Discussion Info on SHA-256 hashes on FS patches

Just chill dude, there's things going on that you don't know about that are not public. It's more difficult to make an auto patcher because of patch 3 and the amount changes between firmware versions. However I am sure if you wait a little while something will be released. It's better for everyone if ALL the bugs are ironed out and we all fully understand the patches, before anything gets released. There's more than enough info now on this thread now so that quite a few people will know how to make patches, and things have been simplified greatly already. Patience is a virtue!

 

take all the time you need i was just ask if its possible seen how difficult it is compared to the loader and fs patches
Thanks for everything you have done

 

@crckd:

Ok thought of a good workaround to fix the patches :-)

In the batch file you created you can also search for this: SDK Version: xxx, then create a text file with the sdk version, that can then be read by the makeips file.

Example:
Firmware 11.0.1
SDK Version: 11.4.0.0
Version: 11.0.0-1280 (738198784)

Firmware 10.2
SDK Version: 10.4.0.0
Version: 10.1.0-256 (672137472)

Then in your makeips file, use 2 sets of patches - 1 set for firmware with SDK version 10 or less use patch set 1, if the SDK version is greater than 10 - use patch set 2. That way if the patches change again on higher sdk, that patch set could also be added to the script easily. That would be an easy way to solve our problem.

This was added to the end of the python file to check sdk version & create a txt file containing that info:

Code:

outlines = subprocess.check_output(['hactool','--keyset=' + keyset,'--disablekeywarns', FIRMWARE_DIR + '/' + ES_NCA])
            for line in outlines.splitlines():
                line = line.decode('ascii').replace(" ","")
                if line.startswith("SDKVersion:"):
                    f = open("sdk.txt", "w")
                    f.write((line).replace("SDKVersion:", "").replace(".", ""))
                    f.close()
        
                    #read back file to make sure our file got created properly...
                    f = open("sdk.txt", "r")
                    data = f.read()
                    f.close()
                    print("SDK:" + data)
            break

Output:


Next - read data in makeips file and check if greater than: xxx - example:

Code:

f = open("sdk.txt", "r")
data = f.read()
f.close()

value =  int(data)
if value < 11400:
    patterns = patterns2
else:
    patterns = patterns1

 

Done! Got the ES patches bit finished. Don't know If I can share or not as it uses some code that was not made by me + plus it's a bit "hacky", but generates all the right patches for now. If I get the OK from the person that gave me the code, I'll post, but maybe they want to change some stuff first or keep it private. I expect you'll find out soon. But at least that's me done with this now :-)

 

fingers crossed that he/she/non binary allows the use of it then, because this will be a real game changer

 

Agree 100%.
With these scripts and proper documentation, we won't have to worry as much about sigpatches or Nintendo going after repositories that host them.
With this, users can easily generate their own patches.

 

Mate, I love these kind of threads... where adults work together in harmony to create great software for the benefit of everyone

It really brings me back to the days just before a9lh with Dark Samus and all the guys working on it on freenode (i think), those were really good days

 

Thanks man

 

Thanks, you should also put important on this one for the FS patches.

@mrdude happy to confirm patches made with your script work great tested on 10.0.4, 10.2.0 and 11.0.1

Big Thanks to you @mrdude @crckd and @DarkMatterCore

Now that we know the basics, I think this will be next.

1: Clean up/mod/improve scripts and write a batch/bash menu to incorporate loader/fw/es patches into 1 tool.
2: Create a windows standalone GUI program so we use without python.
3: Maybe some dev with good c++ coding knowledge can make this work directly from the switch?

 

@Homlet maybe now you can integrate all the scripts in your aio-switch-updater the es patcher works

 

Is this the right output for the latest AMS and 11.0.1? 1xES file, 2xFS files and 1xLoader file?

 

yes 1 es file for 1 firmware version 2 FS = 1 FS for Fat32 and 1 for ExFat and 1 for loader

 

Thanks, is it possible to know which is for fat32 and which for exfat? Not really that important but interesting to know.

 

the script first makes for ExFat and then for Fat32 you can see which is which in the command window

for 11.0.1 ExFat is

0BA15BB304B505633B6DA6B2C6E991B6A06EBAFB3378DF02BF6B494075976F06

and 11.0.1 Fat32 is
