FX3 boot mode

Having no changes to the bladeRF micro's hardware, does the fx boots from spi flash?
Supposing that the spi flash populated with some custom firmware earlier, and for now, the board is not recognizable by a PC using lsusb, how can I recover it?

I flashed the spi flash with the latest firmware using flashrom and test clip, but the board is still not recognizable by the lsusb and dmesg.
The logical analyzer shows no interaction between the PC and the board on D+, D- channels. The logical analyzer also shows no signals on MISO channel

Nothing at all that can point to a board
