Problem Continuous reboot Huawei Y6 2017


Good evening,
I have a Huawei Y6 2017, which has worked perfectly since I bought it until ... today. Its battery ran out, I put it on charge, but after I restarted it, after it was in the main screen for about 30 seconds, it restarted and has been doing so for several hours. Can you help me finish them off? Thanks.
