just wanted to let all suffers know the HTC ROM Update at
ROM Upgrade for HTC Hero_2.73.405.5
fixed all these issues for me:
Notification LED stays dark during charging.
Buttons and Trackball lights are dead.
Audio Jack is dead.
I did a backup of my data first using MyBackup.
Not all programs were restored from /sdcard with MyBackup.
Most notably restore of my 1352 contacts crashed in the middle, but I fetched them again via HTC sync which is a lot faster than MyBackup restore from /sdcard.
HTH someone,
Adrian
