[Q] HTC HD2 Won't Boot - glitched boot logo too
Recently my HD2 has been acting up a little, it's running android (I've basically followed and installed everything on htchd2android.com/how-to/how-to-install-android-on-htc-hd2-android-4-0-4/), and yesterday would just show the green HTC logo for a second before turning off whenever I tried to boot it up.
I tried taking out the battery and sd card, put it back in to boot up, but this time the screen flashed yellow and white and went all glitchy for a few seconds, and ever since when I try to boot it it shows a glitched HTC logo and stays like that indefinitely.
(You can see what the screen looks like currently at i.imgur.com/42kYqkl.jpg)
I've tried reinstalling the custom rom, everything bar a factory reset (which will be my last resort), but really I just want to know what's caused or causing the problem.
Any advice appreciated!
