(adsbygoogle = window.adsbygoogle || []).push({}); I used to host but now I am confused to whether or not this is still possible

its never been possible to install custom modified patches via USB stick onto a updated system.
the only way to host now is:
E3 Flash
Data transfer some another ps3 with a modified patch already on it
buying a 3.41/3.55 playstation 3

so you need two playstations to host? I have hosted with only a USB before 1.11

Yes U Need 2 Ps3 Now.
