Anyway, the most annoying thing in all this is that my PS3 boots in JB mode only 1 time from 10. Usually my phone shows everything like in Youtube guides but my TV just stays blank and PS3 doesn't boot up. Does anybody have same problem?
Hermes patch didn't let me play games without disk anyway (got error while clicking on the folder in XMB) and I could not run most games (crashed, didn't start at all or got my PS3 unresponsive). Now I've got almost all games working (except Heavy Rain and Assassin's Creed II) by going back to original files and playing with disk!
