Tools AdBreak - experimental JB for ad-supported devices (5.18.1-5.18.5) - Page 11

spedinfargo · 11-23-2025, 02:15 AM

Just a quick note that I received my refurb 2022 Gen 1 Scribe in the mail today and I followed Shadow's instructions and can confirm that along with Joe I was able to jailbreak my scribe. I had to create a new phone number in Google Voice to create my French account, but after that it was pretty straightforward.

This is the first time I've ever jailbroken a Kindle, so I'm still pretty fuzzy on how the scriptlets, KUAL, MRPI, etc. etc. all work together. I did manage to get KOReader installed, though, so I'm pretty happy about that.

Thanks for the great instructions and the troubleshooting help on this forum...

They don't show up under the "Show All offers" section, but it does replace the lock screen with a lady and a telescope. Once you get that far, the system .assets folder shows up, and you can perform the remaining steps.

There are several tools because each does a different task. The jailbreak itself is only the first step and doesn't do a whole lot on its own.

Jailbreak - Exploits some security flaw to allow the Kindle to run 3rd party code.
Hotfix - Shims itself into the Kindle OS so that keys to run that 3rd party code stay in place, newer ones also add features like scriptlet support to run user scripts right from the Library.
MRPI - Uses the Kindle search bar to get the debug logging system to launch the custom package installer.
KUAL - A custom launcher that can run other programs. Scriptlets let you skip going through this to run programs.
BinaryRenamer (or the older RenameOTAbin) - Tool to block downloading and installing firmware updates
KOReader - A 3rd party reading program that runs on top of the regular Kindle OS.

Trying to jailbreak my Paperwhite Gen 11 using ad break. My device is on 5.18.5.0.1. I have enabled ads and gone through all the steps. When I click on an ad in View All Ads I get a version number, click on close and get a message that I'm in airplane mode do I want to turn it off. Any ideas as to what I might have missed?

I don't know for sure, but I will say that when I did the jailbreak on my 11th gen PW about a month ago, I did have a problem with the replace.bat not working correctly the first time I ran it. Here is what I wrote back then:

Everything acted as expected with one exception. I'm not entirely sure that replace.bat worked when I double clicked on it. After it 'ran' I went into some of the folders and the details.html files did not match the attributes of the adbreak.html. So I opened a command prompt as admin and went to the location and ran replace.bat again. That time it definitely worked. (file sizes matched, etc.) I'm on Win11 fwiw.

So...check to see if the details.html files match the size/etc. of the adbreak.html file. If not, then replace.bat may not have worked for you?

fwiw, I was on Win 11 and my PW was on 5.18.3.

Thank you for responding. I tried this and it didn't work. I noticed as the bat file ran a message flashed very quickly said that the process could not run or something to that effect.

So, I'm going to ask this a different way...if you look into some of the subfolders in the .assets folder, does the details.html file have the same date time and size as the adbreak.html file?

during the process, you copy the assets folder from your kindle to your pc and then you run the replace.bat. what replace.bat does is for every subfolder in .assets, it copies adbreak.html into that subfolder as details.html (which replaces the original details.html file in those subfolders). So the result should be that all of those details.html files have the same date time and size as adbreak.html had.

if details.html does not match adbreak.html, then replace.bat did not work. I had to open a command prompt as administrator and then rerun replace.bat

Marek has a script for getting the OTA update URLs, assuming you're able to collect the Amazon token from /var/local/token/

So far I've only been able to collect for my own device.

TLDR: Currently no but probably possible, avoid updating.

You can find 5.18.5.0.1 here https://ftvdb.com

Kindle Scribe (1st Generation) 2022 5.18.3

Ads enabled but only one generic (telescope) ad. Kindle reports 0 ads

Hi, In my .assets folder I have one subfolder named with a 13 digit number that contains all the files:

banner.gif
details.html
screensvr.png
screensvr_active.png
snippet.json
thumb.gif

I've been putting adbreak files back in that subfolder after running replace.

When I click the generic ad I get a series of boxes showing numbers (lbc base ad etc)

Then Bang which seems to do nothing.

Running Update_hotfix_universal gave me 'failed update' so I've been going back to the start with a factory reset trying to see where I went wrong.

Should I be putting the files outside the subfolder instead?

Do I need to get more ads first? I gave it hours but no more appeared.

Is it even possible on a scribe on 5.18.3

Greyriver · 01-02-2026, 09:18 AM

Btw I have the kindle nearly full of fake files to prevent an update, but with 20mb free it somehow manages to download a 360mb+ update anyway and I have to quickly delete it.

I don't get how that works at all

Greyriver · 01-02-2026, 10:29 AM

WORKS NOW!

I was doing it all wrong putting the files into the subfolder.

Doing the rest of the steps now

After many false starts and enabling/disabling adverts on amazon I must have triggered some security feature because I could no longer enable ads on the device. Amazon would let me set it but the kindle never created the folder.

I solved this by connecting the kindle via another IP (hotspot on my phone) and then it got the enable ads message.
