Mi 10 Qualcomm Diagnostic Mode (Diag Mode) for Qualcomm Product Support Tools (QPST Flash Tool)?

[theVerge]

Hi MiFans,

What is the correct way to get into diag mode on Mi 10/Pro and backup QCN? QPST says Unknown Phone and No ESN.

This one didn't work:

adb shell
su
setprop sys.usb.config diag,adb

On my MI 10 Pro I have set both sys and persist to preserve settings over reboots:
adb shell
su
setprop persist.vendor.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb

Did you guys lose EFS, because it is recommended to backup

No. Settings those properties to enable diag port(s) has no effect on EFS

I tried this on an Ultra, but now my USB connection no longer works on the phone. Any ideas how to correct that?

EDIT: I believe that reinstalling the rom has solved the problem.
It would be nice to know how to get the diagnotic mode working - and QPST for that matter.

With sdn 865 it's not easy. I think few people do it for now. For imei repair, only #2 is available. Waitig for an en rom to fix #1 imei repair issue. You guys must backup efs.

How to backup if it's not possible to get the phone properly recognized...?

setprop persist.vendor.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb

Can you run a setprop command to revert it?

setprop sys.usb.config rndis,diag,adb
This one creates a 902D driver in port in dev manager but it won't work for me in qpst. I am running AOSP so that might be why, it might work with MIUI
