Changing chip on N900 N9 or N950? (like upgrading the N950 to 64GB or upgrading ram on N900)
 

I was thinking, is it possible to change the capacity chip from the N9 to change a 16GB device into a 64GB by soldering it?

I don't know if the N950 uses the same chip as the N9, but if so, would it be possible to change N950 capacity chip with a N9 64GB chip?

Re: Changing chips on N9 or N950?
 

From the early N950 (N9-00 Dali) prototype, there seems exist 64G N950 models, I guess they use the same memory chip with N9. So maybe it is possible.
Also this makes a red or blue N9 64GB possible...

A bit risky though... :)

Re: Changing capacity chip on N9 or N950?
 

I've got a soldering iron and I'm pretty handy with it. Do you think I could do this?

Re: Changing capacity chip on N9 or N950?
 

Those chips are actually need to heat up to get removed afaik... This operation requires really talented people...

I know a couple guys who can do the job. I only need to know if they all use the same size/type chip. Maybe we can find and buy those from somewhere?

Re: Changing capacity chip on N9 or N950?
 

no. soldering chips with a "single-tip" iron is like driving 220 on a curvy landroad, chances it goes wrong are very high.

The production involves heating up the whole circuit board including preplaced SMD. Exchange of single components afterwards has never been kept in mind during construction.

The very least you need to have, is a special chip-tip that heats up all pins simultaneusly.

Re: Changing capacity chip on N9 or N950?
 

not quite, at least not without good lab and good tools...

Re: Changing capacity chip on N9 or N950?
 

Changing /any/ SMD chip has already been discussed since N900 days, especially the eMMC and SoC.

tl;dr version of every single discussion on this already:

It's possible, but incredibly impractical to do so unless
a) You can obtain a single part for cheaps, and
b) You have access to $$$$$$ tools to properly do the swap.

You'd probably have to be a very bored EE to do this instead of buy something else.

Re: Changing capacity chip on N9 or N950?
 

I have access to those $$€€ tools :p

The only thing I need to know is just the name of the part and try to find it (doesn't matter if cheap or not)
If we find it, I think many people will be happy to mod their N950's to gain more capacity... (I'm sure there are local repair guys who can change those chips for a few bucks :) )

Re: Changing chips on N9 or N950?
 

The better option to make this possible, is to buy a Black 64GB, and perform a housing swap. Many people have done it (including myself, twice) and it is safer then messing with chips

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

Does anybody know which one is the right chip to replace on the N950?

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

not that hard to detect, like if you look what 64gb chip look like...

http://st.gsmarena.com/vv/newsimg/12...marena_001.jpg

Well anyways even if you know what chip to replace, your changes to change to bigger one and have running device afterwards, is near 0%, even if you manage to change it successfully... especially if you don't have access to factory flashers...

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

What about if we swap it from the N9 64GB?

Re: Changing chips on N9 or N950?
 

I'm planning to buy a white 64GB N9 next week when I get back to Shanghai.:D

But for N950 that's the only method to extend memory.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

So is the big Samsung chip on N950 the memory? Looks possibe to change...

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

I eagerly await the day when you destroy your N950.

So this should be it....

Edit: seems like the PKG and the PKG Dimensions are different... Would that work out? :(

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

There is always someone needs to be the first to try.

If you don't have any advice, just shut up!!

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

I'm very interested in outcome of that - especially, that if HtheB really have access to required $$$ tools, it would be possible to change N900's OneNAND to one containing 1GB RAM (quite hard to get exactly same type with more RAM, but still possible)

We all know what it means, and where harmattan can hide, then ;)

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

I'm betting on no. You'd need at the very least, for the package (type and number of solder joints to board) and the package dimensions to match up, unless you want to carry around an external board holding your chips ;)

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

The $$$ Tools can be more affordable than someone can think.
For example search info/videos about Tornado Soldering Station V2

The main problems are skill needed and spare parts.

For N900's nand is more difficult than eMMC because Nand (and Ram togheter) is a PoP chip.
But it remains theoretically feasible.

I have suggested it on : http://talk.maemo.org/showpost.php?p...&postcount=133

I know (by internet) a company specialized on replacing Omap Soc and their PoP chip on existing Arm Board.

The main problems are:

• How much money they want for doing the job ?
• Newer PoP chips (up to 2GB ram with up to 4GB Nand) are pin compatible with one used on N900 ?
• Newer PoP chips are available in small quantity ?
• Omap 3430 used on N900 has max values for ram and Nand supported ?
  And what are these values ?

Furthermore in this thread we are OT :D

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

The safest option will be using the eMMC chip from a 64GB N9...

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

I can sell a cheap N9 64 for testing, it is so beated up and the digitizer doesnt work. $270 USD + shipping

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

and can be negotiated

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

If you point me to the right direction where the chip is located at, and where to find one, I can try to swap it :)

so this is a no go for the N950? :(

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

On N900 ?

On N900 but I think it is the same on N9/N950 too, ram chip is a PoP chip, so it is soldered on top of cpu like a sandwich.

OneNand (on N900) is in the same chip which contains ram.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

Seems changing eMMC is completely possible:p I just googled it seems a lot of andriod users are doing it.

What I need is the correct chip, I'm thinking buying a second hand black 64G N9 for the safest chip.

And I'm wondering if I can find expert to do the N950 resemble as it's much more complicated than N9, and of course swapping the chip.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

yes, but you need to be sure that the pins under the chip are the same... I will look how the pins looks like on the N950.

I'm taking this risk for all N950 users out there....

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

do it for n900's RAM (for 1GB) as first priority, and You will reach Maemo Community's valhalla, in one big step.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

Show me a picture which chip it is, and which chip I need to put on (like which brand etc) and I'll do it :)

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

If you accomplish it, I will be your first customer :D

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

For sake of completeness (HtheB heard it already on IRC):
http://maemo.cloud-7.de/Gallery-N900...d/n900_01.jpeg

Thing with "Samsung" on it is OneNAND. OMAP (CPU etc.) is under it, between OneNAND and PCB. On the other side of N900, we have chip with "toshiba" on it - it's 32 GB eMMC.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

In other words: If I replace OneNAND with an 1GB one, I'll be done, right?

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

You'll still need to recreate partition structure on OneNAND, from mtd0 to mtd5.

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

The chip is 256MB OneNand plus 256MB DDR ram.

The chip is a Samsung but I suppose that one of these Micron chips is similar if not the same:
152 pin: http://media.digikey.com/pdf/Data%20...C%20Family.pdf
168 pin: http://www.google.it/url?sa=t&rct=j&...NPkIZA&cad=rja

He wants 1024MB ram (supposing Omap 3430 can support it), so you need a chip with 1024MB DDR and at least 256MB OneNand (but bigger is better).

I know a company (Microsemi) which produces PoP chip for Omap with 1G ram + 2G flash or 2G ram + 4G flash.

But I don't know if these models are compatible with Omap 3430

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

Got us a link? maybe this could lead us to the right direction

Re: Changing capacity chip on N9 or N950? (Upgrading the N950 to 64GB)
 

One month ago I have found something but I don't remember the direct link and now I have no time to do deep search on internet.

Furthermore it isn't clear if microsemi speaks about gigabyte or about gigabit.
A 4G-2G chip should be only 512MB flash and 256MB ram if values are gigabit.

The chip is Microsemi's MS29C2G24MAKLA1-XI

Re: Changing chip on N900 N9 or N950? (like upgrading the N950 to 64GB or upgrading ram on N900)
 

Definitely 256MB RAM and 512MB Flash, unfortunately.

Of course, Hurrian's point about recreating partition structure is absolutely valid - I forget about it (but it isn't roadblocker, AFAIUI?)

Re: Changing chip on N900 N9 or N950? (like upgrading the N950 to 64GB or upgrading ram on N900)
 

I read in Russian forum it is possible to change capacity even to 32GB:
http://forum.allnokia.ru/viewtopic.p...566&start=2715

User root_user had changed hynix H26M52002CKR to Toshiba THGBM1G8D8EBA12 .

Re: Changing chip on N900 N9 or N950? (like upgrading the N950 to 64GB or upgrading ram on N900)
 

Let those guys join the official forums, and share their thoughts about this! :)

What about the N950 eMMC?

Re: Changing chip on N900 N9 or N950? (like upgrading the N950 to 64GB or upgrading ram on N900)
 

hello,

I never look posts at n9/n950 forums, a shame.

it is very interesting what has done that guy from russia but as I see the 32gb is from an n97 and he says that his n9 is slower.

Do you think it is possible to upgrade our eMMC?
