I have the same problem here on my old 3DS 9.2.0-20U. Tried with the newest rxTools build and with the 2.6 Build, even with a build between those. Always the same result... On 2.6 there comes "Could not find H & S TMD / content" and with the newest one, if I only want to check the Version, it only says Region USA and nothing else. Also tried just to flash each of the 3 different versions in the injecting folder with hope, that one of them is the right one. But the Tool just say, that the H&S information is missing and nothing change within the H&S app. Have also updated my emuNAND to the newest Firmware, but no changes. Can anyone help ? And is it normal, that the rxTools say every time, that the installation is failed ? Are there any other ways, so I can skip this step maybe ?
