Hacking Official [Source Release] ReiNand CFW

Yea, i've been meaning to get an arm11 process running, but free time is scarce.

Yes, but svcBackdoor should be enougth to get better version string patching(I will make a test implementation). Also, what do you thing about using a buffer for the memory dumping, I had Problems dumping the full fcram without a buffer.

Ah, right, arm9 has access to that SVC too :0
Also do tell about the buffer idea

I think svc backdoor mostly exists for arm9's access xD

Every additional fwrite should append to the opened file, so using a buffer and loop while writing should prevent it from crashing while dumping a bigger part of the memory.

Edit: I testet it with something like this:

unsigned int bytesWritten = 0;
    memset(&handle, 0, 32);
    fopen9(&handle, filename, 6);
    unsigned int buffersize=0x10000;
    char* tmpPointer=(void*) buf;
    while(size>buffersize)
    {
       fwrite9(&handle, &bytesWritten, tmpPointer, buffersize);
       size-=buffersize;
       tmpPointer+=buffersize;
    }
    if(size>0)
        fwrite9(&handle, &bytesWritten, tmpPointer, size);
    fclose9(&handle);

Maybe doing a file operation and consuming to much time will prevent the system from other operations it needs to do on arm9.
Its not a real buffer i'm using here, but it works like using a buffer

Guys I'm getting a black screen just after the splash screen when I try to launch Reinand both directly from ctrbootmanager and manually from HBL after installing 3.2b over 3.1, I just replaced the files the same way as when I went from 3 to 3.1... Did I miss some step on installing 3.2?

Although I don't think the firmware.bin has changed, but did you also download the firmware.bin file?

 

[darkmanwe4ever]

I didn't, I think someone said earlier it hadn't changed. But I'm gonna try it anyway.

EDIT: firmware.bin was the problem, I updated and now it works fine. I feel so dumb xD
Thank you!

It's worth upgrading 3.1 to 3.2?

Haven't really noticed anything different from 3.1. So, I don't think you're currently missing out on too much. Although, if you do miss that "Rei" string in the System Settings, then definitely upgrade!

This might be a stupid question but may you point me towards where you are getting an updated firmware.bin?

If you are using the official builds from Rei, you can find a link to the firmware.bin file on the github page. If you are using a modified build by Aurora or someone else then you should contact the person responsible for the build and ask them which file you need to use and where to get it.

I couldn't find it on Rei's github, so I downloaded from that ISO site, it's on the post that has the cias of all the 3ds updates.

 

[Lumince]

Dont know why my post went twice but sorry

Not sure how long ago the dude updated his post with new links and files, so that might not be the right firmware.bin file. As for not being able to find it on the github, you should be looking for a link to a file, not for the file itself.

"First you'll need the firmware file that I didnt include because reasons. Get that HERE"

Oh it's right there, I just skipped the text under "Compiling", my bad. Thank you!

Read the "README.md" in the Reinand github page.

Read Aroth's comment. You can find the link to the firmware.bin file on Rei's GitHub.

Is there a tutorial for this? I tried following a video I found online and when I do Emunand, it wouldn't let me back up my SysNand, so I went ahead and started. No problems, but Reinand won't give me the Press Start menu. It only gives me the image of the girl and then reloads back to the boot menu to choose either Reinand or HBLauncher.

Ever since ReiNAND 3.0, Rei removed the press start screen. It automatically boots into emuNAND now.
Although, it seems like in your case you have MenuHax installed on your emuNAND (which is bound to happen when creating an emuNAND, as it is an exact copy of your sysNAND.), so ReiNAND gets redirected to HBL.
If you have a button set to skip MenuHax, press it upon seeing the ReiNAND splash screen (or maybe a few seconds before).
