Kx 1.01 firmware checksums are different

interestingly enough, the checksums for the Kx's version 1.01 firmware are different between the version from pentax.jp and pentax colorado

any reason for this?

It's strange both mine look the same - in-line with your US version.

tnx

That's the advantage of the checksum dump I pasted - one can see the directory the file was in - because by Dec/6 I knew I would have a version from Japan and one from US I was very careful to distinguish and separate the two.

I went back to re-examine the downloaded files.

The Japan file was named - kx_e101w.EXE
The US file was named - 63395216872278534951591kx_e101w.exe

so it was not that difficult to distinguish between the two downloaded files -
just to be sure I re-expanded my original Japan file and re-ran the checksum -

As you see my original Japan file is the same as the current US file (yes, I also just downloaded the US version again and check that too)

vincent,

thanks. i'll have to check up on what i've downloaded.

EDIT: i noticed you also found the "other" firmware from the japan site with the MD5 checksum of

C:\download\pentax\japan1\FWDC206B.BIN
11010048 bytes

MD5: 2c5376d258e834d0c1d445a2d8c34efc

so i'm not sure which is the newer firmware. i used the one from the japan site, because at that time of announcement, that was the only site that had it.

which version did you use for your kx ?


EDIT: i compared both binaries in UltraCompare and found quite a bit of differences between the 2 firmwares. they do have the same size and date though.


tnx

jordan

I used the one I downloaded from the US site - thinking that if there even was a slight chance of anything going wrong - I may have better recourse if I used the "official US" version - not that I saw any difference at least when I compared file sizes.

there are significant differences in the f/w which makes me wonder if there are differences in the h/w for bodies distributed in japan vs us.

apparently the f/w from pentax canada matches the one from the US

this is just one page snippet of differences.

welcome to the wonderful land of Pentax' secret firmware releases...
They usually do several little, unnanouced updates with the same version/timestamp/filesize, before delivering a new version!

So cheer up, this means there is a new firmware coming!

i wish there was an update, however, these 2 firmware versions were announced a few days apart.

the version from japan was available days from the version here in the US.

a little concern is that the f/w are different.

oh, well. we'll see. will have to keep on monitoring the firmwares from both sites.

the exif says it's version 1.01.00.05

EDIT:

the current FW from pentax.jp exif says 1.01.00.07.
so i guess the FW in jp was updated since i downloaded it 12/5/2009.

I think the MD5 checksums look the same?

Copy and paste these in NotePad one directly under the other they seem identical to me (unless all these characters have made me cross-eyed)

I have the US version on my K-x, using PhotoMe I get FW version 1.01.00.05 -



My "original" Japan FW was downloaded on Dec/3/2009 4:14AM -
which was earlier than your download on Dec/5-
so perhaps Pentax.jp "updated" the FW to version 1.01.00.07
sometime between my and your downloads?
and perhaps that's why your opening post Japan version was different to the US, and my (earlier) Japan version?

You guys do realize that 2 different files will give you a different checksums, right? Of course they wont be the same as there are language differences in the firmwares.

Some companies also make a universal or international version of firmwares which would also have a different file size/checksum.

joe,

hi. i realize 2 different files will give 2 different checksums.
I was checking out the latest FW for the kx on the japan site and the checksum is different from the one from the US and Canada AND also different from the originally posted (from 12/3/2009) fw.

the exif information is also different (newer) suggesting that the FW in the japan site has been updated.

tnx

it appears the latest KX FW from usa has now been updated to reflect the version from japan.


they now have the same checksum

MD5: 2c5376d258e834d0c1d445a2d8c34efc

sounds like the "beach boys"

"something tells me I'm in to something good" for the Kx
