Alright, this edible's gonna be kicking in soon. Let's write this real
quick.

Untethering 10.3.4 currently, with publicly available tools, would go
roughly like this:
 - modify sockH3lix (haven't heard that name in years lol) to run the
   kexp as soon as the bin is launched [note 1]
 - sign it, install it on a 10.3.4 device
 - use spv.sh/work/untether_bugs / the p0laris untether bugs to bypass
   launchd's platform bin requirement and run the binary using the mount
   trick or dhcpd
 - sync, reboot, have fun
 - remember to resign every 7 days, or get a $99/yr dev cert and sign
   for a full year

note 1: i have code on some drive, around here somewhere, to do exactly
        this. remind me tomorrow to look for it lol :)

also, i actually did this in the past
(https://www.youtube.com/watch?v=gNPzmvApm3g,
https://www.youtube.com/watch?v=jdQmg5qFKus) it just wasn't at all code that
i'd release as a proper untethered jailbreak, due to the signing
inconveniences and general jankery

also sidenote those 2 demo's iirc used a different platform bypass that
i'm not sure i ever publicized, so i won't name it. it would be very
easy to find, people have lol

sidenote 3 it was brctl, idfc anymore lol -- no point in keeping it
secret because these bugs are essentially dead anyway with 15.x+

cya! <3
