[Tutorial] How to backup & restore Qualcomm QCN using QFIL
Follow the steps below to backup or write QCN to Qualcomm Android with QFIL
See the video tutorial below or @ https://youtu.be/uiz2ymlITbAQuote:In this video tutorial, I'll be explaining how to backup and restore QCN of a Qualcomm Android device using Qualcomm Flash Image Loader or QFIL. For you to backup or restore QCN, you need to have boot the device or enabled Diagnostic mode on the device. We have a guide on how to enable Diag mode on your Qualcomm Android device. You also need to have installed your QFIL from QPST
Now, don't forget that the QCN helps you fix NV related issues like baseband issues, IMEI issues, network detection issues and rests alright? Now once you have the device in Diag mode, you connect it to the PC while still powered on then you launch QFIL. Once QFIL comes up, you'll see the device detected as Qualcomm HS-USB Android DIAG. So now this device is in Diagnostic mode and its detected correctly.
Now, you head over to Tools, click on QCN Backup Restore. Take note of the path where your QCN file is going to get saved to. alright and then you click Backup QCN. Once you do that, you'll see the status here. Just sit back and wait while QFIL backs up the QCN file. Alright! So QCN backup is complete. I have Backup QCN Succeed. You head over to the directory (mine is Hovatek folder). I have my saved_qcn here.
Now to restore, it's the same procedure; your device in diagnostic mode but this time around, you select Browse and then you select the QCN file which you intend to restore and then you select Restore QCN. You just wait while QFIL restores the QCN to the device. Alright! So we have Restore Succeeded. At this point, you can disconnect the device, maybe reboot and do whatever you wish to do.
So that's how to backup and restore QCN on a Qualcomm Android device using QFIL or Qualcomm Flash Image Loader
