{{#seo: |title=Switch Homebrew Apps (Payloads) - GameBrew |title_mode=append |image=DowngradeFixerSwitch.png |image_alt=DowngradeFixer }} DowngradeFixer is a streamlined bare-metal payload designed to fix issues encountered when downgrading Nintendo Switch firmware from 21.0.0 to 20.5.0. It performs two critical operations without booting into Horizon OS. DowngradeFixer automates two essential steps needed after downgrading your Nintendo Switch firmware: * Dumps prod.keys - Extracts encryption keys required for various homebrew tools * Deletes file 8000000000000073 - Removes the problematic save file from the SYSTEM partition that can cause issues after downgrading See [https://github.com/sthetix/DowngradeFixer/blob/main/README.md readme] for usage. == Features == * Automated Fix - Performs both key dumping and file deletion in one operation. * Silent Key Derivation - Keys are derived and saved without verbose output. * Flexible NAND Selection - Choose to fix SysNAND, EmuNAND, or both. * Safe Operation - Validates each step and reports status. * No Horizon OS Required - Runs as a bare-metal payload for maximum compatibility. * Multiple Reboot Options - Launch Hekate, custom payload, or power off. ==Screenshots== https://dlhb.gamebrew.org/switchhomebrews/images/DowngradeFixerSwitch-01.png ==Changelog== '''v1.0.1''' * Changed the UI orientation to landscape. * Applied cosmetic enhancements using the same color nuance as TegraExplorer-Ext and Lockpick_RCM_Pro. * No new features added.
