NV Calculator (Non-Volatile) APK for Android

Do you want to add any GSM / WCDMA / LTE bands to your phone? Then use this app to calculate all needed NV (Non-Volatile memory) items.

This app is only useful for phones with a Qualcomm chipset.

If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

That thread is for Samsung Galaxy S5, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...

You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
