Hi

dosdude1​

I have A2348 and I was trying to upgrade but I lost some components. Is it possible to know what these capacitors cost and where I can get them? Thank you for your reply.

Those should be AC coupling capacitors for one of the PCIe lanes, they are 0.22 uF 0201 capacitors, you can buy them from any electronics component distributor.

Sorry for the long post. Is it possible that it will be affected capacitors In the heat I don't know its value
 
This component flew away and I prepared to weld it. Could it cause harm?

can we use this method of to write the data to nands for m4 air and base MacBook Pro m4(2 nand configs) with the config of an m4 Mac mini?

little unsure as it uses u8600 and u8700 instead of un000 and un100

any ideas?

Yes, that should work fine assuming the dumps provided by JCID tool are good (I have ran into some that were not).

The upgrade was successful, thanks to God and your grace, but after the upgrade the speed decreased read

A simple note NANDs general state

Probably used re-programmed NANDs, if so, DD-ing zeroes to the whole drive from recovery mode and performing another DFU restore afterwards will resolve it.

Is this an essential capacitor or just a decoupling capacitor? Not exactly sure how to tell the difference

The method worked.

In the future, please don't add underfill-like material back to newly installed chips. It doesn't do anything, as real underfill is actually injected underneath the chip with a tiny needle and hardens underneath the chip as well as around it (for structural support), which anything that requires UV light to cure obviously won't be able to do. Adding material in-place of underfill in the manner you did doesn't do anything other than make a huge mess the next time the chips need to be removed again.

You are right
 
Hi guys,


I hope you’re doing well.


I’m writing regarding NAND chips. Have you noticed a sharp increase in NAND prices recently?


Back in February, my supplier sold me new/blank 1TB Kioxia K6B2 chips for $83. Today, I wanted to order more, and he quoted me $143 per piece 🤯.


Is this price increase due to a market shortage, or is my supplier just trying to make more profit? 🙃


Thanks!
 
Hi

dosdude1​

flashes white mac mini m1



When I restore, I get error 4014.

Can you identify the problem?

Update after blinking white light When I click on nand It works

Does this mean the problem is with the NAND soldering?

Or in the capacitors that I replaced?

Well done on the amazing video collab! Great work pal….

Just a quick one how did you get to this screen in the video to conclude the m4 NANDs had an issue and narrow it down to that as instead of Linus not making a mistake?

Was it the error message that was thrown up? And how to we know what these error code mean (beyond having to trust a random google answer)

Noticed an increase in m4 NANDs particularly…. But m2/3 have held a steady price from my knowledge. Frustrating as it’s hard to tell exactly why this is the case

Thanks to everyone that has contributed to this thread especially @dosdude1

I have an M3 Pro MBP with 4 x 128GB K5A3 chips. Do I need to replace these with 4 x 1TB K5A8 or use the K6B2?

Thanks.

The "Error occurred while formatting the NAND" error is always indicative of an invalid NAND config, whether it's unsupported NAND models or NANDs installed in an invalid config (for example, 4 1TB NANDs on an M1 Pro/Max MBP). Annoyingly, at this stage it has already programmed a bad config onto the NANDs that are installed, so unless you have a valid set of dumps for them to program back on with P13/P15, there's not much you can do at that point.

This log itself is produced when using Finder on Sonoma or later to perform a restore, and it will save the log for each restore done to ~/Library/Logs/Mac Updater Logs.

Has anyone been able to upgrade a 256gb M4 MacBook Air NAND yet? Unable to find out which chips I need to get

Should be the same as M4 Mac mini, so either K6B2 or SDSFGKLKH would get you 2TB.
