I compared them and it seems the gmapprom.img is the same, same size,header date and version.
May be something new in additions files ? If yes which type contains them ?
thanks

The gmapprom.img in type1 to type4 is the same map as the one leaked in March. The gmapprom.img in type5 and type6 is the same map but its CRC32 checksum is different from the map in type1 to type4 although all have the same size.

Several kinds of JCV files with different resolutions are used in the installers. JCV files with the same size have the same content.

Type 5 and type6 are almost the same except type 5 has additional ASR files, apparently for 3790T.
