[Q] root phone error

Hello,

Im trying to root my Alps E1911_v77_gq2000_9p017 phone with SRS root software, my phone is on the list of supported phones but it will not work

---= SRS One-Click-Root v4.3 =---

16:07:16 - Starting ADB Server..
16:07:21 - ADB Device: NOT FOUND

ERROR: Make sure your device is connected in Android Debug mode, and the drivers are installed. then try again.

my phone is already in android debug mode so I don't know what else to do?

thanks
