How to remove Yalu102
If you want to remove yalu102 at any point, you will simply need to restore your device to iOS 10.2 in iTunes by manually downloading the iOS 10.2 IPSW, alt-clicking Restore in iTunes, and selecting the IPSW you downloaded.
It is important that you check that iOS is still being signed before doing this. If it is not, you will be forced up date to iOS 10.2+, and you will be stuck. This is only the best way for at most a few more days. Check signing status before you do this.
Once iOS 10.2 is no longer signed, you will need to uninstall all of your Cydia tweaks and apps. Go ahead and delete the yalu102 application from your device entirely. Ensure the trustred profile has gone from Settings > General>Device Management. Reboot your device, put Cydia in a folder and do not touch it. This is really the best you can do when it comes to removing yalu102 from your device.
