3. System files are missing, please upgrade again!

When the phone is upgrade through the web page, and finally the LCD prompts “System files are missing, please upgrade again!”

The purpose of this prompt is: the phone re-imports the just-upgraded version, after the second upgrade is completed. The phone can be restored to normal without the following black screen issues.

After this upgrade is complete, subsequent upgrades are the same as before, and only need to be performed once.

Note:
After the prompt "System files are missing, please upgrade again!" appears, press any key, the phone will enter a black screen state and the resource files are lost.
