SCCM: In-console Update stuck in “Checking prerequisites”

I am installing quite a lot of SCCM environments these days and several times bumped into an issue when in-console update from one version of SCCM to the next one stuck on some step.
For “Downloading” Microsoft recommends to restart SMS_Executive, but for “Checkin Prerequisites” it was more difficult – Community recommended to play with SQL databases or start update from cd.latest.
None of those methods is supported by Microsoft though. (Se more here: http://gerryhampsoncm.blogspot.ca/2016/04/configuration-manager-cb-upgrades-what.html)
With version SCCM build 1706 Microsoft finally introduced a CMUpdateReset tool allowing to rectify a failed state for in-console upgrade by deleting a failing package. Here is a link to KB describing the process: https://docs.microsoft.com/en-us/sccm/core/servers/manage/update-reset-tool
