As I Know Router Don't Have EMMC Or EMCP Chip So It Won't Work With That Some Of Router Having JTAG Points But New Router Don't Have ...Mostly New Router Using SPI Connection Read Write...I AM Not Sure Medusa Pro Support SPI Connection Or Not..Better Post Motherboard Clear Image With All Chip ..So I Can Check

according to the datasheet if the chip is named : FMN4ET2TCK-25IG

FMN4ET2TCK-25IG is a 'NAND Flash Memory'
eMMC ISP Interface not for NAND Flash Memory,
Bcoz eMMC have different I/O & Nand Flash Memory have different I/O.
