That’s good to hear! 
I’ve also tried reformatting the original SD card and flashing the official image, but no luck so far… I also checked the card with badblocks and did not find any corrupted blocks on the disk.
By the way, is it normal, that the two PCBs are not aligned in parallel but slightly tilted towards each other? It’s my first 2HP module, so I have no idea how things are supposed to look like…
