Redownload Zip File

The Magisk Process Error Installation Failed error usually occurs due to incompatible or corrupted files. If you download a file with a slow internet connection, there is a slight chance that the download may become corrupted. Therefore, it is recommended that you check the downloaded file with its checksum or download it from an official source to avoid encountering this error.

Check Zip Format

Occasionally, the flashing zip downloaded from the internet could be in 7z or RAR format. To obtain the Magisk-compatible ZIP or IMG formats, you must extract these files.

Check App Storage Permissions
