v1.0.0

What's new

• First stable release 🎉
• Completely reimplemented the App patcher to support split APKs and XAPK files.
• [AppPatcher] Added normal install method (non-root). You no longer need to save the file and manually install it.
• [AppPatcher] Removed problematic mounting scripts in direct install mode.
  • ⚠️ The files used for mounting will still remain on your system unless you run the direct install process again, which will remove the legacy files for you, or you can delete them manually in /data/adb/umapatcher
• Added support for other versions of the game (KR, TW GP, TW MC)
  • ⚠️ As the time of making this release, Hachimi does not work correctly on any of these versions yet. Check the compatibility table on the Getting started page for more info.
• Added options to export and import signing keys.
• Added option to force redownload Hachimi.
• Legacy repo files from v1.0.0-beta4 and older will be removed on launch. First launch might take a while if you upgraded from one of these older versions.
• Properly enabled optimizations for release build.

v1.0.0-beta4

What's new

• [App patcher] Implemented shared library addition for APKs that has been stripped of their lib folder.
  • This fixes an issue on Android 14 where the lib folder is missing from the installed APK file, resulting in a broken patched APK. This is only implemented for "Get APK file from installed app" and will not work with an APK file dumped by another app.
• [App patcher] Replaced zipalign-java with ARSCLib for APK aligning.
  • This fixes an edge case where the APK would get aligned incorrectly, leading to a "corrupted" file.
• Added progress indicator for file copying/saving.
• Added indeterminate progress indicator.
• File copying optimizations.

Bug fixes

• [App patcher] Only add patched library for architectures that are present in the APK file.
• [Patching screen] Correctly handle user cancellations when saving file to external storage.

Incompatibility notice

The following devices has been deemed to be incompatible with Carrotless/UmaPatcher:
