MAZDA 6 2018 tricore GBEF-57k30b TC23X-16F - Mazda 6

[Lans]

Good day.
I checked the issue with the sensors - they were not changed, they were not damaged and, apparently, they are in order.
On the table, the block keeps throwing the same error: U3000:49-8B.

In addition, I saw traces of attempts that they tried to solder to the processor and found out that the client had already come to me with this error.
And there is no certainty whether the file that I read and attached here is the primary one.
Also, on the table, I managed to check the operation of the power driver: it gives 32.8v; consumes 0.18A. It seems that the cause is also not in the driver.
When overwriting files on it (checked it several times) - it reacts to all missing peripheral devices.
There are no visible damage or traces of poor-quality soldering or damage to the contacts.

Is it possible to try to fix and write another file to it?

You must find original data!

Unfortunately, the file I attached above is all there is.

Can it be possible to check the file that you have attached above in this post?
The client understands that he brought me the block already with this error and claims that the primary files have not been saved anywhere.
He asks to try to repair it, because he cannot find the same replacement unit.

By checking the third party file I would be able to rule out a problem in the data and understand if it is a hardware error.

Unfortunately, this method didn't fix the problem.
Thanks for your help.

I understood why it is impossible to simply replace the file.
Thank you.
