| Issue | Likely Cause | Solution in v20 Hot | | :--- | :--- | :--- | | "SELF decryption failed" | Your EBOOT is already modified by another tool that uses different keys. | Use the Cleaner tool inside v20 Hot to revert to a clean dump, then re-resign. | | Game boots to black screen | The EBOOT is resigned for a different firmware (e.g., 4.82 on 4.91). | Re-resign, but this time in Settings force “Target FW: 4.91”. | | SPRX not showing in game | The SPRX was not re-signed as a FSELF (File SELF). | Use SPRX Mode and check “Force eLF to FSELF conversion”. | | Antivirus deletes the tool | False positive due to binary patching routines. | Add the whole folder to your AV exclusions. v20 Hot is open-source (check its SHA hash on trusted forums). |
