Zip signature verification failed

[corna]

Hi!
If I try to update to the latest nightly in "BRNmod updates" i receive the "Zip signature verification failed" error in TWRP. If I disable the "Secure mode" everything works fine.
I'm trying to update from brn-12.1-20160106-NIGHTLY-thea to brn-12.1-20160107-NIGHTLY-thea on a Motorola Moto G 2014 LTE (XT1072).
Here's the log of the failed update

Btw, thanks for this ROM, it is exactly what I was looking for!

That's because TWRP checks the zip signature against it's own sign key, which is the sign key of TWRP and not BRNmod.
I haven't replaced the CyanogenMod recovery with TWRP because it's designed for OmniRom and currently breaks the build.

There are some TWRP builds signed with the BRNmod key at https://files.brnmod.rocks/TWRP/ if you want to enable secure mode.
You maybe also need to remove the cached update files on the sdcard (./OpenDelta/brn-12.1-*.zip) to enforce a full download as the delta update breaks the zip signature.

I've installed the BRNmod's TWRP but I receive the same error on the brn-12.1-20160108-NIGHTLY-thea OTA. Moreover, according to the OpenDelta's readme, it should also work without the signed TWRP:

Chances are that the recovery you are using does not have your public key built-in for whole-file verification purposes, and thus verification would fail. This is why OpenDelta also provides the capability to inject your public key into the recovery. This public key is provided to the recovery through the /cache partition, which non-privileged apps cannot write to.
