But I'm looking at the Skydragon mixed version, and it has an entirely different method of installing for S-ON phones (flashing new boot.img, etc.) None of those steps is particularly scary to me, but I'm wondering WHY they're needed.
What's with the new boot img? Does it have something to do with getting GPE roms or is it just what the guys at Skydragon have set up?
What happens if I just flash it like "normal" roms (pretending that I'm s-off and flashing from recovery)?
Right now I'm on an AOSP rom. Assuming I go through the extended procedure for installing skydragon S-on, will I be able to move back from Skydragon to AOSP again, if I want to?
Thanks for bearing with me.
S-ON = Security ON; S-OFF = Security OFF
some devices of HTC with S-ON does not support flashing boot partition (boot.img file) via recovery and you have to flash them in unlocked bootloader , fastboot mode, like HTC One X (S-ON) and vice versa
S-OFF gives you full access to modify all partitions (boot, radio, etc), unlike S-ON
now on our HTC One S-ON, there is no restriction to modify boot partition, in other words, you can flash every ROM without worrying about the boot.img file seperatly
(because it's already in the ROM zip file and will be flashed along with the ROM)
as for the SkyDragon ROM mention, the text is from his One Xs' ROM so don't worry
i know this sounds confusing, sorry for my bad English
