I think I installed it wrong and it leaves the console with the black screen. I want to remove it but it doesn't have this button, and it was permanently installed on xmb, even reinstalling the software
Wow, that's very much not supposed to happen, and if anyone would ask if that was possible I'd tell them "no, impossible, don't worry". But since it happened to you, who knows how (the app doesn't change anything big. Only small stuff), go to the Discussion. There we can talk if you need.
But to remove the app all you have to do is go on Game Data (think this is the right name), find HAN Toolbox there, Delete it, and reboot the PS3.
If you reinstall the FW, the toolbox should be gone from the XMB but the data should remain there (unless you manually delete it).
To install the toolbox, you just enable HAN or Debug PKG and install it, just that (one or the other depending on the installer you got).
Do you still need help with this? Sorry, I had not come here for some time.
