Need help - S7 freezes all the time

My phone does not even reboot at all anymore, nor recovery mode, nor download mode, it seems bricked but thanks anyway everyone for your help, I tried, sometimes it fails

A Samsung device is quite UnBrickable !

for sure, the phone donā€™t charge when it is in download mode

it is charging in recovery mode if using TWRP, in case of recovery-e i donā€™t knowā€¦

try to let it charging for all night, then try to boot in download mode and flash itā€¦

Thanks, I tried, I still canā€™t reach the download mode anymoreā€¦

Do you mean that the phone did not boot or that you couldnā€™t reach download mode ?

The screen stays black, nothing happensā€¦

it donā€™t vibrate when pressing power ? or when you plug it ?

no, nothing happens, black screen, no vibration

It might be dumb to ask, but could the battery be faulty ? Also, did it stop booting after a certain action ?
