T203 Precautions and Usage:
1. After the iCloud activation lock or PIN code lock appears on the 2018-2020 MacBook, do not enter the DFU mode and use the "Apple Configurator" software to restore the T2 system.

3. For machines that cannot bypass the activation lock normally, only the T2 chip and T2 ROM chip can be replaced by a hard solution.
4. According to the new operation method, read the original ROM data, then change the new serial number, write the data back to the ROM chip, and finally use the T203 software to bypass the activation lock.
5. Remember: After changing the serial number and writing back the ROM data, you must not enter the DFU mode to use the "Apple Configurator" software to restore the T2 system.
6. Bridge OS systems below 6.0 can be read successfully, but the ones that have been swiped can't, and those that have been swiped can only be hard-solved, that is, change the kit.
