Could a T10 become a 4 or 8 gig unit?

[Sesquash]

I was just thinking today that the firmware that runs a 1 gig and 2 gig T10 is the same, and perhaps the same firmware that runs the T30 and T60---so that leads to wondering, ....if one were to de-solder the 2 gig flash memory chip on the black body T10, and replace it with a 4 or 8 gig flash memory chip....(if that were physically possible ((number of pins on each chip must match for placement back onto the T10 motherboard)) would the T10 v1.77 firmware be able to address 4 or 8 gigs of memory?

I think that I will attempt to source out a flash memory chip at the 4 and 8 gig level, and see if it can physically be accepted by the T10 black body motherboard. This will take a little time as I don't think iRiver will make readily available, service schematics of the motherboard specifications and chip placements.

If anybody has already taken apart their T10 2 GB unit and has noticed if there is a manufacturer's name or stamp on the 2 GB flash memory---and could publish that name on this thread, that would be most helpful. If there is--- and it just might be Hitachi--I/you could start there with matching the same manufacturer, but with a higher capacity chip.

I can't see why you would not be able to update/modify the capacity of the T10 IF...you could find a suitable FLASH MEMORY CHIP for the task. A tech shop could then de-solder the current one and solder back in the higher capacity no problem. I wouldn't attempt that myself.

Just a thought to throw out there. How cool would it be to have a 4 or 8 gig T10!

I have just purchased a bricked 2G T10 off ebay, hope to repair it when I have enough time.

This is the 2G flash chip:
SAMSUNG 604
K9HAG08U1M
PCB0
CCL54620

I managed to find a datasheet for this chip, with pin configuration, some commands, etc.

Don't forget that T10 uses FAT 16 as filesystem, which cannot work with partitions larger than 4 gb (I think)

Good go! Could you possibly tell me what the pin count is for this chip?

Thanks for your info!

I had an old RCA Lyra player that I could reformat to FAT 32 via Windows. Its native was FAT 16.

With more adress lines in a new chip, it may be larger in pincount than the older one unless it have reserved pins. Also T50 may not have sufficient ram capacity to hold a huge 4 gb's FAT. I think it is completely transferred to ram when it first powered on and again with any modifying in filesystem. That is what I understand from t50 that displays "scanning files" for a long time.

It sounds like a good idea, would be nice to fit a few more songs on my T10
