The iOS version argument should be the iOS version of your device. It is required when starting from DFU mode.

1: download your ipsw and put it on ipsw/ directory (you can download of ipsw.me. please only ios 14.* also please download exactly your ipsw for your device) (your ios version that you want to dualboot with also is recommended ios 14.3 because you can jailbreak with taurine)

2: execute ./dualboot --dualboot 14.3 (the version of your ipsw downloaded which is the version that you want to dualboot )

3: ./dualboot --boot

just in case kenelpanic

in case that your iphone not boot on the second ios try to do this: you will have to record a video of iphone's screen because you have to note the name of the preboot directory when that is booting.

IMG_0769.MOV

so you will see that is booting however that will reboot because the preboot directory is not created so we have to create it. you have to record a video which look like above. after you have take a photo or to note the name of the directory

like this so note the name /private/preboot/thisName/usr/standalone/firmware now boot ./sshrd.sh or any ssh ramdisk after execute mount_filesystem, execute mount_apfs /dev/disk0s1s10 /mnt4/ after that execute mkdir "thisName" | mkdir "thisName"/usr | cp -av /mnt6/"theonlydirectorythatexist"/usr mnt4/"thisName"/ reboot and your iphone should boot without error

how to jailbreak

---

to jailbreak your device: ./dualboot.sh --jailbreak 15.7 (or your version) after install trollstore with https://github.com/verygenericname/SSHRD_Script, after install 2 ipa in the dualboot repository 3 taurine and pogo also filza if you want, after open taurine and jailbreak it when that reboot, boot again to the second ios, open pongo which was installed by trollstore and click do all (never click install that can break the jailbreak so only you will use pongo to press do all) after that you can use sileo to install package and install libhooker to inyect tweaks (if you reboot your device, the tweaks will be disable so you have to reinstall libhooker opening sileo and press reinstall ) or you can use pogo install to install the jailbreak but never both together.

---

for any error you could create issues

this is a video booting my second ios:

dualboot_compressed.mp4

test it on iphone 6s on ios 15.7 using macos big sur

in the case that you dont trust about binary, you can download of palera1n binary both are the same binary and compile https://github.com/Ralph0045/dtree_patcher.git and copy to binary Darwin directory this is the only binary that palera1n does not have it

you can not do it on linux because dtree_patcher does not work and asr command not exist, if you have any solution, share please.

thanks

THANKS PALERA1N, https://dualbootfun.github.io/, MatthewPierson, Ralph0045, people who help me test on discord like @something, @samm and others and all people who created the boot patcher tool. thanks
