SM3257EN USB Flash drive work

I'm looking for someone who knows the SM3257EN controller and how to setup a flash drive with it. It's a custom PCB with a K9gag08u0e NAND flash onboard. The device enumerates alright but does not show up as a block device. I have been able to open with the SMI Mass QC Tool https://www.usbdev.ru/files/smi/smimptool/

I need to know the correct programming configuration for this chip and flash controller. I am willing to pay for anyone that has experience with this chip.
