How to Flash iPhone: 3 Methods to Fix Software Issues

Is your iPhone running slow or stuck on the apple logo? Are you experiencing the black screen of death or unable to get out of recovery mode? These issues can be frustrating, but a firmware flash could help you out. By updating or reinstalling the iOS on your iPhone, you can tackle these problems. In this blog post, we’ll show you three methods to get it done.

Method 1: Update Software Wirelessly

The first method to update your iPhone software is wirelessly. Open the settings app and go to general, then software update. If an update is available, go ahead and install it. If your software is already up to date, move on to the next method.

Method 2: Reinstall Software Using iTunes on a Computer

If updating wirelessly doesn’t work, you can reinstall your software using iTunes on a computer. Connect your iPhone to the computer and put it into recovery mode. For iPhone 8 or later, press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button until you see the recovery mode screen. For iPhone 7 or 7 plus, press and hold both the side and volume down button, let it go when you see the recovery mode screen. For iPhone 6s or earlier, press and hold the side and home button until the recovery mode screen shows up.

iTunes will prompt you to update or restore your iPhone. If you want to reinstall the firmware, select update. If you forgot your passcode and want to start over, select restore. Once the firmware is downloaded, iTunes will start updating. This process won’t erase the data on your iPhone.

Method 3: Repair iOS with ReiBoot

If the previous methods don’t work, you can repair the iOS with ReiBoot. The standard repair mode by default will try to solve the problem without data loss. If your phone is not recognized right away, you’ll get step-by-step recovery mode instructions, which covers not only iPhone, but iPad and iPod. You can download the firmware to a location of your choice and start the repair anytime you want. If everything goes well, the issue with your device should be fixed once the process is complete.

In conclusion, these are three methods you can use to fix software issues on your iPhone. Hopefully, one of these methods solves the problem you are facing. Remember, it’s always a good idea to back up your data before attempting any of these methods. Good luck and happy flashing!
