Homebrew DSiWare backup installation

[MaxiBash]

I found this tutorial at https://dsiguide.me/dsiware-installation , and It went well, until I got to step 5 & 6 at Section II:

5. Look at the tmd file (that you just copied over!) for your backup. If it ends in .0, rename your file "00000000.app" (there are eight zeros) For .256, name the backup "00000001.app" (there are seven zeros) and for .512, name the backup "00000002.app" (there are seven zeros.)
6. Rename the tmd title.tmd.

You can look up the tutorial yourself, but I keep getting that the SHA1 don't match.
What can I do?
(I'm new to the DSi-hacking scene, so don't expect I'll understand everything quick)

I created this tool: https://github.com/MrJPGames/NDS2Hiya/releases.

You can install DSiWare in .NDS or .app format (they are the same files just a different extension).
Just select your SD card drive that Hiya is installed to and either choose a folder with your DSiWare backups or select just the singe .nds/.app an it will install it onto your HiyaCFW SD.

Ok, still stuck at the HiyaCFW installation, I’m going to inform the creators behind that thread so we can both figure out what I’m doing wrong.

Oh I just read the title and scanned your post very quickly.
Yeah you're simply following the wrong guide, nobody should use that guide!!
Use https://dsi.cfw.guide/ instead!

After that you could use my tool to actually install DSiWare backups.

My boy,
the intire HiyaCFW got copy-pasted, it’s the same tutorial :/

Just redo it with that guide, it will work!
