Phone will not boot past samsung logo. - T-Mobile, Samsung Galaxy SIII

Hi everyone,
As the title says, my phone simply will not boot past the samsung logo. I insert the battery, a few seconds later there is a vibration. Then the samsung logo appears, and it shuts down. It does not reboot itself; it just suddenly dies. After it the shutdown, all buttons are unresponsive; holding the power button will do nothing.
I have tried plugging in the charger both with and without the battery inside the phone. When I plug in the charger, the red LED that indicates that it is charging turns on. After a few seconds it vibrates, then almost immediately the red LED light flickers off, and everything is just as unresponsive as before. Leaving the charger inside will yield no results or change.
I have tried to turn my phone on with the battery and charger plug into the phone with a few variations. First, charger first, then battery. The battery is inserted within a second or two of plugging in the charger. The red LED light appears, then the light turns off right before the vibration. The screen shows the battery logo that indicates the phone is charging. This image appears for a few seconds, then it becomes unresponsive as before. Second, battery first, then charger. There are two more variations for this. One is battery, then plugging in the charger right after the battery is put in (before the vibration is felt). After the vibration, the battery logo appears for a few seconds before it shuts down and becomes unresponsive again. The second variation is: battery first, then vibration, then right after the charger. Same result as before.
I have also tried to remove both sim card and sd card. No avail.
I have tried to boot it into recovery mode, as well as download mode. Nevertheless, the phone will shut down before getting into any menus.
I have tried to tap the power button multiple times in case the power button and home button were stuck or jammed. However, I doubt this is the problem.
My computer will not recognize my phone, since I cannot boot it past the samsung logo.
I have tried using different batteries, same issue.
I am aware that a factory reset may be an option that I may have to take, but I have some important data on my phone that is not backed up, and I would very much prefer not to lose it all. I would appreciate any insight on how to fix my problem.
Thanks!

Mine was doing this for a bit until I realized my power button was stuck. The button seemed to press fine and all and looked fine physically, but the contact was somehow stuck. Take apart the phone, direct some compressed air into it using the little 'straw' for the nozzle to focus it... Also try pressing the button a bunch of times hard, etc. And see if that helps.

Fixed it! Opened it up, jiggled around with the power button stuff. I had no idea what I was doing. I blew, with my mouth, really hard on it. Now it works. laaaaaaaaaaaaaaaaaaaaawwwwwwwwwll
You helped! Thankyou

Now would be a good time to backup that important data. A lot of the time, that's is just a temporary fix and it may happen again.

[Q] T-Mobile G2 refused to charge, deleted all my widgets, and now won't boot.

I've been charging my phone all day but It's been refusing to accept a charge. I rebooted it, but the best it would do is charge, then tell me to connect the charger, then intermittently start charging again (even though it was plugged in the whole time). I tried different cables, AC adapters, my PC, with no difference in performance. After a reboot, I noticed it had decided to remove all my widgets, but not any shortcuts. I'm running CM7 Gingervillain. After puttering between 2 and 15% battery level for hours it then started refusing to boot, blinking an orange light at me, sometimes, and then the light would stop.
I took the battery, sim card, and SD card out, unplugged it, and started to vigorously "ninten-blow" all the contacts. Saw a stupid looking post on the web that said I should remove the battery and hold the power button down for a while and try again, so I did that too. It booted, magically, then told me to connect my charger, even though it was connected, and died for the last time.
Held down the power and volume down to get into hboot (I think?) and told it to reboot from there, it just turned off. Tried again and selected clockwork recovery, it worked! All right now I'm getting somewhere. I selected reboot now from the friendly black menu and was greeted by a black screen with a top hat wearing gear-and-arrows-amalgamation (the clockwork logo and no text). It stayed on this for about a minute and that was the last thing the display ever displayed.
Now I have a dark screen and the orange light will blink up at me inconstantly if I try to boot it by using the regular power button or power + volume down. That's when I decided it was time to register a new account here and make my own post instead of lurking.
Please help me.
EDIT: Sometimes the orange light will blink when I don't do anything. It is very inconsistent. Like it's trying to message me with morse code.
EDIT2: Got into hboot, clockwork recovery, selected "backup and restore" this time I am greeted by the clockwork recovery logo with no text again, it displayed this for twenty minutes and then died.
EDIT 3: Strangely, if I set the phone down, the orange light will not blink. It will blink without any particular interval if I pick it up, even if I'm not pushing any buttons or touching the screen. The blinking continues for a short period of time when I set it down, and then stops.
EDIT 4: I have arranged the phone and some furniture so that it is dangling by it's charging cable, which as caused the orange light to glow constantly. Perhaps I just have a bad micro-USB port.
EDIT 5: It booted up fine after charging while dangling. I have a bad Micro USB port, and am paranoid. I guess I will forever have to awkwardly charge it.
CRISIS AVERTED I AM DUMB
I recognize you've tracked your issue down... but as an aside, when you're trying to select an option in Recovery it sounds like you might be trying to use the Power button instead of the trackpad? I believe that's why you're seeing the Clockworkmod logo and no text when you "select" your option. I did this once too a long time ago and freaked myself out.

[Q] One X crashed when charging and won't boot past htc screen or power down.

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..

S 3 Start-Up Problem

Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.

[Q] HTC One X. Stuck in a restart loop

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:

My issue was water damage but would cover any damage to the power flex cable.

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.
