so if we compare that re-encoded unber with the original one, we see that there is the following bit in the original (just after the SYSMOOCOM-TEST-1 string, which is not present in the re-encoded one:

Ok, so the reason is that the EUICCInfo2 (part of the euiccSigned1) in this example is actually a SGP.32 EUICCInfo2, which has been extended with additional fields compared to the SGP.22 one.

While in general those extensions are backwards-compatible, this "of course" breaks if we go through the decode -> re-encode path.

So it seems like we need a raw BER decoder (like 'unber') to extract the raw binary/DER-encoded euiccSigned1 instead of doing a re-encode.
