I was discussing with a friend (@mrissaoussama) about how people could extract a bricked NAND from a Wii using bootmii and change files, to fix the NAND. It isn't so simple to add random files to a 3DS NAND, but.. Say you have a bricked NAND on a9lh with no NAND backups. You also have another hacked 3DS using updated sysNAND a9lh. Can't you make a CTRtransfer out of the brick, transfer it to an emuNAND of the target system, fix the files using sysNAND's files, then CTRTransfer the working emuNAND back to the bricked system? Or are we missing something? The steps would be the following. 1. Open Decrypt9 on the bricked system, and create a CTRtransfer file using the bricked nand. 2. Transfer this bricked CTRnand to an emuNAND of another 3DS. 3. Using GodMode9 and sysNAND, copy the files that caused the brick (for example, a bricked HOME Menu on a American 3DS) a content folder named 0008f02 from sysNAND. 4. Copy the file/folders from sysNAND and paste it into the bricked emuNAND. The emuNAND would now work. 5. Finally, create a CTRTransfer file from the emuNAND. 6. Open Decrypt9 on the bricked 3DS, then install the working CTRtransfer file. The system should now be reverted to its state before the brick.
