[Q] Phone restarts and turns off - T-Mobile, Samsung Galaxy SIII

My tmobile galaxy s3 was turning on by itself as soon as i put the battery in it. The phone would stay on for about 5 seconds then turn off. This repeated itself over and over again as soon as i put in the battery in.
I took it in to get repaired and the guy told me its the power switch so he replaced it.
I rooted my phone and put a 4.3 rom on it. Everything started up fine and installed properly.
2 days later the same issues on it turning on by itself and turning off. I took it in to the same shop and they are blaming me for a bad root.
Any thoughts?

It could be a problem with the power button. I had a similar problem with my gs3 when I bought it used. If you take the battery out and then put the battery back in and the phone boots up by itself without touching the power button then it might be the same problem I had..
I don't recommend this fix for everyone with a power button problem but in my case it fixed it and it's been perfect ever since I did this..
I fixed mine by taking my phone apart and taking my dremel tool with a fine grinding wheel and sanding just a millimeter or two off of the face of the internal power button. The silver power button that you see on the outside of the phone is just a cover that presses on the internal button which is just a tiny micro switch. I found that the external button was always putting pressure on the internal button and causing the phone to constantly reboot. By sanding a bit off of the internal button it gave it some space so it wasn't always putting pressure on the button. There's a few video's on youtube that show how to take the phone apart to get to the power button. It's very easy.

[Q] GNexus Not Booting

Sorry if this question's been answered in another thread, I tried searching and couldn't find any question that exactly matched mine, or any response that solved the issue.
I purchased a used, unlocked Galaxy Nexus from ebay around a month or two ago, in near perfect condition -- this has been the first time I've had any problems with it. It's probably not applicable, but after the release of the dev preview for Ubuntu phone OS I rooted the phone and reinstalled the factory image "takju 4.2.2 (JDQ39)".
Anyway, a few hours ago I accidentally bumped my phone off of a counter in the kitchen onto the tile floor. I picked it up and looked it over, and noticed no visible damage whatsoever, although the plastic cover had been partially dislodged; however, the phone's screen was dark, and the phone was unresponsive. I took out the battery and replaced it, then held down the power button. The phone vibrated once, like it normally did when booting up, but the screen remained black and the phone unresponsive unless I removed and reinserted the cover again.
I've tried charging it, plugging it into my pc, removing both the battery pack and the SD card, taking the battery out and rebooting it while holding both power buttons down, but I still get no response (and my computer doesn't recognize the phone when I plug it in). After reading a post where someone had success reconnecting the display, I unscrewed and removed the casing, then disconnected and reconnected the display from the motherboard -- still nothing.
Is there anything else I can do, or is my phone beyond repair?
Did you check the other connections while you had the phone apart?

I opened it up again and took pictures, but I'm not very knowledgeable about this sort of thing, so I can't tell if anything's wrong or not. Should I remove the motherboard to get a better look at the display?
You're talking about the back cover which became dislodged upon impact? I'd say you're lucky that the phone still gives that vibrate. But it seems there are so many things that could go wrong from an impact. Do you have fastboot? [I know you said you tried holding down both volume buttons and power, but try pressing them first then tapping power.] If you don't have fastboot, then your only options would be omapflash and odin. If these do not work, it's gonna be hardware. Maybe the display is gone, if you get the vibrate but see nothing..

cell phone keeps vibrating will not turn on

hi. i got a tmobile samsung galaxy s2. I am out of my warranty. i had my phone for about six month thru a warranty exchange.
I was browsing espn.com, then out of no where the phone turned itself off and started to vibrate. I have tried to power it on, and it just vibrates. it turns on a quarter way then begins to vibrate. i left the battery out since the problem started waited the whole night to pass, still just beeps.
I googled how to put phone into discovery mode, but when I do the steps, it also powers the discovery mode quarter way then turns off and starts to vibrate. Is it a sticky power button. The power button presses normally,doesnt resist when i press it.

Sounds to me like a sticky or stuck power button. If you can take it apart...clean around the button that might help. There are a few guides in the Skyrocket forum on how to do it. Search for sticky power button or look at the stickies by Vincom. I have a T989 as well and used some of these methods and it worked. Good luck!

To be honest your probably going to have to the the button replaced I had same issue I tried everything to cleaning it and around it and even prying it away from the connector and nothing worked I had to send it into Samsung and they had to replace the motherboard thankfully it was still under warranty its worth a shot to call em n ask if yours is

I had the same issue, took it apart and tried cleaning to no avail. I called a local cell repair shop and as soon as I said I had an S2 and started to describe the issue, he stopped me and said it was a short in the switch, which had to be replaced, and gave me a quote. Seems to be something of a common issue.

How much was it for the shop to fix this?
I am looking at buying an S2 for $100 that is doing this shut off & vibrate.

I got something similar happening to a S2 I have. I was using it, it just shut down and won’t boot anymore. As soon as I plug it in it'll start vibrating indefinitely, pull the battery and re-insert it, and it'll keep on vibrating indefinitely. Sometimes I see the SAMSUNG logo but that as far as I can get. RECOVERY doesn’t work, ODIN doesn’t work, no button combination works... seems kind of dead to me.
You guys think it’s worth sending it to SAMSUNG and getting a quote to get it repaired?
EDIT: sometimes i can get into download mode for about 3 seconds then it blue screens and reboots. I can get as far as pressing the VOL+ up and then reboots...
So did anyone find a solution or was it a "short in the switch"?

SOLUTION !!! Hey i share your pain... i have an
S2 as well and have been facing the same
problem... my phone is rooted so at first i
thought the problem was due to an unstable
custom rom... anyway the REAL problem is
called a "STICKY POWER KEY". all you need is a
bright light, a can of CRC (the none conductive
type) and a Phillips head screw driver.. you need
to remove the back cover of your phone, remove
your battery and or charger , sim and sd card
then remove the six screws that is holding the
phone together. after that , carefully pry open the
phone and remove the circuit board that has the
power button and the volume Buttons.. this is a
little tricky because in order to get the circuit
board out you will need to detach some
connectors.. now you need to spray some CRC
on the power button using the fine tip straw that
comes with the CRC CAN .. then you just need
to press the power button until you get tired... i
use CRC intermittently while i press, be careful
not to get too much on the circuit board tho..
when you are done , put the phone back together
and let it sit for an hour then replace the battery
and turn on your phone voila ..... feel free to
inbox me if you require further assistance...

[Q] Desire wont start up. The screen just keeps flashing.

So i went out on a night out and my battery went flat whilst i was out. I come to start it after charging it up and it just keeps popping up with the start up screen for a split second and then going off. It keeps doing this until i unplug the charger or take the battery out. I managed to get into the reboot screen and tried starting it from there to no avail. The battery is only a couple of months old so that should be good.
I took it to a phone repair shop and they said the board was gone and that there was nothing that could be done with it. Is this the case?
I don't generally turn it off just keep charging when it gets below 20% battery life. I did however install solitaire since i last powered it down if this might have any influence on the situation.
Check if you can get into the bootloader. Hold volume down and power.

I have tried this but although it comes up with the bootloader screen it flashes off gain as with the boot up screen. It does not give you time to do anything in the bootloader.

Are you sure the battery isnt completely dead? Did you drop the phone or do anything that may have caused this, or did it just suddenly occur?

No i have charged and recharged it until the green light comes on. The chap at the shop tried another battery also and this had no effect on it.
I dont recall dropping it. It is in a substantial wallet holder so i would think that would take the brunt of the blow even if i had. But it worked fine all night until it powered down then it just started to play up.
Right while messing a bit further it seems to me that the on off button is constantly activating. If i just hold the return button it comes up with the reboot screen and allows me to choose the various options. If i hold the volume button the fastboot screen appears but disappears just as quickly. All of this happens with out me touching the on off button so it looks like it is constantly trying to start up. The button does not have any visible signs of damage. Is this a normal failure point for these phones?
If it charges completely while it's off, then the board should be fine. You can check the percentage in your recovery mode if you can get there.
If the board is fine, it either means that the button is stuck or you have some gunk short circuit in the button.
If it's gunk, you might get away with some rubbing alcohol, If it's in a spray can, even better. If it stuck, it should be opened and see what's keeping it pressed.
I hope this helps.

My galaxy will not turn on it just vibrates! Bricked?

Two weeks ago my galaxy just stopped working. it was at a decent battery; just stopped. I tried charging it but the phone would vibrate. phone would come on, then shut off. I tried it multiple times and same result; a few times the phone would make it to the samsung startup animation, sometimes it would just flash the samsung logo, once it compleley got to my screen start before shutting off.
I brought my phone to get fixed. It took a whole week and the guy said my phone was just not fixable. It would work for a few hours then shut off again, according to him. I suspect he didnt work much on it though as hed rather fix phones with easy problems as mine was a tough one.
I've had to replace my phone with an iphone now, but right now, out of curiosity, I completely took my phone apart, and started using tweezers to play the power on button. The camera part just broke off (not the actual camera) but now my phone is actually charging! The red light is on, and click the main button, it shows the battery being charged. This has not happened ever since the phone broke.
Am I bricked? Is there hope for this phone??? Please tell me there is lol.
EDIT: My phone seems to have restarted! Turned it on and it's asking for my simcard what is GOING ON LOL

It just randomly shut off. It was if someone would constantly be turning the phone off as soon as I turned it on. But then I couldn't even charge the phone. No red light, no screen, nothing, just vibration. I would try to turn it on sometimes it would get to the boot up, sometimes not, sometimes nothing, just a vibrate.
I literally took tweezers and lifted the green board out from around the power on button (it's an actual tiny white button on the inside). and then it randomly started working again

Could be a power button failure. Happens somewhat often.
Could be battery related too, a cheap replacement battery could strike that off.

agree with what he said, it could be a problem with the power button or battery is not working
off topic did you really get 176Mb/s download or is it fake
if its real then was it WIFI or DATA , i have never topped 50Mb/s both wifi and data) but DATA seems to be 10x faster than my wifi

HELP! Tab S 10.5 is either frozen or won't turn on

So I've been using my Tab S for a minimum of 3-4 hours a day since I got it in Feb.
It is the Tab S 10.5 32GB version from Best Buy SM-T800
I've never dropped it, scratched it, etc. I've been VERY careful with it.
I installed Iron Rom on it in March (before Lollipop came out), and besides one freeze per month, have had no issue with it (I've also never updated Iron Rom as it never had an issue).
This morning I used the tablet for an hour while it was plugged in (and at 100%). I then unplugged it and put it on a table. An hour later, I went to use it, and the screen stayed black when I pushed any buttons!!
So I tried holding down the power button for 30 seconds. Nothing. I tried plugging it in. Nothing. I tried holding down volume down and power button for 30 seconds. Nothing. I tried holding down all the buttons for 30 seconds. Nothing.. I tried holding volume up, down, and power. Nothing. I tried holding volume down, menu, and power. Nothing. I tried holding volume up, menu, and power. Nothing. Then I repeated the above over and over. NOTHING!
I even waived magnets over it.. (I read it on the internet).. Nothing
This tablet is my daily driver. It won't turn on, it won't show me a charging screen. I'm freaking out! There is no physical damage to the tablet, no one else has touched it.. I'm freaking out man!!
Any suggestions before I jump out the window?

Hi, I think someone had this problem a while back. No matter what he did, it didnt seem to turn on at all. It turns out, it was some sort of hardware problem and even though knox was tripped, it was repaired free of charge. The only thing I can think of is sending it to samsung or something and say something like you were trying to update through kies and this happened ao you can get it repaired since its not your fault. I am leaning towards that this has to be an hardware problem since someone (XDA user FormeriPhoney) had the same issue with his. Hopefully it goes well with your Tab S!

Argh.. I talked to Samsung.. They said I would need to send the tablet to them and I would get it fixed/replaced but it would take 2-3 weeks. They have no advanced warranty to send a replacement out first.
The other (and more scummy) option is to go to Best Buy, buy a replacement, and then return this one as a DOA. It would save me 3 weeks of being without a tablet..
This sucks
Try POWER + VOL DOWN.
Hold for at least 30 secs.
If not you may find after a day or so the battery will fully deplete and then start charging.
Do you get any response on the pc when you plug it in?

Didn't work
It's unplugged now and on a table.

Oh.. And no response on a PC.
Yeah. This sucks. The only good news is that I actually backed up a lot to the external memory card last week as I was planning to go lollipop soon. The bad news is that all my customizations and other stuff is not saved (book marks in books I'm reading, etc). My titanium backup is from the first week I got my tablet.
But this is exactly why I won't get a phone without an external memory card. I would have lost everything.

IT"S ALIVE!!!!!!!!!!!!!!!!!!!
I woke up this morning,, resigned to no tablet.. still debating on going to Best Buy and getting a new one.. But I have 12 models coming in today for auditions.. So really don't have time.. But I NEED a tablet for notes with these auditions.
I walk over to the tablet laying dead on the cable.. and try plugging it in... and suddenly.. 0% comes on the screen.. it's sooo beautiful.. I want to make out with the tablet.. My heart leaps with happiness..
I turn on the tablet.. and it boots!!!!! It gets into Android.. and Nova Prime pops on the screen! But.. just as I couldnt get any happier.. it shuts down... It doesnt like booting at 0%.. So I wait another 3 min, half breathless... 1%!!! And I boot again. This time it sticks and I'm able to boot successfully into Android.
So here is my question. WTF happened? How do I avoid this?? Not being able to do a hard reset is some really mess up [email protected]#$%, If I was on a plane or other kind of trip, I would have been pissed... Let alone the wasting of literally 2-3 hours last night trying every single button combination for 2-3min at a time.
I'm surprised hard reset didn't work. I'd try it now it's working just so you know what to expect when you need it.
It may just be a one off. My tablet went into sd card mode once for no reason and that scared the heck out of me. I couldn't do anything. Left it overnight and after the battery ran down it started charging and then booted.
Never done it since.

Yup. Holding down the vol - and power after 20 seconds rebooted the tablet.
I would kill for a hard reset pinhole in the tablet.. Or a faster way to quick drain the battery.
Does the microusb port supply power when the tablets is turned off, if it does connect an usb device that will drain the power faster, like an portable hdd.

I've never known the hard reset not to work, no matter what state the tablet has been in and I've bricked mine God knows how many times.
Only when it dropped into sd card mode did it not work.
