How To Fix Samsung Galaxy S8+ Only Official Released Binaries Are Allowed To Be Flashed After Reboot Error
Problem: Dear reader, I’ve rooted my SGS8+ almost a year ago. 1 week ago I had to send my phone to the service center because of a dead pixel in my screen. The service center have replaced the screen and wiped unfortunately all the data. Of course I want to get rid of all the bloatware again and so I just tried to Root my phone. Everything went fine, I only forgot to place my sim card, which I placed after the root. And this of course asked me to reboot the phone which I did. Since then my SGS8+ would not boot anymore and gives the message (above the samsung logo): “only official released binaries are allowed to be flashed after reboot”, in red text. So I’ve looked around on the internet and can’t find really much about this message. Some “solutions” which for me don’t work like: I did download stock firmware from Sammobile, but if I’m trying to flash this firmware it will give me the message: “sw rev check fail device 4 binary. 2: I seriously don’t know what to do and I really hope someone could explain me some.. I would like to know why this message even occurs, is it like Samsung trying to stop people from rooting? And should I leave my phone now for 7 days? And will it boot up after? I’ve tried to check other forums but nothing really helped or no real solution for me. Hope I dont bother you guys. Kinds regards.
