Toshiba SLC 2048/128 junk data

[twisted89]

I'm attempting to read the following nand but I seem to mostly get junk data with no sign of a file system or bootloader.

I'm not sure if the nand is faulty or there's an issue with reading so any help would be appreciated.

I had to make some manual changes to the code to support the nand as ONFI is not supported and the OOBSIZE was wrongly calculated as 64 instead of 128.

With those changes I get this

From the information I can gather the bad block check is at 0x00 in page 0 or page 1 of a block so
page_data[self.PageSize] != 0xff:

which results in a massive amount of bad blocks. Also, reading in non-seq mode is the only way to get data, with seq mode enabled only 00's are returned.
