CyanogenMod on Xperia Z1 compact: Amami or Yuga I have in stalled CyanogenMod (CM) 12.1 on my Sony Xperia Z1 compact -- according to the CM website the name for that device is amami. The OS (Cyanogenmod version) that it runs, very much to my satisfaction, is 12.1-20150424-UNOFFICIAL-amami.

However, updates for amami that are downloaded, for installation in recovery mode, are refused because the ZIP installer (in recovery mode) says that my device needs a yuga update not an amami. 

While the name yuga is reserved for Sony Xperia Z phones, which may be a generic class into which the Z1 compact also falls, I had expected that the amami updates, which are specifically for my device, would be a better fit.

Does anyone know how I can make the amami updates work on my amami phone with an amami ROM on it, instead of asking for yuga?
You are running an unofficial build/port of the rom. If You must use official N build of the CM rom you should first change to official CM rom.
 You can't simply jump from some xyz rom( that's what UNOFFICIAL rom is) to official CM Nightly(N) or stable (Milestone, M) rom.
 Also if you are happy with your current non-CM rom, you may continue using them. You have to get updates for it from the developer whose rom you are using. Check for updates at XDA-Dev or whatever other development site from where you got your rom.
 If you wipe and load official CM nightly for your 'amami' you will be able to receive and install updates from CM.
