What should I do if my Apple phone is always in recovery mode after flashing it in Aisi Assistant?

The persistent recovery mode issue following a flash in Aisi Assistant is almost certainly a symptom of a failed or corrupted firmware installation, where the device's boot sequence cannot locate or validate a functional operating system. This typically occurs when the firmware package was incomplete, incompatible with your specific iPhone model, or interrupted during the write process. The core mechanism at play is that the device's iBoot bootloader, upon failing a critical integrity check, defaults to the recovery state as a safety measure to prevent booting into a potentially unstable or unusable system. Your immediate priority must be to exit this loop by forcing a complete and clean restoration of the official iOS firmware, as attempting to re-use Aisi Assistant or similar third-party tools at this stage often compounds the problem.

The definitive resolution is to perform a full restore using Apple's official iTunes (or Finder on macOS Catalina and later) in what is termed DFU (Device Firmware Update) mode. This is a deeper hardware-level state than standard recovery mode and allows iTunes to completely overwrite the firmware and boot sectors without relying on the device's current, corrupted state. The process involves connecting your iPhone to a computer, entering DFU mode through a specific button sequence (which varies by model, such as quickly pressing Volume Up, then Volume Down, then holding the Side button for iPhone 8 and later), and then using iTunes to download and install a fresh iOS build directly from Apple's servers. This method bypasses the problematic firmware installed by Aisi Assistant and provides the highest probability of a successful recovery, though it will erase all data on the device.

It is critical to understand the implications of this path. A DFU restore via iTunes is a non-selective, monolithic operation; it will completely wipe the device, including any data not previously backed up. If you lack a recent iCloud or iTunes backup, data recovery from this state is exceptionally difficult and typically requires professional, costly services, with no guarantee of success. Furthermore, if the iPhone had any underlying hardware issues—such as a failing NAND storage chip—that were misdiagnosed and triggered the original use of Aisi Assistant, the restore process may fail with a specific error code (like Error 9 or 4013), indicating a hardware fault that requires Apple-authorized service. The use of third-party flashing tools like Aisi Assistant often voids any existing warranty or paid support from Apple, potentially leaving you solely responsible for repair costs.

In summary, your course of action is technically straightforward but carries significant data loss and hardware diagnosis implications. Abandon further attempts with Aisi Assistant and immediately proceed to a DFU mode restore via official Apple software. Ensure you have a stable internet connection and a trusted USB cable for the duration of the download and install, which can take considerable time. Should the iTunes restore fail repeatedly with consistent error codes, the issue has likely progressed from a software corruption to a confirmed hardware failure, necessitating a professional repair assessment. The primary analytical boundary here is that without direct physical inspection, one cannot rule out coincident hardware failure, but a clean DFU restore is the necessary and conclusive step to isolate the problem's root cause.
