In the last few days, my N7100 (which I gave to wife) has gone twice in bootloop by itself while idling.

Every time TWRP showed that the phone was unable to mount /efs.

By restoring the efs partition from a nandroid backup I could restart it again both times.

The double failure of /efs at less than a week distance makes me think there's something very wrong in the phone.

After first efs restore I did a factory reset and installed only 2-3 fundamental apps, so I don't think it's the fault of a rogue program.

Do you think my device is at the end of its life cycle? Is there anything I could do to fix it?

Thanks.
