SpringBreak

Note

WinterBreak3, PenguinsBreak, Etc.

SpringBreak is a jailbreak for KT5, PW5(SE) on 5.19.2+, KT4/PW4 5.18.1.1.1.

How It Works

1. Load modified store cache with upwards of 5-10 thousand nested folders to prevent cache deletion upon eject.
2. Schedule SET.SCFG document with ToDo (Kindle API) in order to set winmgr.vibrancyMode.pref.path to custom SH
3. Start com.lab126.fts via the AppMgr Kindle API seeing as it can communicate to com.lab126.winmgr, pointing to a custom URL. This, in turn, calls vibrancyMode, triggering the SH mandated in the ToDo document. (In this case, KindleModding's online jb.sh.)

Build

Because MacOS scares me:

• Windows: GOOS=windows GOARCH=amd64 go build -trimpath -o springbreak.exe installer.go
• Darwin (Build from Source):
  • GOOS=darwin GOARCH=arm64 go build -trimpath -o springbreak-darwin-arm64 installer.go
  • GOOS=darwin GOARCH=amd64 go build -trimpath -o springbreak-darwin-amd64 installer.go
  • lipo -create -output springbreak-darwin springbreak-darwin-arm64 springbreak-darwin-amd64
  • codesign --force --sign - ./springbreak-darwin (Or, Developer Cert: Credit Fynn)
• Linux: GOOS=linux GOARCH=amd64 go build -trimpath -o springbreak-linux installer.go
