Week 46+ iPhones will be able to be unlocked once a baseband update comes out.
The new bootloader needs a newer version then the current fw to validate the secpack. Basically iEraser won't work until an update comes out. At that point DO NOT UPDATE. You will be able to iEraser and then hardware unlock with the new secpack.
It all comes down to this:
new(A00086A0): BLS badversion ; secpackver<=mainfwver
old(A0000574): BCC badversion ; secpackver<mainfwver
One equals sign can make a big difference
Also nor dumpers will never work with this bootloader. The read command needs a development certificate. We believe a variant of the anySim exploit may still be present in this bootloader, but we need to wait for a newer secpack to test it. There may be a way around this, look for an exploit.
Thanks to pspsully for giving me a new bootloader iPhone to play with, ta_mobile for getting us the bootloader dump, and gray for continuing to reverse.
