I'm total newb in anything related to flashing, installing OS on a phone. Just got some old HD2 from a friend which software seems fckd up. When i turn it on i just get "aMAGLDR v1.13 Build: Feb 1 2011 03:46:07 byCotulla 2011". So i want to install Firefox OS 1.4 or maybe older ver. of Fireofox OS if there is not good one for HD2 to play with that OS. Or if there isn't Firefox OS for HD2 i would go with stock android...what ver? 4.4 would be awesome if there is for HD, or maybe Cyogenmode. Can someone help? I'm totally newb and i need literally every step explained.
