The common key is a key in hexadecimal that is the main way of decrypting things. Every Wii U has a unique one that '''can't''' be changed or modified in any way. It is located in the OTP.bin you are supposed to save once you've made the backup to all your important files. | The common key is a key in hexadecimal that is the main way of decrypting things.

Well, as said before, it is one of the many keys used to decrypt console files. If you find '''any way''' to modify it, you're basically locked out with the wrong key to decrypt your console's contents which means you got a hard brick. That can't be recovered. The OTP is a 1024B file that contains '''all''' the keys to your Wii U console. | Well, as said before, it is one of the many keys used to decrypt console files.

The OTP ('''O'''ne '''T'''ime '''P'''rogrammable key) is located in the SoC ('''S'''ystem '''o'''n a '''C'''hip) of the console which somehow is easily replaceable but you can't write to it... Thanks, Nintendo. | The OTP ('''O'''ne '''T'''ime '''P'''rogrammable key) is located in the SoC ('''S'''ystem '''o'''n a '''C'''hip) of the console which somehow is easily replaceable but you can't write to it...

In a short way, yes. In a long way, there are multiple other part of the SoC like the SEEPROM, SLC, SLCCMPT and things like that. | In a short way, yes. In a long way, there are multiple other part of the SoC like the SEEPROM, SLC, SLCCMPT and things like that. | ||
In my knowledge, the SLC, SLCCMPT and '''''maybe''''' SEEPROM is writable. There's also the MLC but it is not part of the SoC. It is part of the NAND. | In my knowledge, the SLC, SLCCMPT and '''''maybe''''' SEEPROM is writable. There's also the MLC but it is not part of the SoC. It is part of the NAND. | ||

Why? Because, for some tools that don't already have a self extracting tool to get your Common Key when redownloading for exemple, System Files (I'm watching you JNUSTool), it can be useful to have it! | Why?

Download the hex editor of your choice. Open your OTP.bin with it. | |||
At byte 0E0 or 0xE0, select the first 32 bytes. Spaces do '''not''' count. | |||
WARNING: You hex editor might select 2 bytes per 2 bytes. | |||
Just a reminder, one letter = one byte. | |||
Copy and paste it and paste it in a notepad window for instance. | |||
And there you go! | And there you go! | ||
