PatchMii is a software tool designed to make the process of patching IOS more automated and convenient. It is equipped with a framework for working with IOS, as well as a specific piece of code for downloading and patching IOS37. The software patches the IOS and installs the updated version in the IOS254 slot (IOS5 on older versions).
The two patches made by PatchMii include the signature patch and the DI patch. The signature patch modifies the IOS signature checking function to return 0 instead of 7 when the hash comparison fails. This is done by changing the instruction "mov r0, #0x7" to "mov r0, #0x0". The code checks for either 0x23a2 (found in vulnerable IOSes) or 0x4b0b (found in fixed IOSes).
The DI patch, also known as the drive chip patch, changes the length of the DVDLowUnencryptedRead 00000000 region to allow unencrypted discs to be read. The length is changed from 00014000 to FFFFFFFF. The software matches the entire region whitelist but only modifies the first region.
By using PatchMii, the process of downloading and patching IOS becomes much more efficient and streamlined, saving users time and effort.
PatchMii-core will do the following things:
- Download the ticket and TMD for IOS37 from the Nintendo Update Server.
- Decode the title key using the built-in key-management functions of IOS, eliminating the need for a common key.
- Download all encrypted contents from NUS, verified against the hashes in the TMD.
- Decrypt each content, display versioning tags inside the binaries.
- Patch out the signature check, accommodating all versions of IOS.
- Re-encrypt the contents, recompute the hashes if necessary, and modify the TMD.
- Change the title ID in the TMD and ticket to IOS5.
- Fakesign the TMD and ticket.
- Install the patched IOS37 as IOS5.
This configuration ensures a seamless process of downloading, patching, and installing IOS, making it easier and more efficient for users.
The output of this process looks like this:
