Update to 4.x with one of these (http://www.eurasia.nu/wiki/index.php/3DS_Games_with_firmware_updates_in_the_4.1_-_4.5_range) then https://github.com/Plailect/Guide_RedNAND/wiki/9.2.0-UpdateSo my cousin downgraded my new 3ds to 2.1.0 how to get back up please help
Is that the only way ?
It should, yeah. The problem here is that 2.1 cant be directly updated on n3ds or it'll brick, so you need one of those carts and disable wifi, then try to run it and it should update.Does it work on new 3ds ?
Ok thanksIt should, yeah. The problem here is that 2.1 cant be directly updated on n3ds or it'll brick, so you need one of those carts and disable wifi, then try to run it and it should update.
... why would you do thatmy micro sd card was also formated
YesWas he following the 3ds.guide?
I dont know why my cousin did... why would you do that
Is there any section on the guide telling to format the SD card after downgrade?
can you explain how can I get back to 11.2DO NOT USE A CART UPDATE. This will either brick or severely cripple your N3DS.
@Plailect had some method of restoring CTR mode here (though TWL will remain bricked).
I don't know the exact process; that's why I tagged Plailect.can you explain how can I get back to 11.2
This is missing the extra steps for N3DS (needs an N3DS NCSD header and key slot 0x05 crypto). I'm not sure how to do that with ctrtransfer.
Are you sure this works ?
He didnt ask he just did while I was awayI don't know the exact process; that's why I tagged Plailect.
Incidentally, did your cousin ask you about downgrading, or did he do it on his own? And why did you think it was a good idea to firmat the SD card without copying the NAND backup and other files off of it?
