Did you try to reset memory?

Could be a broken welding also. In that case you might want to randomly iron all the places where you see welding.

First I want to update/downgrade(?) the ROM to the highest stable version, maybe that is will be help, but my problem is that, the calculator is continously fails, going to reset or simply not responses to keystrokes, therefore I cannot go to the Diagnostic mode and after that to the Terminal mode.

I want to try this: P0ERASE 1.0, but it is looks like impossible currently. I cannot to check the ROM version also...
