I see commits from as recently as yesterday regarding HF support, so I was planning to just wait to see if it's still broken for me when those dry up.

I just tried the https://fw.notmarek.com/khf/koreader/ link and it automatically downloaded the koreader-kindlehf-v2024.11-124-g82eaa0098_2025-01-03.targz file. Opened it with 7-Zip (right clicked, 7-Zip => open archive) and looked okay to me.

Hi there, trying to figure out what to do about my Paperwhite 10 not being able to get past the "Kindle store encountered an unexpected error" issue. I used 7Zip to open the exploit files, copied those via Windows 11 to my Paperwhite 10's root directory, continued following steps, and got the above error when I tried loading the Kindle Store. Factory reset, tried again using troubleshooting steps, same error message when I load the Kindle Store. Unsure what else I can check/do? Thanks in advance for any help.

Oh nice, it's been updated. Thanks. Earlier it was still pointing to an old build and giving a 404. Based on the name, it may be the same as the current official nightly build, but I'll try it when I get home.

Did you see the Mesquito loader and the jailbreak text output when visiting the store? If not, you'll need to make sure you properly copied all the files and that the .active_content_sandbox/store/resource/cachedResources/index.html file on the Kindle is the same as the one in your local WinterBreak folder.

If the jailbreak ran, make sure you're putting Update_hotfix_universal.bin in the main directory of your Kindle (not a subdirectory), that you haven't disabled OTA updates using something like renameotabin, and that you're installing the hotfix using the standard "Update your Kindle" option in settings.

Yes, I do see Mesqito and the Jailbreak text. I have gotten KUAL running, but KOReader is failing to start. But, since my understanding of the hotfix is that it persists the Jailbreak across updates, and if I have disabled OTA updates, I think I should be safe?

I have a Kindle PaperWhite 10th Generation (PW4) and i've tried the latest WinterBreak.
When I enter the store, it says "Unexpected error" or other messages like that. I have followed all the steps, I tried the trobleshooting method, I tried putting the Kindle in multiple regions, I reset it like five times in one day. I have tried everything possible and even impossible. Please, if anyone knows how to solve it, I need help.

(sorry if my English is not good)

Just confirmed, that new build from notmarek does work on my PW4. It's a different compile, with many of the binaries differing, despite being based on the same commit (according to the filename). I guess I'm pretty much good now. Thank you!

Still curious whether there would be any advantages to downgrading my FW to a non-hf version. All things being equal, an hf-targeted FW should be faster, but of course it depends on what else they added at the same time and other factors. I'm happy enough on this firmware now though. Thanks again!

Im Currently on a Kindle Scribe, and have successfully gotten the jailbreak to work. But the issue i am having at the moment is that when it ask me to install the hotfix, I try to transfer the file over to the device, assuming the file does transfer over since I don't actually see the file in the directory. I try to update the Kindle from the settings while OTA is off, I get nothing in terms of it working nor does ;log mrpi work. So am i doing something wrong, or is it still just a bug for kindle scribes. I haven't heard much luck in terms with he Scribes in here.

I have also Factory Reset the device, updated the device. I'm just stuck.

How do I remove it? I tried it out but I don't think its worth it. How can I remove it?

Sorry but how do you even know the file transferred if you can't see it on the device? After you copy the file over and safely eject your Kindle, when you look in Device Options, under Software updates, do you see anything indicating that an update is available? For me, I saw a line reading Software updates with Update your Kindle to the latest firmware with Update at the end of the line? When I tapped on Update >, the hotfix was installed.

Do you have OTARenamer installed? If so, did you use it's restore option before attempting the hotfix?

I do not have OTARenamer on the device, the only thing i have done to he device is send over he WinterBreak Exploit, Restarted the device, then i Opened up the Store and the jailbreak did its thing. Next it ask me to install a hotfix, I then proceed to connect my device back to the Computer to transfer the hotfix to the device root and Disconnect the device from the pc. then I go to settings and look for the update which tells me i am currently on the latest update. So i dont have an option to update.

P.S. i Appreciate you helping me out i have been frustrated with this for almost 2 days now.

Have you tried restarting your Scribe from Settings => Device Options => Restart after copying the hotfix .bin file to the root of the exposed storage? I seem to remember someone mentioning that they had to restart to get the hotfix installed since it did not show as an update being available but it did install on a restart.

Hi friends,

I previously successfully jailed break the device then install the KUAL and disable OTA, but KOREADER did not start so I tried again and again.

I tried to factory reset, then with Amazon store I can jail break it again but
I am stuck with step Copy Update_hotfix_universal.bin now, I cannot update the hot fix anymore as it always say I am at the latest firmware version (maybe a factory

Please advice me if you have information. Thank you so much.

Note:
I'm using Kindle Paperwhite 5 (Kids version) 5.17.1.0.3

[tekkasit]

@carp, your situation is exactly like mine, just with a different process (yours involves the "scanner", mine involved the "KFXReader").

Don't do something you will regret, like me.

DO NOT factory reset your Kindle.

First you have to check the Three dotted menu when you first pen up the Settings menu. Normally it would say Restart, shutdown. But now there will be an option the Update your Kindle. then it should run the update and then restart. Once it does there will be a Hotfix (book) in your library now. Run it, if you're in a loop of resets, then you will have to do option B.

Option B: So what you might have better luck doing is downloading the latest KUAL (Coplate), Extract only the Update_KUALBooklet_hotfix_*_install.bin and put it into your main directory like you do for the regular hotfix. and make sure you delete the hotfix that originally have on there. Disconnect and Eject the kindle, and run the update again. you should have the KUAL (book) iinstalled
