Help to interchange diferent uefi bios on same hardware of Intel Tablet

[marioneta]

I have 2 Intel Education Tablets from 2015, it seems that they are identical but with diferent bios version. I have copied the Dump from the first tablet an programmed to the second tablet, the ME region is already cleared but the machine doesn´t have Video. Comparing both Dumps are a little diference in size but they are only a few bits at the end.
Is there a way to make it work?

but the machine doesn´t have Video.

Because these dumps are not complete. There must be one additonal SPI BIOS chip on boards.
When you programmed the dump to the second tablet, the parts of two different BIOS versions could not work together.

I also encountered a similar error. I tried but it still gives the error.
