SSH it in.
Upload the .deb file to /var/root/.
Open Mobile Terminal
Type "su" and hit return when you first launch terminal then it will ask for a password
type "alpine" then tap return
type cd ~ ; dpkg -i «filename.deb», where you have to replace «filename.deb» with the file name of the uploaded file (without the guillemets). Also pay attention as case matters, one is a tilda, not a comma
Respring your device.
Thanks for the upload and instructions. Unfortunately, my Winterboard still brings up Safe Mode. Did you test this on a 3Gs with 3.1? I rechecked Mobile Substrate in Cydia and it indeed says it's 0.9.3043-1. So I'm perplexed what the problem is. I don't even have anything active in Winterboard when I start it up so it can't be any of my themes.
still having problems after 3.1.2 upgrade.
but i saw this and just want to share.... however it didnt work for me.
it might be u have an old version of Telesphoreo source. There is a quick fix for that.
Just go to Cydia, tap the Sources, Edit and add: apt.saurik.com/cydia-3.7
