I have a KX-NS700 that is running on V4.3 (Rev. 330)that I plan on upgrading to V9 to unlock all it's features. According to a bulletin I read a prep tool is required to jump that far forward due to memory...

Upgrade of an NS700/G to anything higher than v4.4xxxx requires more memory than any previous version.
Due to this fact, you must run the NS700 New Firmware Preparation Tool prior to upgrading any NS700/G
system.


If it is the case does anyone have the prep tool available?
