How exactly this can be done? There must be some NAND flash memory somewhere. It is possible to reprogram flash memory using good old LPT port from the PC? I can make some stuff with ATMEGA controller btw
Look

Our reckless team have dumped both SPI flash and eMMC from 55J5500. Here are some pieces (a full dump is too big, 4GB)
Any tips, guides?

buy emmc programmer like rt809H (not recommended) or UFPI and ISP adapter and you can (not easily but possible ) dumped and restored samsung firmwares from latest tv ,and possible firmware downgrade (with hdcp and ci+ key loss easily and with restore keys not easily )
