If it has PCB P/N of 105-01738-00 then flashing US/EU fw to it should be possible.
EDIT: Confirmed. 105-01738 found in CHN V2.30 firmware so physical hardware is identical. HWIDs do differ, US/EU is 1567 and CHN is 1822. However, either complete cross-flash with HWID change to US/EU or for safety hybrid fw flash maintaining CHN HWID using original boot.bin combined with US fw_all.bin should succeed. All forced/cross flash procedures carry some element of risk though.
