JTAG Restoring original nand with bad blocks

[Miggidy]

Hi guys,

I have a question, I'm looking to restore my original nand dump. It has bad blocks, so do I reflash as is, or should I fix the bad blocks first?

Sorry if this comes off a bit noobish.
I ran my original nanddump through Nand Healer back when I did my RGH. But I have both original nands, the one with bad blocks, and the one that I repaired with Nand Healer. Just wondering which one to go with....

Thanks in advance!
