  Core v5: Split by dump, Parts 4, Save dumps as:
  01_01-> 01_01 + 01_02 + 01_03 + 01_04
  01_02-> 02_01 + 02_02 + 02_03 + 02_04
  02_01-> 03_01 + 03_02 + 03_03 + 03_04
  02_02-> 04_01 + 04_02 + 04_03 + 04_04
  On each 16 new dumps use Split by block 0xd6e000, parts 2
  Each 32 new dumps save as 01_01.dump at separate folder with number 1...32 
  Put FE/chip.txt there
  This case use software bad bytes
  Use model on each folder
  SBB: auto ff + manual correction
  This flash use many different sectors size:
  32_1140, 32_1138, 32_1142, 32_1126
  So need use differen layout for different dirs 1...32
  Assembly and save each image at Join directory as:
  Dir 1 -> 01_01.dump
  Dir 2 -> 01_02.dump
  Dir 3 -> 01_03.dump
  Dir 4 -> 01_04.dump
  Dir 5 -> 01_05.dump
  Dir 6 -> 01_06.dump
  Dir 7 -> 01_07.dump
  Dir 8 -> 01_08.dump
  Dir 9 -> 02_01.dump
  Dir 10 -> 02_02.dump
  Dir 11 -> 02_03.dump
  Dir 12 -> 02_04.dump
  Dir 13 -> 02_05.dump
  and so on... till 04_08.dump
  Put there folder FE/chip.txt with page size 512 bytes
  Next step is save 8 parts after join. Use model:

    Raw
      Block Size  0x3000000
  And save as Disk1.image, Disk2.image...Disk8.image
  Last step is join by dump but images have different quantity of blocks
  There was HFS file system so problem with checkpoints to align shifts beetwen 
parts
  Disk1.image give good structure and data from this part
  To get rest of data need align shifts or extract data by scan method
  To correct ECC with different layouts you need use proper RAW cut step
  To solve this case you need ~6TB space on drive
