Without getting too critical of your code (congrats BTW), never use strcpy instead use strlcpy.

strcpy will happily allow you to create buffer overflows (a common challenge with C) which will cause your application to crash.

You’ll find more details here.

Good luck!

The handful of us have moved onto Crystal Lang. It’s a statically type checked and compiled dialect of Ruby. Crystal is fun to write code, but the compiler is slower (compared to go-lang/rust)… because… well it’s a ruby dialect (with DSL’s)… and the 3rd party libraries are limited.

Thank you for finding that.

I got lucky, I bought a quest around July/August and needed to do the mandatory/initial OS install.

I ended up with v78 (August 3, 2025) release.

I didn’t realize there was a WiP announced in July 2025.

… makes the latest headset with a rather recent update (but NOT the very last ones, so be cautious!) rootable.

Any ideas which version(s) are susceptible? I couldn’t find it mentioned.

Actually, those steps are the ones necessary to recover from a hard brick (re: the device is unusable because you did something you shouldn’t have as root).

The actual process to root the device is simply running a few adb commands (so a prereq is having Developer Mode enabled).

Once you have ran the exploit, your root escalation is temporary until the device is rebooted or you take additional steps to persists your root privileges (thus, potentially leading you towards a hard brick).
