Reset Blocked Users on Nintendo 3DS? No Bulk Option—Must Unblock Individually or Factory Reset

There is no "reset blocked users list" or "unblock all" button on Nintendo 3DS. Once blocked, users stay blocked until you manually unblock each one—or you nuke the system with a factory reset.

Method 1: Manual Unblock (Safe, Tedious)

1. Open System Settings (wrench icon) → User Settings (Mii face) → Friend List.
2. Select Blocked Users (orange tab).
3. For each user: Select → Unblock → Confirm.
4. Repeat. No multi-select.

Method 2: Factory Reset (Nuclear, Wipes Everything)

1. Backup saves: System Settings → Data Management → Save Data Backup (to SD card). Not all games support backup.
2. Backup photos: Nintendo 3DS Camera → SD Card.
3. System Settings → Other Settings → Page 4 → Format System Memory.
4. Confirm ×3. Console becomes "new."
5. Re-setup: Language, region, NNID (can relink same NNID), eShop, StreetPass, etc.
6. Blocked list: Gone. Along with friends, activity log, play coins, themes, badges, downloaded games (redownloadable), saves (if not backed up).

What Blocking Actually Does

• Prevents: Friend requests, game invites, messages, Miiverse posts (dead), Swapnote (dead), co-op play.
• Does NOT prevent: StreetPass encounters (Mii data still exchanges), local wireless (same room), seeing them in public lists.

Better Than Blocking: Temporary Measures

• Remove Friend: Friend List → Select → Remove. Reversible. Re-add later.
• Notifications Off: Settings → Notifications → Disable per-friend (not granular on 3DS).
• Just Don't Play With Them: No technical enforcement needed.

If You're Being Harassed

• Block + Report (Friend List → Select → Report).
• Contact Nintendo Support with screenshots.
• Police if threats escalate (Nintendo cooperates with law enforcement).

No bulk unblock. Choose: manual cleanup or factory reset. Backup first if resetting.
