p.s. Yandex Disk - is a Cloud File storage, like Google Drive and others. If your downloading speed limits to 64 kbps in some reasons, register your own Yandex account (it's free), save file to your own cloud account (Yandex Disk) and download it from your Disk account without any speed limitations.

p.p.s. I didn't try to build CM for Idol 4 6055 yet, because first i need to buy a "test device" for an experiements. But when i do it, of course i will try to build.
