I got a 2504a it was working well until hard disk failures occurred and the software corrupted. Replaced the hdisk and now I try to install the software again, current version of software is 4.21. I can't find the 4.21 file anywhere. Tried an 4.46 version custom file but ending up with black screen.Sponsored Links
After reformat the HD, the ps3 still ask for 4.21 or higher. I am not sure if this can be done with an custom made PUP could use some help with this !!
Thanks in adv. Roel (European version) not sure if people need this information
