Merry Christmas to everyone!
I have PW4 5.13.2. I followed all the steps described by @ilovejedd but I don't seem to create/manage collections using Calibre. I receive the same message as before, when I hadn't the jailbreak.
What I think I did wrong. At step 9, I downloaded

and I flashed and I continued to step 10. Maybe I should've go back to step 1 again after flashing the 5.11.2 version?
