that list is mainly for phones that came out before sept 2011 i beleive, in theory all phones after that date are supported and you would just use the other supported phone option
Normally it does work that way. And I was very disappointed that it did not on this phone, as I made the kernel just for that reason.
I think there was an error in the coding where it tells unlock which partitions to remove write protection from. That, or they just wanna make our lives hard for some reason.
Either way, you cannot write to /system while the phone is booted normally without S-Off. Even as root.
