READING IN ON TANGO same thing, Read Only

Few months ago when the first YS-01 was released I was able to right 4c on them, but now there is no YS-01 like the one before that can write 4C and 4D at the same time. 

There is now YS-01 for 4D that you can copy 4D using any tool. 

And there is YS-01 for 4C that can be used only for CN900 and can’t be used on other tools (as far as I have tested them)

Besides, the tm100 is getting updated all the time
