The subject returned to me after successfully serving as a LineageOS phone. Still in a good shape - only place to show a wear is on/off button. See the previous thread.
So if anybody is interested, I can give it away.
Currently running Sailfish OS 4.5 Struven Ketju but it is also very well supported by UBPorts.
F5121 Graphite Black; Sl 1302-3093 Rev 4 2G/3G/LTE
In original box with all included accessories (charger, cable etc).
Bootloader is unlocked and Sailfish X installed.
Phone will be in a clean Sailfish "factory reset" state - you can set it up and tie to your Jolla account.
Phone is still in Tallinn/Estonia, if shipping is needed, you have to pay shipping cost - it is approximately 11-30€ inside EU.
If you are interested then please PM or answer in this thread.
