Problem reflashing SONOFF with ESP Easy

[Chano]

Hi, I bougth one SONFF device to start testing the ESP devices (it's so cheap, that it's not worth build one by myself!)

I made a mistake using a 5V FTDI adapter instead of a 3.3V adapter, but it worked perfectly. The problem is that I must have blown something because, even it is working, the power regulator gets extremely hot (it have even melted the SonOff case!) so I consider this device lost. Providing it was working, I've ordered 3 new devices and a 3.3V FTDI adapter. But when I try to flash the firmware, if I reflash the first SonOff I bought (the one that heats up), it works, but with the other 3, it doen't work and this is the output of the flash tool.

omport (example 3, 4, ..) :5

¿Any one can help me how to solve this?

Thx in advance

Flash size should be 1024
