I'm not sure if it breaks anything but I made the same mistake and the following worked for me.

1) copy the following lines from \renameotabin\bin\restore.sh [open with a text editor]

cd /usr/bin
mv otaupd.bck otaupd
mv otav3.bck otav3


2) Open jb.sh from WinterBreak, scroll down to the end and paste the 3 lines right before "mntroot ro" located 4th line from the bottom. Save and close and run the first stage of Jailbreak and the issue should be fixed.

Also, KOReader from https://fw.notmarek.com/khf/koreader/ fixed my issue with "failed to start application" error

I messed up installing the jailbreak.
Kindle Paperwhite 11 firmware 5.16.2.1.1
It looks as if the Internet was turned off, but I am sure that I turned it on and started uploading the modification as soon as possible. The worst thing is that in the madness of looking for a solution, I overwrote the backup copy with a modification
After uploading and restarting, I cannot run airplan mode and updates. Everything is greyed out. Trying to repeat the steps does not help because after reaching the power on screen, the computer does not see the Kindle partition. Is there any way to restore functionality and install a jailbreak?

Thanks for this, looking forward to jailbreaking my Kindle!

I have Oasis version 3 - and stopped connecting it so I am on version 5.16.8. Would you recommend I upgrade to the latest 5.17.1.0.3 before doing the jailbreak?

Hello widyanirwadi, I have had the exact same problem as you, and I already have the Marek's koreader nightly build file but I don't know how to install it, because it is a .targz file. I will appreciate if you could tell me how to install it?

If you're on Windows, use 7-Zip to extract the files. Or alternatively just rename .targz to ".tag.gz".

Inside "koreader-kindlehf-v2024.11-124-g82eaa0098_2025-01-03.targz" archive there is a single file "koreader-kindlehf-v2024.11-124-g82eaa0098_2025-01-03" with no extension. It's actually a "tar" archive. You can add an extension to it, so it becomes "koreader-kindlehf-v2024.11-124-g82eaa0098_2025-01-03.tar". Extract it again, you'll get two folders:
* koreader
* extensions

Just copy those to your Kindle (when PC asks if you want to merge, since "extensions" folder already exists, say "yes").

5.17.2 Kindle Scribe 2022

I have tried a factory reset. I dont see a LocalStorage directory on my device to delete per the instructions. I am using MacOS and the Kindle USB Manager app with this

delete the cache directory at the path .active_content_sandbox/store/resource/LocalStorage (Skip this step if the LocalStorage directory does not exist)

I have the same exact model and firmware, worked for me. Since you're on MacOS, I think your problem is that you didn't copy all the files to your Kindle, since MacOS by default hides all folders / files that start with a dot (like ".active_content_sandbox"). Enable "show hidden files" in both MacOS and OpenMTP and start from scratch, following the instructions.

I've now done this on two devices, both PW5 Kids, both with a fresh upgrade to 5.17.1.0.3 before the jailbreak. Some notes after having the same experience on both devices:

1. When accessing the store, on both devices the Kindle actually did a store update and didn't run the jailbreak. On the first device I followed the troubleshooting instructions and did a factory reset, but on the second device I merely deleted the cache directory at

.active_content_sandbox/store/resource/LocalStorage

and (perhaps redundantly) copied over the .active_content_sandbox directory from the WinterBreak folder again and rebooted. The second time, the store executed the jailbreak code. Perhaps the instructions should recommend opening the store first so any pending updates happen, and then enabling airplane mode and installing the WinterBreak code after that.

2. As in this comment I also have a new KFT item under settings that appeared after the jailbreak. It didn't appear on the second device until after the jailbreak (I checked).

3. When MRPI is done installing packages and says "Done, restarting UI . . ." the Kindle displays an Application Error dialog with the text "The selected application could not be started.
Please try again." I've been restarting the Kindle at this point but I don't know if that's necessary.

For me the store is always updated, regardless of whether it's the Kindle
was previously set to factory settings, or not, no matter when and how often

.active_content_sandbox/store/resource/LocalStorage

overwritten or deleted.
Kindle to factory settings, as soon as available as a USB device in Windows, Winterbreak copied to the Kindle, then logged in with the Amazon account, Wifi off, again

.active_content_sandbox/store/resource/LocalStorage

overwritten, reboot, start store and it is updated and that's it, no winter break to be seen. Even if I copy Winterbreak again, reboot etc, the store is updated and nothing else.
I have no idea what else to do.
This on a PW7 with FW 5.16.2.1.1

There is no such Kindle as a PW7. The latest is the Paperwite is the PW6 (2024).

[re4om]

successfully installed winterbreak 1.3.0 with 1.8.0 hotfix on kindle 10 gen (5.16.8 firmware) and kpw4 (10 gen) 5.16.9 firmware. But every time I deleted file like "update.bin.tmp.partial" of new firmware that started downloading every time when connected to the Internet. Then installed "Update_KUALBooklet_ALLDEVICES_install" by Update you kindle and KUAL works perfectly.

I fixed it in a simple way :
I cleared the WinterBreak files.
Then:
;enter_demo
;demo
Wifi settings - I completed everything and wifi started working.
Resell device
Then everything started functioning normally
Tomorrow I will JailBreak after updating the reader.

I have a PW5SE on 5.17.1.0.3, and have never been able to get the hotfix to work. Which version of Winterbreak and the Hotfix did you use?

However, it is displayed this way in the device information.
Ultimately, it's irrelevant if I made a mistake with the device name, that won't be the reason why it doesn't work.

reporting in for stats, any help

Kindle PW3 v5.16.2.1.1

Great to use Jailbreak for using epubs too. I have kindle OaSis 4G. Just in case, If it should not work, how may I reset to manufacture Software?
