I have a ASRock J3455-ITX Board with integrated Intel® Celeron® Prozessor J3455. I'm currently trying to update from my current version (DSM 6.0.2-8451 Update 9 with Jun's Loader V1.01, machine type DS3615xs) to the newest possible version. I can see from your matrix that I need a "Haswell or later" CPU for the recommended combination 1.04b loader and DSM 6.2.1 (not 6.2.2 because you mention that this DSM version fails on AsRock JXXXX). The CPU of my board (Apollo Lake / Goldmont generation) is a 14nm architecture and it was released in 2016 that makes me think that it is indeed "Haswell or later", but I'm not 100% sure, because the atom line is a parallel product line (Haswell is not part of this line). Is this the way to go for me? Flash my USB to Jun 1.04b and then on the DSM interface do a direct manual update to 6.2.1?
