So I Reflash to original NAND with dash 13604 , update to new dash 14699 , completely forgot to Dump my new nand so try to do the glitch with my "old" NAND with old Dash. Doesn't work so I reflashed my original nand... but REd Light... probably incompatible with new dash. I'm noob totally lol but can I restore that?
Here's what I think
1. On your original 13604 dash you have a LDV value (numbers of fff's on fuseset), as you updated to 14699 your LDV had changed.
2. As you don't get new original dump after 14699 update, your last dumped nand wouldn't work probably because the LDv of that dump doesn't match with current one.
3. Similarly, if you flash with original 13604 nand now, it wouldn't also work, (LDV changed).
*** so far my suggestion goes, try booting Xell and get your LDV value, match it in 360 dump tool, if all ok get a donor nand ( since you don't have 14699 on your nand, so you can't dump that) and build your image.
This comes totally from my sense, I never faced this kind of problems, so if wrong, don't take seriously.
