007 error when installing hotfix

So, my kindle updated to 5.12.2 a couple months ago and I thought I had lost my JB. Until now...

I've found this post: https://www.mobileread.com/forums/sh...d.php?t=325477

Followed its instructions and now it seems like my JB is working again. I can open KUAL and stuff, then I went to install the hotfix so I could avoid losing it again, but I still get the 007 error.

I thought about re-doing it, using the ;merchant command, but maybe this could lead to bricking it.

So, how should I install this hotfix?


Thanks!
