My Samsung Galaxy S3 won't turn on

[GSDer]

Welcome to the forums!

is this a potential loose connection of the screen? Need to wipe the phone?

You really haven't given us much to go on:
- model number/carrier/firmware
- when did the problem start?
- can you boot into Recovery mode or Download mode (and does the screen stay on the whole time)?
- if the phone is completely off and you connect a charger, do you see a battery graphic showing the current battery level and charging activity?
- does the screen show the normal boot up screens (usually 3 different screens) along with the usual audio tones?

Perhaps you should look at the post immediately above yours and try to provide the same information that was requested.

In addition, have you tried a different battery?
How old is the phone, and are you still using the original battery?

2 months back my s3 suddenly shut down
I took it o a place in wood green that could hopefully fix it but they said it was DEAD


But I don't believe that because every thing was limited on it

I'm not sure what this is supposed to mean. Can you tell us what the current status is?
- what model/carrier
- does it power on at all (any blinking lights; any vibration; any screen activity)?
- if you connect a charger do you see anything on the screen?

My phone is having a similar problem. Phone shows samsung logo for 2 seconds and shut off. Tried taking battery out process. Wont boot into recovery, but it does let me boot into odin or download mode.

It'll boot into Download mode and stay there?

If you remove the battery and reinsert it, does the phone turn itself on (without you pressing the Power button)?

What model/carrier/firmware?

Re: My Samsung galaxy S3 won't turn on

Ok I am New here so not sure if this the right way to post this... I have a Samsung Galaxy S3 with Sprint that won't turn on all the way.. When i try to turn it on I get the Samsung screen then it goes Black.. Tried to get into recovery mode but again I get the Samsung screen with the blue recovery writing in the right hand top corner and again the screen goes Black. Tried the Download route again I get the screen hit continue or just about to hit continue and it goes black. Any suggestions.

Welcome to the forums!

Tried the Download route again I get the screen hit continue or just about to hit continue and it goes black.

It goes black as in the phone shuts off? Or it goes black as in the phone is still on but the screen turned off? (You can tell by connecting it to a computer and running Odin - if Odin shows a connection then the screen is just shutting off.)

Have you tried a different battery?

If you take the battery out and reinsert it, does the phone turn itself on (without you pressing the Power button)?

With the phone completely off, if you connect the charger do you see the battery graphic showing the current battery level and charging activity?

What happened to start this whole mess?

Re: My Samsung galaxy S3 won't turn on

my wife upgraded phones so I was going to use her s3 since I cracked my screen on my nexus. Phone was fine up until the day she upgraded.. the phone lost charge and never re-charged... Had a friend charge the battery to 100% and check the battery in their phone worked fine. when you insert the battery the phone does show the Samsung splash screen with out the power button pushed.. phone does not show the battery graphic with charger connected...

This makes it sound like the problem is with a stuck Power button (or the actual Power switch on the mainboard).

You can try what's shown in this video http://youtu.be/KXSbBG4NV-w - if that doesn't help then smacking it firmly against the palm of your hand or a similar firm surface may do the trick.

At worst you may have to have the Power switch replaced.

Morining,
I have a problem with my samsung galaxy s3 too. yesterday i have finished a call and it went black. i have try to start it and i can see the logo of samsung and it goes off. it start at the same time and goes off and that process will continue on and on and on. please help. what can i do.

Re: My Samsung galaxy S3 won't turn on

Hello and welcome to the forums!

it start at the same time and goes off and that process will continue on and on and on.

This sounds like the "stuck Power button" problem. The first thing to do is to remove the battery and then reinsert it - if the phone turns itself on (without you pressing the Power button) then you'll have to investigate that issue.
It could be that the Power button (the little plastic piece that we press on) got jammed, or that the actual Power switch on the mainboard is malfunctioning.
For the former you can try http://youtu.be/KXSbBG4NV-w or you may have to open up the back and see if it's gunked up.
For the latter you may have to unscrew the chassis and clean the actual Power switch or replace it.

Re: My Samsung galaxy S3 won't turn on

Any ideas, I recently upgraded phones and I'm looking to sell my old gs3. But I had put a costom Rom on it awhile back but during the process at one point I ran into the same problem with the logo screen but I fixed it (I completely forget how) and that was that untill recently when I attempted to return the phone to stock by updating it to 4.3 with kies and that was fine it wasn't until I ran a master reboot that the logo problem resurfaced at that point I tryed to use Odin to flash stock firmware which after doing further research was a terrible idea to do with 4.3 but that's where I'm at my phone does not boot up past the Samsung logo luckily I can still access the dowload mode. Any help would be much appreciated, thank you

Re: My Samsung galaxy S3 won't turn on

UPDATE:I tryed flashing the root 66. I did the newest 4.3 tmobile download i could find which is what fixed it when this happened about a year ago but this time it did nothing. Also when i boot into recovery mode at the bottom under where it says Seccessfully applied multi-CSC it says in red lettering

E;failed to mount /data (Invalid argumen
t)
can't mount '/data'(invalid argument)
E;failed to mount /data (Invalid argumen
t)
E;Can't mount /data/log/recovery_log.txt

Welcome to the forums!

It's a good sign that it still boots into Recovery mode. Have you tried clearing the system cache and performing a Factory Reset?

Hopefully the firmware that you're using is this one.

When Odin completed were there any errors in the log?
