Hacking mirror copy of CFW how?

[miamore]

is there a way I can create a mirror copy of my CFW.. I want to move my CFW to another memory card because my new card will have faster copying speed than the old one.. they have different size capacity

It works with the cfw too.

will this work with SD card with different size? my old SD is 32gb and the new destination is just 4gb..

never tried CFW, but if it's the same with GW, for SD card with smaller size personally I'd choose to use emuNAND tool

on the old SD card
1. create emuNAND.bin using emuNAND tool. keep it somewhere safe
2. backup all contents of your old SD card somewhere, simply using Windows Explorer or any file browser

on the new SD card
1. create emuNAND partition using 3DS (can also use GW create emunand feature)
2. inject NAND dump to new SD card using emuNAND tool
3. copy all backed up files to new SD card. if you are limited in space, you can choose not to copy unnecessary files (photos, etc)

Emunand Tool doesn't work with the cfw rednand, but he can use 3DS Dual EmuNAND Creator instead.

- To extract your cfw rednand, run 'Extract emuNAND 1.bat' as admin
- To inject it on your second sdcard (you must do a format emunand first) run 'Inject RedNAND 1.bat' as admin.
