A2141 MacBook Pro 16 820-01700 SSD Error

[loic2907]

Hi all,
I have one SSD side of the motherboard (U9100, U9200, U9300, U9400) which is dead.
In fact, the 1v8 SSD and 2.5 SDD was short with the NAND
Is this possible to replace these NAND ?
I heard about encrypted NAND with the T2
It's seems to not boot even if these is no remaining short on the motherboard

First of all, welcome to the forum.

You need to get the NANDs from scrap baord and place them in the same position.
If not (like new chips), you need to initialize them with P13 programmer.

You may also pay atention to SSD capacity.
Sometime can solve the problem soldering only 2 NAND chips.

Many thanks for your reply !
In my donor, it seems I don't have these capacity.
I checked with the capacity written on the box and after with the BOM.
Do you have any advice to check capacity of the NAND ?
I'll try to buy new one, do you have advice too ?
I will buy P13 too

You can buy pre-programmed NANDs kit on Aliexpress; not cheap at all.

Search with Google for the codes marked on your chips.
Your baord has 5, or 6 NANDs?

Will check video later thanks
Pre-programmed NANDs that's mean I don't have to buy P13?
My board is a 1TB so 6 NAND.
I have 4 dead NAND
Here is my NAND TSB42280W3197TWNA12006

Just checked the video, this is incredible !
Did you used P13 to do something like this ?

 

[2informaticos]

P13 software allows you to initialize the NANDs for various MacBooks.
Pre-programmed NANDs from Aliexpress come marked; to know where you have to solder them.

We have more threads on the forum, about 01700 SSD problems; just check them.

 

[loic2907]

What is 01700 SSD ? And where did you find this reference on my chip ?
I would like to decode the number written on my SSD to know the name of the chip, etc . If you have any idea?

 

[2informaticos]

01700 is the refference of your MLB, 820-01700.

Not easy to find the capacity of the NANDs by their marking codes.
But you have good information on pages 2 & 3,
As you have 1TB SSD version, this implies the presence of 6 NAND chips; which can be manufactured by Toshiba (TS), or Western Digital (WD), page 2.
Having T2 version 2, you can upgrade the SSD until 8TB.
In page 3, you can see your chips are 192GB in size, each one (TS).

TSB4228 is listed many times as 128GB on Internet.
I didn't find information about the capacity considering the full code name.

Any reason to quote an entire post, visible few centimeters above?

Thanks for you reply, I can order other capacity so ? 4TB for exemple ?
Ok, will check it so ! For you, is it important to have P13 in your tool ?
I edited my posts

 

[2informaticos]

Good to have P13, if you have many scrap boards to get NANDs.
Then you can configure them as you need.

 

[loic2907]

Did you have tutorial for this tool ?
Because I checked the software JCID Repair, and there is only 2 options for my mac.
No option for the 2,4,8 TB for exemple.
Did you already used it ?

I don't have P13 programmer...
