How to readd a missing partition on the phone?

[swedishsailfishosuser]

I accidentally erased 1 or 2 important partitions so now when I want to flash anything other than the stock ROM or Lineage OS it fails due to the missing partition/s.

I have root access.

Hi swedishsailfishosuser,

Welcome to the community. 

Try giving Sony Mobile a call about this. 

Thanks,
