Live tooting: first ever flashing of a smartphone (Sailfish OS on Sony Xperia XA2)
No, damn, I'm stupid, I literally typed
sudo fastboot oem unlock 0x<my unlock code>
but I need to specify "oem"!
But what's the vendor ID? The Jolla instructions propose
-i 0x0fce
in their example.
Gonna have to investigate that...🕵️ 🔎
