How to make a backup from internal storage of my Galaxy S3 Neo while it stucks on Samsung logo screen? My Galaxy S3 Neo has stopped working without any clear reason! I woke up and looked at my phone screen. It was showing the logo of Samsung. Then I turned it off by removing the battery. Since then I have been trying to turn it on but again it stuck on the logo screen. I tried first, "wipe cache partition" from recovery menu (by pressing power bottom+home+volume up) but it did not work. Second, I tried using another battery and it shows that the battery works well. Third, I start using the safe mode but it could be loaded. There I have two questions:


I do not want to miss my personal information, photos, apps, etc. which are in my internal storage. This is very important for me. Please help me:(
What should I do with the problem?
If you have tried enough booting and it won't boot than all feasible option you have are


look if only flashing system partition is possible and if it doesnt remove your data 
or if it is possible to root without loss of data, if possible do so and install recovery and extract your data to PC and reflash the firmware
