Download the TWRP 188.8.131.52 img from the Teamwin website, rename the file to something easy like "twrp2702.img" and place that file into your adb/fastboot folder.
Boot the phone into the bootloader (make sure you first disable Fast Boot in Settings > Power)
Fast Boot is not to be confused with fastboot LOL
The former is a HTC feature to speed up boot time, the latter a protocol to communicate between PC and phone.
Open a command prompt from your fastboot/adb folder.
Hopefully you also have the fastboot drivers installed, try it with
If you get the alpha numeric string, you're good to go
fastboot flash recovery twrp2702.img
Once that is done
Uninstall Weaksauce if not done already.
Then download the flashable SuperSU zip and flash it in TWRP to gain permanent root.
