I attempt an OTA firmware update and it failed on 'fail' version number.
Reflash firware over cable will not work, web-page is not comming up
Was running ESP_Easy_v2.0-20180202_normal_ESP8266.bin
Reflashed several different firmware versions but no web-page comming up.
How can I make the sonoff basic work again

Are you attempting to flash a dout build?
Are you flashing the intermediate image first?
You cannot flash a new firmware directly due to its size. You need the megaOTAUploader to do it.
You will likely have to flash directly using the serial interface.

I flash with a serial cable (FTDI) from a linux laptop

Grovkillen is it like this:
From OTA I select ESPEasyUploaderMega_1024 followed by selecting the latest version of espeasy?
I did the following to solve this issue:
erase flash with command:
sudo python esptool.py --port /dev/ttyUSB0 --baud 115200 erase_flash
and flashed ESP_Easy_v2.0-20180321_normal_ESP8266_1024.bin with command:
sudo python esptool.py -b 115200 --port /dev/ttyUSB0 write_flash 0x0000 ESP_Easy_v2.0-20180321_normal_ESP8266_1024.bin
now everything is working again
