While you are tinkering around with your device, your baseband could easily become null, unknown or invalid. This usually happens when the wrong ROM configuration is over-written over the original one. But worry not, there is an easy fix for this. Fortunately, there is a tool which allows the user to quickly fix this issue on their Qualcomm powered Android device. Using the QCN Rebuilder, you can write correct IMEI number for any QCN file. Now, let’s get started with the guide and hey, we have also provided a link to download QCN Rebuilder Tool.

QCN Rebuilder Tool – What is it?

From the above, you might already have a base idea on what this tool and what it does and how you can use it to get out of tricky situations. If you want to know more about the tool, then read ahead as we take deep dive into the tool and its use cases.

IMEI is short for Internation Mobile Equipment Identity and this is the magic number which makes all the devices unique (to put things into context, we have literally BILLIONS of mobile devices!). The very same device that you own is also sold in different parts of the world and then there are different variants of the same model and yet, all of them are still very much unique – thanks to IMEI number. Added to this, the IMEI number will also come in handy while tracking your lost or stolen device. You can easily find this IMEI number on the retail box of your device or you can simply dial *#06# on your smartphone’s dialer (irrespective of the phone/OEM; this is universal) to get the IMEI number of your device.

If you are one of the many power users of Android, then there is a good chance that you would like to mod your device like installing custom ROM, MODs, custom recoveries and what not. There are a lot of things that could go wrong when installing a custom ROM and one among them is that you can mess up the IMEI number on your device. Without a proper/valid IMEI number, you cannot track your device if it is stolen or even sell your device.

With the QCN Rebuilder tool, you would be able to

  • Fix the invalid IMEI number on your Android device due to wrong ROM installation
  • Simply change the IMEI number from QCN.
  • Convert the IMEI to HEX.
  • Repair the Qualcomm IMEI to Qualcomm QCN.
  • and much more.

This tool is incredibly tiny and easy to use and what more, it is portable. This means that there is no need to actually install the tool on your personal computer rather you can simply run the tool by opening the .exe file on the go.
