Important Notice
  • NCK Pro Box requires a hardware box in order for the module setup to work
  • If you've chosen to go with a loader version (no box required) then it might get flagged by your antivirus. You're responsible for choosing to ignore the warning
  • ¬†Avoid restoring a different model's QCN as this could brick the device
  • Its recommended you backup your currenct QCN / EFS before flashing another just in case the newer one makes the device worse
  • Remove the device from Diagnostic (DIAG) mode after this procedure so your Qualcomm device can connect in other modes like MTP

Quote:In this video tutorial, I'll be explaining how to backup or dump a Qualcomm Android phone's QCN file using NCK Pro box. QCN manages your phone's NV items. That includes your IMEI, Baseband, WiFi & Bluetooth address, basically anything that involves the phone's radio is managed by the QCN so if this gets corrupted, you'll have a case where your phone can't detect signal or you begin to have NV issues ok? So its very important you backup this file so you can always restore it if it gets corrupted.

For you to follow this guide, you need to have the NCK Pro hardware box. You need to have set it up, we have a guide on how to do that. You need to have installed your Qualcomm drivers, we also have a guide on how to do that. You need to have the phone which you want to backup QCN from and you need to have rooted the phone.

The phone should be switched on with USB Debugging enabled. Phone connected to box, box to PC.

Still under the ADB-FASTBOOT utils tab, click on Enable Diag. This is to enable Diagnostic Mode (rooted phone) Now, you might get a prompt on the phone asking you to allow shell root permission, accept. Keep checking your phone's screen during this process, you'll get a prompt to allow root permission. Once you've done that, you should have something like this. To be sure, you can checkout Device Manager. My phone is still connected to the box so it should be detected under Device Manager. You should have the Diag Mode here. Great! this is it. This shows that the phone is in Diagnostic Mode.

Alright! Come over to the IMEI-QCN tab. Now, you're going to click backup here. In this Window that pops up, what you'll want to do is to navigate to the location where you want to save the QCN file. You can name it whatever you want to name it. Navigate to the location where you want to save your QCN file. Set the name then click on Save.
