It's been a while since I entered the Diag mode in my G900P. I recently upgraded to lollipop. I tried to enter the diag mode but it can't be recognized in devices manager and even DFS. When i change the device into MTP+ADB , I can here the sound of pluging a device but when I change it th DM+Modem+ADB, I hear nothing just the disconnecting device sound .Does the lollipop system has anything to do with the problem??

Anyone may know why and how can I fix it?


please help

Thanks

    Totally different than Samsung diag, you may want to look in the Sony/Ericson section.

    You must at least enable ADB mode, under Settings > Developer Options > USB Debugging ... then enter this:
    adb shell
    su
    mount -o remount,rw /system
    cd /
    setprop sys.usb.config diag,acm,adb
    setprop persist.usb.eng 1
    setprop usb.rndis.enable 1
    echo 1 > /sys/class/usb_composite/modem/enable
    echo "persist.service.adb.enable=1" >> default.prop
    echo "persist.service.debuggable=1" >> default.prop
    echo "persist.sys.usb.config=mtp,adb" >> default.prop
    echo "persist.service.adb.enable=1" >> /system/build.prop
    echo "persist.service.debuggable=1" >> /system/build.prop
    echo "persist.sys.usb.config=mtp,adb" >> /system/build.prop
    reboot

    Note: If not rooted try it without the su/mount commands, and also some of commands might fail which is fine.
