Big
to coplate, knc1, NiLuJe, Branch Delay, et. al. without whom this wouldn't be possible.
I'm copying most of knc1's instructions from the
PW3-4, PW3-32, fw-5.8.9.0.1 software jailbreak as the steps are more or less the same.
Note, for extracting the packages on Windows, I recommend
7-Zip.
Tested working on both new and OTA updated PW3 running firmware 5.9.6.1 or older. Initial testing was performed on a brand new, out-of-the-box Paperwhite 3 with 5.9.6.1. For OTA updated PW3, tested on both
5.9.2 and
5.9.6.1.
There is always a chance that you could brick your device. Use at your own risk.
Instructions
You should block any OTA updates before allowing the device to connect to the Internet.
To prevent OTA updates, add the OTA blocker directory (folder) name to the top level of visible USB storage.
The blocker directory is named: update.bin.tmp.partial
Use that exact name, no additional extension, no contents.
Instructions are the same as on wiki unless specified:
https://wiki.mobileread.com/wiki/5_x_Jailbreak
Note: On fresh, out of the box Kindles, don't factory reset.
Read the above cautions and take note of the warnings on the wiki.
Read the current jailbreak, with the exceptions you decide to make based on the above cautions, skip to step #4.
Step #3-4:
Download and use this file:
update_pw3_5.9.6.1_factory.bin

This will "update" (
"update" is the label on the button, not the action) your firmware from "customer" to "factory" 5.9.6.1. This process can take several minutes (should be less than 1 hour, though).
Step #5:
Same as wiki.
To be safe, use the latest version of
main-htmlviewer.tar.gz from
NiLuJe's Snapshots thread.
As of writing, that's:
On Windows, you'll probably first need to extract
kindle-jb-factory-1.2-r15011.tar.xz to get the tar file and then extract the resulting
kindle-jb-factory-1.2-r15011.tar to get the
main-htmlviewer.tar.gz file. Then just follow instructions on the wiki.
Note: You'll probably need to do this double extraction for all packages from NiLuJe's Snapshots referenced later in this post.
Step #6:
Same steps as wiki, use this file:

Step #7:
Install "customer" firmware build. You probably can't downgrade below 5.9.6.1. If you want to play it safe, I believe sticking to 5.9.6.1 will keep this jb method open:
update_kindle_all_new_paperwhite_5.9.6.1.bin
update_kindle_all_new_paperwhite_5.9.7.bin
Step #8:
Install MRPI and KUAL. This is pretty much the same method as PW4. A bit trickier compared to 5.8.x since Amazon dropped Kindlet support (azw2 document).
- Download the latest MRPI package from NiLuJe's Snapshots thread and (double) extract.
As of writing:
- Copy the extensions and mrpackages folders to the Kindle root (alongside the documents folder).
- Download coplate's KUALBooklet build (KUALBooklet-coplate-d20a095-20181108.zip) and extract.
- Copy Update_KUALBooklet_d20a095_install.bin to the mrpackages folder on the Kindle.
- (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).
- Eject and unplug the Kindle.
- Enter ;log mrpi in the Homescreen's searchbar (in a similar fashion as what you had to do during the Jailbreak), and wait for MRPI to do its thing.
