| Error | Cause | Solution | |-------|-------|----------| | "Cannot find capsule header" | The .exe contains a compressed installer, not a raw BIOS | Use 7-Zip on the .exe multiple times (sometimes nested) | | "Decryption failed – invalid key" | Acer updated their encryption for new models (e.g., 2024+ Predators) | Try using binwalk to find embedded UEFI; or dump via hardware | | "File is truncated" | Incomplete download or extraction | Redownload BIOS; disable antivirus during extraction | | UEFITool shows "Unknown file" | The extracted file is a Windows driver or EC firmware | Look for a larger file (e.g., 8192KB) within the extracted folder | # Basic validation: check for UEFI signature 'MZ'
