Has anyone used ReiBoot to repair iOS system issues?

If your iphone is freezing or crashing, try follwing steps.

1.Force restart your iPhone first.

• Press Volume Up, then Volume Down, then hold the Power button until you see the Apple logo.

2.Check if your storage is full. (Based on my years of experience using an iPhone 11, this is the main issue.）

• Go to Settings > General > iPhone Storage. If it’s full, clear some space by deleting apps, photos, or other large files.

3.Check if your phone has any hardware damage.

• Have you dropped it recently? If so, you might need to contact Apple Support.

4.See if you’ve installed any third-party apps recently.

• If you have, try deleting them—some apps can cause issues.

As for ReiBoot, it can help you flash your iOS system or factory reset your iOS system, it does work, but still, try the above method first.

Try to free up storage on your phone, that may be the issue. If not, you can update your phone or try ReiBoot. I used it to fix my iPhone stuck on the Apple logo screen—no data loss, worth it! But downloading the firmware took quite some time because my Wi-Fi connection was poor. So you can try it if the freeze happens a lot, maybe fix it before it gets worse.
