The 4.2rev04 update was a batch IOS update released shortly before 4.3, much like 3.4rev02. It provided various enhancements to IOSes in addition to blocking homebrew. IOSP, ES, and SDI were updated to versions built on March 1, 2010.
Changes
- IOS9 now has a build tag
- This version of IOS9 was released in Japan in 4.3
- IOS21 still has this patch
- Several IOSes have been replaced with copies of other IOSes
- IOS13, IOS14, and IOS15 have been replaced with copies of IOS17
- These copies only differ in the version number stored in NCD
- IOS15 no longer has the NAND Boot Program
- IOS31, IOS33, IOS34, and IOS35 have been replaced with copies of IOS36
- Some of these IOSes were already identical, but the version number was updated to match IOS36
- In Korea, IOS41, IOS43, and IOS45 have been replaced with copies of IOS46
- Like the corresponding worldwide versions, some of these branches were already identical, but the version number was changed to match IOS46.
- IOS37 and IOS53 have been replaced with copies of IOS55
- IOS13, IOS14, and IOS15 have been replaced with copies of IOS17
- Added IOS80 to prepare for 4.3.
- ES now creates /wfs on startup, although it is not used.
- Homebrew fixes
- Fixed HackMii Installer Userland+Syscall IOS exploit in all IOSes (including IOS58, which was previously not on NUS)
- ES_AddTitleFinish now checks signatures
- In Japan, IOS9, IOS57, and IOS61 were not updated, instead being updated in 4.3.
- The function used to verify pointers in the kernel seems to have been updated to take the process ID as a parameter instead of determining it automatically from the current thread. The function that required this change is not known.
- A bug was fixed in SDI where the read and write IOCTLs used an int for the register index as opposed to a short. This allowed any memory accessible by SDI to be leaked to or rewritten by the Broadway, and may have been used by the HackMii Installer.
- Updated EULA in E and K regions.
