Have You desoldered/disconnected TP? Please check.

[john-ammu]

yes i removed the test point after assembling did the kill switch

[Octopus box]

If device is always detects as "qualcomm hs-usb", this means that TP is still circuited or phone's boots are damaged, or device has HW issue. "Reset Kill Switch" operation doesn't work with phone's boots, so they can't be damaged after this operation. Please disassemble the phone and check carefully again, maybe TP is still circuited or, maybe, You have circuited something on phone's PCB when soldered TP.

Please disassemble the phone and check carefully again, maybe TP is still circuited or, maybe, You have circuited something on phone's PCB when soldered TP.

Also, please use the latest Software version
