Tenorshare ReiBoot is a computer-based recovery utility for an iPhone or iPad that cannot start, update, or leave a recovery screen normally. The device connects by USB, and Tenorshare ReiBoot can place it into recovery mode, take it out again, or reinstall matching system firmware through a repair workflow. It works on the operating system state; it does not recover deleted personal files or repair a failed battery, port, screen, or storage chip.
Recovery mode first
Entering recovery mode gives the computer a controlled route to communicate with a device that will not reach its ordinary home screen. Tenorshare ReiBoot can trigger that mode without relying on the exact physical-button sequence. Exiting recovery mode can also restart a device that became stuck there after an interrupted update.
The free access is narrower than the whole product. Entering recovery mode is available without a registration code, while free exits are limited. Repairing the installed system requires the repair functions. A successful exit also does not prove that the original fault has gone; a boot loop may return if the system installation remains damaged.
Standard repair
Standard Repair aims to reinstall the required system components without erasing user data. Tenorshare ReiBoot first detects the connected model, then downloads the matching firmware package. A local firmware file can be imported when it has already been downloaded. The package must match the device, and a mismatch stops the repair rather than substituting a different build.
The firmware download is large, roughly several gigabytes, so the computer needs enough free storage and a stable connection. The phone also needs sufficient free device space, and the official troubleshooting steps call for an unlocked device when Standard Repair is expected to preserve data. An original or dependable USB cable matters because disconnecting during firmware work can interrupt the operation.
Standard Repair does not guarantee that every device will start. It addresses software faults such as a frozen Apple logo, repeated restarts, a black screen caused by iOS, or a failed system update. Tenorshare ReiBoot cannot correct physical damage, and a device that the computer never detects may need recovery or DFU mode before repair can begin.
Deep repair erases
Deep Repair is the destructive fallback when Standard Repair fails or the device state is more severe. It writes the system through a deeper reset path and erases data and settings. Tenorshare ReiBoot displays that consequence before the operation, but the warning does not create a backup. If the phone still works well enough to back up, that copy must be made before Deep Repair starts.
Low free space can force this decision. The official troubleshooting guidance states that Standard Repair needs more than a small reserve of free device storage; when the phone cannot be cleaned and falls below that threshold, Deep Repair may be the remaining route. That makes storage preparation part of recovery, not an optional cleanup after it.
Firmware and cables
If the built-in firmware download fails, Tenorshare ReiBoot can copy the address for a browser download and then import the finished package. Changing the firmware folder also helps when the default disk lacks space. A partial download, the wrong device package, or a nearly full computer disk will block repair even if the phone connection is stable.
The device should remain connected until it restarts and Tenorshare ReiBoot reports completion. Moving a laptop, using a loose hub, or letting the computer sleep introduces avoidable failure points. If repeated software repairs finish but the same symptom returns, the remaining cause may sit outside the operating system and require hardware diagnosis.
