I have an iPhone 4 that was jailbroken with Evasi0n. After installing Acid Siri from Cydia and rebooting, the device is now stuck on the Apple logo. The screen dims after a few minutes, restarts, and returns to the logo. I have already tried entering safe mode with the volume up button, searching for files with iFunBox, and restoring with Redsn0w without success. How can I fix this?

To fix an iPhone stuck on the Apple logo, start by attempting a forced restart. For older models like the iPhone 4, press and hold both the Home button and the Power button until the screen goes black and the Apple logo reappears. If the issue was caused by a jailbreak tweak like Acid Siri, try booting into No Substrate Mode by holding the Volume Up button while the device is booting. If successful, open Cydia and uninstall the problematic tweak. If these steps do not work, you must put your iPhone into DFU mode and restore it using iTunes or Finder on a computer. Note that restoring will erase all data on the device, so you should only proceed if you have a backup available.

The most effective solution is to put your iPhone into DFU mode and restore it to the latest firmware using iTunes. Please be aware that this process will erase all data on your device, so ensure you have a backup before proceeding. Alternatively, if you can successfully boot into safe mode or No Substrate Mode by holding the volume up button during startup, you can uninstall or deactivate the Acid Siri addon in Cydia or MobileSubstrate to resolve the conflict.
