Kingston 4GB MMCmobile
 

Yesterday I was reading p900's thread about memory card capacity; fanoush mentioned that the 770 would support cards up to 4GB, but as we all know these are only available in MMCplus format and so won't allow the 770's memory card door to be closed when inserted into the device :mad:

Anyway, I contacted sales support at Kingston Technology to ask whether they had any plans in the pipeline to introduce higher capacity MMCmobile cards, this morning I received a reply...NO! In fact Kingston's exact words were:

Well at least they said "currently", but it doesn't sound too good, hopefully Transcend will come good. Also apologies to anyone spotting this thread and thinking that a 4GB release was on the cards!

I think they fear that there is no market for it. And they may be even right :-) Nokia and others moved to miniSD/microSD.

I am thinking about hacking miniSDHC card into N770. It should be possible. My idea is to stick/solder miniSD to SD adapter (that comes with each miniSD card) permanently on top of current mmc slot and cut a slot hole for the card in the black plastic on the right side when display is up (i.e. not on the bottom) and let the mmc slot otherwise untouched. One could either insert normal mmcmobile card via original doors or remove it and insert miniSD into the adapter from the right side. Both cannot work at the same time but it is not a problem with 4 or 8 gb miniSD cards. I have not opened my 770 yet but from outside it looks like the adapter should fit in.

That's not a bad idea, a little tricky maybe but certainly not bad :)

I take it you've spent some time looking over the schematics, as you say the fact that you couldn't use both the MMCmobile and the miniSD at the same time wouldn't matter if you're looking at using 4-8GB miniSDHC cards; the ability to use MMCmobile would almost become redundant since you're doubling the device's capacity at the very least!

Do you have any idea as to when you'll start dissecting your 770?

Re: Kingston 4GB MMCmobile
 

Isn't there room to just yank out the RS-MMC slot and simply replace it with the miniSD adapter? It would make cutting up the 770's body redundant.

Re: Kingston 4GB MMCmobile
 

Not today or tomorrow :-) I haven't decided to buy the miniSD card yet and also there is some possibility I might get dead N770 from some board member here so I'll probably wait until I get it (to have spare black case and to make trial run on killing the mmc slot :-) Also I currently don't have pressing need for 4GB yet. Still I'd like to do this mod just for the sake of doing it so I'll eventually do it anyway but not now.

Actually I will open my device soon and try empty adapter to see how it will fit but I won't cut/solder anything yet.

Re: Kingston 4GB MMCmobile
 

This may be a plan B :-) I'd prefer to not to kill existing slot. Cutting plastic body seems like less harm than killing the slot to me.

Maybe for this plan using microSD to miniSD adapter would be easier. But currently microSD cards with >=4GB capacity are not that common.

Re: Kingston 4GB MMCmobile
 

How about plan C: A full-blown SD slot? I seem to remember a thread where someone wanted to add an internal SD slot to the 770. That would suggest that there might be enough room in there for such a slot (although if that's true, I can't imagine why Nokia didn't do that to begin with).

Re: Kingston 4GB MMCmobile
 

Actually if you could do it by August of next year that would be really helpful as I'm off to the US which unfortunately means sitting on a plane for 10 hours :p So the extra 2GBs would come in handy for extra media to keep me entertained. Then again I suppose I could just buy another 2GB card, but that wouldn't be as much fun, for the time being I think I might attempt to remove the memory card door and use a 4GB Transcend MMCplus.

Re: Kingston 4GB MMCmobile
 

You need patched kernel for that. Once you remove the card, Nokia kernel waits with card detection until the door is closed. I already mentioned it somewhere here, it is just commenting out one line. I am not sure any kernel from me has this enabled but let me know if you want such kernel. With this patch card is detected by kernel when inserted but you still need to mount it by hand since the automatic card mounting feature waits for the 'door closed' event.

Ahem. [Sticking out card] + [no automatic mount/umount] == {big doodoo waiting for happen}

No?
