Newbie here but not to hobby, need some info 5100,5101

[intheb0x]

Can anyone help?
I don't have a jtag but need to find a way to load the certs onto this modem.
Can I use ipfull?
My 5101 is up and running but my 5100 is still down, with bpi disabled it connects and goes online but no Internet access with just bpi enabled it also goes online and says it authorized but still no Internet, and with bpi+ enables it doesn't even connect the online light just flashes.
I have the cert files (4or5 of them) ready to load but I don't know how.

I seen there some telnet command format editing certs, I that something I could use?

I'm at a stand still until I figure out how to load the files onto the modem because mac cloning is no longer working here as of my first post.

Thanks
