Hacking [RCM Payload] Hekate mod - exFAT support and USER dump

[sweetlilmre]

Hi,

I modded the Hekate release to add exFAT support and to add another menu option to include the USER partition when dumping the emmc.
The payload can be found here: https://github.com/sweetlilmre/hekate/releases/tag/v1.1

Testing takes a long time, but I have tested a Fat32 vs exFAT dump of everything excluding USER and the files are identical.
I am testing the USER dump now, I assume that it will work provided that you have a big enough SD Card to handle it.

EDIT:

I take no responsibility for any damage / issues incurred with this release, use at your own risk.
That said, I've tested it on my switch and it seems to work well.

how do you move around the menu? do joycons work in this menu?

Use the vol + and - keys and the power button to select. Same as the original.

This is a payload for the fusée gelée exploit.
It allows you to backup your emmc, get info from your console (fuse, kfuse and TSEC) and boot other firmware and was release by naehrwert.
I have just made some modifications as per the topic.

Very nice.

So the exFAT support was already built in and you had only to turn it on, right?
Is there a reason why naehrwert disabled it by default?

 

[Imancol]

Do you think there is a possibility to dump the data directly to the PC ?. Like adding a driver to the useful load that allows to explore the data or transfer it to the connected PC after loading the Payload

I wanted to leave this message here in case someone can clarify it

sounds pretty good, i hove that i can use it in a future, for now i dont know anything haha.

Hi,

As soon as I saw that he was using chan's fatFS code I wondered why he had not enabled exFAT support.
(I am pretty familiar with FatFs, so went to check the version and exFAT switch in ffconf.h straight off).

I thought it may be something to do with the additional size of the code and hence exploit, but this doesn't seem to be a problem at all.
Maybe he just forgot?

iirc, kate mentioned having a mass storage payload. I feel like that would be what that user is looking for. Mounting the switch through USB, with access to the emmc as a mass storage device would be highly useful for brick fixes.

Looks like another user forked and added a missing dependency?

oh ok
thats what i thought, just making sure. what does "boot other OS" do tho

 

[sweetlilmre]

Just finished the USER dump and it seems OK.
There is a small issue with the progress bar, I think this relates to a 32 bit over flow in the percentage calculation, so I'll look into a fix for that.
The net effect is that the progress bar wraps to zero and then continues, this does not seem to cause any issue with the dump, though I'll have to verify that @rajkosto tools.

That will allow you to boot another firmware, from what I understand, it's limited to early versions of the official firmware at this point.

oh. so like, if i wanted to go to 1.0.0, i could run it from this? or no

 

[charlieb]

Exfat requires licensing fees, so to avoid ms issues maybe?

No, its more like when you are on 1.0.0 you "could" boot into 4.1.0 with emulated burnt fuses (so you can be able to play Higher FW games) BUT thats all guessing
