iOS Font Modifier

This tool helps you generate a PwnageTool custom bundle that will replace your Korean fonts in it.

1. Run the following command from this directory:

   ./update-HCRDotum.bundle.sh ~/Library/iTunes/iPhone\ Software\ Updates/iPhone2\,1_4.3.5_8L1_Restore.ipsw
   

   You should replace the argument with your version of ipsw.

2. Run ./install.sh to inject the bundle into PwnageTool.app

3. Launch PwnageTool.app to build your custom ipsw. You can remove CydiaInstaller bundle if you want your ipsw to be clean and not jailbreaked.

4. You will need redsn0w or other tools that can exploit the bootloader that allow you to install custom ipsw on your device. If you decided not to use Cydia when creating the ipsw, then you can get exactly the same iOS on your device with only a small number of files modified, e.g. default fonts.

Acknowledgement & Disclaimer

You can get PwnageTool from iPhone Dev-Team. Hamchorom font is provided by HANCOM for free individual use, and Hamchorom-LVT is an enhanced version of it by KTUG. VFDecrypt is a nice tool built by someone else.

This is free and unencumbered software released into the public domain.

Enjoy!
