I made a mistake in my TCP setting, and made a correction later when I realized the mistake (yes, I saved the option). However, when I reboot my device, the old (mistaken) setting returns.

I've must have saved a new setting several times, but whenever I reboot, the old setting comes back. Since it's an incorrect setting, I have to fix it again.

This is really annoying. Can anybody help?

Which version of BlackBerryOS are you using?

Newer versions of BlackBerryOS might fix this problem...

I'm using OS4.

I've changed the setting by clearing the field and then saving it. I deleted a program that taps on boot-on system, and now it seems to be working.

Thanks
