Since large part of us might get their Z2s this week (hopefully including me :silly, I'd like to know what options we have to make our Xperias secure with soon-to-arrive custom ROMs.
From what I managed to find, the most convenient option (at least theoretically) would be to:
- unlock bootloader
- flash custom recovery
- flash custom ROM
- reflash stock recovery to prevent lockscreen bypass and adb access in general
- relock bootloader to prevent flashing custom recovery and regaining adb by potential attacker.
- then if needed, reflash recovery online if rooted, reflash new/updated ROM, reflash stock recovery back
Now, I've read that Xperia Z2 (other Zs probably as well) will softbrick with locked botloader and custom ROM/kernel, rendering this method useless. Am I right?
If yes, what other options do we have?
