It is very strange why this command broke your GPT. Actually incorrect PMBR can prevent probes for GEOM_PART_GPT. >> I don't have such a backup, only the whole disk for now.

After that you should add all partitions with exactly same offsets and sizes. In this case your data will not be touched. -- WBR, Andrey V. Elsukov
