Depanbrew is a homebrew application that, according to its french author, is supposed to “solve every type of encountered problems” – which is obviously a mistranslation. Currently, it presents two selected problems commonly attributed to the installing of out-of-region firmware updates (duplicate channels, and an unaccessible settings menu) as well as a simulation of a repair process. The application does not actually repair anything, but it looks pretty in the process.
