I have a good seller from aliexpress who sells them to me privately for 129 dollar (shippment to germany inclusive). He also sells the 2tb configuration for the m1 for 110 dollar. I can give you (and of course everyone else who needs) the contacts if you want.
Got a tip for us?

I finally got my A2338 M2 macbook working with 2tb instead of 256gb. In comparison with the M1 upgrade its really not as easy since adding all the small capacitors and resistors is a really long and hard way to go. But since you go from single nand to dual nand its actually worth it.
The most important thing is to first set up the nands and then start adding the resistors and capacitors, since they can easily get lost when adding the heat to remove the nand. With the schematics you can easily spot all the parts you need to add (just as dosdude said in his Video about the nand upgrade: everything with ssd_2l).
There are also 2 small capacitors on top of the m2 chip and 2 above the second nand. Also there is one resistor on the back of the m2 chip that has to be placed. The rest is just on the back site of the second nand.
I think the smartes way would be ordering all the capacitors and resistors from mouser or somewhere, so you can add brand new ones and dont need a donor board. I only had a M1 donor board and had to check everything twice since some parts are on different places.

Does anyone know if there is any important difference between the KICM223,KICM223R and KICM223K? I’d check the datasheet but they seem nonexistent!
They are all the same, and will work no issue. Just ensure they are properly programmed or blank, of course.
Balls of STEEL to attempt this. Respect.
Many thanks, it is great to remove an unknown. Also many thanks for your experiments and detailed videos.
Finally finished upgrading a 13” M2 MacBook Air after locating the correct chips! Got it up to 2TB by using 2x blank/new KIC5228 chips and adding the necessary missing passive components.

I became a proud owner of a 16gb 512gb M3 MBA yesterday. I have been watching SSD upgrade videos on YT, especially by you dosdude1, very inspiring! I want to do the upgrade on my M3 but am not able to find the exact nand chips on aliexpress. Are they the ones from iPhone 14 and above?
Yes, though you want to ensure they are new/blank, as ones programmed for iPhone 14 already will not work. For 2TB on M3 MacBook Air, you are looking for "K5A8" NANDs.
@dosdude1 can you tell looking at these pictures if I destroyed the solder pads on the motherboard?

Yeah, looks like most of the pads are ripped, so board is probably trash at this point. As I always say, with underfill removal especially, you need to practice a good number of times on some junk boards with underfilled chips to ensure you can cleanly remove them before attempting with a good board. It took me at least 4 or 5 tries before I got it down well enough to attempt on a good board my first time.
So since the board is trashed I thought why not try my hand at the second nand. I'm the kind of person that just can't accept failure and it will nag me until I do it right
. I think I had better luck with the second nand after calibrating my hot air station temps. I used my infra red thermometer to check the temperature of the air exit tube for a rough idea and at 350 degree setting the tube temp was 270! I jacked up the temp to 480 (max it allows me to go) with tube temp of 350. After that the second nand came off looking like this, the I had tried to pry it before jacking up the temp as evidenced by the two damaged pads on the bottom right. I could not get any glue when I tried to scrape it off, not sure if it came off with the chip or melted???Attachments
Lol luckily this is just a hobby and my livelihood doesn't depend on it... I'll chalk up the $640 spent on a learning exercise. Incidentally I bought an M3 MacBook 16gb/512gb for $1080 last week for tinkering with asahi on it once it is ready for M3. All in the name of learning pursuit
my personal daily driver is a Linux machine and work is a locked down m1 pro 13.So I do have the two unused 1tb kicm223 nands I got from aliexpress if anyone is interested in buying from me.
Do you still sometimes make mistakes or after learning it the success rate is 100%?
Nope, never had a single failure after completing my first successfully. Once you practice and get familiar with the temperatures and force needed to remove the underfill, you can get it done without issue every time.
Shame that its not complicated for a trained person to do ... because it means Apple Genius Bar could do it too. Instead buyers have to make up their minds about capacity before purchasing. Apple at least should allow a mother board exchange program, with increased capacity to suit a previous buyers needs. It's not a customer focused business model, while the competition does mostly allow user upgrades.
Where you being satirical?
Doubt this a sit & wait while this is done type of procedure. @dosdude1 if your experience how long does it take to do an SSD update (once you are experienced at it)?
I'm in Australia.
Apple does take and repair their gear. An example are the faulty MacBook Pro keyboards. They'll replace motherboards and screens.
Apple's business model was always for very high parts costs. Their fear was people buying Apple parts - say a motherboard - and putting the motherboard into their own computer casing. So Apple always sold their parts for very high prices. But they'd trade in a motherboard for a high price. Which mean't a broken Apple computer could have its faulty part replaced for a reasonable price.
It would be possible for Apple to swap over a motherboard via their service capabilities. And because their SSD prices are three times what they should be, they darn well should offer that service. They should simply have a minor service charge, and the price of changing from 1 TB to 4 TB, should be the same as when paying for that extra capacity at the time of buying. That process would make up for Apple not having upgradable SSDs. It would also increase the used value of a Mac. The same model for RAM should also be available.
If a brand gains a reputation for not being customer focused, it can damage the whole brand and hence hurt the whole business.

It depends on the machine, but if it is dual-NAND with both NANDs populated already, it takes about an hour or so to do the swap (not including the time needed to restore the software). If one NAND not installed, it takes a little more than twice as long (as you have to install 40 tiny passive components too).
