*.QCN - original qualcomm format file, compatible with QPST (qualcomm original programm).

Z3X SW use original format of file! this mean - you can read QCN by QPST and then write via Z3X, and QCN readed by z3x you can write via QPST.

What is this QCN, what mean, not sure what mean exactly QCN word, but for each understanding you can call them:

(Q)ualcomm (C)alibration (N)etwork file.

FAQ

Q>Which phones support QCN file for writing/reading?
A>All qualcomm based phones!!!!

Q> Why this file need?
A> If phone EFS erased, wiped - phone calibration erased - and phone not see network/not see 3g/2g/LTE network.

Q>QCN file same for all phones of same models?
A>NO. Exist lot of hardware revision of pcb and lot of different firmware for same phone, better to have collection of few QCN for same phone model, few times tested and after using same QCN 1st phone can work good and second phone can not work property.

Q>Can QCN fix UNKNOWN BASEBAND phone?
A>NO, But if you write QCN from wrong model, you can got UNKNOWN BASEBAND! WHY?!!
Becouse: You can write QCN only if phone modem work.
