@chrmhoffmann Is the ROM pre-odexed? That would be an issue for patching it with tingle to get signature spoofing permission for microg.org. Tingle (and any other available patcher, I guess, @ale5000) only supports non pre-odexed ROMs, :S
FYI: Obviously Lineage for microG will still work because it builds the ROM from source with the required permissions, but modding an official LOS ROM is still more flexible —and always will be. Modding also doesn’t come up with more nasty trust-your-builder issues, since Android can’t be built reproducibly.
