S-BOS3 Introduction and Supported Model
- Introduction
- Used for writing ROM data for USB-C CD chips (CD3215 and CD3217).
- S-BOS3 come pre-loaded with original factory ROM data for USB-C CD chips found in devices manufactured between 2016 and 2023.
- The Type-C circuitry in MacBooks utilizes 5V-to-20V voltage boost process; corruption of the USB-C ROM data will result in the motherboard receiving only 5V of power.
- When MacBook motherboard receives only 5V of power—characterized by the current repeatedly cycling on and off—it indicates that the USB-C ROM data is corrupted.
- Use the S-BOS3 tool to write the corresponding ROM data for the specific model, thereby restoring the motherboard's power supply to its normal 20V boosted state.
- S-BOS3 contains pre-loaded CD ROM data covering iPad, iPhone, and MacBook models.
- Supported Models
- Compatible with MacBook, iPad, and iPhone models featuring Type-C interface, manufactured between 2016 and 2023.
- MacBook models manufactured between 2016 and 2018 utilize the CD3215 USB-C chip.
- MacBook models manufactured between 2019 and 2023 utilize the CD3217 USB-C chip.
