Important things to know

You have to be aware of that all EMUI versions are pretty different in almost all things (kernel, blobs, partition table, dtbs, etc.). Huawei OTAs are also resizing the ptable, so because of that, for example, all EMUI 8 devices (launched or upgraded) got Treble support (In fact EMUI 5 had a vendor partition already but that was smaller than on EMUI 8).
