Restore-LFCS_B is a Godmode9 script that attempts recovery of the console's LocalFriendCodeSeed_B file. This script is intended to be used in the event a mismatched or malformed LocalFriendCodeSeed prevents the use of online services such as Pretendo.
Required Reading
This script is only meant to be used if certain errors occur when attempting to use online services, these being error 002-0121 on both Nintendo Network and Pretendo, or 002-0150 (custom Pretendo error), which are often accompanied on Pretendo by error code 022-2402 on services utilizing Nintendo Network IDs.
Error code 002-0121 indicates the LocalFriendCodeSeed signature is invalid. However, on Pretendo this can indicate the patches aren't being applied correctly. Ensure Luma3DS is on version 13.0 or higher, the Enable loading external FIRMs and modules and Enable game patching settings are both enabled, and that the Luma3DS configuration menu states Booted from SD via B9S. If all Luma settings correct, attempting to reinstall Pretendo may help in case the patches are broken. If after checking the Luma settings and reinstalling Pretendo the error still appears, or if the error occurs on both Nintendo Network and Pretendo Network, this script will be needed.
Error code 002-0150 indicates the LocalFriendCodeSeed doesn't match the console's serial number. Upon connecting to Pretendo, the console sends both its LFCS and serial number to the server. If the LFCS is already associated with a different serial number on the server, or the serial has been used with a different LFCS, then this error will appear and this script will be needed.
