Galaxy S4 SGH-I337M running 4.4.2 - "no answer from phone" - GSM-Forum

BowChaser · 11-24-2014, 19:50

A complete beginner here. Just got my Z3X box. Installed all drivers. Device manager is showing everything is working fine. Trying to connect my rooted Samsung Galaxy S4 (SGH-I337M) running kitkat 4.4.2. Whatever I do I keep getting "no answer from phone" message. I tried both the USB cable and UART cable.
The code *#7284# to select 'MODEM' is not working on I337M running 4.4.2. That could be the source of my problems but not sure.
Anybody here can help? Any instructions how to properly connect I337M running 4.4.2?
Thanks in advance

*#7284# set back to PDA. *#0808# set usb settings to DM+MODEM+ADB. Win.

*#7284# is not working.
Is there a replacement for this code? Is that step needed at all?
Thanks

some phones dont use *#7284# any more, just use *#0808# in AP modem and MTP+ADB
Then *#9090# select log usb

This is what worked for me - if anyone has the same issue.

The phone has to be rooted with SU installed and Knox disabled.
*#0808# select 'DM+MODEM+ADB'
*#9090# select '[2]DM/DUN over HSIC[]'

Connect with USB cable.

I want to thank ecs87, abrapy, xerraco and rasgula for their help.
