Default Flashing, cannot attach mtd.

Good day maam and sir, I've got a problem with my device.

My device is an mtd device, and I made a stock rom of my device.

And recently I encountered a status 0 error, I then change the update binary.
I was able to successfully flashed my rom, but after, I am stuck at bootlogo, frozen.

Then when I go back to recovery, I see "cannot attach mtd 16" error. Sometimes, "Cannot attach mtd 14" error.
What is the problem?
