Apple Silicon Soldered SSD Upgrade Thread

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
This listing says it converts a BGA315 chip to a BGA110 outline. It says it supports various iphone, ipad Mac Mini iMac and M1 M1 Pro MacbookPro models.

It is very had to find BGA110 chips for M1 Pro models at the moment (KICM223, 8T85 etc). Is this a solution so that we can go for chips like K5A8 on M1 Pro models? Has anyone tried it?

I have a question about the JCID P15 programmer. Is it a great tool? Can you customize the NAND flash memory, or does it have to use the factory NAND firmware to ensure proper soldering and avoid problems during DFU resets?

LB Tool H7 has more general firmware I believe

MacBook Pro 14 M4Pro 4xK5A5 config not working. Tried 2 china kits of NANDs (Error 35)

4xK5A8 also doesn't work 🙁

Bought 4pcs HN3T2DT8CAX383 from china. Also doesn't work on 14 M4Pro. How the fkng get 2tb config on this piece of ****?! arhhhhg
 
All this talk is having me consider having my M1 MacBook Air's SSD upgraded to a 1 TB one by a specialist, since I am now running low on internal storage. I'm looking at L2 Computer Inc. for this, and it'll cost me around $350, but it should definitely be work the expense. I'll likely place the order later this month after I get a couple more payments from my summer baseball mascot job. Then I should be able to get a few more years' usage from this Air!
Don't worry about my getting my own computer work done during the upgrade; I'll just use my "backup" Mac (a 2019 16" MacBook Pro with 2.6 GHz 6-core i7 processor and 32 GB of RAM; it's ALMOST as fast as the M1 Air) during that period.

I did try doing this with K5A5, but it did not work, though was likely due to the JCID firmware for the K5A5 just being bad in some way. Just try with K5A4, in theory it should work. Just flash each one by selecting “Format” option in JCID with iPhone 15 selected, once it writes the firmware it should read as being in a “general state”. Once all 4 are programmed this way, they should work fine in any valid configuration, and get programmed appropriately during DFU restore.

I tried doing this on a MacBook Air M4 with two K5A4 memory chips, but it didn't work. I ruled out the memory chips by testing four different ones, and it always fails with the same error. I don't think this JC erase method works on this model.

Anyone have a good line on new kicm229 or compatible NANDs these days? Getting some other work done on a M1 Max 16” and got a good quote for labor to go 1TB to 2 at the same time if I can source the NANDs
 
I am replacing the memory in a MacBook Pro M3 Pro (A2992) with K5A4 memory chips.
I am installing four chips. The memory was harvested from an iPhone. What needs to be done to the chips so that the laptop can be restored/flashed? Do the chips need to be programmed, or can I simply flash the laptop via DFU mode?
Currently, during the restore process, I get the error: "Failed to restore device in recovery mode, libusbrestore error:2006 [com.apple.MobileDevice.MobileRestore – 0x7D6 (2006)]".

Well, last Friday I placed the order and had my M1 MacBook Air shipped to L2 Computer Inc. (but of course I did a Time Machine backup before packing the Air), and it came back today with a nice big 1 TB SSD!

Restoring the Time Machine backup, first things first. They even fixed the peeling bezel gasket for no extra charge!

I gotta say, including the shipping and tax costs, this was $400 well spent!

Now I'm copying over any new or modified files on my "backup" Mac (my 2019 Intel 16" MacBook Pro) to the M1 Air's new 1-TB SSD via Target Disk Mode! It'll be good to do productive audiovisual work on the MacBook Air again, as that 2019 MacBook Pro did feel noticeably slower in comparison (even with a 2.6 GHz 6-core i7 processor, 32 GB of RAM and an AMD Radeon Pro 5300M GPU with 4 GB dedicated VRAM, compared to the M1 Air having 8-core graphics and 16 GB of RAM).

Hi, the 2xk5a8 and 2xk6b2 configurations don't work on the M4 mba (A3240 and A3241). Only the 2xk8a5 configurations work on these models.
 
Hello everyone!
MacBook Pro M1 Pro A2485, board 820-02100 — error 4014
Initially, the MacBook stopped booting normally. An exclamation mark appeared at startup, and Recovery Mode requested a restore.
The service center decided to replace the NAND.
After the NAND replacement, the restore process starts and the Apple logo appears for about 15 seconds. Then error 4014 occurs.
Measurements on the board:
  • PP2V5_NAND0 — 2.54 V
  • PP1V2_NAND0 — 1.24 V
  • PP1V8_S2_NAND0 — 1.80 V
  • PP0V9_NAND0 — 0.84 V
  • NAND0_OCARINA_PGOOD — 3.73 V
  • NAND0_RESET_L — 1.24 V; it goes high during the restore and does not drop after the error
  • NAND0_PCIE_RESET_L — rises to approximately 1 V when the restore starts, then drops when the error occurs
  • NAND0_CLKREQ0_L — approximately 1.25 V; during the restore it briefly disappears several times, then remains present after the error
I also found signs of significant heating around C5821/C5840; these capacitors had previously been replaced.

My main question is: Could error 4014 in this case be caused by incorrect preparation/programming of the new NAND set rather than by a hardware problem on the board?
Which lines in the attached log could indicate the actual cause?
I’m attaching the restore log with the error.
Any advice would be greatly appreciated.

Hello everyone.
While repairing the A2485 board, I encountered a problem: error 4014 was generated due to an incorrect memory dump for the KICM232 NAND flash (160GB). Does anyone have a working dump or a verified configuration for this chip from the donor board?

I would be very grateful if anyone could share the file. Thank you very much in advance!
