Why my phone boot to download mode

[AC Question]

I have tried all the possible protocols stated on this forum and it still not working with my phone.. Instead of my phone booting into download mode it will boot phone normal showing MEDIATEK, and when I try again it will boot phone normally with the samsung boot screen.. Please I need to fix my phone it is a samsung s4mini 19190 . Thanks

Does it fully boot? What fw is it running and what is csc code? Seeing "Mediatek" suggests you may have a fake. The s4 mini has a Qualcomm processor
