I just received some new ESP-07 modules and I have the problem, that I can't flash them.
If I set to bootloader mode this is the output (baud 77400):
ets Jan 8 2013,rst cause:2, boot mode:(1,6)
If I reset the module without bootloader mode:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

But if I use the UNOFFICIAL DEVELOPMENT KIT FOR ESPRESSIF ESP8266 I can't flash the device.
I have no idea why not. Another ESP-07 module was working with the same hardware config.
