Can't install latest OTA update

[vanitasvitae]

Hi
I tried installing the latest OTA update on my phone, but the installation failed. Is this update signed with another key? If so, is there a way to install the update over the existing system without losing installed apps/data?

@thestinger made some signing changes, so TWRP won't let you do your thing. If you would like to update without wiping, you will need to use Copperhead's current (as of yesterday) recovery image. Their web dev went AWOL, so it is not yet on the download page.

thestinger | apply update
thestinger | sideload
thestinger | I upgraded from cm-12.1 to cm-13.0 copperhead without a wipe

If you're coming from 12.1 and have gapps installed, you may want to read this. The opengapps pico package works here.

Edit: Made some corrections..

I'll leave this open for now so other people can see it. Uploading the recovery images is a priority but it's difficult right now.

The latest release is accompanied by a recovery image, and it will let you update without wiping/losing your data: https://copperhead.co/android/downloads?device=hammerhead.

Note that if you have gapps, it's a lot more complicated (just as it is with CyanogenMod). You need to wipe /system, install the new OS and then install the new version of gapps. There's still no need to wipe your user data, but I highly recommend backing it up first for obvious reasons.

So upgrading will be a bit complicated since you need to wipe /system with TWRP, switch to Copperhead's recovery to sideload the OS (since TWRP will be unhappy with the /data metadata mismatch, which won't happen again - but it was unavoidable to fully move to proper signing), and then switch back to TWRP to sideload the new gapps version because our recovery requires that everything is signed with our key.

The problem is still there for me. To switch from 12 to 13, I wiped everything (I set any flag in TWRP) and sideloaded the new rom. For some reason my old encryption password was still set, which I didnt expected but its OK :) Now I wanted to update to the latest Version (20151213) but I still get the error that TWRP cant install due to incompatible data. What do you suggest? Should I switch to Copperhead Recovery?

If the old encryption password was set, data wasn't formatted. Formatting data would fix the problem. Copperhead Recovery also wouldn't have the problem because it just validates the key, it doesn't do this check.

Ah thats unfortunate. I was so convinced that I formatted data... Is it a big deal to switch to Copperhead Recovery? Would it delete my fikes and apps?

[thestinger]

No, it won't delete anything. I don't think over-the-air updates work with it yet though so you'll need to sideload them for now. That will be fixed soon.

Was there again a bigger change to signing? Copperhead Recovery don't want me to update by sideloading.

The CyanogenMod-based operating system was dropped. It's now a new AOSP-based operating system with new signing keys. There's no upgrade path from one to the other, it requires a full wipe.
