Hi. I do not currently know which version my Cubot One was running before I installed a custom ROM. I have it on MIUI V4.8.29 at the moment and everything works hunky dory except the wifi and the bluetooth. When I try to switch them on, they just grey out for approximately 5 seconds and return to the "off" position. After rigorous googling, I was led to believe that the problem may reside in the hardware, but as I was walking home from school one afternoon, my phone randomly notified me of open networks that were available. I took this to mean that the wifi worked again, but when I got home, it had returned to the same off position as before. This gives me the inclination that it is in fact not a hardware issue, but a software issue of some kind. I think that, seeing as the build properties are the only things that were changed in the custom ROM updating, that THEY are the things I need to change back in order to regain the functions of wifi and bluetooth. I would appreciate any posting of the build.prop file for the original Cubot One stock ROM or suggestions that would inform me as to where I went wrong. To prevent redundant suggestions, yes, I've tried a full system wipe and reinstalling of several different custom ROMs (not the stock one, because I couldn't find it anywhere) and yes, I've tried turning it off and on again, several times.
Thanks, for your help,
