2) After unpacking open CPB_Unpacker.exe

3) Copy cpb_unpacker.exe in the same folder of firmware

4) Copy **********.cpb filename and paste in first input field of cpb_unacker

5) After that click the bottom left (down) will see the extraction of the system. img, boot.IMG.........etc in the same folder


1) After you have done changes you wanna repack your firmware
2) Open CPB_Unpacker.exe
3) After that click the bottom right (up) will see repacking of the system. img, boot. img......etc into the CPB file in the same folder
4) That's it
