I bought a fair phone 2 when I lived in Germany in 2016. Got a software update when I moved back to Australia. Bricked it. The kernel debug interface has no standard header, and required a fine pitch soldering iron header. I rented a German post box to send it to, as you need a European address for support. I tried to send it twice, and it was refused by German customs. I gave up and now I just buy cheap second hand Motorolas and unlock the bootloader, put lineageos on them. I think giving new life to discarded devices is more ethical anyway.
