Have a galaxy note sgh-i717 ATT. Was rooted and custom rom, but then I used QPST to install .qcn file to phone. Now on any rom custom or Stock it will boot loop over and over again. Cannot get into phone to try and change back the .qcn file. Which turned out to be the wrong one. It was called 337_aws.qcn. I have saved the original but havn't figured out how to restore it to phone if indeed that is the problem. The boot loop started when I did this. I have tried many different roms custom and stock with no luck to stop the boot loop. It will boot all the way till it starts reading sd card an such, then reboots. Any advice to get this to stop. Have tried kies, will not connect. I have the right drivers and such. Have read other posts on this problem and tried them all. No luck
