As I mentioned, I checked and all files are the same, and also it's the same after recompiling from source. Try downloading again from the links in this post and from sourceforge and make sure the files are identical. I don't see any reason for the ROM to fail, the binary looks fine when I looked with a hex editor.

I finally found some time to come back to this topic. I am obviously misunderstanding something. To me, it seems that the file from sourceforge, named newRPL-1255-firmware-40gs.bin, and the file from this thread, found at https://hpgcc3.org/downloads/newrpl40.bin are not the same. They are not even the same size. The former is 1044420 bytes long and the latter, 1044356 bytes.

This said, after changing the USB cable and starting anew with fresh batteries, I was able to flash the calculator successfully. I tried to reproduce the issue I observed, but could not. I would recommend making sure that the batteries are fully charged before updating, but I am not sure this was the problem.

I know it has been mentioned before, but on some machines, and at least on my HP 40gs, newRPL is initially setup with the LCD so light that text is almost completely invisible. I remembered that, so after the update, facing a blank screen, I pressed ON + to make the screen darker. This did not succeed, because newRPL was asking for a confirmation, and contrast control was not yet available: I had to press F1 first (but did not see it at first because the screen was so light). So I would suggest making the initial LCD contrast setting much darker, so that anybody can see that there is something on the screen.
