I think is because when you install this official "3.55 dex downgrader"... the hases stored in syscon (updated in this installation) are the same than in a 3.55cex
This is a coincidence btw...
Also, when you are in "factory/service mode" this checks are disabled (so when you install a firmware from factory/service mode, this installation updates the syscon hashes correctly, and the check returns a "match" and all works fine)

But dont take my words as an expert, im just talking about things that are involved in the process, but i have not much idea about them
