Hi,
Well this is all about
--flash_mode
because some use four and others two wires access flash.Check this page https://github.com/espressif/esptool/wiki/SPI-Flash-Modes
and try to lower the --flash_freq to 40m
Try the 4MB file.

Wow, what a unfriendly clone!
Do you another untouched board? If yes connect via serial and press reset to figure out how it was flashed.
?nd boot version : 1.? SPI Speed : ? SPI Mode : ? SPI Flash Size & Map: ? jump to run user1 @ 1000
Use this information to tame it .
Start with erase_flash and than with write_flash.

The following makes it work
esptool.py --port /dev/tty.wchusbserialfd12240 write_flash -fs 4MB-c1 -fm dio 0x0 espruino_2v04_esp8266_4mb_combined_4096.bin
As I suspected in the http://forum.espruino.com/comments/15179132 it meant that the firmware was actually fine. Just connecting to it has to have the
XON/XOFF flow control
turned off. I did not even realize something like this was even added and turned on by-default.So the following allows me to connect:
espruino --config SERIAL_FLOW_CONTROL=false --no-ble -b 115200

Great job, thanks for sharing the solution!
Can you please share the link where you got those boards from.

It is still not usable completely...
I get less garbage with 80MHz SPI Speed. But the serial connection drops after a while for no apparent reason... It behaves similarly with 20MHz.
wifi.connect() makes it disconnect and not possible to connect anymore.
It almost looks like some kind of thermal watchdog resetting after a while. It is fairly warm when I touch it in just a few seconds of plugging in.

The Tasmota MQTT firmware works without any issues on the same board with the following flash command

Hi!
I wonder what should I do to fix this. I have got a few d1-mini clones with:
Connecting with
espruino --no-ble -b 115200
I get gibberish and similarly as http://forum.espruino.com/comments/14147154/ I cannot connect properly.Hinted from the linked thread I tried all of the FLASH_MODEs and tried to connect to freshly flashed boards at 75600 bauds only to get the outputs below. Changing flash_freq, unplugging or anything else has no effect from what can I say.
Anybody dealt with this?
Thanks!
