temporary Telnet - Red only - RTSP firmware

[Vendo232]

I was able to enable temporary Telnet using this process. I wanted to install WyzeHack Stream and it did install it but I assume due to temporary Telnet it does not work after reboot.

I`m unable to enable the telnet permanently per this instruction

To make it permanent, all you need is telnet into it and modify /system/init/app_init.sh by removing the comment before line /system/init/run_telnet.sh &

because the app_inst.sh is REDA ONLY. any idea what to do?
