Hey all!I ran into some issues with the 7/24 firmware and revved back to 07/18 - now, for some reason, I CANNOT AT ALL get my touchscreen calibrated using the PDN setup app.I've tried a pencil eraser, my finger, my fingernail, I just get through all four taps and it says CALIBRATION FAILED.This is driving me nuts. Any suggestions?

reflash... i had that problem when i flashed 7_24. Even the calibration on the initial boot failed. After I reflashed it was fine.

I had a bad screen setup after flashing to 7/24 and needed calibration. My touches were all registering about half an inch too high. Had a failed calibration attempt, too. I rebooted a few times, and eventually got it set. I then rebooted again, went back into calibration and chose default, and things were normal. It was a pretty frustrating couple of hours or so, to be sure. I've had bad luck a couple of times having a custom calibration vs. choosing default, btw. Ghost-like movements stuck in a loop that are hard to get to stop (even with power-off/rebooting)... so once I get it working, I always go back and choose default calibration, and it's still been fine/fixed and the looping weirdness is gone.

I've had this problem. Try a hard restart - reset button. Then you're stuck with a reflash. I think it may have to do with latency in response to the screen - the processor is backed up and doesn't register the calibration touch because of it.
