I tried and got this line: my game Name Garina Free fire Error : unable to find module 'libil2cpp.so' Use memu player 8.1 emulator In Windows

vfsfitvnm commented 11 months ago

if you are using an emulator, you may need to use --realm=emulated frida flag

ekologic commented 11 months ago

I've been also facing the issue on emulator when using the realm flag, tried in Memu and LdPlayer

 frida -U -f com.some.game -l ./output/hook.js --realm=emulated

Currently trying frida-gadget, on a real device it works, but in emulator it is freezing for some reason on init, some issues loading the injected library (sorry for offtop)

EDIT: after some digging in the logs of the emulator I get this and the similar with frida-gadget: enter native_bridge3_loadLibraryExt /data/local/tmp/re.frida.server/frida-agent-arm.so, 1, 0x3 I mean after this gets stuck on this line

I believe it has something to do with libc+houdini according to the tombstone logs

I assume a frida issue
vfsfitvnm commented 11 months ago

Yep, it looks like it is. I've had success using frida on the official android emulator image (ref, ARM only), but I guess it won't work if your game can detect emulators and you are not prepared for that
