I was warned that one of the Lumias in the box is bricked. It immediately gets stuck in a boot loop when turned on. So, I counted it as dead. Yes, I tried some resurrection tricks, but nothing worked. I wanted to give up and just throw it away.
However, my colleague wanted to try it out. He succeeded using a very interesting method that he discovered by accident. He downloaded the same recovery/firmware flashing tool as me, but he downloaded the operating system for the phone from a different page. It appeared that the only OS that worked was the Russian ROM. He downloaded it because it was the only one he could find. And it worked. The phone booted on the first try without any problems. I am really happy it works, even though it is a Windows Phone.
As usual, I have installed enough games to fill all the available memory, and I am going to try them out.
I tried a Lara Croft-based endless runner, but it just displayed some cutscenes with a book and then crashed immediately after the gameplay should have started. I also took some stupid games from the WP Games Archive, but the titles I am really looking forward to trying are Jet Car Stunts, my favourite, and a Civilisation game, which I definitely must try.
