I - Problem description
I have been experiencing a problem with my Samsung Galaxy S4 (GT-I9515). The latter turned off and didn't want to start up again.
Two days ago, as I was using my phone, it went off. When I tried to start it again, by pressing the power on button, it just showed the Samsung Logo and then went off again. I have tried several times switching it on, but in vain, it just shows the logo and goes off, yet sometimes it goes with the start up a little bit further by giving the start up sound and the next logo, but then it just goes off again.
II - Solutions tried
1- I have tried a few options I found on the internet, such as formatting the device by means of a pressing the Home key, the Volume up and power on button. However, the problem seems to persist.
2- I have lately tried to flash the device by Odin3, but even the flash did not solve the problem.
After having downloaded a number of firmwares and trying them on the phone, it still didn't work.
At first, I used to download, by mistake firmwares concerned with the GT-I9505 version, and the flash did not pass; however, later I knew that I had to use GT-I9515 firmwares as they are the ones that match with the device, so the flash would pass, but still the phone would not work.
Actually, firmwares I find on the internet seem to be always accompanied with regions/countries, hence one should know the region/ country of his phone to download a specific firmware that would work on the phone, nonetheless, I could never know to what region/country I should download the firmware, as my phone certainly does not belong to the country where I live, as it is imported from abroad.
Unfortunately, even the white sticker under the battery on the phone, does not seem to belong to it, rather it has obviously been changed by another one. So, I can never know the exact data of my phone so I would download the right firmware.
1- Do you think that flashing the device with the right firmware would solve the problem?
2- Is there any possibility that I can know information about my device, knowing that it does not turn on, and the sticker under the battery has been replaced with another one that does not belong to the phone?.
3- What other solutions can I try to fix the issue?
Thank you for you time, help and coordination.
