Unless you're okay with the possibility of getting a brick, I wouldn't try it. Someone was brave enough to test it on a KT4 and the diags bricked it.

Nevermind.

Thank you guys so much for your explanation! I really appreciate your work to help others!

I followed all the steps, and I think I JB my PW4. The Kual document appeared on the home screen, and that's great, cuz I didn't brick my Kindle.

The only problem is that I don't know what to do next. I try to put the .bin files (Python, Screensavers hack, font hack, etc) into mrpackages folder, and then I open the Kual to install them, but after loading nothing happens
Am I missing something?

I just went through the process and it worked ok. I had a little bit of trouble with screensavers as I didn't install python 2.7 first.

Did you try the ;log mrpi method? Does Kual show any entries for the screensavers hack? Are the bin files still in the mrpackages folder?

KUAL is just a menu to launch stuff from. You have to go to Helper -> Install MR Packages to actually install stuff. Or as mentioned in the post above, ;log mrpi in the search bar works as well.

Personally, I do the install for all add-ons in one step. Directly after installing the hotfix, I copy all the packages I need (KUAL, python, screensaver, etc) to the mrpackages folder and just run ;log mrpi to install everything in one shot.

I actually mentioned this in the instructions.

Step 10. Install MRPI and KUAL.

e. (Optional) You can also copy the various update*.bin KUAL Add-On packages to the mrpackages folder for installation at this point (e.g. python, linkss/screensaver, etc).

Yes, you're right! The instructions were very well explained, and I followed them as if they were in the Bible xD
I think my problem was that I used the bin files from the list that says"Packages targeting the Kindle 2/DX/DXG/3/4" and it should be from the "Packages targeting the Kindle 5", right?

Thank you again!

[j.p.s]

The Kindle 2/DX/DXG/3/4 are very old with different hardware.

Kindles have been Kindle 5 for a long time.

I didn't know that, it's the first time I hack a kindle. But it worked! Thank you again. I only have 2 more questons:

1- How do I change the screensaver now?
2- Is there a bin file to make the kindle read .cbr files?

1. Check the readme file or something from the linkss/screensaver package. There are descriptions and instructions for the various modes available there.

2. KOReader supports CBZ (zip) files but not CBR (rar) as I recall. That said, it's very easy to convert your CBR files to CBZ since these are basically renamed ZIP/RAR archives which contain a bunch of images. You'll want to use the KOReader kindlepw2 version for your PW4.

To be perfectly honest, it really was more blind luck than work.

is it possible to downgrade from 5.13.4 to 5.13.3 and then to jailbrake?
