Samsung Galaxy S3 won't turn on after so many ways (Literally dead)

Okay so I have my Samsung Galaxy S3 for about 2 years now and it's having a lot of problems for the past few months. At first it had the sudden death syndrome (when it suddenly shuts down and having that boot cycle on the Samsung logo) and now it's fine. But 4 days ago I was sleeping and forgot to charge my phone. When I woke up and plugged in the charger it was charging just fine. When the battery indicator shows 100% I tried to turn it on and nothing happen. Just nothing. I plugged in the charger back and still nothing. The screen was completely black. No vibrations. I tried to go into the recovery mode and I can't. I've googled some ways including taking the battery out, pressing the power button for a minute and put the battery back in. Still nothing. I've tried like ALL WAYS to turn it back on. I took my battery and put it in my sister's phone and it worked just fine. So I know it's the hardware problem and I know it's not the power button too because I tried to turn it on by using the USB cable (plug in the charger and pressing the volume down and home button) and still nothing. I don't know what to do because I have so many things in my phone and I don't want to do any factory reset (if possible) by sending it for repair. But if I still have some options please tell me otherwise I have to get a new phone although I really need my old phone back. Thanks.

I assume, the NAND-memory is broken.
1. Save all your data, stored on external sdcard, on PC.
2. Try to get access by JIG (cheep) and ADB.

Can you explain a little bit further? I googled what you've told me to do and I have no idea. I'm sorry and thank you.

I think this may happen because your phone is 2 years old. Take your phone to the nearest service center. You need to save all of your data.

Yeah I am now planning to take it to the service center but I haven't backed up my phone yet and I don't know how since my pc can't detect my phone too.

The JIG may give you access to your phone, if you can't go into downloadmode. Imho it's the last option before throwing away. JIG costs 4€, so if it doesn't work too, it's a micro-desaster only. If it works, you can via PC and ADB access your data on the phone and copy them to PC f.e. You need to google again, but there are enough tutorials.

I'm not an expert in this, but boomboomer in xda-forum is. If you ask him, you get better advice.

My PC can't detect my phone too so I'm really worried on how am I going to back up my phone. I've asked the same question at xda-forum and boomboomer did reply to my post and it's just the same answer with you. Using USB Jig. Anyway, I think I am going to take it to the service center though. Thanks for your help!

I have a 2yr old S3 and its nearing retirement. Have you backed it up? (Google account/contacts etc, Samsung account/contacts bookmarks etc/ SD card/cloud backup)

If not you will have to track down someone who knows all the technical stuff given in prev replies.

Good luck!

Yeah I guess it's because my phone is too old and I am planning to send it to service center but I havent found a way to back up my phone yet. Thanks

It's need to back up before damage.

I did back up my phone using Samsung Kies before the damage but it was like a month before the damage so I do need all my data.

May your post have any use?
If yes, tell us about a way to get back the data, which isn't mentioned above yet.

I've send my phone to the service center and I've told them if it is possible to back up my data. I'll post here to let you know how they back up it if they can.

Ok to me it's firmware problem. Just need an update I did have a SDS before then I update it from 4.3 to 4.4.4. So it fix and rest it for a while to work sometimes

My S3 is on 4.3 and can't be updated to 4.4.4. Surprisingly, this problem occurred few days after I updated it to 4.3.

Hello Tom,

I've sent my phone to the service center and they did say it's an issue with the chip. They said that if I wanted to repair it I have to buy a new chip and of course I won't be able to retrieve all my data back. The thing is the chip costs half of the current S3 price (at least in where I live) so I thought I might better buy a new phone instead.

A month later, I bought an iPhone 6 and I am happy I'm not using an Android phone anymore (it is my first time using and iOS based phone). I know it has limitations in terms of customization, unlike the Android phones, but if it lasts longer than the Android then why not. Up to this current moment I have no problem in using the iPhone. I've lost all my data but I guess I've forgot all about it so I don't really bother about it anymore.

I am sorry if I can't help you but this is what happened to me.

Good luck in retrieving your data and I hope you'll find a solution.

Regards, Sara

I did and they said if I wanted to get it fix it would cost me half of the current S3 price so I just bought a new phone instead.

You need to take it to your nearest service center

Yeah I did and they said if i wanted to get if fix it would cost me about half of the current S3 price so I just bought a new phone instead.
