how to repair this problem

and this
Caution: The CRC for the backup partition table is invalid. This table may
be corrupt. This program will automatically create a new backup partition
table when you save your partitions.
Problem: The main header's self-pointer doesn't point to itself. This problem
is being automatically corrected, but it may be a symptom of more serious
problems. Think carefully before saving changes with 'w' or using this disk.
Problem: main GPT header's first usable LBA pointer (9)
doesn'tmatch the backup GPT header's first usable LBA pointer (22)
Problem: main GPT header's last usable LBA pointer (747FF7)
doesn'tmatch the backup GPT header's last usable LBA pointer (747FDE)
The 'e' option on the experts' menu can probably fix this problem.
You should use the 'b' or 'd' option on the recovery & transformation menu to
select one or the other header.
Final checks complete. Writing a new GPT data...
Successfully written a new GPT table to eMMC.
The operation has completed successfully.
Caution: invalid main GPT header, but valid a backup header!

Write errors - you eMMC may be dead, try to change it

[debeliamark]

Atleast there no need to use eMMC tools to revive S7-721u - can be handled via Qualcomm 9008 , but ... in most cases - 3 from 4 - if normal standard SD update do not rework Software related problems - probably eMMC is dead. So - change it and repeat operation. For sure you can use eMMC from tablet with broken screen or put a brand new inside
