fujifilm finepix s series

Hi,
my name is Giancarlo and this is my first post here. I just bought a Fujifilm Finepix s2700HD and was utterly disappointed by the limitated-on-purpose software accompanying an otherwise great camera. So i started digging for solutions.
Now: i know that you're not so interested in starting development of a whole new hack kit for fujifilm from scratch, but luckily i'm a professional developer that sometimes does lo-level for fun, so i offer myself to experiment a little bit if proper starting directions are given.
There are many reasons to help me doing this:
1) Finepix hardware is good and they're probably the cheapest cameras on the market among the bridge category
2) the exact same firmware is often shared across a great number of different camera models (e.g. the firmware for my camera is directly installable in the following models: S2500HD / S2550HD / S2600HD / S2700HD / S1800 / S1850 / S1880 / S1900 / S1600 / S1700 / S1730 / S1770 / S1780), so great compatibility could possibly be achieved with little effort
3) I already downloaded a firmware update and looked inside it with an hex editor and found lots of references to scripts with .srt extension that contain basic like commands (yes, the file doesn't appear to be encrypted)
4) i'm not so mad to desire a whole new firmware... for me, just an hack to be able to save RAW data would be a great improvement to start with

So, if someone wants to take a look, the firmware update file is dowloadable here ( http://www.fujifilm.com/support/digital_cameras/software/firmware/s/finepix_s2500hd/fupd.html ) after conditions somewhere in the middle of the page are accepted. Don't be fooled: only the DAT file is needed.

Any advice? For instance... is that DAT file only containing the new firmware to be written by the exsisting camera software, or it is the executable that actively flashes the internal memory? can you recognize a structure usually connected with a certain architecture in the photography world? Is the starting magic number "RHIR" helping any of you recognizing the format? Wich tools can i use to extract/disassemble?

Many thanks in advance.

UPDATE: maybe there's no need to hack anything, because i discovered the presence of a so-called "HIDDEN MENU" that gives access to various debug, development and calibration features. Notably, it gives the chance to switch to manual focus and to save RAW files when capturing. Too bad i have not discovered how to access this menu, yet: i can only see the menu title and all the functions labels inside the firmware update image.
So, i'm calling for help to anyone that happens to own a finepix to try different combinations of keys while turning on the camera to help discover the access to this hidden menu - or - to take a look into the firmware update file - or - to dig deeper in the internet for service papers.

PS: in the firmware i saw that they're using (un)lock files... that is, for crytical operations a file with a given name has to be present on SD in order for the operation to succeed. From my brief analysis, "A:\" appears to be the internal memory, while "B:\" seems to be the SD card.... maybe some further reading of the strings in the FW package could make this mechanism more clear.

PS 2: in my experience nothing went wrong (it would be silly for a camera to hang if mistakenly turned on with the wrong key pressed down), but i experienced a small malfunctioning possibly unrelated to my attempts. A configuration reset immediately solved the issue.

While i understand that this could be a little bit out of topic in a development board, i think mantainers will understand my willingness to post it here anyways. Nevertheless, the discovery of the hidden menu could lead to advances in the development of a possible hack.

Ok, sorry to bump this over and over, but i think this is a nice place to report updates. I'm sorta giving up trying codes by hand... i would like to try disassembling code to find there how to access secret menu. I understand that i should use IDA to disassemble binaries, but the question is: how to extract single binaries from the whole .DAT package? If anyone with some experience could give me and advice...
thanks in advance.

Hi, just to give you an heads up. I have bought an ultra cheap AV200. They only costs 50 euro's here now. It is a pretty camera with 720p recording. The biggest problem I have with this camera is that it lacks a manual focus, aperture/shutter setting and records 720p is such conservative mode that is probably only choosen to support any slow SD card on the market.

I am surprised that you found an HIDDEN MENU. That indeed opens possibilities. I have downloaded the 1.01 firmware for my camera. I hope there is some clue in there.

Next to that, the foundation I participate in contacted Fujifilm The Netherlands, if there is any possibility to kickstart a CHDK/Magic Lantern project, just to have competition with Canon. They understood our proposal and passed on the question to Fujifilm Germany. I'll keep the updates posted.

As was pointed out in the first post. It is easy to see there is a HIDDEN MENU somewhere. And a lot inside the camera is scripted. The entire fireware of the Fujifilm AV200 AV205 seems to be unencrypted.

This is just plain-text; The firmware might actually some sort of filesystem.

Hi, I've been reading all the post and I'll like to contribute somehow to the development of this. I own a S2950 and I also think that is really limited to what it can really do. I kinda-know which tools to use but I see that you have some advantage. Which tools are you using or recommend me to start to work?

Grettings for all your effort.

Hello all. I'm using FujiFilm HS20EXR and I'd like to help you.
Skinkie, can you tell me, what soft did you use to decompile or look through .dat files from firmware to get this function's headers?

How to access scripting:

1. Create "Batch" folder on SD Card
2. Create BatchScripts.txt file in "Batch" folder
3. Open BatchScripts.txt with notepad and write any word there, e. g. "test" (without "").
4. Create a file named the same as the word in "BatchScripts.txt", with .srt extension (e.g. test.srt).
5. All BASIC codes goes to this file (e.g. test.srt)
6. Create a 1:1 copy of your file (test.srt) with the same name, but change the extension to .pat (test.pat)
7. Turn your camera on


Quote
Validating log file of B:\Batch\test.srt:
    Matched.
Max memory allocated for this batch: 17680 bytes

@alex:
Just simply open fpupdate.dat with hex editor or notepad++

@lionking, when I opened it with np++, I got a list of symbols. Without code or something readeble. (I'm working with HS20EXR)

Interesting, but when I opened your fpupdate file, I got that list of strange symbols too. Looks like I didn't have some symbols.
