Firmware package for the ZEED4 receiver, version V8.29 dated 26 October 2021, in an 11.5 MB zip. The same version number appears on other models in this series, so the files are not interchangeable across boxes. Unpack the archive to locate the image, then apply it through the update function or write it to the flash chip. Verify the model and main board before starting, and read out the original flash for backup with a programmer.
