Hacking GATEWAY 3DS EMUNAND PARTITION BACKUP HELP

[windydoom]

Hi,

Is there a way to backup your GW emunand firmware and restore it before updating. I have GW 7.0 firmware and and want to back it up so that if there is any issues with updating to 7.1 I can restore it.

If this is possible how would I back it up and how could I restore it???

Make an image of your SD card (the one in the 3ds, not the micro card in the gateway) with win32diskimager. If you need to, you restore it with the same program.

Note: This won't help you if you mess up and update your real nand, just the emunand, so be careful when you update.

theres an actual program that will extract JUST the nand partition(better than dumping the Whole SD for the sake of 1GB partiton...especially if you want to switch to a smaller/bigger SD card in future)

you can backup and restore emunand partitions with that
