So I was jailbroken on jailbreakme.com 3.0 on my Verizon iPhone running 4.2.8. I then started theming the phone and the carrier logo but after a reboot I lost 3G. Couldn't find anyway of fixing so had to restore. I have tried numerous times to downgrade after having to restore iPhone. Everytime I try I get error 1013 or 20 and can't get out of recovery. I even tried kicking out of recovery with tiny umbrella. Anyone else having problems downgrading with SHSH blobs saved on Verizon iPhone? Any ideas? I really want to get back to my jailbreak. I have followed all the directions on YouTube and some of the other sites and edited the host file but keep coming up with the same errors. Please help!
