Hacking How to install Forwarder Channle on Wii U ?

[pasc]

I recently got myself into the Wii U business and everything's been smooth sailing so far.

Except one thing:
How to install a forwarder channel (here: Loadiine GX2 forwarder) with WUP.

Apparantly I'm supposed to do some "Requires sig patching of some kind.", but I don't really understand how this is supposed to be done...

Any idea on this one ? (Loading the LGX2 channel via WUP as it is - obviously - just throws an error message akin "not signed")

Any help is appreciated.

PS: I've only got Haxchi itself installed (via NDS VC inject) and don't plan to go the CBHC route anytime soon.
(So if it'd be the only way to get this channel working that'd be kinda sad, as opening the HBL everytime is bothersome)

Run haxchi first, it will apply sigpatches

Open haxchi hold B shud restart reopen haxchi then click wup

Open haxchi hold B shud restart reopen haxchi then click wup

Perfect ! That worked like a charm.

The Wii U keeps throwing an "error please turn off wii u" when I launch the channel, but apparantly that is probably another story.

Now the channel is installed.

Boot up Wii U, run haxchi, then run the channel you installed.
You need to run haxchi first as the channel is fake signed and requires sigpatches to launch

Ah, k, makes sense.

I suppose there is no way - by means of any kind of trickery, to produce a properly signed fwd'r ?
(F.e. injecting it into another app already present on the Wii U (similar to how haxchi is installed ?)
