What is the QCN file?
QCN stands for Qualcomm Calibration Network file
Basically, QCN file built-in in 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 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 erased, wiped – phone calibration erased – and the phone does not see network/not see 3g/2g/LTE network we need to write QCN file for repair these problems.
QCN file same for all phones of same models?
No, exist a lot of hardware revision of PCB and a lot of different firmware for the same phone. Better to have a collection of a few QCN for the same phone model, a few times tested and after using the same QCN 1st phone can work good and 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 so it means the modem does not do work properly.
Where I can get QCN File?
You can download QCN files from the internet but the best and professional way is to copy or read a qcn file from a fresh mobile phone active and not from branded mobile phones.
What will QCN files affect the imei of mobile phones?
No, if you using Z3X products for writing QCN, this will not touch your NV and imei of your mobile phone.
If we see CERTI(FAIL) problem we can be fixed by writing QCN?
No – CERT (signature for imei) does not have any relation to MODEM CALIBRATION.
