ZIP archive whose name refers to a dual IMEI repair method for a device called moon or tides without using hardware tools. At only 256 bytes, the archive is almost certainly empty or holds just a tiny text note or link, not a usable tool or firmware. The name does not identify a brand or exact model. Open it to inspect what it actually contains before relying on it. Note that changing IMEI numbers is restricted or illegal in many regions and should only restore the original values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @mrepairo. Enginerys does not host this file.
