Tools Introducing WinterBreak - Better Late Than Never

[FelixKrull]

Thanks for your hints. I'll try that. Actually atm Amazon just cannot upldate my device as there is not enough space left for the update file.

I also followed the instructions, switching Airplane mode off and on when indicated. But I guess I have to clear space in order to get it done properly...

Your Kindle must have a valid, internet-connected WiFi network saved to it that it can connect to during steps 8 to 10 (inclusive)

For me it is not entirely clear what is meant by that. Winterbreak goes from 1 to 7, after that it is post jailbreak with 5 steps, and KUAL with 7, then "Disabling OTA Updates".

Should I stay online from step 8 until the "Disabling OTA Updates"?

Factory reset kindle
Select Language and Region
Plug Kindle into PC and copy Winterbreak files
Eject then unplug Kindle
Register kindle, No thanks to "Kid Friendly", No thanks to "Kindle Unlimited"
Turn on airplane mode and plug kindle into computer
Delete folder .active_context_sandbox
Eject & unplug Kindle
Reboot kindle
Turn off airplane mode
Download book from library & Download free book from Amazon Prime Reading.
Go to the kindle store with the Wifi connected and browse around for 10 minutes
Exit the store & let Kindle sleep for 10-15 minutes. (Kindle restarted on it's own after being asleep for a few minutes.)
Plug kindle into computer to check if it is done generating the folder with its files, check the folder .active_content_sandbox > store > resource > cachedresources. (At this point there was still no file called "secondary store" or "index" but "localstorage" was there.)
Eject then unplug kindle
Turn on airplane mode
Plug kindle into computer
Copy the "index" file from Winterbreak AND delete localstorage directory
Eject then unplug kindle & reboot
Open Kindle Store, turn off Airplane mode.

At this point it still did not show up, but then I said screw it and decided to check one last time. I just plugged the kindle into my computer and went to delete the localstorage and I saw that it wasn't there but the "secondarystore" file WAS there. I just copied the "index" file over again, disconnected, rebooted and went to the store and the Mesquito icon was finally there...

I created an account to share that this finally worked for me. I tried all methods, but only this one succeeded. Maybe it will help someone else. Thank you! 🤝

Here’s my process on PW3:

ℹ️ I shared Wi-Fi through the hotspot on my phone.

• Factory reset kindle
• Select Language and Region
• Plug Kindle into PC and copy Winterbreak files
• Eject then unplug Kindle
• Register kindle, No thanks to „Kid Friendly“, No thanks to „Kindle Unlimited“
• Turn on airplane mode and plug kindle into computer
• Delete folder .active_context_sandbox
• Eject & unplug Kindle
• Reboot kindle
• Turn off airplane mode
• ❌ Download book from library & Download free book from Amazon Prime Reading. 💬 I didn’t have any books in the library and couldn’t figure out how to download a free book from Prime Reading.
• Go to the kindle store with the Wi-Fi connected and browse around for 10 minutes. 💬 While in the Kindle store, I checked out various books, read descriptions, and downloaded a free sample from a random book.
• Exit the store & let Kindle sleep for 30 minutes.
• Plug kindle into computer to check if it is done generating the folder with its files, check the folder .active_content_sandbox > store > resource > cachedresources.💬 At this point, there were files called „secondary store“ and „index“, and „localstorage“ was also there.
• Eject then unplug kindle
• Turn on airplane mode
• Plug kindle into computer
• Copy the „index“ file from Winterbreak AND delete localstorage directory
• Eject then unplug kindle & reboot
• Open Kindle Store, turn off Airplane mode when promted. At last, bingo!

I just used Winterbreak to jailbreak my 2019 Kindle basic, and that seems to have gone well. But I am now trying to use the screensaver hack. I tried the one from the old screensaver hack thread, but it did not work. I tried it several times. Is there an updated hack that is compatible with the Winterbreak method? Thanks.

Unfortunately no. See this post.

It's not Winterbreak that's the problem but because newer firmwares >=5.16.3 switched to hard floats which is incompatible with the existing mods.

But there is a solution. You can downgrade (https://kindlemodding.gitbook.io/kin...indle-firmware) your Kindle 10 (KT4) back to 5.16.2.1.1 (https://files.cocaine.trade/firmware/kindle/KT4/) which should work with the non-HF stuff.

User beware of course so be careful.

Thanks!

Did you figure this out? I'm having it myself and unable to run the hotfix

Is it possible to downgrade the firmware of my PW5 now that I have Winterbreak installed? Would like to go back to a firmware version before the annoying Home/Library split home screen came in, if at all possible.

downgraded my 11th gen paperwhite just the other day with winterbreak

I was following this guide but didn't to run the hotfix (step 5) and went further in the guide before running into issues installing KoReader.

Is *** SQUASH JB *** expected to show up on every boot?

Everything went fine, I have a "Run Hoftix" on my kindle, but when I tried to start KUAL with ";log mrpi", it says on the bottom "Hush hush..", then for a short moment a 'box' logo appears, but closes immediatly. I cannot find any KUAL book in my libary.

I guess after connection there was an update as I am now on FW 5.14.3.2

I ran the Hotfix serveral times, and repeated the post jailbreak process several times (https://kindlemodding.org/jailbreaking/post-jailbreak/)

Don't now where to go from here...

I have exactly the same problem with my Colorsoft. A few weeks ago I was able to successfully complete the process for my Paperwhite 11th generation.

Thank you for this. I was able to downgrade as per kindlemodding instructions, but then apparently jailbreak was killed. Kual booklet was there but would not run. So, i read somewhere that in order to downgrade you have to be jailbroken. So while on 5.16.2.1.1 I started the jailbreak process again but right away it updated to 5.17.etc. Somehow I have to figure out how to immediately go into airplane mode, and connect to the computer to transfer all the jailbreak modules including the one to turn off ota, and execute Winterbreak without getting out of airplane mode. But enable ota because the downgrade process requires a spoof update. And then downgrade to 5.16.2.1. Is this pretty much the sequence or am I missing something? So, Jailbreak, downgrade, jailbreak again. I think that's it? Tomorrow I will try again.

Hey everyone,

I jailbreaked my Kindle Scribe recently, but I am not on the latest firmware update. Is there any way to safely update my firmware without screwing the jailbreak or my device up? I went to the KindleModding wiki, but it isn't quite clear enough on safely updating to a new firmware.

I have already attempted to update by restoring the OTA binaries and moving the 5.7.13 firmware update to the root, but the update failed.

What else am I meant to do?

If you're up for it I'd probably just try factory resetting the kindle and starting from the beginning. And if that didn't work I'd reset, manually update to 5.17.1.0.3, and then try...

Do not factory reset. There;s a good chance of ending up with a brick. When needs to be done is to install a firmware from Amazon. The only thing don't know is if you need the same firmware as is on the Kindle or the current firmware will do.

For what it may be worth, updating a PW4 (10th Gen) to 5.18.1 did not break WinterBreak. After the update, I re-installed the hotfix, KUAL and MRPI. KOReader worked with no additional work while USBNetLite needed a re-install. Without the re-install, I got network connection refused when connecting using Putty from my PC.
