3GS 4.3.1 on 6.15. Want to restore to factory

[andrew5826]

hey i have a 3gs FW 4.3.1 BB 6.15. i'm not sure if its new bootrom or old bootrom but the serial num is 880270893NS.
everything is working but i want to restore to factory settings so do i need to restore with a custom firmware? is there a way to restore without having cydia on it? does anybody have a custom firmware that will work on my 3gs without installing cydia?
Thanks

Because you have the iPad baseband, you can't restore it to factory setting. Baseband can't be downgrade.

When you installed 06.15, you read the warning saying that you will never be able to install stock FW again until a higher BB than 06.15 comes out, right?

The closest you can come is to create a custom FW that does not include Cydia.

but will a custom firmware work?

I think linking to them here would break site rules, you need to Google for it.

Both snowbreeze and pwnage automatically install cydia.
