Good PM.
i have an MT6592M device with Android 5.1 kernel 3.10.72. im having problems making a full backup or dump of my rom. i have created readback from sp flash tools but its not creating preloader.bin. i makes the other necessary files when processed in mtkdroidtools > "to process the file ROM_ from spflashtool" option but there is no preloader.bin. the files seems to work fine since i tried it couple of times reflashing to my device. i tried to root my phone, checked that its been properly rooted, installed busybox and use mtkdroidtool's backup function and it fails at making preloader_and_dsp and wont backup the partitions aside from /system and /nvram, error msg says : "ERROR : Zero file, no space left on device!" and looking for answers there seems to be no method that worked in my case.
so i use readback to manually dump the preloader.bin address and using hex editor to view, it doesn't seem right since the header is wrong and its starting with EMMC_BOOT. i don't think i can reflash this preloader.bin file in case i will have issue with my device, right?
so, i need help if there are other ways to backup mediatek roms, or dump only the preloader.bin and make it flashable with spflashtools or anyone who can clean-up the dump i made and make it right for flashing back.
thanks.
here's the partition info as reported by mtkdroidtools and attached is scatterfile:
