Well, my question can be simplified as:
since 2) has to be implemented anyway, why not levaraging it to implement
an alternative to 1) ?
After device failure:
1) boot a read-only minimalistic partition, that can connect to servers and
download (and install):
a) user specific information present on cloud (user data, list of
installed apps, cgf for each app, etc)
b) last known base OS
c) extra apps that the user had installed.
2) reboot the device into the newly reconstructed setup
This would also take care of a gap you currently have: keeping in sync the
It could be easily re-flashed as part of the reconstruction process.
Same goes for whatever other peripheral that might have non volatile FW.
Same process could be used to perform the so called "factory reset":
have a blank user with no apps/data configured.
So, if the process is performed through a "safe" partition, it doesn't even
require a PC,
only connectivity of some sort.
