W5 No display

[Mayelo]

Hello: Yesterday I try to unlock this phone using motorocker 2.22 and ex tp cable,, first of all not sucess because software show ´´ bootcore not supported´´,, well assemble the phone and do restore, later turn on but the image is not showed in the internal screen only in the screen of oustide..

I do replacement of display and flex but the trouble persist...maybe the damage was done in the motherboard with the neddle of tp..

My question is how to repair this failure?

Thank you by your attention..
