Thanks! I have To say, the recommended Brands are somewhat dubious…apperently none of the larger Brands want you to do this to their phones…

Well I guess that’s end of story then! Maybe still get rid of the phone then…

Thanks again for your help!

Everyone is saying that the bootloader can not be unlocked. However I see the option in the developer options of my phone…

This would be my first time doing anything with a custom ROM that is probably obvious…

But if the bootloader wouldn’t be the problem. That would still mean that there simply might not be a ROM available, correct?

Thanks! I will take the time to go through this!
