I've been doing the tests for all the M3 firmwares available.
They do say a picture is worth a thousand words, so:

 

Try launching it from sysnand to be sure. (also devmode does not patch TWL_FIRM, so don't use it for this)

 

Install TWL_FIRM on EmuNAND, install launcher on Sys- and EmuNAND, IIRC.

 

That error screen also occurs if you're using the old version of @Aurora Wright 's patched twl_firm. My wood R4 wouldn't work until I updated it. Running on sysnand.

 

Tryed it, still get the Error screen. Might be something with the card, will try it on the DS of my brothers friend if he has time.

 

There's something wrong with your setup. If it was the card, you'd see a no UI themed WoodR4 menu with no text.

You'll need to uninstall it using FBI first or use DevMenu 2x to overwrite it. I believe FBI may uninstall it for you. But that didn't work last time I tried. (is using FBI, be sure to set destination to NAND first)

 

Should I install it to sysnand or emunand?

 

In BigBlueManager (I think) it says I can enter start + y to "update firmware" , should I do this to install on emunand


Edit: I tried this and it came up with an error

 

Just got done doing DSTT:

DSTT_Launcher.rar

I can do YSMenu next, but it's unlikely to work. The builds of YSMenu I've tried haven't worked.

The above launcher I just posted boots to two white screens with a animated progress box icon in the bottom screen. Looks like it's trying to load DSTT stuff, so might work for those who actually have DSTT. I can't test it further as I don't own one.

NOOO! That's only for NATIVE_FIRM! Don't use that command for anything else!

 

Hmm, I did as you said and used fbi manager to install the patched twlfirm and it deleted the other one and it installed fine. I then installed the cia but when I load the r4 it says error and I need to power down the system

Any idea of what I did wrong? I have the wood firm on my r4 original already

I think it is because I didnt install the cia to sysnand, how would I go about doing that
