Thank you very much for the info ZF_. And special thanks to the effort of the DEV TEAM ! Will do it later. Thanks again.
Error 0xffffffff is likely due to interference from the CommCenter. Please unload it first. I've revised the installation instructions on the wiki.
Note that sometimes it's not enough to do "launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist" ... sometimes you need to follow that by "killall -9 CommCenter" to make sure it's not hanging around.
MuscleNerd or someonelse is there any benefit to upgrade to BL4.6 beside the fact that Apple might check when you return the iphone for service?
Thanks for the writeup on the FB, I like to understand things before doing it. As apparent FB is useless if you are not going to run serial payloads.
Neutered 3.9 and neutered 4.6 allow all the same things...NOR dumping, unsigned basebands, etc. And yes fakeblank now is useful mostly for serial payloads (baseband hackers), now that BootNeuter lets you go up to 4.6 from stock 3.9 (whereas before you had to be fakeblank 3.9 to do that).
Thanks MuscleNerd, good job on everything you've done.
