Hello! The "ERROR S_TIMEOUT (1042)" message usually appears when there is a communication error between the computer and the device during the flashing process. Here are some steps you can try to fix the issue:
1. Make sure that the USB cable you are using is of good quality and properly working.
2. Try using a different USB port on your computer.
3. Check if the Huawei USB drivers are properly installed on your computer. You can download and install them from the Huawei website.
4. Try using a different firmware file and a different flashing tool.
5. Make sure that the battery of your device is charged at least 50% before flashing.
6. Disable any antivirus or firewall software on your computer, as they may interfere with the flashing process.
If none of the above steps work, you can try contacting Huawei customer support or seeking help from a professional technician.
