QCN from a qualcomm android phone using miracle box

So in order to do this, you must enable DIAG mode on the phone
00:29
So we have a guide at the forum on how to enable the DIAG mode on qualcomm
00:36
You can check it out
00:40

00:49
So adb devices
00:56
adb shell
01:03
su
01:09
So this is the command to enable DIAG mode
01:18
Okay so here you go, the phone is now connected in DIAG mode
01:24
Now we need to launch miracle box
01:51
On the miracle box interface, click the qualcomm tab

Click port

Now tick the checkbox beside read QCN
02:34
Then click the start button
