It has been reopened to the public!
As a result, Lofree Flow Lite is compatible with Windows /macOSX, but until then, the only keymap change application available was Lofree Keymapper, a Windows-only local application, which was not convenient for Mac users. Lofree Flow Lite is compatible with Windows /macOSX.
This is where the “Web-based Keymap Change Application” came in on July 22.
However, it had a serious bug in the release stage and was suspended as of the end of July 2025.
KawamuraThe problem was fatal: if we tried to change the keymap without skipping the firmware update, the firmware itself broke down and became unusable. (A recovery solution was later presented.)
In response to this, the bugs have been fixed in this re-released version.
As we proceeded in order, we found a new statement.

I started the update with trepidation and…
It appears that the update was successful.
