Ok i contacted support, this is the answer(s) i got:

"Hi,

Thank you for your message!

After 7 years and 34 OS updates, we have decided to discontinue the support for Jolla Phone (a.k.a. "Jolla 1") in November 2020. OS version 3.4.0.24 remains the last one available for Jolla Phone.

This decision implies that we will also stop providing customer support for this product. We recommend seeking help from our community."

and

"Hi,

Thank you for your message!

Unfortunately we cannot help you with the security code. Our service partner went bankrupt last spring due to Covid and we don't have any other partner to help with this. "

Just for the records and for anybody who will most likely end up in the same boat.
I ask here again (with very little hope): is there anything i can do?
My bootloader is also locked :-/
