The tool was originally distributed through private GSM forums and paid unlocking services. The “v1.0” floating around on YouTube, Telegram, and file-hosters like MediaFire or Upload.ee is almost always a cracked, modified, or fake version.

Unless you are an experienced GSM technician running the tool inside a sandboxed virtual machine on an isolated network, downloading the v1.0 crack from a random forum is a bad bet. You’re more likely to infect your computer than to successfully check a modern phone’s SIM lock.

Instead, use a free SIM card swap test or pay a small fee for an IMEI-based check from a reputable website. Your personal data and device safety are worth far more than the $3 you’d save.
