PSP homebrew coder DeadZone has just dropped by the QJ.Net forums to release DeFlasher Re-Edition v3.0 (English) for the community's perusal. This application allows PSP users to flash their PSP's themes and RCOs, among other functions. The author states that this latest app update extends "mod" to "mod29", and carries the recently released PRXFlasher Edition v1.0 app (Tested up to 3.03OE).

Just make sure to view the file README for usage instructions - mishandling flasher apps for the PSP can and will lead to bricking incidents. Also make sure to pass by the application's forum release thread for further related discussions, and usage feedback.
