Omiiba3DS v1.4.9 Alpha - OTA Safety Fixes

Omiiba3DS v1.4.9

Omiiba3DS is an unofficial fork of Luma3DS, rebranded for educational purposes. Firmware functionality is upstream LumaTeam work; see NOTICE-OMIIBA.md.

Alpha warning

This is an alpha / pre-release build. Keep a known-good boot.firm backup on your PC or SD card before testing OTA firmware updates or experimental retro features. OTA updating is handled by HOME Menu/Homebrew Launcher apps, not by the arm9 bootloader.

What is included

• Omiiba Boot Hub: SELECT opens the Hub first, with fast Continue normal boot, explicit Save settings and boot, setup wizard, advanced settings, diagnostics, profiles, payload manager, theme/settings, GodMode9 tools, GBA Labs, DS Labs, DS Widescreen Labs, VC Patch Helper, and Wireless Tools.
• Setup wizard and profiles: guided safe defaults for splash, brightness, game patching, external FIRMs/modules, GodMode9 placement, plus named presets for Default, Safe, Performance, Plugin/Game Modding, and Developer/GDB.
• Diagnostics: read-only checks for config, GodMode9, payloads, GM9 scripts, SD/CTRNAND boot.firm, EmuNAND, setup wizard marker, open_agb_firm, DS/TWiLight paths, VC patch folders, widescreen files, and OTA helper paths.
• Payload manager: lists and launches .firm payloads, explains hotkey naming, and can create non-destructive hotkey copies.
• GBA Labs: bundles and launches open_agb_firm, writes SD-only display presets for /3ds/open_agb_firm/config.ini, checks GBA setup files, and keeps deeper AGB_FIRM scaling/filter and GBA VC display patching clearly marked as research.
• DS Labs: bundles TWiLight Menu++ / nds-bootstrap files, checks common DS setup paths, guides CIA installation, and can create the recommended SD:/roms/nds/ folder.
• DS Widescreen Labs: manages the existing TWL external filter setting, checks twl_upscaling_filter.bin, checks the bundled widescreen compatibility list, creates setup notes/folders, and documents the limits around per-game widescreen codes.
• VC Patch Helper: checks game patching status, creates the SD:/omiiba/titles/0004000000000000/romfs/ template, and documents LayeredFS, IPS, BPS, code, exheader, locale, and RomFS patch layouts.
• Wireless Tools: prepares and checks paths for Omiiba Updater, Universal-Updater, the bundled Omiiba UniStore, CIA placement, and ftpd without trying to run Wi-Fi networking in the bootloader.
• OTA updates: includes SD:/3ds/OmiibaUpdater/OmiibaUpdater.3dsx for direct latest boot.firm downloads from GitHub releases, plus SD:/3ds/Universal-Updater/stores/omiiba.unistore for Universal-Updater.
• Updater safety fixes in v1.4.9: the Omiiba Updater now rejects obviously wrong boot.firm download sizes and attempts to restore the previous SD:/boot.firm if the final install rename fails. The UniStore now stores temporary zip downloads at the SD root so it does not depend on nested folders existing first.
• Release assets: this release publishes Omiiba3DS-v1.4.9.zip, standalone boot.firm, OmiibaUpdater.3dsx, and omiiba.unistore.
• Version string: firmware reports v1.4.9.

Install

Extract Omiiba3DS-v1.4.9.zip to the SD card root. For OTA updates, launch SD:/3ds/OmiibaUpdater/OmiibaUpdater.3dsx from Homebrew Launcher, or use Universal-Updater with SD:/3ds/Universal-Updater/stores/omiiba.unistore. If you only want the firmware update, copy only boot.firm to the root. boot9strap required.
