[Q] HTC One M7 Dual SIM (M7DCWG) S-ON Tampered. Can't install Stock ROM

Hi All,

I have a problem that I want to back to Stock ROM using this RUU. RUU_M7_UL_JB_50_hTC_Asia_WWE_1.29.707.3_R_Radio_4A .14.3250.13_10.33.1150.01_release_311678_signed.ex e

My device status is TAMPERED and RELOCKED with S-ON.

This error is I've got when trying RUU : ERROR [132]: SIGNARURE ERROR. The ROM Update Utility cannot update your Android phone. Please get the correct ROM Update Utility and try again.

Is there any solution other than S-OFF-ing first ?

And this is my device's fastboot getvar all
