There are companies as Oneplus that post their OTA updates on their webpage in order to let users download them if they want to flash the update instead of waiting for the OTA. By doing that, you just can download the file and flash the update from recovery mode.
Everything is at their own risk obviously. This will solve most of the problems that I have seen with the Oreo update(User of beta with no update yet).
I believe we should support this post to HMD listens to this!
Thank you very much.

People always say that, but then, when things go wrong, they always complain about the brand.
