So far we have reported successes with the PW2, PW3, KT2, and KV.
(Most were using the English interface, but there was also a... PW3 I think... using Chinese.)
So if specific batches within a device generation (e.g. broken down by whatever requires an individual update package) do NOT matter, then it should work universally.
If devices broken down by serial number DO matter, then we still need those serial numbers reported, so, just in case....
