Not every usb-TTL adapter works with 1500000. I have tested three before i found an working adapter.
But i think your board isn't dead. The last image looks good.
1. Erase SPI or set the jumper.
2. Flash an new image to an working sd-card
But the main part is to get an working UART connection. Without it, it's hard to find the problem.
