I've had a couple of esp07 boards get "stuck" in programming mode.

I've got a button with an led hooked up so that I can pull the pin low to enter programming mode (though the arduino port) and see that it has restarted in programming mode by the led staying lit.

I've had 2 boards get "stuck" in programming mode while being programmed now. No matter how the boot pins are configured they will stay seemingly in the program mode after every reset, I also can't seem to program them again. (ive removed the esp07 from the pcb its on and popped it into my testing jig so I can be sure that the boot pins are being correctly set, swap out the "stuck" esp07 for another and the jig works fine for programming)The last time it happened I was trying to program at 460800 rather than 115200, not sure if that was the case the previous time too.

Is this a known issue? Anything I can try to do to save my esp07 from the bin and bring it back to life? (I've tried using esptool to connect and erase the flash without any luck with it connecting to the chip)

How do you wired the LED and on which GPIO (in Sink or Source mode ?) ?
What about the other wiring (RES/CH_PD/GPIO15/GPIO2/GPIO0) ?

You probably should try to add a 10K resistor in parallel to the LED, so that GPIO0 is really pulled-up.
