""" MOTOTRBO CPS 20 v2.2.6 – safe download helper
| Step | Action | Why it matters | |------|--------|----------------| | A | Opens the official Motorola (Hytera) download portal in your default browser (or fetches the direct download link if you prefer a CLI download). | Guarantees you receive a clean, up‑to‑date installer that respects the software license. | | B | Verifies the SHA‑256 hash of the downloaded file against the hash published on the official page. | Protects you from tampered or corrupted binaries. | | C | Optionally extracts the installer (if it’s a zip) and launches the setup wizard automatically. | Saves a few clicks for repeat installations or for tech‑support labs. | | D | Writes a small log entry (date, version, file size, hash) to a local text file. | Gives you an audit trail for compliance or troubleshooting. | mototrbo cps 20 version 226 download free
