Same question as topic. I've repaired my 4.X console's L button, which need to withdraw the console's battery. Before repairing it, my another console can tag both 4.X and EmuNAND 's Mii Plaza. After repaired, EmuNAND can be still tagged properly, but 4.X is unable to be tagged anymore. That's the reason why I want to format 4.X's system memory. I don't know if after getting it formatted and re-cracked, the current EmuNAND is able to be recognized or not.
