Replaced connector board still no disk mode

Unfortunately my original Op-1 has been bricked for a while. I’ve read a few posts over the past year about “missing content folder” and how difficult it is to get your op1 firmware reinstalled in this particular scenario. I replaced the connector board with a brand new one from ifixit but my poor op1 persists in not mounting as a drive. It charges via usb. I have tried one other Insignia Sync cable to no avail. As well as an older MacBook with an OS that the op1 always was able to mount to. I suppose it could be the dsp board but I have no idea how that would have malfunctioned overnight. Everything was as per usual up until reformatting the drive and ever since she is a $1000 paper weight :frowning:
