| Error | Likely Cause | Solution |
|-------|--------------|----------|
| “Update file not found” | Wrong file name or USB not FAT32 | Reformat USB to FAT32; rename file exactly to update_signed.zip (case-sensitive). |
| Update freezes at 23% or 89% | Corrupted firmware file or bad USB sector | Redownload the file from a different source; try a different USB drive (older, smaller capacity drives work best). |
| Projector won’t turn on after update | Power loss during update or incorrect firmware version | This is a brick. Try the “Emergency Recovery” below. If that fails, contact Wanbo support for a motherboard replacement. |
| Autofocus/keystone is worse after update | Residual settings conflict | Perform a factory reset (as recommended above). Then recalibrate keystone manually. |
