Signature error on a Samsung Galaxy S10

Installation Help
1

Hi!

I’m presently trying to install Iodé on a Samsung Galaxy S10, following these instructions. It works for the 6 first steps, but when I launch adb sideload, the process is exited with an error which says failed to verify whole-file signature. What did I do wrong?

Thanks for your help!

So you are in the iodéOS recovery and get that error? I’m trying to remember if you would just need to accept the warning of the signature not matching, but I didn’t think that would be the case?
