I have a XG-100M/CH721 that refuses to keyload. KFD Shield has no problem loading the 100P with the same keys. I have a OEM 14002-0143-10 REV2249 cable that was modified from the MX connector to Hirose. I go to Keyload - KVL and hit menu, the radio just sits "Idle". I can't read or load any key information. Below is the firmware versions read out just now.

Obviously, the firmware update on the mobile is a bit different than the portable, so I didn't go monkeying around there, afraid to brick it.
I have firmwares: 100M XLP R06T02, CH271 Main R07G17, DES-CFB R04B03 & HALM R04A01
I'm not even sure if firmware reflashes would do anything. Any help will be great. I do have 35, 37 & 45 in the feature set, so I "should" be good to go.
