B)1 3DS Method:
Before doing this, be sure that Your banned 3DS did a System Transfer before, if not, this will not work.
So let's go:
1) Open Decrypt9 on your 3DS, go to SysNAND Options>System File Dump and do the two following procedures: Dump LocalFriendCodeSeed_B and Dump movable.sed;
2) Now open your SD root on your pc, and get the 2 files you just dumped in the files9 folder;
3) Open HxD (download it for yourself) and open both movable.sed and FCSL_B;
4) On movable.sed, copy everything except for the first 8 bytes and the last 40 (for dummys, use the indexes, you can start copying from row 00000000/ col 08 until row 00000110/ col 07);
5) Open LFCS_B, press ctrl + A, then paste your code (it must be and different code than before, if not, see step 7)
6) Now just go to Decrypt9 again and inject back the LFCS_B that you edited and you're good to go.
Can I use this method with the file which i obtained when i installed A9LH on my New 3ds?
Emergency local friend seed
Emergency movable.sed
Thanks in advance.
