Why is my infinix zero 3 not rebooting?

My phone had been working all fine till a few hours ago. I put it on charging and took it off the charging when it had charged around 50% but when i switched it on, it didn't work. Instead, the infinix logo shows up and then fades repeatedly. Tried the normal/fast/recovery reboot but all of them ended up with same infinix logo showing up repeatedly.

Can anyone please guide? I'd be grateful.
