bummer. So I received my Xperia X F5121 from Amazon today and of course wanted to flash the community image right away. I did the TA backup and wanted to unlock the bootloader. As described in the guide, I went to check the status in the service menu and there it says under "Confguration": "Bootloader unlock allowed: No". The way I understand it, it's not possible to unlock the bootloader and flash SFOS, right?
This really puzzles me, since it is a full priced retail version. Is there a possibility to unlock the bootloader that I'm missing (like flashing another ROM first) or do I have to return the phone?
