To repair the IMEI on Android devices running on Qualcomm Chipset, you can also write the same existing IMEI number on your device or you can write a new IMEI number on your Qualcomm device. You are required to have 16 digits of the IMEI number and fill it in the IMEI columns.

What is the QCN file?

QCN stands for Qualcomm Calibration Network file

Basically, the QCN files are built into all the latest Android mobile phones. QCN is the main and sensitive file of the network, hidden in the deepest core of the mobile phone's internal memory file system (in the efs folder, where all information of imei and baseband are saved).

All qualcomm based phones supported QCN files, especially all SAMSUNG Galaxy and the latest ANDRIOD mobile phone devices which are available in the market.

If phone EFS is erased, wiped - phone calibration is erased - and the phone does not see network/not 3g/2g/LTE network we need to write a QCN file to repair these problems.

QCN file the same for all phones of the same models?

No, there are a lot of hardware revisions of the PCB and a lot of different firmware for the same phone. Better to have a collection of a few QCNs for the same phone model, a few times tested and after using the same QCN 1st phone can work well but the second phone can not work properly. So the conclusion is this one qcn file is not for all mobile phones.

Can QCN fix the UNKNOWN BASEBAND phone?

No, but if you write QCN from the wrong model, you can get UNKNOWN BASEBAND! Because you can write QCN only if the phone modem works. If you see UNKNOWN baseband on your phone it means the modem does not work properly.

Where I can get the QCN File?

You can download QCN files from the internet but the best and most professional way is to copy or read a QCN file from a fresh mobile phone and not from a branded mobile phone.

How will QCN files affect the imei of mobile phones?

No, if you using Z3X products for writing QCN, this will not touch the NV and IMEI of your mobile phone.

If we see a CERTI(FAIL) problem we can fix it by writing QCN?

No - CERT (signature for imei) does not have any relation to MODEM CALIBRATION.
