Dumb question but, did you follow what the logs themselves suggest? That you clear the iPhone's Bluetooth cache by going to Settings -> Bluetooth -> Off and then On? Using Control Panel does not work, because it doesn't turn Bluetooth off but just stop advertising instead.

All done, it doesn't work

Well... looks like your device does not support Legacy or Secure DFU or the UUID aren't standard. Using the UuidHelper it is possible to change the service UUIDs if necessary.
