Both of them are from almost a year ago and not specific to HTC One. The instructions on one of them is for 4.4+ ROMs so it seems like it will work but max DPI is xHDPI which I'm getting mixed answers on whether our phone is xxHDPI or xHDPI which I'm guessing will make a difference.
Anyway I use HALO all the time in my AOSP ROMS and very few of them allow you to change colors and none of them let you use a custom icon. Would be awesome if someone made flashable zips with different icons and I would do it if I knew how (directions seem simple enough but I don't know about compatibility isses). Any info on this would be appreciated.
