CC BY-NC-ND 4.0. + 悪用厳禁. But, the exception to this definition is that changes to the code signature portion of the app's executable binary (Payload/daibutsu.app/daibutsu) do not constitute "modified" as defined by Creative Commons. Only modifications to the code signature of the app's executable binary (Payload/daibutsu.app/daibutsu) are defined as modifications that satisfy the "NoDerivatives" constraint. This means that a sideloading service can replace the signature of the app's executable binary (Payload/daibutsu.app/daibutsu) with its own valid signature and distribute it.

Note: Any modification of the app's executable binary (Payload/daibutsu.app/daibutsu) other than the code signing part defined by mach-o is not allowed under any circumstances.

Prohibition of rehosting ipa, prohibition of modification of ipa, Prohibition of tampering with ipa. This ipa can only be distributed by dora2ios/sakuRdev. (v1.0b2 or lower)


How to use?

1, Download and sign ipa.

Download ipa and sign with iOS App Signer v1.13.


2, Open the app.

Open the daibutsu app.

If you used an expired certificate and sideloaded it, you should be able to boot by reverting to the date before it expired.


3, Press the jailbreak (脱獄) button.

This will start the jailbreaking process.

That Jailbreaking process has three steps, after that, cydia and untether will start installing. Don't touch the device. And, I recommend doing this while charging.

And when everything is done, you will see a popup like the one below.

Device will reboot and boot with jailbreak-state.

This is already untethered jailbreak. Enjoy this jailbreak :)
