Hello,
Your ROM appears to work well on my Wileyfox Swift (version 1). Using TWRP I flashed the radio, the ROM and GApps (in that order) from an external SDcard formatted Ext3 (as root). I arrived at that solution having recently upgraded my Asus Transformer Prime to KatKiss #15 (Nougat 7.1.1) where the same permissions regime worked. Question, is root really necessary?
First boot took a very long time. It's possible that I abandoned Cyanogen 14.1 and Lineage 14.1 too soon, both seemed to have hung for about 10 minutes before I gave up.
Does Titanium backup/restore work well on your ROM?
How do I restore root?
thank you.
