RELOCKED bootloader ! Getting RUU Error 155 topic

I have T mobile HTC ONE.

I tried to go back to stock T Mobile version. But getting RUU.exe error 155.

Tried RUU :
RUU_M7_UL_JB_50_TMOUS_1.27.531.11_Radio_4A.17.3250 .20_10.40.1150.04_release_324846_signed
RUU_M7_UL_JB43_SENSE50_MR_TMOUS_3.24.531.3_Radio_4 A.21.3263.03_10.38m.1157.04_release_336982_signed_ 2(2)


My HTC ONE is RELOCKED bootloader.
