Even if someone were to get a US version could you flash an international ROM through flashtool? I just flashed a UK ROM on my US-spec XZ to get the FP scanner working.
The US and international Xperia X differ only in minor firmware changes. Baseband (radio) is actually identical between the two. For some reason Sony will not run a fingerprint reader in the US. As near as I can tell, stripping out the fingerprint reader software is the only difference between the two variants of F5121. But for Sailfish X you must get an F5121 single SIM and not an F5122 dual SIM. That's the only proviso I've found.
