if the radio is the only thing you needed to change for CM then u can flash it back to 6.35. wipe your CM ofc cause according to your story it's not compatible with radio 6.35.
first determine the type of ROM you want, and then find out what version SPL and radio it requires.
superwipe your CM ROM and then flash your SPL and/or radio to meet your new ROM's requirements. Then flash your new ROM.
