This is disappointing.

On the one hand Jolla encourages hacking of the device to developers (which are probably the sole user base at the moment?). On the other hand they now want to secure the device for the normal user and take away functionality we saw as a feature. I understand the security concerns here. However, without any way to easily reset the device by flashing an image, this makes me more cautious with any experiments…

At least it seems like the old mmcblk0p17 seems to be the same for everyone – the checksums published earlier in this thread matched.
