Hacking 'SysNAND backup Failed'

[Shinzetsu]

So today I was using DSiware transfer to mod my n3ds (still modding as im typing) and when i try to backup as it says in the 3ds guide, i am told that it is failed to backup.
What should I do? I have done everything right (i think) up to this point.
Also, on the source can I get my games back? I have backed up SD and NAND. It said no where in the guide about getting games back.
Edit: Yes the RTC time does match.

On the source you can get your games back by restoring a NAND backup made prior to the transfer and using the old SD card contents. A NAND backup failing usually means there's not enough space. Check you have at least 2GB free and if you do, check your SD card with H2testw https://3ds.guide/h2testw-(windows)

Alright, I'll try that now. Thanks!
Edit: I restored my NAND (prior to me transfering) and my games haven re-appeared. I'm using my old SD that I backed up before too. What am I doing wrong?

Did you also put back the SD card contents from before you transferred? If you moved the SD card over when the transfer told you to you can just put it back in the source, or delete the Nintendo 3DS folder that's currently in the source and copy back the one in the target (assuming you moved the data over as instructed).

I got the same message. Is it really needed to do a NAND backup?
