There’s something I don’t understand why Sony updated its Playstation Portable 5.51. But here it is in plain and simple sight… the updated version of the PSP Firmware 5.51.
I deduce nothing extraordinary with this update, just a couple of network passes we couldn’t do before. There’s the same old nonsense; and an improved system software stability during the use of some features. Aside from that, I couldn’t see anything special with the updated Firmware 5.51.
If you’re the hacked but Pandoraless, PSP 3000 or TA-088v3 type, I wouldn’t recommend updating your firmware to the 5.51. There are more important applications for your memory sticks to exhaust itself with.
