Does the 'In Start' menu exist on WebOS 1.4

[denisuu]

Hi all,

I'm wondering how you can get into the service menu (In Start) on an old LG Smart TV (42LB630V) running WebOS 1.4.  I have a Samsung Galaxy S6 (SM-G920F) with a IR blaster, I have tried sending '0x04FB 0xFB04' to I which should be IR code to enter the menu, but that doesn't work.

I have also tried entering it with the SSAP-Web, but I get:

error: 500 Application error
{"errorCode":-101,"returnValue":false,"errorText":"\"com.webos.app.factorywin\" was not found OR Unsupported Application Type"

The SAPP-Web app does works though, because the TV does respond to Get info

{
    "returnValue": true,
    "product_name": "webOS",
    "model_name": "HE_DTV_WT1M_AFAAABAA",
    "sw_type": "FIRMWARE",
    "major_ver": "05",
    "minor_ver": "05.90",
    "country": "omitted",
    "device_id": "omitted",
    "auth_flag": "N",
    "ignore_disable": "N",
    "eco_info": "01",
    "config_key": "00",
    "language_code": "en-GB"
}

The reason I want to access the menu is because I've enabled DEBUG mode on my TV through the NVM method and I want to enter a root shell trough UART to enable SSH and root access.

Gaining root access through NVM:
