Originally I was using the latest nightly to get past the error code when trying to go online but then I noticed that my DS flash cart (R4i Gold Clone - Deep Labyrinth) and other legit DS games won't boot. So I saw that a new version was released today (v5.5) and thought that would fix it but it didn't. They worked just great with v5.4 so I'm not sure what I'm doing wrong. Haven't touched the TWL or AGB firms and GBA VC works perfectly. I did downgrade the DS white list. My system has A9LH with latest updated sysNAND. Thank you for your time.
