I made a mistake and bought a Ledger Nano S from a reseller and decided to take it apart to check the hardware integrity. I compared it to the information they provided on the official site and everything seemed ok. But next time I connected it to my computer there was no display. When I reopened it I saw that the flex display cable was partially ripped. I thought I was gentle with it but looks like I wasn't. Is it possible to fix this kind of defect or will I have to buy a new one from the official site?
Oh man, I'm very sorry for what has happened with your new Ledger Nano S. As a matter of fact when opening its case it's very easy to damage that flexible cable if you were not knowing the correct disassembling procedure . When I was opening mine I have followed
this video instruction and everything went smoothly. As others have already said the best way for now is to buy the new device from official reseller.
