I was not able to get Button Remapper to work, but I found out how to manually set the big button to home.
I used Root Explorer to copy the file /system/usr/keylayout/gpio-keys.kl out to another place. I edited this file with a text editor and replaced the line:
Code:
key 28 DPAD_CENTER WAKE
with the line:
Using Root Explorer, I went back to the /system/usr/keylayout folder, mounted it read/write, and copied in the new version of the gpio-keys.kl file. Then I rebooted the T68.
On reboot, the big front key now acts like the Home key.
P.S I've had my T68 Lynx for 2 days now, it's all working fine and I've not had any reboots or screen calibration issues.
