First thing You have to understand about QC based S4 Samsung - downgrade is not possible, even if You replace eMMC.
Further, if phone was flashed to 4.4.2 version, You have to use exactly same or greater version of firmware to repair it.
128mb dump to ROM1 from required version will power phone on. Of course, in case You have compatible eMMC with correct EXT_CSD flag.

is there the imei and SN in the 128mb dump file? and reading with jtag?

there is efs partition in dump but after full flash with 4 part firmware your imei will be 049..... then you can write imei with other tools
