Note:
1. The U disk(Gold USB flash) only for Mac system.
2. Now gold USB flash doesn't come with software, because the software has expired, there is only a backup software, and it can't be used for devices that have been flashed and whose system version is higher than 6.0.

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.
2. If you enter the DFU mode to restore the machine with the T2 system, the T203 will not be able to bypass the activation lock normally.
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.

Functions:
1. T203 is mainly used to unlock the ID activation lock that appears on the activation interface of the Macbook with T2 chip.
2. When T203 is used to remove the ID activation lock, it can also be used to determine whether the T2 ROM data is damaged and the failure to boot is caused.
