So here my problem.
I have bought a Jolla1 over ebay.
The LCD was broken no picture was to see.
I changed the LCD-Screen.
The jolla boots fine, but it is locked with a device lockcode.
I tried several workarounds.
Telnet recovery or shell it is not possible because not known device lock code.
i tried also fastboot mode with booting recovery images.
error :
booting...
FAILED (remote: access denied. need privilege!)
finished. total time: 0.645s
In the early SFOS could have bootloader unlocked, just like any otter Android Device (fastboot oem unlock)
Later, this was i think, removed option from the bootloader.
But, we dont have any fastboot flashable images to flash .
