Problem with my 4.2.1 3G

Hey guys, at one point I considered myself decent at this stuff but its been about a year since I messed around with anything and now I got a larger phone and tried to switch over and heres what happened.

I was running 4.2.1 jailbroken and unlocked on the new phone to test it out, its a 3G.

I stupidly reset it thru the settings. I have the 6.15 baseband and Ive its now stuck on the apple logo. Ive tried resoring thru Itunes with custom firmware, regular firmware, Ive tried re jailbreaking thur redsnow. I did this before awhile back and cannot remember the procedure to fix it.

I can get it into DFU and get it to START the jailbreak but it stops at "patching kernal" ....

Someone refresh my memory..... HELP!

 

Ive tried searching on the topic on Iclarified but can't seem to find a specific tutorial..?
