ServiceMode Access - Samsung Galaxy S8 Questions and Answers

Has anyone else tried messing around with service mode on stock firmware?
I have a g950u from T-Mobile and I accessed it by entering (+30012012732+ into the calculator then entering *#197328640#
other codes work but I can't get to a menu with them

I9505 unlocking

I've attempted to sim unlock my galaxy s4, however using the *#0011# method it will not enter service mode after the "key input 1" step. Is there any reason why I cannot access the main menu of the service mode, or is there any alternative? Thanks.

[Q] Accessing Diagnostic Menu in 4.4.2

I've been trying to access the diagnostic menu (sometimes called service mode) on my S4 which has an unknown imei so I can try and rebuild it but all I ever get is a blank screen. I've tried every code I can find but the blank screen is as far as I get.
Am I missing something obvious?

[Q] Can't access RNDIS + DM + MODEM. Codes don't work.

I am an owner of an unlocked I337M with Koodo. I have a custom rom, GPE 4.4.4 which is also rooted. In order to use Wind or Mobilicity (AWS , 1700), I must enable this function through various guides I've followed; however, I can not access this "Hidden Menu" for the USB Settings.
The only code which works is *#06# which shows my IME.
I have also turned ON the "Hidden Menu" script within the system using FX browser.
*#7284# - *#0808# - *#9090# and every other ones I have entered do not work. There are no menus popping up.
Is this because of my custom firmware? Are there newer codes for Android 4.4.4?

Suitable downgrade firmware with "Hidden meny" options available?

Hello
Wondering if anyone could give me a hint of which stock firmware I would need in order to get options in the hidden menu available and thats compatible with Samsung GT-I8730.
Currently running Android-version 4.1.2 original stock firmware.
Trying to unlock SIM, using Chimera but gets stuck at 19%, when a popup-window tells me to enable Diagnostic Mode (DM) by using *#0808# or *#9090# or *#7284# in dial window
The two first options nothing happens at all and dialing *#7284# brings me to PhoneUtil with options UART, Modem or PDA, where PDA was default but there is no USB section available.
Also I would need the *#9090# to set Diag config to USB-value.
Am new at this and would be grateful for any help I can get
