Support for new Exynos series

[iman432]

Hi all,

There is any plan for adding support for new Exynos series(phones like Galaxy S21,S22)? I saw in #27 there is no any signaling for 5G Exynos (also i cant get by S21) but we can get signaling by Shannon DM(even old version) so i think should be a way for scat too, thanks.

Although I have Exynos derivative (Pixel 6) atm, but I couldn't give any estimations yet. It is a matter of enabling/disabling diag output though.

I've had some success getting the Pixel 6 to start logging after digging through its init.rc scripts.

#!/bin/bash

function adbsu {
    adb wait-for-device
    adb shell su -c "$1"
}

adbsu "resetprop ro.bootmode usbradio"
adbsu "resetprop ro.build.type userdebug"
adbsu "setprop sys.usb.config acm,dm,adb"
adbsu "persist.vendor.usb.usbradio.config dm"
adbsu "start modem_logging_stop"
adbsu "stop DM-daemon"
adbsu "start DM-daemon"
adbsu "start modem_logging_start"

But it needs root for modifying init.rc, I guess there is a way without root as Shannon DM is working with new Samsung phones without root or modifying any files on OS.

Yes that is true, this method requires a rooted Pixel 6 with Magisk (for resetprop). It doesn't involve modifying init.rc, those were just used as reference to figure out which props needed to be set.

See the last comment of #27 if you managed to expose the DM interface through USB.
