This reminds me to add checksums to my uploads!
I first decompressed with upx
upx -d nubia\ Z20-for\ Android\ P-TWRP-3.3.1.exe
Edit: I downloaded 1.03 and 2.03 and try to look for diff in some files with
vimdiff <(xxd "EUROPE-ASIA/file" ) <(xxd "US/file" )
and they are a little different I didn't try the android files (system,vendor,boot etc) because they are too big though
