Hacking Nand backup info.

Iv got my nand backed up when i was on 5.02 just asking do i need to keep backing up my nand for every fw update that comes out? or will the one be fine from then on?

You need to keep a backup for each pretty much, as soon as you upgrade, you can remove your old one. Especially if it blows efuses. Then you need to have something to patch your fw each time you boot.

Why would i Need to patch my fw each time? Was thinking the Switch sx pro would take take of the rest for me.

Because efuses and problems whit downgrading, you need not update and have 1 backup or to update and backup every update.
SX PRO has this problem, atmosphere would not, sience it uses emunand, your sysnand would remain the same version and the same backup should work

You could always store the original dump and then for any new dump create a binary diff which you can apply to make the "new" FW with a copy of the old file

Always backup the nand always make a couple copies of each nand save the old ones to because those fuses will get bypassed eventually.
