Ive been looking and I have seen a way to upgrade the bootloader via rockbox but if I'm wrong please let me know. I was reviewing the ata nand controller the SST/SST55LD019C SST/SST55LD019a SST/SST55LD019b and SST/SST55LD019M. the c and m both support 32gb so I assume the SST/SST55LD019K also can also support at least that much. So apparently 2 128gb chips may have been ambitious but it says it can support 8 chips? weird, does that mean 8 32gb or 8 smaller capacity. The daughter board ipods are pretty finnicky, when I take off the daughter board to upgrade the chip solder chips on (even if they are the exact same chips I took of) it tells me to restore the ipod and no matter how much I mess with it I just keep getting busy signal. Eventually after messing with them enough and leaving them on charge for a couple days I can sometimes get them to restore with the original chips. So I will no longer use daughter board ipods. only problem is I only have 1 k9hag08u1m that was from one of the non working ipods, it appears to have a few bad blocks 25 to be exact lmao. I guess I'll have to buy some chips 32gb or smaller and see how they work. I message SST for a data sheet for the SST/SST55LD019K but ill have to call them on monday and see if they still have one (doubt it lol). also theres a good chance the k isnt a thing and its just a special chip they did for apple so nobody could figure out what it was. I wonder if my programmer can support it so I can figure it out I dont have an adapter for it tho haha.
