Who has Infectus2 on his PS3 and downgraded it yet?

[NDT]

Hi, i'd like to know if someone with Infectus2 have ever downgraded his console with an old backup of the firmware.

Infectus2 is a bit different than original version:



If someone did it please write here:

- Software used (e.g. Infectus Programmer 0.0.3.4).

- Version before and after the downgrade (e.g from 2.30 to 1.80)

Thanks a lot.
