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?
