The local asian JCV files are encrypted and cannot be used by US/EU fw devices, or even other Asian fw devices. eg, TH fw cannot see PH jcv and vice versa etc., because there is different encryption on each. Asian units which have identical hw, i.e. same HWID, can generally be cross-flashed to another asian fw np. For a US/EU device my advice is don't bother.
