rooting - How to root cyanogen OS? (On Wileyfox swift)

I would like to know how to root Cyanogen OS on WileyFox Swift

Answer

Simply by flashing SuperSU.¹ There's a thread at XDA explaining the steps:

1. download SuperSu


2. save it to your external sdcard


3. enable developer options (settings - about - click mutliple times on the build number)


4. enable OEM unlock in the developer options settings on the device


5. reboot Wileyfox Swift into fastboot mode: with the device powered down, hold the Volume Up and connect USB


6. 
   

   to unlock the boot loader (WARNING!!! This wipes your user data!!!), type from your computer:

   
   

   fastboot oem unlock
   fastboot -i 0x2970 oem unlock-go
   fastboot oem unlock-go
   
   



7. 
   

   download latest recovery image from Cyanogen

   
   


8. 
   

   to boot the custom recovery, on your computer type

   
   

   fastboot boot .img
   



9. 
   

   install supersu update zip from recovery menu (choose zip from extenal SD)

   
   
   


10. reboot and enjoy root access

Note that steps 6 and 8 require the matching drivers being installed on your computer if you run Windows.

Updating a rooted Swift

Also note that "incremental updates" are no longer working with the device rooted. Please see how to update rooted fox at XDA for alternatives. Each of those updates will probably break root, so you'll have to repeat the above procedure after each update to regain root access.

Alternatively, you can also switch from CyanogenOS to CyanogenMod, which includes root access.
