Serously for how long do you think that will be possible? Fact stand Sony has pissing in the boat and Xperia series is not an open platform. When I used FP2 fastboot WAS the official flashing tool same goes for other open android phones such as nexus I guess. I don't want to use some crippled binary from random company that ponly work for broken OS'es like windows. Sony are just same garbage as samsung/iphone and now trying locking in the user. Xperia is over for me I will not spend a second try install SFOS on the phone. I will probably sell the phone later (unrooted). So sick and tired of locked in shitness. If I did know above a month ago I would not sell my FP2. Instead keept it and wait for: https://puri.sm/shop/librem-5/ Indeed I just contributed for that phone. If people want true open phone they should also support librem 5. Sony plain dead for me. Over and out.
