Starting again the process, testdisk say to me that both partitions are irretrievable...

Should I give up on testing? Can I try something different from what has already been tried?

I confess that I am desperate and I didn't expect to lose this data.

I ran testdisk and after some time scanning, it found some information, but when I tried to access it, it was not possible...

Finally, it suggested the test below, but I am not able to run it correctly.

Try any other commercial recovery software that supports ext4. If that fails, use PhotoRec.
