This is why the preset restoring isn't working. It can't find this method within your MTCRadio.apk. It's probably something that was added to a later version of the Radio, since I did testing against KGL 2.03.
If you don't want to flash a whole system update, you could try replacing the MTCRadio.apk in /system/app with a newer one.

Hello! Thank you so much for your information. I'll try to replace MTCRadio.apk (1.77) with MTCRadio.apk (2.03), I'm not sure it will work, then I'll try the application from 1.86 or 1.92, something like that. If it doesn't work, I'll think about flashing...
