KOA3 Oasis with FW 5.12.2, what to do with it?

Hundebub · 02-16-2025, 04:46 AM

Hi!
I jailbroken my Kindle Oasis a few years ago via OpenSesame and done no update since then.
The Firmware is still on 5.12.2.
Are there any benefits to make a Factory Reset, do an update and make a new Jailbreak with Winterbreak?
I'm hoping for a better battery life, faster device,... when I'm updating to a newer Firmware?

Thank you for your advice!

You don't need to factory reset or re-do the jailbreak after updating the firmware, if you do the necessary preparations before updating the firmware.

If you already have jailbreak you need to install the newest version of "hotfix" package before installing the newer firmware. Then install newer firmware + do a couple more restarts (so no reset, but restart aka "reboot").
The you would check if ";log mrpi" command works or not. If iit works great you can proceed to reinstall KUAL and other staff you had and used on firmware 5.12.x. (if that stuff still works on new firmware, keeping in mind the whole switch to "armhf" ABI that happened with 5.16.3).

You are unlikely to get a faster device or better battery life by updating the firmware.

I have an Oasis 2 running 5.9.6 and an Oasis 3 running 5.12.4 and I wish that 5.9.6 would run on the Oasis 3, but it won't. I also have a Voyage running 5.8.11 and a PW3 running 5.9.6 and don't plan to update either one.

New firmware add new features, new misfeatures, fixes some bugs and has new bugs. For the most part I want to avoid the misfeatures and new bugs.
