Hacking Question sx os license and emmc module swap?

[Romain80200]

Hello,

I've got a question about sx os and the emmc board swap.

If I got my sx license activated with my old emmc module, swap the emmc module and restore my nand backup inside, does the license will still be valid?

Is the license tied to the emmc module serial or just with the prodinfo or the switch serial?

Thanks.

I think you will need a new license

When you only change the emmc chip and not the console, then the license is valid again (licene is console fingerprint bound)

So better keep my original module clean and activate the sx os after installed the new module and restored my nand backup into it.

I will try as soon I get my new module.

would you like use a second emmc chip for cfw/sx os?

 

[Romain80200]

Yes, one for cfw offline with nsp/dlc installed and the other for official os and online when the new firmware will be cracked without the risk of sd card corruption because of the emunand.

I just got a second hand switch for 150€, not banned, like new with just a joycon stick to change.
Now I just need to prepare it for chrismas and keep it clean just in case.

I believe a portion of the fingerprint is derived using the emmc serial? Could be wrong though

The sx os license it's tied to emmc if you change the emmc the license will not be valid anymore, i used this info to transfer a sx os license from a faulty ns to another ns.

Yes it is tied to the emmc module serial.
The person posting above me, @npavlovici, has actually managed to transfer an SX OS license by transferring the emmc module, as he stated above.

I suggested the idea to him by linking the same thread he linked above in this post:

A bit off-topic, but I have an idea for a side project you might be able to try...
It seems SX OS license is tied to a unique ID based on the eMMC chip, based on this post:

Maybe if you have another Switch with no SX license you can try this as a side project:

• back up NAND on unlicensed Switch
• replace eMMC of that Switch with the eMMC you got from this broken unit
• restore NAND backup and check if SX OS license rights was successfully transferred

It's not really that useful of a project (after all, SX OS isn't that expensive), but it'd be fun to see if it works.

And he got it working, even giving a step-by-step guide:
