Older GEN Custom Firmware like the 5.50 GEN-D3 had a protection to avoid updating to Official Firmware and lose Custom Firmare. This protection works by replacing the version.txt file in flash0 to an absurdly high version number, 9.90, which is giving you the "system version is 9.90, no need to update".

Multiple homebrews can restore the original version.txt, allowing you to update to 6.61 Official Firmware. In this guide, we will use the Version.txt Switch & Repair homebrew.

Get started
