Error 40 help please!!!!🙏🙏🙏😩😩😩😩

[Albo221]

I can't figure out error 40.

I've tried everything I could think of
I've tried everything on here but still having issues with error 40.

You must solder another NAND, for example from iphone 5s- if same error 40, then it is cpu or pcb fault. Ip box does not repair hardware.

and also check the capacitor value near the nand ic

Will a iPad mini nand work?

I have a couple iPad mini nand I pulled off of dead boards.

Do i cope over boot1 ce1 & boot 2 ce2 to new nand?

And one more thing. I was told error 40 is also caused from nand not attached or bad reball is this true?
Sorry for so many questions.
Thank you for answering back.

This is after nand take off and cleaning.

At first not need any ip box or another, just working NAND from 5S 6 air air 2. From mini 1 i dont know for sure, i think it will also work but without serial number.

[maxieboy]

the pin on nand is complete ? the picture is not clear enough , take some good photos and post again

[Albo221]

I pad mini nand looks clean and looks the same as iPhone 6 nand on back side


I took closer picture of nand removal and clean board better.

try to change new hdd without touch the kernel. just program to itunes and if success put the serial number on new hdd and restore again

I also still have error 40.

100% not board damage because i restored with a good nand from china....
But if i put my own nand in with changed serial. Error 40...
I tested it before changing the serial so it is for sure the ip box that does something wrong with the 64 bit units.

Followed maxieboy steps but doesnt solve anything..

I'm still having issue.



Nand from iPad mini



Still error 40

I have been working with IPbox for sometime now.

And have realized that Ipbox has the capability to write sn and all other information without apple firmware in nand.


Previously even i used to erase the chip and directly write the required information.

It would obviously write the S/n and other information. But when you try to restore the phone you will be prompted with error 40.


what i have realized is that this is a 2 step process.

First we need to save the info from the chip

Then erase the whole chip.

Now reball and solder back to the phone.

Restore the phone. (phone will be perfectly restored but you wont be able to activate it)

Now Desolder the Nand once again and write the S/N on it.

Solder it back.

Done. (No need to restore it again)

Now you can perfectly activate and use the phone.




Hope this helps someone.

Okay it restored with iTunes
What do I do now? Take nand off and just write sn?
Do I enter my own sn and hit fix invalid serial number?
