boot:0x1f indicates you have a lot of strapping pins held high. Disconnect any external devices and try again. Do not use pins 6-11.

In that case you may have hardware issue, because from logs, like @lbernstone said, you have 5 bootstrap pins high including GPIO2.
GPIO2 must also be either left unconnected/floating, or driven Low, in order to enter the serial bootloader.
