I've a wileyfox swift (crackling) and I've installed LineageOS 14.1-20170213-NIGHTLY-cracking + GApps through TWRP 3.0.3.
The problem is that when I try to update it through the UI or manually (downloading the .zip file from https://download.lineageos.org/ and installing it from the recovery) TWRP returns an error (status error 7).
I tried to downgrade TWRP to the 3.0.0 version but nothing changed.
How can I update my phone without wipe everything?
