i purchase an rk3229 7.2.1 tvbox from alibiba .. i cant do anything with it.. .cant update supersu.. cant use a different launcher.. twrp cant mount any partitions.. nothing.. so after trying to explain all this to the very nice asian lady.. she sent me a security.zip to debug it and said i should speak to a developer..
can anyone tell me how to debug it using this zip file?
i can use the usual tools but would be grateful for any advice.
Best
Nick.
