What should i do?

[Jerry 77827]

I Have a Huawei mate 8 NXT-L29C185B190. Couple of months ago I rooted my android. With TWRP and unlocked bootloader. I by mistake formated my phone with TWRP and then all my data including the Huawei mate 8 themes and icons were gone. The icons were like the older versions of android(messed up). Just a minute ago I got an OTA update. So I removed my root by SuperSU and then tried to update it. But then it redirected me to TWRP. I didn't what to do so I rebooted the device. What should I do? (The update is not installed)
