su for remix not working and its diag mode (read cdma/qpst)

I know there is not much support for the remix, though it's essentially a mini 2...too. I have it s-off and unlocked. I have twrp recovery on it. The all in one utility on one of these threads didn't work well for twrp so I flashed it via fast boot. I've tried running the utility for gaining root but nothing shows up in twrp under sdcard. I have pushed it to another folder, I find it and flash the zip file but even though it says it finished fine, when I reboot nothing is there. Weak sauce2 works fine, but that's just temp. I want permanent root.



That said anyone know how to enable serial/modem communication to cdma/qpst on the remix? I've been trying forever. Im trying to backup the prl.
