checkra1n app missing

[blackndoor]

iPhone X - 14.8

The checkra1n app is not there after a success jailbreak with checkra1n macOS app. I also tried to do as follow :

$ /Applications/checkra1n.app/Contents/MacOS/checkra1n -k ../../PongoOS/build/Pongo.bin

Then with pongoterm

sep auto
/send ../../PongoOS/build/checkra1n-kpf-pongo
modload
/send ../rdsk/rdsk.dmg // extracted from the checkra1n binary
ramdisk
xargs rootdev=md0
bootx

The iPhone boot correctly. The jailbreak seems working as cydia / newterm / ssh are working. But no checkra1n app.

Edit:

I just checked the loader.app and the file size is 0:

iPhoneX:/ root# ls -la /var/binpack/Applications/loader.app/
total 0
drwxr-xr-x 3 root wheel 96 Oct  2  2021 ./
drwxr-xr-x 3 root wheel 96 Oct  2  2021 ../
-rwxr-xr-x 1 root wheel  0 Nov 25 12:17 loader*

This means the loader.dmg was not actually mounted. This is just a 0-sized file that would normally be hidden under the real mount (I don't quite remember why we create it). Is /binpack even mounted correctly?

[blackndoor]

yes ls /binpack was mounted. I finaly get it work.

I used checkra1n to jailbreak, got the checkra1n.dmg from the device and got the loader.dmg from it. I extracted the loader.dmg in /var/binpack/Applicationand the checkra1n app was working. I removed the jailbreak using the app and then jailbreak again using checkra1n.

I lost all my tweaks but at least now it works. I guess I have to figure out how you push the checkra1n.dmg to the device and used it.
