Good to know

Quick answers. For anything else, reach us on Telegram, we answer.

Is it really free, with no account?
Yes. Download it, open it, use it. There is no login, no sign-up, and no cost, now or later.
Why give it away for free?
Because we were helped when we started, and a stuck or locked phone should not cost someone a day's pay to fix. We put our experience into this tool so people anywhere can repair what they own.
Which devices and platforms are supported?
Android and iOS phones, over ADB and fastboot with dedicated Xiaomi and Samsung tools, and the app runs on Windows 10 and 11. We keep adding more.
Will I need to register my device?
Not for the basic tools. As we add advanced, sensitive features, some may ask you to register a device, for example by IMEI, serial number or ECID, and authorize it through our secure server. This keeps the platform safe and stops abuse, and we always tell you clearly first.
How do I know my download is safe?
Every release is published with its SHA-256 fingerprint. The app's Verify Build button checks your copy against our records in one click, so a tampered copy is easy to spot.
Does it collect my data?
It runs locally on your PC. It only contacts our server to check updates, verify a build, and authorize certain tools, and that traffic is encrypted. See our Privacy Policy.
Can I use it in my repair shop?
Yes, on your own devices or ones the owner has authorized you to service. Please read our Terms of Service, use must always be lawful.
