Apple Silicon Soldered SSD Upgrade Thread

can we use 1x KICM229 (1tb) to upgrade a 128gb model of macbook air m1 A2337?
It has only 1 nand slot populated.

@Sauve Mon Mac thank you I found a supplier yesterday wo sells them for 150 euro shipping to Germany.
By the way you said you can Blank them with P15, but dosdude said once you write into them in dfu, they will not be usable anymore on other devices. that means you can not take an original 1tb nand from one laptop and format it and upgrade another laptop with that nand.

Some you can actually blank now with P15; they have somehow managed to get dumps of "blank" firmware from some NANDs (not all though). So for the ones where blank dumps are available to flash, you can make them blank again.

You cannot, no. It is not possible to deviate from any valid configurations, which are listed here. In any instance, 2 NANDs are required on any standard M1 machine to achieve 256GB or higher.

You can blank them with P15 ! Just chose iPhone 13 and then click format Nand

Thanks @Sauve Mon Mac , that worked great. Successfully upgraded from 512G to 2T.

@prageethk what was wrong with it at the first place? what did you do wrong?

As @Sauve Mon Mac suggested, I triple checked for any components fallen off by comparing to another dead board. I had RP001, a tiny resistor probably 0201 that was responsible for NAND0_CLK24M_01, which sounds pretty important, knocked off the board. I finally managed to get it soldered with no microscope. Then I blanked the NAND chips using the P15 programmer using the iphone13 menu. Soldered it in, viola - this time all succeeded.
