Hacking Nand Dump - Downgrader / File Changer

[Gonzo]

To be more concret with the technical informations from 3DBrew (www.3dbrew.org/wiki/Flash_Filesystem):

150 MB - 500 MB = 0x09.600.000 - 0x1F.400.000, so you oerwrites parts from the twlp, firm0, firm1 and nand filesystem.

It would make more sense to replace just single partition firm0 and firm1 from a dump of a different firmware version, in hope that 3DS except it.

3dbrew is our friend: http://3dbrew.org/wiki/Flash_Filesystem#NAND_structure

As i said, you can't bypass the console unique encryption. That it runs if you change or corrupt some userdata, means nothing.

To slow.

Already tested. It won't boot, even if i use my own NAND image from a different firmware.

I'm trying some thing in same way just for fun this dump are from my console

i cut my two dump in 150 mb files and swap files finally just the second part of 150mb in a 4.4 firm is need to have gateway expoit on a 6.3 firmw ( but after you can't launch the gateway blue card and your console says 4.4 )

Well...

At this point, have you try to update to 4.5 firmware???

If you have succes updating, may be you find a weird, but effective downgrade.

 

[bandicoot37]

it will work certainly but haven't got a 4.5 game

 

[Riku]

So if my system on 4.5 and I update to latest 6.3, go to eshop and purchase game or dlc. Then write back 4.5 backup image and 0x0B95CA00-0x2F3E3600 from 6.3 backup. So download tickets will be in place and purchased games will appear on 4.5?

 

[bandicoot37]

i think yes

 

[Coto]

something quite useful would be to lead bootroom to run the update partition from cartridges...

 

[borgia]

it will work certainly but haven't got a 4.5 game

If you have the GATEWAY card, you can try with a rom wich contain this update.

As far as you have a NAND DUMP, you're safe.

Try and post, please.

 

[bandicoot37]

no when i'm on a 4.4 firm and launch luigi mansion 2 in gateway , it doesn't ask me to upgrade my machine

This can be for the firmware spoofing on Gateway 1.2

You can try with Gateway 1.0 filesystem. Then, it must ask you to update. If not, the console think you're on upper firmware.

Cheers.

 

[bandicoot37]

OK when i'm on 4.4 i can update
try to see with the 6.3 patch

 

[bandicoot37]

ok console ask me to update 4.5 with a 6.3 firmware with a patch with my 4.4 block 150mb-300mb

 

[vini9157]

ok console ask me to update 4.5 with a 6.3 firmware with a patch with my 4.4 block 150mb-300mb

please make some videos.

And ppl please try the same mod, we want to know if its true or not

 

[Lucard]

I hope in the Future we are coming futher...
unfortunately i have only a nand backup from my 6.3 Firmware... this is bad

Oh and guys have anybody a program to see the nand as binary or hex ?
I dont find a good programm.


Thanks


And a quastion

what would happen because if I turn on the 3ds and am in the system menu then connect it with my pc on the sd card reader ?

has anyone tried this? on are we still reliant on keys (breaks keys)

You erase your purchase info, already done by someone.

it's stored in CTR-NAND partition and not in firmware area. writing that partiton from 6.3 firmware restores 'purchase info'

And have you done a user side transfer?

 

[AgoraphobicNosebleed]

I swapped my 6.3 CTR-NAND partition into my 4.4 dump and it fails to boot.

 

[n1ghty]

Already tested. It won't boot, even if i use my own NAND image from a different firmware.

I tested this a few weeks ago and it worked
4.4/4.5 firm1/2 with 6.2 system.
