3e recovery fix

[abreham23]

So i know that there are fixes to the Froyo 3e recovery but they all require you to connect a usb. Since my usb port doesn't work(I found another way to charge my phone and transfer files) is there a way to fix the 3e recovery so that it doesn't go through a signature verification? My goal here is to try and root my captivate.

Thank you!
