- Sun Dec 07, 2014 4:19 pm #4219 XTCOM crashed halfway through update on my Win8-64 machine and I thought my ESP-01 was bricked forever.

So, what I've used and that worked very well for me is the ESP8266_flasher_V00180902_03.zip tool from https://drive.google.com/folderview?id= ... ptbzg#list.
It's all in chinese but cut&paste to Google translate helps getting around. It has the V0.18 AT and v0.9.2 firmware builtin, but you can replace the files by 0.20+0.9.3 too.

Using this you get a progress bar and log messages while flashing.

I could recover my damaged ESP-01, back to v0.9.2/ATv0.18 F/W, and then flash v0.9.3/ATv0.20 from espressif.

Beware that it seems that 0.9.3 boots at 115200 and no more 9600bps on the serial, so this may be a problem with software serial.
