SD400 & firmware 101c

I bought an old SD400 with the intention of sending it up on a high-altitude balloon this weekend doing time-lapse photos. Unfortunately, now that it's arrived, it has 101c firmware on it, and the 101b firmware just hangs (unsurprisingly, I guess). Does anyone happen to have a 101c version squirreled away somewhere, or, alternatively, a way to downgrade to 101b?

The camera is old enough that the serial number has worn away, so I can't download the upgrader from the Canon site to see if it allows downgrades.

Hello & welcome, dichro !

I bought an old SD400 ... it has 101c firmware on it, and the 101b firmware just hangs
Can you can dump & upload your fw, like described here: http://chdk.setepontos.com/index.php/topic,2468.msg31055.html#msg31055 ?
--> Note: for the the SD400, the VxWorks option (button) is used (not NewDryOS) !

I guess this won't work, AFAIK the available SD400 fw update is a 1.01b firmware...
The ixus50 / sd400 fw update from Canon is available from this wikia link: http://chdk.wikia.com/wiki/Official_Canon_firmware_updates#PowerShot_S.2C_SD.2C_IXUS.2C_IXY_etc.
(SD400, both files are self-extracting zip archives with identical files, there's a readme text file included)

The official Canon site is here: http://web.canon.jp/imaging/pssd400/frm-e.html
As mentioned on the SD400 wikia page, you can use serial #0013042373 to enter the dl section...

Sorry for the delay! We went ahead and launched just running this camera to record video, which worked surprisingly well:

But now that we have another launch coming up, I finally found time to work out the dumper, and the firmware image is now up at:

Hope I got the download procedure right :P Is 8MB about the right size?

Added the Ixus50_SD400 1.01C dump from this post (8MB, from dichro, dumped with CT/udumper) to the drop.io - chdkdumps2 backup archive.

Thx to the 'dumpers' & uploaders !
