It seems a difficult scenario but you may take the Intel® SSD to a data recovery service. There are some Intel® Partners that provide this type of service without affecting the warranty of the drive.
For warranty replacements please contact your nearest Intel® support team.
I am truly sorry for the inconvenience.

The 8MB state is a general drive failure state. Additional information on the type of failure is contained in the Bad_CTX 0000013x information: https://communities.intel.com/thread/24205
Some types of failures that result in the drive showing 8MB allow the drive to be restored to functionality via Secure Erase, but in all cases the logical data mapping structure is damaged and the data is likely to be unrecoverable.
