we have here a Swift that is stuck on a starting screen since an attempt to downgrade from Cyanogenos 13.1 to Cyanogenmod 12.1. Bootloader ist unlocked and to my knowledge only the recovery was flashed via fastboot.
As soon as the USB cable is connected, the screen goes on with "Wileyfox(with logo) powered by android" and remains there.
Luckily fastboot works, but I can't get into recovery. Neither by selecting "reboot into recovery" from fastboot nor by "Vol-" + "Power".
I tried to reflash Cyanogenos 13 via fastboot as it was suggested in several threads (i.e. unzip and flash the different files step by step). Fastboot always stated success, but no luck... Still the same starting screen.
I even tried flashing TWRP recovery, no change either.
Is there something else I can try?
Thank you all
SOLVED: I was persistent: one other threads regarding a lenovo phone suggested to hold down Power and VolDn continuously for several minutes. After about a minute or so and multiple (min. 15x) power off/ons to the "powered by android" screen, I finally got into TWRP! After a format /data I was able to flash the desired CM.
I hope this helps others with similar problems
