I recently realized that people with hankou devices can't install custom wuhan firmwares
I know 10 people who bought their Mb3 recently and all of them have the same problem, udpate cancels at 99 or 100 percent (All of them)
I myself have wuhan and it's okay, also some other users with hankou are okay but around 10 people can't install them (they tested everything, nothing works)
Custom and even official firmware of wuhan won't install
but official hankou firmware can be installed easily
my suggestion is to put an option on website to modify hankou firmware instead of wuhan
