Before you download the ZIP files, please read the H3xx Firmware Instructions. It is now widely recognised that flashing a US H320/340 with Korean firmware version 1.20 or 1.25 causes no harm However, you do lose the DRM capability if you want to transfer DRM music files on to your H300-series, and if you flash back to US firmware it will still not work. In general you are advised not to use any Korean firmware versions earlier than 1.20.
