Ugothacked

This tutorial should help you bypass 20102 completely, there are multiple reason why you might be getting this error, its basicly a ban, it doesnt allow you to go on wifi in any game, the reason would be that nintendo has detected the homebrew channel ticket in your system or they have cough you hacking online... You can call nintendo nintendo but they will only unban you once, and if you still continue hacking or you leave the homebrew channel in your wii you will get banned AGIAN and if you call they will NOT unban you this time. This tutorial is for the ppl that had hack online and kinda regret and wanna play fair once again... Please do not abuse.

There are 2 different types of 20102 bans, theres the MAC ban, meaning that they banned you wii's MAC address, theres also the SN ban, meaning that they ban you wiis serial number, not completely, ill get into that later on..

Ill be teaching you the "Main.dol" method, wich i find to be the most effective and easiest.

What you need:
1) Wii game
2) Wii Scrubber
3) Hex editor

Steps:
1) Open up wii scrubber and select a game.
2) Find the "main.dol" and extract it some were you will remember
3) Open up your hex editor, and open up the "main.dol"
4) Go to File then Find
5) Make sure that the "Find" is in Hex search and type 7F83E378 38A00006
6) Your hex editor will search for it and highlight it
7) At the end of it you will see the "06" change it to "03"
8) Save the file
9) Go back to wii scrubber and replace the main.dol and you are unbanned from that game!

You have to do that for every game that you wanna get unban.
Are you to nooby? heres a video on how to do it:

If some how you manage to brick you wii, I am not held responsible, it is YOUR choice to follow this guide it work for me and nothing bad happens as you can see in the video bellow.

Tools:

Steps (wii):

1) Go to the Homebrew channel
2) Seach for the FSToolbox appthat you just downloaded and placed in your SD card then boot it
3) Select IOS 36 and press A
4) Press A again
5) Go to Shared2 folder and press A
6) Now there should be new folders and files
7) Move the cursor to DWC_AUTHDATA and press the MINUS '-' button on the wiimote
8) Once the file gets dumped press "home" on the wiimote and power off you wii

PC time:
9) Open up your hex editor
10) Load DWC_AUTHDATA file (in shared2 folder)stored on your SD card on FSTOOLBOX folder (Remember to backup that file!!)
11) Add/sub a hex value to the 8th byte.. then save it and insert your SD into wii

Wii time once again:
