I see. To be honest I hoped that it wouldn’t come to this, especially because I hate connecting all 12x SMA->U.FL pigtails inside Luftek’s enclosure, this is really challenging for me because of the size 
But I guess you are right and replacement is the only reasonable way to go.
One more question though - both of my boards were HF modified by Lime, and I know that it was done only for some boards and now it is not possible to order new board with such modification. So may I hope for it to be done also in this special case of board replacement due some malfunction?
