I bought my desire z from hong kong and flashed cyanogenmod. I notice keys are mapping wrong and "Home / Menu / Back / Search" key got no effect.
There are some difference between desire Z and G2's keypad.
I pushed keypad files from stock rom, problem solved.
Here is a simple signed update for the keypad files.
update-vision-keypad-for-desirez-signed-v2.zip (172.06 KB)
v2 with AnyDone's fix for NOR keypad, see here.
1. Clockwork Recovery installed.
2. CyanogenMod-6.1 for Vision installed.
1. install update-vision-keypad-for-desirez-signed.zip by recovery.
Enjoy! Thanks Cyanogen for the great ROM!
