"""Make a Data seed that boots to SpringBoard instead of Setup: the preference changes github.com/dipa-studio/ios-sweet
|
|
(tools/sweet-root-tweaks.py) established on hardware, applied to a copy of an existing packed Data seed.
|
|
|
|
seed-data-skip-setup.py BASE.dbr OUTPUT.dbr [--no-auto-dim] [--build=BUILD]
|
|
|
|
BASE is a DBRDISK1 packed APFS container (drivers/DarwinBoot/Test/packed_ramdisk.py format). It is expanded to a raw image, attached
|
|
read-write on this Mac, the preference files below are merged into /private/var/mobile/Library/Preferences, and the result is packed
|
|
again. The volume UUID is unchanged. Nothing is written to Git or to the OS inputs; BASE is not modified.
|
|
com.apple.purplebuddy SetupDone, SetupFinishedAllSteps, SetupVersion 11, daemonizeNeedsToRun false (skips Setup)
|
|
com.apple.purplebuddy.notbackedup the mini-buddy flags false
|
|
com.apple.managedconfiguration.notbackedup LockdownActivationIndicatesCloudConfigurationAvailable false
|
|
com.apple.springboard BKNoWatchdogs, FBLaunchWatchdogExceptions{com.apple.purplebuddy: 100}, MCForceShowCloudConfigurationUI false
|
|
com.apple.migration LastSystemVersion (no data migration on every boot)
|
|
and the container directories under /private/var/containers that on a device live on the data volume.
|
|
--build names the OS build the seed boots (default 21H461): LastSystemVersion must equal it, or the system migrates its data on
|
|
the first boot (the progress bar under the Apple logo).
|
|
--no-auto-dim also sets com.apple.springboard SBDisableAutoDim, SBDontDimOrLockOnAC and SBDisableIdleSleep (as UniXNU-qemu's
|
|
build-os-root.py does): a board without input would otherwise turn its display off about 30 seconds after SpringBoard starts
|
|
and put the system to sleep.
