Diag mode enables you perform advanced 00:22 functions like writing or restoring qcn, it can also allow you to backup qcn. Writing 00:30 IMEI etc. For you to enable diag mode, your phone needs to be rooted. We have a guide on how to 00:35 root using magisk. You also need to have installed your Qualcomm USB drivers. We 00:40 have a guide on how to do that also. You need to have setup ADB on the PC, we have a guide for 00:45 that. You need to have the Qualcomm Android device and USB cord. Now, once you have 00:51 these in place, you launch device manager and then you leave the phone powered on 01:06 once in device manager you connect the phone to the PC 01:11 don't forget the phone should be powered on and take note of what it gets 01:18 detected as. I have a detection under Portable Devices (Pi Pro). Now, to 01:27 enable diag mode, you launch command prompt. This is how I'm going to 01:33 launch command prompt 01:40 and then you jump to the adb directory although for some devices / 01:45 laptops you just hold down shift and then right-click and then select open 01:51 command prompt but I have power shell here so I'm not going to go through that approach. I don't have 01:55 command prompt here so I'm going to go through this method. Now, I'm going to copy my 02:00 adb address folder by right-clicking, selecting copy address then come here (to type) cd 02:07 space right-click to paste the address 02:12 I'm going to run that again... and then I press ENTER so now I'm in ADB directory 02:21 so I'm going to run this command adb devices to be sure I have a connection so 02:29 I've list of device detected. Now I run adb shell and then su . Now at 02:41 this point, if you are doing it for the first time, you might get a prompt on 02:44 your device to either allow ADB or to allow shell root access. Either ways, you grant 02:52 okay. Now, you're going to run this command to 02:56 boot into diag mode. I'll just copy it here; setprop sys.usb.config diag,adb 03:06 alright then you tap enter so that is 03:13 going to enable diag mode. To confirm, you go back to device manager. Its 03:18 going to refresh and then you should have an entry like this Qualcomm HS USB Android DIAG 03:26 901D so this is your device in diagnostic mode. Now to revert, that is to 03:33 take the device out of diagnostic mode, you run the same commands if you're starting 03:39 afresh but if you are where I am currently, you just paste the same command 03:44 but instead of diag, you change to mtp. it's the same command / procedure. The only 03:51 difference is mtp or diag. Since I'm in diag mode, I want to revert 03:56 back to the previous setting which was mtp (just change diag to mtp) and tap Enter 04:04 oh sorry, I have to run the commands afresh so adb devices adb shell su and then 04:23 I paste the command but change to mtp and then enter so I check device manager 04:38 again. I'm good, I have my device detected under portable devices once again so that's 04:45 how to enable or disable diag mode or diagnostic mode on a Qualcomm Android 04:50 device using adb -------------------------- Hire Or Consult Us https://www.hovatek.com/remote Join Our Training https://www.hovatek.com/training
