3uTools provides a detailed introduction to the “Advanced Settings” feature within “Smart Flash,” helping users better utilize the functionality and avoid flashing failures. Below is a detailed explanation of the feature:
3uTools Fixes Error 1110:
When the storage capacity of your iPhone/iPad reaches a certain threshold, it may cause the device to suddenly shut down and fail to restart. Attempting to flash the device while preserving data will result in an error message stating “Unable to restore device (-1110).” The “Fix Error 1110” solution addresses the issue of insufficient storage space while allowing users to retain their data during the restore process. (For devices stuck in an infinite white Apple logo loop due to insufficient storage space, the following method can also be applied directly).

3uTools Fix Battery Health:
This feature primarily recalibrates the battery health percentage for iPhone/iPad devices. Typically, a variance of around 1% between the battery health shown in your device settings and 3uTools is normal. If the discrepancy exceeds 5%, you can utilize 3uTools' fix battery health feature during flashing.

3uTools Secure erase Mode:
This feature can permanently erase all data from your iPhone/iPad, restoring the device to its factory blank state. It is designed for users who plan to sell their personal devices or securely destroy private data. Since this process formats every storage unit on the device's internal hard drive chip, the flashing speed will be significantly slow and may take several hours.

Unbind (Reading Factory Codes):

This feature allows one-click retrieval of original codes for device compoents during the flashing process, including: cover assembly code, proximity sensor code, ambient light sensor code, display assembly code, lidar module code and battery code.
If factory codes are successfully retrieved, as shown image:
