Got d1-mini clones and not able to flash them

Hi!

I wonder what should I do to fix this. I have got a few d1-mini clones with:

Manufacturer: 20
Device: 4016
Detected flash size: 4MB

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!
