Nintendo Ds System File Missing Code In Its

Otherwise, you will need access to another 3DS that has your old Friend code in its Friends list.

The Friend code alone will not suffice; you need to run homebrew on that other 3DS.) Or you can try to get your old 3DS back from whoever you sold it to, and hope that they havent done a System Format or System Transfer.

Did you even attempt to troubleshoot what caused that ARM11 error in the first place This would be an unfortunate scenario if the problem was due to a fake, faulty, or dying microSD card and not the n3DSXL itself.

Also, you cant System Transfer the Nintendo 3DS folder to your replacement n3DSXL unless you still had the first n3DSXL.

Edit - You might be able to recreate the needed KeyY if you know and can reach someone who has added you before your original n3DSXLs Friend Code to their Friend List.

You will need the encryption key (movable.sed) from your old 3DS.

Unless you kept a backup copy of the (source) n3DSXLs SysNAND.bin image, essential.exefs, or movable.sed, you also wont be able to decrypt or clonecopy the Nintendo 3DS folder to your new (target) n3DSXL with the SDTransfer methods.

Removing the custom firmware usually does more harm than good because whatever softbrick issue that n3DSXL was experiencing is now not repairable unless its rehacked again.

This is assuming (s)he hasnt already erased your user profile from a System Settings Other Settings Format System Memory.

If they already did, theres a slight chance the needed first half of the KeyY (aka, LFCS) is no longer recoverable if that n3DSXL was previously involved in a System Transfer where it was the (target) system receiving the Nintendo 3DS folder from yet another (source) 2DS3DS system.

Without that intact LFCS, theres no way bruteforce the exact KeyY back into existence.

And without that KeyY, everything in the Nintendo 3DS folder is locked away.

Different ARM11 errors often have different underlying causes.

Sometimes, the same or similiar ARM11 errors also have different causes.

However, not all hope is lost if you kept a copy of that folder and depending if the Nintendo 3DS folder was created by that old n3DSXL (did not come from a System Transfer).

If the n3DSXLs too softbricked in its current state, see instead the ntrboot method.
