I'd like to substitute the brand ROM on an huawei p10 with the official ROM one can find in the popular xda forum or alike.
I'm a bit paranoid in this regard so, in order to be reasonably sure no one tempered the "official" ROM, how can I verify it's actually the one that comes with unbranded Huawei phones since, as far as I know, Huawei doesn't provide the ROM itself nor the md5?
