[Galaxy S II Q&A, Help & Troubleshooting] chrysilis:
I am unable to flash CM7 from http://xdaforums.com/showthread.php?t=1112916 nor use adyscorpius' instructions to correct the error at http://xdaforums.com/showpost.php?p=15787275&postcount=455

My recovery.log is below, I did two things, restore my nandroid backup so that I would be able to boot and get the log and then reattempt the install of CM7. The main part being that my phone is the GT-I9100T and therefore does not match what CM7 is expecting. Any help would be much appreciated :)
