TWRP backups will restore but not boot, only bootloop
I'm not sure how you installed LineageOS and others, but maybe downloading a stock Wileyfox image and following the steps below would work?

WARNING: I did not try it!!

Image found here: https://forum.xda-developers.com/swift-2/how-to/marmite-android-7-1-1-tos118c-fastboot-t3605101 (probably use the fastboot one)

Steps to revert to stock state (copied from here: https://forum.xda-developers.com/wileyfox-swift/general/7-1-1-swift-update-t3592328/page6 ):

fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
#fastboot flash hyp hyp.mbn
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash splash splash.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery revovery.img


Also, you seem to have installed the lineage-14.1-20171002-nightly-crackling image intended for an old swift (crackling), on the newer swift 2x (marmite). That's probably why it didn't boot, right?
