Update:
Seems like KT1 and PW1 jailbreak kits won't make it in time for the thread lanuch. Thanks to SKK we managed to test them on multiple different iterations of the image, and it seems like there is something different from newer devices other than the location of their GOT and W/E memory pages. I'm planning to further test these before I start with versions between 5.8.x - 5.10.x.
As for 5.11.1-5.13.3, we only need one version tested that's already queued up for later (today hopefully), so the new thread is imminent.
