G935P Network Unlocked Can't Access Hidden Menu


I unlocked a G935P but I cannot access the IOHIDDEN menu. I am on binary 5. I have tried to downgrade with no success. ADB shows no command found when I try to use the commands to enter.

I also tried to jsut flash it over to a T-mobile rom but I can only find binary 4 for it.

1. Connect to WiFi
2. Setting/ active this phone
3. Wait till it say fail
4. Look at the top right connect for the "three dots icon"
5. click QPST, then select IO USB debug ( dont remember for sure the name - but you will find out.)

I need to have 10 post for links, since there's no link here I don't understand but... anyways, remove the spaces on

"android . provider . Telephony . SECRET_CODE"
"android_secret_code : / / 27663368378"

flash stock
root with engroot

adb shell
am broadcast -a android . provider . Telephony . SECRET_CODE -d android_secret_code : / / 27663368378

​There you go, hidden menu. Hope it helps.
