I have searched and can't find a 1.01b firmware update for my SD700 IS 1.01a camera. Can someone tell me if I'm just out of luck and cannot use CHDK? Or if there is some work-around that will allow me to use it?

Many thanks from a grateful noob.

Sorry to bump this, but I figure I can't possibly be the only one still looking for an answer. I've got an SD700 IS 1.01a camera like 5x5 here, and I'm surprised that there's no releases for that firmware.

What help can I provide to get this made for 1.01a?

Please dump that firmware via the universal dumper and post the result here.

My IXUS800(SD700) 1.01a does boot with the 1.01b CHDK - but I have not yet tested whether 100% functionality is available.

I tried the 1.01b CHDK, but there must be some little difference between your 1.01a and mine.
Regardless, I managed to dump the firmware.
Thanks mkmenuts.

I've looked in the dump and compared with 1.01b. The differences are only in textual strings:

> Comparing files 101A/PRIMARY.BIN and 101B/PRIMARY.BIN
0000A56C: 20 32 - date of build
0000A56D: 36 30 - // - // -
0000A580: 32 30 - time of build
0000A581: 30 39 - // - // -
0000A583: 35 32 - // - // -
0000A584: 34 31 - // - // -
0000A586: 30 34 - // - // -
0000A587: 38 35 - // - // -
0000A5AC: 30 31 - 1.00 -> 1.01 (this is the fix for that this version was released

)
0000A5DB: 41 42 - A -> B
00038626: 41 42 - A -> B

So, it fully compatible with CHDK for 1.01b.
(Today is lucky day. Three cameras: SD1000, SD750 and SD700 have 1.01a and 1.01b firmwares which are compatible.

For the particular model, of course.)

There's quite a number of builds out there, I don't think the Allbest one worked for me. Is there a specific version you'd recommend for me?

HOORAAY! It works! I'm not sure which build of allbest I had grabbed previously (wouldn't give me the chdk banner), but this works marvelously.

Thanks so much!
(now to get it to autoboot)
