Moved to the PS3 Mods Questions and Inquiries section.

You can not install custom firmware on any firmware above 3.55 so that's why it's not installing. Try going into recovery menu and installing 4.41 official firmware (since there is no point going back to 4.20 because you CAN'T install custom firmware on it! If you can't get into recovery I think your only way is with a flasher.

What about my other ps3

No Idea, is it on cfw?

im not sure
