Bench Setup not working with NBT Evo

[Tuerkay]

it's fine.
put it on the car and all the text will appear!

not that easy. It´s not just missing text like it normaly happens on bench flash. It´s a black screen (not CP or wrong CID coding), no input response and an error, that i thought should not appear on this unit.
Right now it looks like the seller gave me a modified unit, where the sticker with OEM number says one thing but the Hardware inside another. Seller possible mixed hardware from different HUs...
