[Q] Samsung Galaxy S3 wont turn on! GT-i9300. Pleaase Help - Galaxy S III Q&A, Help & Troubleshooting

Dear Developers..
my phone is unrooted, running on the official built in ROM and has never been experimented with.
Last night the phone was on low battery and went off. Today morning i plugged it in to charge and the charging never happened nor is the phone coming on. I tried charging the battery on an external portable charger for an hour and tried again but still no use.
The phone seems dead. Tried all ways to make it start, removing the battery and pressing the power button in case any stored power (like in laptops), tried power, home and volume up/down button, kept the battery out for over 2 hours and tried again, yet nothing.
Please advise how to go ahead. The phone already has a problem of running on Factory mode since the last two weeks, a screen pops up and remains on the desktop with all technical details of the phone and the lock features dont work ever since. data, wifi and other apps on the fone work properly. Tried to find a way to fix that but found posts requesting to root the fone to get this fixed. so havent fixed that yet.
Please help!
p.s. im not an engineer so please try to explain in simple english, however am able to work around to fix this on my own.. a little technically sound.

Good luck!

You have a hard brick, either usb jig or repair centre.

Please note this phone has never been rooted. So im not sure if USB jig will help. moreover for USB jig i though the fone should be able to switch on at least. but here the fone just wont come on, nothing comes on.

You don't understand what a usb jig is or does.

How about THIS ?

Samsung Galaxy S2 won't boot to main menu, and has seizures.

I'm having a huge problem with my T-Mobile Galaxy S2, and not it won't even completely boot up. The issue had already been around, but never this bad. Usually, when I would use my phone, it would just randomly reboot on it's own. Now, I can't even get to the main home screen or menu. When the battery is inserted, the phone will automatically try to turn on. I'll get the Samsung screen, then the "Samsung Galaxy SII Android 4G T-Mobile screen", then the phone will glitch for a second, black screen, and it'll almost have a seizure from then on. When I say that, pretty much what happens is that the screen will go black, and it'll pulse with vibrations. It'll vibrate, stop for two seconds, vibrate some more, etc. That's all it'll do from there on. It won't try to turn on when I hold the power button, and the vibrations won't stop until I take the battery out. There is no water damage, and there's just normal wear on the phone. I've had the phone since the drop, and for the most part, it's been great until now.
The phone is not rooted, and I have not installed anything crazy. Come to think about it, I didn't really even have too many apps installed on it to begin with. The phone is under warranty, so I had T-Mobile send me a replacement. My main issue now is that I have content on there that wasn't on my SD card, but on the internal hard drive that I find extremely important, and want to keep. When I connect the phone to my computer, nothing comes up because I didn't "connect" it to the computer as you normally would have to do from the phone, before the extra drives pop up on the computer. Without getting into the main menu and manually connecting the phone to the computer so that the drive will pop up, what can I do?
I've tried taking the battery, sim card and memory card out, letting it sit for a few hours, and plug it back in, but it does the same thing. The battery isn't bad, because it plugs into the replacement phone that was sent to me, and works just fine. I've also plugged into my additional batteries, and it does the same thing. I can't do the "hard reset" where you hold volume up & down, then the power button because what happens is the phone will restart itself before I can get to that point. I tried it when I was on the phone with T-Mobile, and the associate at one of the retail locations tried when I went to get a loaner. I've tried hooking up the phone to the Kies software, but it won't recognize the old phone. It will recognize the new one with no problems though.
I am in no way am I well versed with the process of flashing it or installing different things on the phone. I just used it casually for phone calls, texts, web, and an occasional game or app. I'm just stating this so that if there are any specific tips that anyone could recommend, please if possible, explain in a bit more depth, because after I posted my title, I found the related threads, and most of the steps that were recommended to others that had problems sound a bit foreign to me. I just really want to recover the photos and documents that I had on the phone before I send it back to T-Mobile.
These are the threads that I've somewhat referenced so far:

I can't seem to find anything with the same symptoms as my phone though. If anyone could let me know, that would be great. I just really want to get the content off my old phone, it's just extremely important to me. I'll be waiting on any replies. If you need and more information about what the phone is doing, or what I should try, please mention it. I will try to update this as I get replies, since I am supposed to send the phone back pretty soon. Thank you in advance.
a usb jig to get see if you can get to download mode would be a start.

You described my phone EXACTLY. I have tried everything you have, as well. I've read for hours on the internet trying to find a way to retrieve my pictures, etc. I have a replacement as well, but I haven't sent the old one back yet. I should have done so already, but I desperately need my stuff out of this phone. I'm going to be charged soon for the new one, and was trying once more before I sent it to the company. Exhausting all the info and tricks I've learned from the web, I ran across your post. Can you PLEASE tell me if you had any luck at all? Thank you....

That's nice, but this is still in the wrong forum. The people who could benefit from it won't see your 'help'.

Putting generic/non-descriptive titles, especially silly ones like "Urgent help" do not make people help any more quickly and in fact will slow down help because many people simply ignore topics that are not titled correctly.
Also, This topic has been discussed MANY, MANY, MANY times over so you have no need to create a duplicate topic and then sit there and wait for answers when you can help yourself by looking and reading.
If your phone has simply died and wont turn on then its dead and you will need to replace/repair hardware. In the very least try a new battery.
Have you tried download or recovery mode or a USB jig??
Also it would help if you were honest because diagnosis/fix may be more relevant, have you tried flashing something to your device?
And everyone here should stop whatever else they're doing to 'urgently help' you why exactly ?
I don't see why this is urgent at all.

[Q] Samsung galaxy s3 GT-i9300 reboot on start screen

Hi. My name is Erwin. This is my first post in this forum and I'm rookie in this kind of themes. It Turns out that I bought a S3 shabby. it cost me 50 buck.Y thought that I could fix it but I could'nt The problem with the phone is as follows. When I put the battery in it powers on almost immediately without pressing the power button, It shows the samsung galaxy s3 i9300 logo and restarts again and again without going out of this state. It doesn't allow to charge the battery. I have tried to get into recovery mode to do a wipe but it's impossible as it restarts and will not let me do anything. The computer does not recognize it or kies or odin. If anyone can help, I would appreciate. I will provide a you tube video link to watch the exact issue. youtube.com/watch?v=B_5_AzChlJQ&feature=youtu.be

Can you make it go in download mode?
Nothing. I invite you to watch the video and tell me your conclusions or some kind of help.

[Q] firmware issues

I have the international GT-19300 s3 and a few days ago. I installed the latest firmare update. I was on Wifi at work and when the download was
complete. It gave me nothing but a black screen. I think when the download was complete I left the area where the wifi connection was and it
messed up my phone. I tried holding down the home, power and volume button up and it will show 27 percent and then the little android dies and
my phone shuts off. When I push the power button. I only get the s3 galaxy logo and then it immidetaly cuts off. I took it to the shop today and he
said it might be a boot issue so he gave me a link for bootloader, but I do not understand it.
does anyone have a link where i can plug my phone to usb to computer and reboot my phone...
I had my phone 2 years, but I'm not savy with these phone softwares.
thanks
Read the guide in stickythread on how to flash back to stock, then factory reset.

Hard bricked Alcatel star

Hi, first sorry for my bad english. As you can read from the title my Alcatel One Touch Star is hard bricked.That happened when i was uploading mp3s from the PC to the phone and I just took the usb out from the pc.Then the phone started reacts very strange so i decided to restart it but it turned off by different way and didn't turn on again. I'm not coming straight up there. I have tried many things from the google and other threads here but my phone don't show any sign of life. I tried all methods of clicking buttons for going into recovery/download mode( i don't know how it is called exactly ) but nothing works. I tried pluging it into PC but it doesn't show up. That is why i think is hard bricked. I have given the phone to a man who fix phones and he told me that the phone is dead .I have heard that this is the best android forum so that is why i'm looking for help here. Sorry if the thread is in the wrong section.
