Troubleshooting Kindle PW3 Accidental Update

Gazebowe · 02-21-2021, 10:43 AM

Hello all,

Apologies in advance if this has been asked already. I searched for an answer before registering but found no useful threads.

I've got a PW3 that I jailbroke a few years back, and I've been using KUAL and KOreader for EPUBs and the occasional PDF. Yesterday I took the Kindle off of airplane mode for the first time in a long time to browse books on the store. I accidentally left airplane mode off as I ran some errands and the device automatically updated to 5.13.4. As such I can no longer access KUAL. I tried working my way backwards on the jailbreak guide to see if I simply needed to reinstall KUAL or something small, but it seems the update may have removed my whole jailbreak.

From what I can gather these new updates require some sort of soldering job to jailbreak again. Am I SOL?

Thank you!

Hello,

I followed that post by downloading the emergency-bridge-recovery zip and putting it into root. When I typed ;log r , nothing happened and the files did not disappear. However, after a reboot the files DID disappear.

I moved onto the JB hotfix, but when I copied the install .bin into my root, it gave me the following message: Update Error - An invalid update file has been loaded on your device.

Update mrpi and try to install the hotfix via mrpi.

Is there a command for that? Any time I load an update .bin onto the kindle, it gives me the "invalid update" message and deletes it before I can use it.

- copy MR Package Installer to the device
- copy the hotfix.bin to the mrpackages folder
- enter ;log mrpi into the search

I did that, then I also did the same with the KualBooklet hotfix.bin

I got all the functionality back. Thank you very kindly for your help here!
