This is an earlier version of the T-Beam board, and due to changes in the design in subsequent iterations this board uses a specific firmware file different from the other T-Beam boards.
firmware-tbeam0.7-1.x.x.bin is the correct firmware. firmware-tbeam-1.x.x.bin is incompatible. For all other T-Beam boards firmware-tbeam-1.x.x.bin is the correct selection.
