I have just bought a Sony prs-300 and would like to change the text so it is left justified. Reading through the forum it looks like I can do a flash similar to the prs for the 505. I am not sure how to do this as there is no sd card. Also, someone mentioned the original 300 firmware to get it back to factory version but the link they had is megaupload which disappeared years ago.

Does anyone know where I can download this.

Can any kind soul please give me a 'prs-300 flashing for dummies' list of what I need to do, and how to get it back to original if anything goes wrong.
