Well, thanks to Gymbo, I did, at last have instructions which had the right words on them. On to the next step, the required firmware. There was a button labelled download Sailfish OS firmware. The link, somewhat to my surprise to me to the Jolla Shop. Wells, fair enough, I opted for the paid-up product on the basis it came with updates. I'm very keen on updates, since they do seem so necessary.. So, I seem to have bought the SailfishX OS, and I seem to have received a receipt that said that I seem to have paid for it. But, and it's a big but. From then on there was not a page, paragraph, sentence or word about how you actually obtained said firmware. No matter where I searched, and I got into some weird page setups, nothing led me to the Holy Grail. So I'm stuck again.
On updates. In real life, I was a Production Engineering Design Draughtsman, and in those days people tended to get upset, particularly the ones who paid you, if you produced something that didn't work, or didn't work well, first time and every time, forever. Producing drawings which had to be re-drawn or amended was a very definite no-no. Then Britain decided that it didn't want anything to do with this Engineering thing, and I moved into IT support. We were into CAD by this time and I had an aptitude for it. There I discovered that producing something that didn't work and wasn't going to work was the norm. It was encouraged. After all, you got paid for doing it, then you got paid again for fixing it, then you got paid yet again because the fix didn't work either. It was an eye opener. Some of the toolmaking companies, when I was still churning out drawings, told me it was grand. They could tender low, in the sure knowledge that they could hike the price for the amendments. They rather liked my work, but regretted having to put a proper price in for it, because it didn't need amendments.
