FTF stands for Flash Tool File . It is a proprietary file format used by Sony Xperia devices.

With the right FTF file and careful execution, your C6903 can be returned to a fully functional, lock-free state within 15 minutes.
Welcome to Retrosheet
Retrosheet was founded in 1989 for the purpose of computerizing play-by-play accounts of as many pre-1984 major league games as possible. Retrosheet's work has expanded considerably from its original inception while retaining the same core focus: major-league games. Read more about our organization and our history here.
Retrosheet's goal today is to provide as much information as possible about every baseball game played in major-league history. The results of our work can be explored through the menu items above. An overview of the game data we have available is summarized below. To return to Retrosheet's home page (i.e., this page), simply click the Retrosheet bat from any page.
Retrosheet is an all-volunteer organization. We are always looking for more volunteers. If you would like to help us with any of this work, please reach out to Retrosheet's President, Tom Thress, at tthress@retrosheet.org. We are also funded entirely by donations. If you would like to make a donation, the details of how to do so can be found here.
