This is for all those who have soft bricked their phone, if you are experiencing a bootloop or some other problem here is a detailed guide how to get your phone back to working condition. If your phone is not entering download mode or recovery mode and even if a USB jig is not possible or not working. This is the guide for you-I do not know whether this will work in all situations but you could still try it if you have no other alternative. The Galaxy SL has a hard reset button between the camera lens and the speaker...
DO AT YOUR OWN RISK!
1)Open the back over
2)Check between the Camera Lens and the speaker
3) There is a hard reset button which is a small cavity
4) You will need two people for this.. Keep that cavity pressed with a pin
5) Keeping it pressed use the download mode combo- Volume down + Home + Power pressed.
6)Wait and try it a couple of times and your phone will enter download mode
7)Flash to a stock firmware
