Sharing is carring...Unbricked my att E970 using this method.
I want to share something that helped me in restoring my bricked phone last night. I spent 6 hours trying to unbrick my phone trying to use all the techniques on this website but nothing worked for me. Searching and searching the net I found this useful tool that you can download. I've seen something similar for older phones but this definitely worked for my phone. You'll have to find the necessary rom and phone specific dll for your phone but it does work. I've rooted my phone and the process even kept my photos. I haven't had any issues and 4G & wifi working great as before. I hope this info helps others.
