My Aurora is now working perfectly again. I have some theories as to why it was broken and why it's working now, but I'm still not certain of any of it. Here is my long story, maybe it will help you....
I received my V3 Aurora, and I used it for roughly 4 days without problems.
Toward the end of those 4 days, I used SetCPU to overclock and underclock the tablet based on profiles.
I found that if you overclock just a little too far, WiFi will sometimes die on you.
I didn't realize my Aurora had come with a screen protector, but it did and it was installed for about two weeks. It's fairly difficult to remove and I thought I might be damaging the unit when I removed it.
After the, roughly, 4 days of working properly, the unit started having random touches. I tried several different ROM's including custom and stock ones and I formatted everything I could every time. Sometimes I thought it was fixed, but in a little while, the problem always came back. I setup the unit to show touches and not sleep while on AC power and used a free app off of the market called "Multi-touch Benchmark Test" which would tell me if any touches had occured. Some of the touches may not have been that noticeable because they didn't land on icons, buttons, etc, but that app will catch them all.
After a couple weeks, I realized that I could actually remove the screen protector despite how well it was adhered to the screen. However, it did not help. I power cycled, tried different ROMs again, etc... I even tried lightly twisting, and bending the unit as well as pushing slightly hard on different points of the display. Nothing worked. It didn't seem to make it any better or worse.
I finally decided it was probably a hardware problem and was going to exchange it for a new one so I left the unit OFF and unplugged for two days.
Before boxing it back up to send it back to it's homeland of China, I turned it on just for fun. It's been running 1.5 days now without any problems. I have power cycled it about 5 times, I've run the same touch test, I've run ShadowGun, Even tried two different ROMs and it will not fail again (so far).
Here are my theories (I have a lot of theories, sometimes they are right, usually not, but thats how we figure things out, please feel free to contribute if you have other theories):
Not Screen Protector: It could have something to do with the screen protector, but I don't think so. I'm an Electrical Engineer and it seems highly unlikely that static could build up but not be discharged to the users hand. Also, the fact that I removed the screen protector and it didn't change anything leads me to believe it was not related.
Overclocking or Underclocking: It could be a timing issue caused by changing the clock rate that puts the touch IC in a bad state. You would think that turning the unit off would reset it, but maybe there is enough capacitance to keep these low-power devices in a bad state through power cycling. Maybe leaving it off for a few days allowed the voltage to drain off. I know it sounds crazy, but I've actually seen something similar to this in a low-power design I was working on.
Intermittent: It could be an intermittent hardware problem that comes and goes. Maybe it will stop working again. I hope not, but I'm going to leave it with a pretty simple setup for several days to see if it stays well behaved.
If you want to try any of this, I suggest you wipe user data, format the system partition, install a fresh ROM, power the system off. Do not connect it to power and let it sit for a few days.
Good Luck
