Hello,

It sounds like you're encountering a serious issue after updating the KernelSU app on your OnePlus Ace 3 running Android 14. The error message you received suggests a problem with the kernel or the system's ability to load it properly. Here are some steps you can take to try and resolve the issue:

  1. Boot into Recovery Mode: First, try to boot your device into recovery mode. This can usually be done by holding down a combination of the power button and volume buttons (the exact combination may vary depending on your device, but it's often power + volume up). Once in recovery mode, you'll have options to perform various system maintenance tasks.
  2. Wipe Cache Partition: In recovery mode, select the option to 'Wipe cache partition'. This can resolve many issues caused by corrupted cache data without affecting your personal data.
  3. Factory Reset: If wiping the cache partition doesn't work, you may need to perform a factory reset. This will erase all data on your device, so make sure you have backed up anything important before doing this. To perform a factory reset, go to 'Backup and reset' > 'Factory data reset' in recovery mode.
  4. Flash Stock Boot Image: If the above steps don't resolve the issue, you may need to flash a stock boot image. This process involves using a custom recovery like TWRP and flashing a stock firmware image for your device. Be cautious with this step, as flashing the wrong image or doing it incorrectly can further damage your device. If you're not comfortable with this process, consider seeking help from someone who is experienced with Android devices.
  5. Seek Professional Help: If you're still unable to resolve the issue, it might be best to seek help from a professional. There may be a more specific problem with your device that requires advanced troubleshooting.

Remember to always back up your data before performing any major system changes. If you have any further questions or need more detailed instructions on any of these steps, feel free to ask. Good luck!
