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.
