Hi, I have this same issue on my T8-S Plus: in OTA Updater it says ROM version 1 (Oct 30, 2015) but in the Updates section below it says “Error fetching update info: No peer certificate”. I have gone into the OTA app and cleared the data; I have done a factory reset; still same message.
Interestingly, if I go to Settings>Other>System Update>Online Update I get a message saying “Check Failed! Check Your OTA Servier Argent”.
All started when I was getting messages in a movie app saying “This app isn’t compatible with your device anymore”.
Any help gratefully received, thanks.
