Detailed explanation of the flash function of Aisi Assistant

Four flashing modes

1. Regular quick flash——Clear all data, flash selected firmware, and restore factory settings
2. Retain user data and flash the machine——Reinstall the system but keep personal data such as photos and address books
3. Anti-data recovery flashing——Deep clean, the data cannot be retrieved by recovery tools, use it before taking action
4. Keep the baseband and do not upgrade——Brushing the system does not move the baseband, and is locked/dedicated to special needs

Smart DFU rescue

When encountering serious problems such as white apples, black screens, freezes, etc., AISI's intelligent DFU rescue system can automatically identify abnormal conditions and guide it into DFU mode to re-flash and repair. It is much more friendly than manual DFU. For normal flashing, you can use recovery mode. DFU is only required in difficult cases.

iOS downgrade and signing mechanism

Many people want to return to the old version after updating to the new system. Whether it can be reduced depends on whether Apple is still "signing" that version. In the Aisi flashing interfacegreenThe firmware is the version that can still be flashed (still signed), and the red one has closed signature and cannot be flashed. The signing window usually closes 1-2 weeks after a new version is released, so be sure to sign in early.

Flash security

Flashing is essentially the same as system update and factory reset.It does not count as a jailbreak and does not affect the warranty.. Apple’s warranty policy is: within the warranty period, any non-man-made damage and non-jailbroken products will be repaired. However, a regular flash will clear the data, so be sure to back it up first.
