Google this tool "std unpack" open to first link and download that tool.
Drag your recovery.img to STD unpack and you'll get your files.
Alternatively you can also use kitchen to unpack the recovery.img
Just go to advanced options then go to boot unpacking tools and follow steps as suggested

EDIT: nevermind i did it with kitchen like you said in advanced options, this is what I have in recovery.fstab
# mount point fstype device [device2]
/misc emmc /dev/misc
/data ext4 /dev/block/mmcblk0p7
/system ext4 /dev/block/mmcblk0p5
/cache ext4 /dev/block/mmcblk0p6
/boot emmc /dev/bootimg
/recovery emmc /dev/recovery
/emmc vfat /dev/block/mmcblk0p8
/sdcard vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1
/sd-ext auto /dev/block/mmcblk1p2
How should i change the lines: format("MTD", "system"); and mount("MTD", "system", "/system"); according to that?
Again, thanks for the extensive help
