  • Flash type : eMCP BGA221
  • Flash chip name: 5PA98 JY941
  • ID : 2c 44 44 4b
  • Flash chips amount : 1
  • Dumps amount : 2 (chip got two seperate channels)
  • Totall size: 8 Gb
  • Controller: looks like PS family..... (???)
  • Page: 8790
  • Block: 256p
  • Sector:1034_70/(1028_70)*7
  • System: FAT32


No layout found



NOTES:
This are donor drive with 8Gb of JPGes, can you look to this to create model ? If you need can create LBA or Pattern. We got exactly same case to solve but there are some cells with life span exceed and many bit errros so I think better will be to make model for fully working and new IC. Chip readed with other reader but with same config as FE

Dumps uploading....

UPDATE:
I readed ONFI parametrs from chip and they are diffrent from used in FE (blocks amount)

ONFI:
Model: MICRON MT29F32G08CBCDBH1
Data bytes per page: 0x2000
Spare bytes per spare: 0x2E8
Pages per block: 0x100
Block per logical unit: 0x850

Do you want to connect to adjust config ?

Results on donor and client chip are 100% after additional correction with correct RR parametr and connection trick. Once done image are 100% green and got all data including logical structure exFAT on client IC

Thank you

P.S
Checked this model on 5RA92 - works too
