If you're not, you're out of luck, at least not without hardware modifications, which we only know how to handle on *some* specific models (generally, older/simpler ones).

I am stuck. I downgraded to 5.10.1.3 -- Thank you very much for your help @ilovejedd

I installed jailbreak, I installed JB Hotfix, I extracted the MRPI folders/files... This seems to be all good... But I am having trouble with next step, install KUAL

I copy Update_KUALBooklet_f54e864_install.bin to mrpackages and search ;log mrpi

Nothing happens... So I restart device, and nothing happens

Where does KUAL.cfg file go?

Thanks

The KUAL installation is not working for me

ilovejedd helped me to downgrade my PW4 to 5.10.1.3

I have had success to the jailbreak and hotfix install and have copied the mrpackage folders/files to the device. No problem until this point.

I tried to Update_KUALBooklet_f54e864_install via ;log mrpi -- but nothing happens after I press search

I tried to Update_KUALBooklet_hotfix_f54e864_install via Update Your Kind -- but it does not work and I see this message "Update Error. An invalid update file has been loaded on your device. Please contact customer service."

To start over fresh, I have performed the diag and downgrade procedure twice. Still KUAL does not install.

Can someone shed light? Thanks

If *nothing* (and I do mean *nothing* at all) happens with ;log mrpi, but the JB hotfix install via UYK was actually *successful*, you've simply botched the MRPI install.

The KUAL hotfix is not designed to be able to pass the safety checks on FW < 5.12.2, so, that failure, at least, is perfectly normal.

Sidebar: pairing a post with a perfectly identical PM will not win you any points. Don't do that.

@seymourtv, so you can try to upgrade to 5.12.4 after the hotfix and then play with the KUAL installation.

Thank you @hius07

The solution for me was 1) update to 5.12.4 and 2) use Update_KUALBooklet_hotfix_f54e864_install + Update Your Kindle

Sorry for multiple posts. Moderators please delete if you deem necessary.

Cheers

That won't fix a botched MRPI install, though.

The JB hotfix is (mostly) completely orthogonal to MRPI, so, it won't magically make MRPI run if it's not installed ^^.

I am trying to jailbreak a PW3 that updated to 5.12.4

I factory reset the PW3

I found "update_pw3_5.9.6.1_factory.bin" which is the correct factory image for my PW3. After I copied the .bin to device root, I see this message "Update Error: An invalid update file has been loaded on your device"

Is there another I should be using?

No you can't. 5.9.6.1 is the last jailbreakable firmware.
