Understanding Error 4008
Before diving into solutions, let's understand what this error generally means. Error 4008 indicates that the SP Flash Tool is unable to properly communicate with your device. This often boils down to issues with the connection between your computer and your phone, or problems with the files you're using for the flashing process.
Potential Causes of Error 4008
Several factors can contribute to this error. Let's examine the most common culprits:
