Unpack

Write XML output to file "ctce8_F663N.xml"

Unpack a ZTE cfg file to specific file out.xml:

$ ./ztecfg -u ctce8_F663N.cfg -o out.xml
Write XML output to file "out.xml"

Pack

Pack to ZTE cfg file with original cfg file and xml file:

$ ./ztecfg -p ctce8_F663N.cfg new.xml
Write CFG output to file "new.xml.cfg"

Pack ZTE cfg with a specific output file named out.cfg:

$ ./ztecfg -p ctce8_F663N.cfg new.xml -o out.cfg
Write CFG output to file "out.cfg"

Warning

The unpack process will check the CRC checksum of both the file header and the block header to make sure the cfg file is valid. Also the pack process will write back the checksum to the cfg file.

If the cfg file cannot be unpacked, it might indicate that the cfg file is incompatible with this tool. Under such circumstances, please DO NOT try to pack it back, cause it might brick your optical modem.

Always backup your configurations before you do any modifications to your modem.

This tools had been tested only on ZTE ZXHN F663N, but it should be working on any ZTE ZXHN series optical modems with a cfg backup file.

Use at your own risk, the author will not take any responsibilities of the damage to your devices.
