old 3ds bricked unable to mount ctrnand or ctrnand firm please use a external one

1. When you boot the system holding Select, what happens?
2. Do you have the latest Luma3DS boot.firm on your SD card?
3. Have you tried performing a CTRTransfer?

 

Your Luma3DS is installed on the SD card, but you don't have a copy of it on the CTRNAND.

Failure to mount the CTRNAND error means it's a bricked firmware. Did you try region changing, downgrading, editing system titles like the HOME Menu, or were using EmuNAND by any chance?

 

Have you tried doing a CTRTransfer like I suggested?

 

Normally,a ctrtransfer to 11.5 fix this problem, I use the payload Decrypt9 to perform a ctrtransfer,but before u do that,try the ctrtransfer with godmode9

 

The ctrtransfer "format" the system,it doesn't wipe the data of the sd card,but kida "wipe" the data of the 3ds

 

If done properly, tickets and whatnot can be preserved during a CTRTransfer.

 

But if u are talking about that,maybe ur sd card corrupted

Yes,know that,the gm9 have a script to do that action,I was talking about just the ctrtransfer,like,only that,I forgot to tell this

 

@matthewsmith, before you use CTRTransfer,

1. copy everything off the card onto a computer
   
2. reformat it in FAT32 + 32 KB cluster size (Windows File Explorer -or- guiformat if bigger than 32 GB)
   
3. full Write + Verify the empty card with H2testw

Data disappearing out of the blue would mean dying or fake SD card.

CTRTransfer done with a bad card can lead to further bricking.

 

Whats your sd card brand?

 

Except for obvious looking fakes or counterfeits, judging the brand is not enough to go by these days.

For example, there are a lot of knockoff Sandisk and Samsung found on eBay that are very convincing when compared to the authentic versions.

Counterfeits are not limited to those two brands, but they're the most popular. Even popular online (ex, Amazon) and physical stores can be spiked with fake goods mixed in with the real stuff.

 

It doesn't hurt to know
Just in case if its a off brand or something and it turns out to be a fake other people know to avoid it

 

1. Backup your currently bricked SysNAND (for safety).

2. Attempt firmware repair with CTRTransfer (Type D9).
