Yeah weird... I was comparing the data fix files with a file comparison program a while ago.... they are basically the same css, build.prop, and i forget what else....except for different device models, country codes, mobile network codes, few tweaks here and there.... I remember seeing the line that could be changed to display something else besides DatFix in the about section of settings. Not sure about about baseband....should check it out.
I'm good whenever I flash any of the note 4 or note edge roms...echoes, hyper, kyubi, myarom, etc...Basically have tried them all thanks to the R23 915F kernel and the datafix. Few like the 915KSL or whatever and the exynos I cant boot...64 bit cpu I guess. Oh but I will say that my issues with a few of the rooms has been over heating, major battery drains, wakelocks!!! Nothing like that when I flash Teks rom. It's like....do I care for an s6 launcher or theme store that much??? LOL....nah...I'll be fine with Tek's great rom and and Nova.
