I've got a newer firmware: ver.req - I tried switching the output format to PAL and it made no difference. I have firmware GM1.00C:
Canon PowerShot A1100 IS P-ID:31C3 NT D
FirmWare Ver GM1.00C NoError Apr 24 2009 19:12:45
After another press, I have 4.011:
Adj Ver.004.011
The third and fourth screens are the same as everyone else's:
IS Firm Ver. 2.11 IS Param Ver. 2.07
Driver Info: 0x00000000
With vers.req I get:
Canon PowerShot A1100 IS P-ID:31C3 NT D
FirmWare Ver GM1.00C NoError Apr 24 2009 19:12:45
Second press (4.011):
Adj Ver.004.011
Third press (shoot count):
Adj Ver.004.011 Total shoot: 2 Zoom retry count: 0 Mecha Condition: 0x00000000
Fourth press:
Driver Info: 0x00000000

I'm trying to install udumper with this shell script:

if ! mount >/dev/null 2>&1; then

mount

echo "Please format a FAT-16 partition and name it UD_something"
