Failed to inject frida-agent into launchd(pid 1) on iOS 14.5 jailbroken with Checkra1n 0.12.3

[QianNangong]

I'll get such error messages when connecting to frida-server

process with pid 1 either refused to load frida-agent, or terminated during injection

[as0ler]

I can confirm the bug. It ocurrs when attaching or spawning a new process.

Tested on Frida 14.2.17 with iPhone X and Checkra1n 0.12.3.

I can confirm this happens with 14.2.17 on 14.5 while trying to attach or spawn a(ny) process:
Unable to create connection: Error sending credentials: Error sending message: Broken pipe

Same here.
Problem seems to be valid for all frida on 14.2.X.
iOS is running frida available in Cydia's https://build.frida.re/.

Also it's valid for PID, identifier or app name.

[r3ggi]

[andrewpedia]

Still running into this on frida-tools v15.0.2, frida-server 15.0.8 and 15.0.13 (latest). I tested it on two different jb devices (iPhone SE iOS 14.6, iPhone 6s iOS 14.3). Note: Injection is working fine to many processes, but not cfprefsd or backboardd (Apple daemons). Attaching to some daemons does work , including launchd and com.apple.mobilesafari (from earlier post on this issue)

Thanks for reporting! This should now be fixed in Frida 15.1.0.

[Irisansan]

My Frida version is 15.1.3, but I still got the problem "Failed to attach: process with pid 7651 either refused to load frida-agent, or terminated during injection"😢😢

I'm getting this error on Frida 15.1.14 on Android device.

Why this issue is closed when it isn't really fixed?

[oleavr]

@bartlomiejduda This issue is about iOS. If you're running into issues on Android, please open a separate issue describing how it may be reproduced.

[bartlomiejduda]

@oleavr I have tested this once again after restarting my PC, restarting my phone and re-enabling USB debugging and it seems that there is no need for opening the new issue, because now everything works fine.
I'm using "frida-server-15.1.14-android-arm64" and I have Android 11.

Sorry for the trouble :)

frida-server 15.1.14 and frida-trace 15.1.14 still has problem when inject backboardd on iOS 14.7

I open a new issue #1983
