====== Fixing TWRP boot loop on Wileyfox Swift ======

====== Situation ======
LineageOS 14.1 installed, TWRP 3.0.0 installed, phone working properly.
After an OTA update gone wrong, the phone did not boot into system but only into TWRP recovery.

====== 1st Try ======
Based on [[https://www.reddit.com/r/LineageOS/comments/5riech/how_fix_twrp_recovery_boot_loop_after_lineageos/]] the first try was to install a newer version of TWRP. This resulted in the phone unable to boot at all.
===== Resolution =====
  - Boot into fastboot (VOL+ and Power)
  - Flash TWRP 3.0.0
  - <code>
fastboot erase recovery
fastboot flash recovery twrp-3.0.0-0-crackling.img
</code>
TWRP 3.0.0 available again

====== 2nd try ======
Flash most current version of LineageOS --> no change

====== 3rd try ======
