The baseband that will be used for custom IPSW restores in Legacy iOS Kit will vary depending on the device and version, but it will be the latest baseband for most cases.

  • A4 and older devices:
    • Baseband update is disabled for all restores with some exceptions below
    • If the device is restored to the latest version with the jailbreak option disabled, latest baseband will be used
    • iPhone 3G and 3GS: If the jailbreak option is disabled for iOS 4.1, the 4.1 baseband will attempt to flash. However, this will always fail (unless the baseband is in a lower version), and the device will be kicked out of recovery mode after the restore
  • iPad 2 and 3 cellular:
    • Baseband update is disabled for all restores, except when updating to latest iOS 9.3.5/6
  • iPhone 4S, 5, 5C, iPad 4, mini 1:
    • iOS 9.3.6/10.3.4 baseband will be used for all restores, except when the disable-bbupdate or dead-bb flag is enabled. For more details regarding flags, go to Troubleshooting#script-argumentsflags
    • Warning: The "disable-bbupdate" flag does not always work in preserving baseband functionality. There is a chance of non-working baseband after the restore, so this option is considered as unreliable. Please do not enable this flag and use the latest baseband. Baseband version is useless on these devices anyway.
  • A7 devices:
    • (except iPad4,6) iOS 10.3.3 SEP and baseband will be used for 10.x restores
    • Latest iOS 12.x SEP and baseband will be used for all other restores
  • Newer A8/A9/A10 devices:
    • Latest iOS SEP and baseband will be used for all restores
