Flash0 chip (W25Q32), Flash1 chip (S34ML01G200) and SOC chip (BCM3390) all related, you can not change one except you can hack it. I upload the all firmware to:
https://mega.nz/file/GeYgTDbR#6S7UqnYRWg...FVmyTNE_Hg

BTW, the serial port in the SB8200 PCB already disabled by Linux system, I do not know how the factory re-work it if need to repair, maybe just change the whole board.

How can I change MAC address of SB8200 to match my current modem, so that I can swap modems without calling ISP customer support?
Is MAC stored in SPI flash or NAND flash or Broadcom CPU?
Did anyone figure out NAND ECC algorithm? Modem itself reports that it's BCH-4 and it looks like BCH-4, as I see 7 bytes in OOB for each 512 byte block. But I can't verify ECC. Neither of available algorithms available in Flashcat USB work.
Did anyone figure out how to extract filesystem? Binwalk can't find anything.
