From some older Lenovo system with TXE firmware. It worked for a-dead-trousers (similar?) system but it doesn't mean anything for other models. Don't get your hopes up, this is for specific cases.

The cleaned/updated SPI image (outimage.bin) is proper, you did everything correctly. So either something went wrong during flashing or there's some security measure in place. Since Intel BootGuard was not a thing at Bay Trail systems, I don't think it could be something else. Did the flashing complete properly?

Have you tried removing all power from the machine (AC + Battery) for a few minutes (press the power button a few times while the system is off)? If that does not help, try removing and re-inserting the memory modules (make sure you put them back correctly) in case the problem is bad BIOS cache.

It's a shame that the machine no longer boots. No matter what, I wish you a Merry Christmas and happy new year as well a-dead-trousers. Personally I don't believe that your original though to update it was misguided but I suppose you're unlucky and stumbled upon some sort of Lenovo security measure or flashing mishap. For now you should definitely enjoy the holidays but if you manage to resolve the issue and possibly figure out what went wrong, please let us know so that the same thing won't hopefully happen to other people in the future.

Thank you for your kind words. I don't think there is a point in doing that for multiple reasons. No matter what, I would expect people to at least have a source link to the original forum thread.
