Feedback from real i4Tools users.
I run a check report on every second-hand iPhone before buying. Battery cycles and storage type are right there — it saved me from two refurbished units.
My phone was stuck in a white-apple reboot loop. Quick flash brought it back in ten minutes with clear on-screen instructions.
Switching phones used to mean losing photos and chat history. A full backup and restore moved everything over, even the home screen layout.
Answers about installing, connecting and using i4Tools.
All core features are free. Installers from the official site are clean, with no ads and no third-party bundles. Always download from the official source to avoid modified builds.
Firmware comes straight from Apple servers and is verified, and the tool never modifies low-level system data. Turn off Find My iPhone, keep battery above 50%, use the original cable and follow the prompts.
Check the cable (original or MFi), confirm you tapped “Trust This Computer”, make sure the latest iTunes drivers are installed, and try a rear USB port on a desktop PC for stable power.
By default in Documents / i4Tools / Backup, and you can set a custom path in Settings. Selective backups like photos and contacts support preview and partial restore; keep full backups off the system drive.
Click the Apple menu → About This Mac and check whether the chip is Intel or Apple (M-series), then download the matching build. Right-click the installer and choose Open to install.
i4Tools is not on the App Store; anything similar there is a counterfeit. Install the desktop client first, connect your phone by cable, and let the PC push the mobile app to your device.
Windows and Mac, official build, free to download and ready to use.
