Hi. If 4MeKey actually works to totally remove any iCloud ID/Apple ID of an iPhone 5c that's been donated, there's no way to contact the former owner to remove the iCloud/Apple ID, does Tenorshare's free download of their 4MeKey app, make you pay first before it'll totally remove all Apple ID...
So a few days ago I was using my iPhone 6s when it randomly decides to shut down and try to reboot, except it doesn't get past the Apple logo (stays on it for 3-4 minutes, then the screen just goes off). I've been able to get it into Recovery Mode, and have attempted to use ReiBoot to kick it...
