For downgrade from Rogero v2 to 3.50 I used qa_flag.pkg and qa_flag_extra.pkg.After U qa_flag Your console U should see two more setings in System Update.If U have qa_flag Your PS3 U should downgrade without any problems.

1. Install CFW355-OTHEROS++-SPECIAL.pup (Doesn't matter what version you are. 3.55 and lower ONLY.)
2. Install qa_flag_extra.pkg 
3. Run qa_flag (It will show up as this, that is fine)
4. If you hear the beeps, continue. If you do not hear beeping, come to irc.
5. Reboot
6. Go into recovery menu and Update your ps3 with the firmware that you want (3.15, 3.41 etc)
7. have it install

This is example for 3.55 OtherOS but should works on JFW 3.56.
