How did you install theos? And which SDK did you download?

I got Theos by following the rook tutorial and using putty on windows and I’m using the iphoneos9.3 sdk

Try these sdks: https://github.com/theos/sdks, download them and extract in the sdks folder. Then run: make clean package and see if that works.

after doing that i get 55 errors but i think it might have something to do with me being on ios 13, does that have something to do with it maybe?

It might be that the template I used in this guide is outdated for theos. You could try to make a menu instead with this template:

Hey, really nice tutorial, it gave me a nice motivation to start hacking on iOS devices too!

I've been trying to reverse engineer Head Soccer as my first proper project but I really did not understand how ASLR works on ARM64.

 

(lldb) image list "headsoccer"

[  0] 177C24B9-537F-3B7A-ACDF-74DDC1B4D35B 0x00000001022d8000 /private/var/containers/Bundle/Application/028CC5F9-515B-4E52-8380-ED4D992353B8/headsoccer.app/headsoccer

(lldb)

According to the guide I need to take the last 5 hex digits of the address 0x1022d8000, aka d8000 but I wonder if this is always the case or if the ASLR slide could include more or less digits (like 0x4000 or 0x100000).

Many thanks for publishing this guide!

Really good tutorial. Curious if there are any other good alternatives than mem scan+LLDB watch+IDA+repatch.
