My FE is rebooting repeatedly after upated 8.0

Hello, everyone!
I just received my FE today and updated it to Oreo immediately, and I'm facing rebooting problem right now. It rebooted for a short time of freezing for no reason. I'm stock rom now, and I did factory reset and wipes in recovery mode. It helped nothing but rebooting. I tried to flash the stock rom again with Odin 3.12, but it rebooted immediately. I checked the FRP Lock and OEM Lock. Both of them are off. I'm really confusing right now. By the way, the model is N935L. Can you help me? Appreciated.

You need to use odin 3.13 for oreo builds. Try that.

Thx. I did that. But it seems that flash the stock rom didn't help the freezing and randomly rebooting. At least I flash the stock rom for 3 times. What may cause the randomly rebooting? Appreciate.
