How to reflash SDK 1.4.1 onto my EPS8266-01

[PicoPi]

Hi,
I wrote over the flash with my Arduino IDE when I was messing around.
The good news is I can now upload my programs using the Arduino IDE.
The bad news is, I can't reprogram the module to how it was and can't use AT command.
I tried for 2 days to be able to do this.
How the hell does one do this? It seems it should be straight forward, but it's anything but!
Help!

Yes. I managed to reprogram the module with 1.52 after 4 days of struggling. I an Engineer with over 30 years of experience. If I am having problems with such a simple task, imagine what the newbies are going through.
The documentation is very hard to understand. You might want to consider hiring a technical writer (fluent in English) to do this job.
It's not like you are not making money hand over fist!
The old saying: "A product is as good as it's documentation" still relevant.
Thank you.
