I have a SanDisk 2TB SSD which I had partitioned with GUID PT in roughly (as I remember) 1. NTFS: 250GB 2. APFS: 1TB 3. exFAT: 750GB While connected to an android device I was trying to format only the exFAT partition, but it erased the entire disk.
Disk: /dev/disk4	geometry: 243197/255/63 [3906963617 sectors]
Signature: 0xAA55
         Starting       Ending

sudo gpt -r show /dev/disk4

` I am assuming that all my data would be recoverable if I am able to recreate the original partition table?? I am trying the Testdisk tool but it is not showing me the APFS and exFAT... currently on deep search it shows the following:
: Unusual media descriptor (0xf0!=0xf8)
Warning: number of heads/cylinder mismatches 16 (FAT) != 1 (HD)
Warning: number of sectors per track mismatches 32 (FAT) != 1 (HD)

  HPFS - NTFS                 2060 3906963595 3906961536
I am not an advanced user but I am willing to try manual means to recreate the partiion table with experts' guidance here. Let me know what I additionally need to share here 🙏🏽. I am primarily on a mac device
