is there any app which can extract prodinfo via payload?

k28 · May 23, 2024

got a switch here where the emmc is about to die completly. the switch doesnt boot with this emmc modul. picofly doesnt glitch with this emmc. onlyway i can see the emmc in hekate is by hotswaping the emmc. the emmc is only recognized in hekate for a few seconds only until it isnt recognized anymore. my plan is to dump the prodinfo so i can recreate a proper nand. is there a payload which can extract to prodinfo immidiatly?

prodinfo_gen.bin + lockpick_rcm.bin

Can I dump the original prodinfo, or create a prodinfo with all certificates etc with prodinfo gen? As far as I know you can just create a donor prodinfo with which you can t go online anymore. Lockpick rcm doesn't dump prodinfo as far as I know.

That payload is used to pick up a sort of draft of the console product.info which, combined with the keys, allows you to recreate a complete NAND. It is also used to inject a donor.

be quick to dump all keys. Then you can recreate a new one from scratch

Hekate(usb_tool-->eMMC RAW gpp mount) + NxNandManager

dont get me wrong and maybe i dont get it but can you elaborate a bit more? according to the creators page you cant go online:

https://github.com/CaramelDunes/prodinfo_gen

See limitations section. i use prodinfo_gen to rebuld a nand all the time where the prodinfo isnt available anymore. it works great but i cant go online with it. when using the option from scratch gamecards doesnt work. when using the option from donor it crates a prodinfo from a donor gamecards works but still i cant obviosly cant go online as a donor prodinfo is used.

thats what i want to do. managed to dump prod.keys fiel from nand. strugling with prodinfo.bin is there maybe an option in hekate/in a payload where i can just display the keys so i can manualy recreate the prodinfo?

thats what i do normaly when the emmc is working. but with this emmc that unfortunatly doesnt work. i get slow emmc, or other emmc errors. do you know any other way to grab the prodinfo?

if your emmc is dying you have no further options. either you use prodgen and create a draft of your prodinfo and with the lockpick Keys you create a new nand Or you make a raw dump + Key. stop

eMMC programmer might be your last hope

I actually have the following programmer:

https://github.com/ignasurba/mmcblkNX

Do you know if it's only possible to dump boot0 boot1 and the whole raw nand, or is if it's possible to dump prodinfo.bin only?

If it's possible to dump prodinfo only, can you please tell me the command to use?

Is the prodinfo inside boot0 or boot1?

emmc programmer can dump boot0, boot1 and rawnand.bin.
and prodinfo in sinde rawnand not boot0/1

Not sure if prodinfo can be dump separately or not, will try later myself

You actually can use NxnandManager with the emmc reader/programmer in Windows so that you could dump prodinfo partition only. In ubuntu you probably need extra special emmc program/sofware.

Just a curious question, what happen if you put some "pressure" on the nand chip? It might just be some bad solder

Tried to reflow it already but will give it a shot.

umm... if you have an emummc or a backup at all, then all you need is your prod.keys and hacdiskmount to extract your prodinfo. It's part of the backup. In fact, you can just flash your backup to a new emmc. If your only backup is your emummc and you're worried about it being "dirty", then it's no use worrying. Your sys will be "dirty" in Nintend's eyes anyway, because your telemetry isn't going to match. You are quite possibly going to get banned from online services no matter what.

Is there a specific programmer you can recommend? My programmer only supports Linux.

is there any app which can extract prodinfo via payload?
