zip signature verification failed #16

Closed benediktg closed 7 years ago

benediktg commented 8 years ago

As I tried to flash the freecyngn-flashable-cm12.zip on my Android device (Samsung Galaxy S5 with Cyanogenmod 12.1 nightlies and TWRP 2.8.7.0) the process aborted because of an error E:Zip signature verification failed: 1. Lastly I could apply freecyngn by disabling the zip signature verification – could the flashable zip be signed by the developer?

I have exactly the same issue on a device running the latest CM12.1 snapshot (not nightly) and the new CM recovery. I'll see whether the CM recovery supports disabling signature verification at all.

Seems like there's no option in the new CM recovery to disable signature verification. So I'm out of luck here.

I manually removed the packages running the shell script commands through adb shell later (after adb root && adb remount). Is this sufficient? I read in the comments of another issue that it's important to flash freecyngn before the first reboot after CM got flashed. Why is that? Does the first boot process write non-free apps somewhere into the system where it's impossible to remove them from afterwards? I'm really curious about that.
