Did you backup your DSi's NAND with fwTool?

 

[Deleted User]

Did you backup your DSi's NAND with fwTool?

nope, so I have to get the tool? I managed to get leaked ugopwn so is fwtool runs on DSi right?

 

[dpad_5678]

nope, so I have to get the tool?

Yes. You also need to have Flipnote Studio installed. Were you already able to find a copy of the leaked ugopwn entrypoint?

yes I have all of these.

 

[dpad_5678]

Alright. Do you have the newer payload.dat file? If not, here are the files you're going to need anyways.
Copy both .nds files and the payload.dat to the root of your DSi's SD card, and overwrite the existing payload.dat.

What froze? During what step? While inside hbmenu or while trying to launch ugopwn in Flipnote? Please be more specific. Make sure you're following the ugopwn instructions correctly:

Place payload.dat on the SD root, and ugopwn in the private\ds\app\4B475545 folder.
Then, open flipnote, and open the ugopwn folder

Select the flipnote with one frame(should be Flipnote 1) and copy the frame
Then, open Flipnote 2, open the frame menu, and press right until a new frame is made.

Now comes the fun part: Click the paste button 122 times, or at least as close to that as you can be
Then hit erase, and it should bring you to frame 2.
Click paste, then stage 1 will load stage 2, to then load your .nds
Congrats! You should be running the .nds now!

If you're using the files I gave you, you should have a HBMN.nds on the root of your SD card. That's what the modified payload.dat loads.

You want to select "Dump CID", and press A. Then, you want to select "Dump nand_dsi.bin". This will backup your CID (also known Chip ID, different from your console ID) and your system's NAND.
