I haven't.

The truth is my current firmware was flashed by a friend.

I supposed upgrading firmware is not as difficult as flashing a totally new firmware right?
I last updated a router firmware was back in 2013.

Yup..much easier than flashing new firmware.

1. Download latest firmware from XWRT-Vortex website
2. Extract the firmware to your harddrive
3. Login into your router from 192.168.1.1
4. Go to: Administration > Firmware Upgrade > Choose File > Locate the .trx file > Click Upload
Very Important:DO NOT update your firmware through Wi-Fi. If the upload stream is corrupted, you may brick your router. When uploading firmware, always use ethernet cable
