I just would like to say big thank you to all involved in making this JB! I really appreciate time and effort and easy to use guide. I was able to root KT4 on 5.17.1 and downgrade to 5.13.5 and root it again :-)
Big KUDOS!

Hello guys. I followed the guide and was successful but now kual doesn't open anymore. my firmware went from 5.16 to 5.17.1.0.4 even though I disabled updates. It seems I did something wrong along the way. Can this be fixed?

Run the hotfix “book” again

When you installed RenameOTABin, did you open it in KUAL and tap Rename? It should have rebooted after you did so. If you didn't then the OTA wasn't actually disabled.

Thanks
I thought I did but apparently not. Using the hotfix book didn't do anything, then I took a risk and did a factory reset and it worked. I cracked it again and this time I was successful. My problem now is that koreader won't open. It blinks but then returns to the main screen. I installed several versions, the latest I tried was from this page, all three kindle downloads
https://build.koreader.rocks/downloa...02-22/?C=M&O=D
Any fix for this?

Thesnake · 02-24-2025, 08:28 PM

lol fixed it by installing hf version of koreader. Everything is good now,

b0dhimind · 02-24-2025, 10:28 PM

Thanks, yeah needed to use Marek's KHF version. Likely due to using Marek's KUAL in the first place.

Not quite right. You needed to use Marek's or other kindlehf version since Kindle firmware 5.16.3 or higher uses hardware floating point (the hf in the filename).

Hi there!
Could you please tell me if it is a way, or if it will be a way, to jailbreak a new KindleColorsoft without an Amazon Account?
I brought mine second hand and it looks like it is active on another Amazon account and not blacklisted.
Thanks a lot!

I went back through the sign-in and registration process.

KFT was still lingering around in the Settings menu. I understand it's just an artifact of the jailbreak process, but I'm looking for an "out of box" configuration on the device, so I decided to Factory Reset from Settings.

Went back through the sign-in and registration process and KFT is still in the Settings menu

Normally in order to completely remove the jailbreak you have to reinstall an official firmware update twice, without running the hotfix in between. Your Kindle won't let you install the .bin file for the firmware that you already have installed, but you can try this to trigger the install:

When you copy the firmware files DON'T eject Kindle from your computer, instead press and hold the power button for 15+ seconds to force a reboot. That should then trigger a firmware install.

I'm not sure why you would want to keep someone else's account on your Kindle, but if that account is already logged in, then WinterBreak should work. The exploit needs the Kindle to be registered because of the way it works (the store cache will only load on a registered Kindle), but the actual account doesn't matter.

Drybonz · 02-25-2025, 11:41 PM

I applied the jailbreak tonight and it seemed to go without any problems. Thanks for this.

I originally wanted to downgrade my Scribe firmware to the previous one, before they added the un-hideable icon to the reading area. I noticed that downgrading will wipe my device. Before I get into anything like that, has anyone created a jailbreak "fix" that will hide that icon on the current Scribe firmware? Thanks for the help.

My Kindle does not have an account logged in. The amazon support told me the kindle is active.

Ok, I’m not too familiar with the issue you’re facing, as I’m not aware of any Apple-like “Activation Lock” feature on the Kindle, so it should not really matter whether it’s active on another account or not.

Can you boot the kindle normally to the Home Screen? If so, doing a factory reset should wipe out any lingering account information and trigger the registration process, enabling you to enter your own account information. If the Kindle won’t go past the registration page, or won’t let you enter your own account details, then you won’t be able to jailbreak it.

Shakeupyourbones · 02-28-2025, 02:06 PM

I’m not having luck getting past the “unexpected error” message when you go into the amazon store. I’ve followed instructions and troubleshooting steps to the letter and also followed along with multiple videos on youtube. I’m on a Oasis 10th gen running 5.17.1.0.3. I’m also using a Mac to load everything if that helps. Any help would be greatly appreciated!
