Hello,

I successfully jailbreaked my Oasis2 (KOA2 9th gen).
I did it with my Mac (MacOS Sequoia) for people who would wonder if it work with a Mac.

After many many attempts with the normal method, I used the oneclick method and it worked directly. I should have started with this method which is so easier.
Thank you @Marek for your amazing work.

But I need some help: Now, Im stuck with a managed device.
The first post tells to type ;demo but when I do that, yes it asks confirmation (everything is in English btw), I click yes, It reboots, but comes back in the same managed situation after reboot.

EDIT: solved with a factory reset !
Now I've installed KUAL, python, librariansync, and the Kindle Collections plugin on my Calibre. Managing my collections has never been so easy and clean

guys

I found in /usr/bin/dump-stack that you can drop and empty file called DISABLE_CORE_DUMP in the main visible root (/mnt/us/) to stop Kindle from making core dumps (KPPMain, powerd, cmd, and possible others).

As far as I understood, this JB method requires this specific file in in the system root (/PRE_GM_DEBUGGING_FEATURES_ENABLED__REMOVE_AT_GMC) to be present in order for JB to work. This, in turn, makes Kindle a dev test device. Therefore, stack is dumped upon several actions, most of them are actually regular actions.

I tried it on Kindle Scribe, both on FW 5.16.2.0.1 and 5.16.21 (hardfloats, hf), and it worked both times. No more core dumps.

Only occasional things I still get is from Indexer, it dumps some archive and summary of what was indexed in /mnt/us/documents. But at least these are a few hundred KBs, and not 200-300 MB that core dumps were used to be. Most of the times it is when I exit KOReader that was launched in "no framework" mode.

This method is the least intrusive, and it doesn't seem to break anything big time. I can still browse Kindle store, read books, etc.

I went through a process on Kindle Scribe / 5.16.2. Had some fail attempts on the way, lastly using both hotfixes helped to get surviving JB outside demo.

From KUAL: KOReader works just fine! I also ran BinaryRenamer to lock OTA Updates.

The issue I have is: After a restart I see

Quote:

Something went wrong

An error occurred while downloading the update.

Try Again / Manage Wi-Fi

Is there any method to get rid of that? Right now I have to connect to Hotspot WiFi with login screen, and spam with my clicks on browser to get into "Home".

Also, as always... great work everyone!
