There’s no hybris-recovery for 5.0.0.62 for C2 either.
Maybe it’s possible to ssh into the half-booted device (Sailfish OS logo) via USB.
Otherwise you definitely should contact customer support. They are friendly & willing.
I have now reverted the offending changes and updated the package again. Installed it on my phone, rebooted, and all is good.
The timer now triggers the service once a day, but the script only rebuilds the hosts file from cached files + black/whitelist, until the cached files are older than interval (default 7 days); only then are the lists fetched again.
Please see /usr/share/doc/hosts-block/cfg.sh
I will re-implement the auto-update feature as soon as I have time to thoroughly test it (weekend probably).
