How to update an encrypted FP2?


This week, I have encrypted my FP2 running Lineage 14.1 (official nightly 20180425) using a password (not a PIN code, not sure if it is relevant).

Just now, I trid to update to nightly 20180503, but I don’t have access to my /data partition from TWRP 3.0.2. My decryption password was never asked and I have this in the logs:

Updating partition details…
Failed to mount ‘/data’ (Invalid argument)
Unable to mount storage
Failed to mount ‘/data’ (Invalid argument)
Full SELinux support is present.
Unable to mount /data/media/TWRP/.twrps

So, how i can do the update?

Update TWRP. See:


Hum. I have installed TWRP in february from, so I should already have the latest version. Don’t understand why TWRP say «3.0.2» on the welcome screen.

but I will try to install it again

Now TWRP display 3.2.1 and the decryption work well. Thank you!
