good to hear its doable on harmonia rom. im harmonia 3.17, bootloader unlocked, twrp 1.1.1... i might try it tonight ..
Just achieved S-off, now will share the experience. Don't let term Stock RUU scare u as it is in bold and underlined, in Step 2 of bear guide. I still don't know what it means. i feel like its just a way to return to bone stock. Just follow the bear guide, the "trickiest" part was the wire thing. I actually poked the wrong hole for a good two mins ... then realized it was wrong.. Switched to the right hole then controlbear continued and told me it failed. Program exited and i just started it back up again and this time when asked to do wire trick i only had to do it like once. rebooting was kinda weird .. at first it wouldnt boot past Harmonia loading screen, i simply just turned off phone and restarted. Once booted up i went and pasted PG86IMG to the root of sd and booted back in bootloader and flashed the update by pressing Y when prompted. The sd card used is still fine.
