My friend used the Wii Softmod guide for 3.x-4.1 via an SD card
After he finished he put a (working) backup DVD in the Wii and NeoGamma v7 gave a 1101 error message.
The forum search results suggested we try NeoGamma v6, but then we got a 972 error message.
My friend uninstalled NeoGamma and restarted the console.
Now it only shows a dark blank screen.
Is it bricked?
We did do a system backup to an SD card but nothing is functioning!
I think I will have to take it back to the shop and exchange it because it was bought recently.
Sounds like a brick to me but you should be able to find a solution for it in this section of the forum.
BRICKED Wii Issues ONLY
Sounds like your friend uninstalled one or more of the following
If I am correct the wii is full bricked unless you have boot2 bootmii.
If I am wrong
Boot2 bootmii is good to have
Preloader/priiloader would also help
You could pray and try savemiifrii
