please??
