on my Ray LegacyXperia cm12.1 runs pretty fast. So this is very fine!
Thank you guys. You have done a really great job!
But I still have some open issues:
A) LegacyXperia custom recovery does not seem to support Nandroid at all: there is no 'backup and restore' option of the recovery included in the Kernel. Why not? (I suppose there is none in the CM11/13 kernel as well.)
And where can I get and flash a sys recovery WITH this feature here?
B) Furtheron there does not seem to be supported any version update functionality so that even any bug fix will cause the loss of the current installation, right?
Or may I overflash an update without loosing the whole existing configuration (by avoiding format of /system, /cache and /data)?...
C) Is there any other ROM compareable with LegacyXperia but supporting A and B?
Thank you very much for your help and advices!
A) CM11 uses clockworkmod recovery which supports nandroid backup and restore. I don't know about CM12, ask there. Anyway, CM12 is no longer supported so you should update to CM13.
B) You can dirty flash within the same CM version without wiping data and system (just wipe dalvik-cache and cache). You won't lose apps and app data this way.
