[Xperia SP Q&A, Help & Troubleshooting] Braxley1:
After trying to flash the phone unfortunately the issue still persists. The LED is a solid red when charging and blinking red when not charging. No power. No vibration when holding power and either volume button.

When i connect the phone through USB it is detected and drivers are installed .

I retried flashing a second time, however still no different. At the end of flashing flashtool prompted this message "For flashtool, Unknown Sources and Debugging must be checked in phone settings"

Have i done something wrong with how i've went about this?

Here's the log, please let me know if you can help.
