Official 8.1 Update. Boot loop! topic

Today, I've got official update to 8.1. Firstly, it udpated upto xxx.166 veresion. On the next step, it updated to 8.1. I've been seen geers for few minutes, then it booted and started boot loop!

p.s. The same issue I've got when tried to install Developer Preview (phone was fixed by garantee).
