Restarts automatically on start-up

After install Custom ROM on my A5 2017, it restarts when galaxy a5 2017 and android are displayed. I can't acces to recovery mode, only download mode work correctly. Can you help me, please ? Thanks.

I suggest re-flash the stock rom then restart other modifications
