Note: If you’re using a custom ROM you can try the dialer method but most likely you will get nothing after dialing the code. If this is the case you still can enable the Diagnostics mode but you need root privileges. Open a Terminal Emulator app and type this:

su
setprop sys.usb.config diag,adb

Done. You’ve Enabled Or Disabled Diag Mode on the Redmi Note 10 Pro device.

Open QPST Tool to Backup QCN

  1. Now open the QFIL and connect your device to the PC with the USB cable. Redmi Note 10 Pro should show as connected in Diagnostics Mode.
  2. Now tap on the Select port and select your device and press OK.
  3. Tap on the Tools tab and select QCN Backup Restore from the drop-down menu.
  4. In the next window,  add any name to the QCN file with the .qcn extension. Make sure to Select the “multisim” option and press Backup.
  5. Once the backup is done, check the generated file size. A normal backup is around 310Kb, if your file is significantly lighter you can suspect a damaged file. In this case, I suggest installing stock rom and use the dialer method.
