I just want to be clear before flashing... this can be applied to an existing US998 -> VS996 phone, correct? I see "H930" in the first post, so I was concerned about that.
Also, the issue mentioned in the last few posts - I'm planning to dirty-flash from VS996 20d to this... that won't experience any issue, correct?
Will I need TWRP 3.2.3-6a or will my existing 3.2.3-5 work fine?
I prefer to be over prepared, instead of running into problems!
If for some reason the dirty flash gives problems, then clean flash.
