Hi, im tired of waiting for Lollipop on my note 4, i have N910HXXU1ANK5 and i was thinking about flashing the other country's firmware, how much is the risk of bricking my device? i pad 800$ for this and im extremely scared! its so much compared to my previous nexus 4 :) on my old nexus 4 is was like fastboot unlock and tada! its a bit harder in here and i bricked my old n7000 so i rather be careful this time!
Generally how much is the risk of bricking a note 4! what could cause it! i know in general its wrong firmware but like the old n7000 factory reset on ics would kill it and which it did :( is there anything special like that with the note 4? just be sure too check rom versions?
and what should i do to install 910C on my 910H? what happens if i do something wrong?(soft or hardbrick?)
sorry if this thread sounds stupid, but im going to be 100% sure before i do this as i paid my whole life savings on this :D
thanks!
