We’re back from a family trip to Colorado. We drove there and back, because I’m cheap, and I’d always wanted to do a ‘road trip’.
It was a really good experience, getting to see parts of the USA not seen before, and experiencing the change in landscape.
So I have posted the above picture as my new header to remember the trip by.
Will post some pictures once I’ve processed them…
I’ve just updated the online patch tool to v1.4 which brings two picture related changes:
The D7000 already has these as menu options, albeit the NEF files are compressed in a lossless format, so are generally 22MB.
Now we just need someone to doing some “real” testing to workout if it’s worth it.

Thanks to the testing efforts of Brett Dikeman we now have a verified D7000 version of the of the Time Restriction Removal patch.
The FirmwarePatch tool has been updated to v1.2 and supports patching Nikon D3100 & D5100 & D7000 firmware.
[Update 24th April] A web-browser cross platform patch tool is also available.

I have just released a Silverlight based patch tool. Thus it works on both Mac and Windows PC’s
https://simeonpilgrim.com/nikon-patch/nikon-patch.html
It auto-detects the supported firmware models (D5100, D3100, D7000) and shows a list of available changes (current just one for each model).
This will be how I’ll release future versions of patches.
Thanks to the testing efforts of 4cc3ss we now have a verified D3100 version of the Time Restriction Removal patch.

The Nikon Hackers team would like to announce the release of the first hack for the D5100 (also D3100 & D7000): Removing time limit restrictions on video recording.
The web-browser cross platform patch tool
To use:
This should not brick your camera, but if it does I and the other Nikon Hacker team members will not have/take responsibility for any damages or liability. I have this firmware on my camera, and have taken a 25 minute video with it, but result may vary. Also damages that may occur due to camera operation times longer than specified by original manufacturer are your responsibility.
The Nikon Hacker forums is the place for discussing this patch, future patchs, or just to get involved.
We would like to invite any interested developers to help progress the firmware decoding process.
Soon we will be releasing the same patch for D3100 and D7000 camera’s but we have not tested these patches at all, so we are looking for VERY KEEN Alpha testers to try it out these changes. Contact me directly (simeon@simeonpilgrim.com) if you are interested and don’t mind possibly bricking your camera. If you don’t know what bricking means, don’t apply. All three tested and released.
[update] If you apply the patch please report results here or On this Nikon Hackers Forum post
[Update 31/3] v1.1 has been released with support for D3100 camera’s
[Update 2/4] v1.2 has been released with support for D7000 camera’s

I’ve found the memory location of the video recording limit (20 minutes on the D5100) and change it to 1 minute to allow for faster testing.
Here’s a really exciting video where is stops record after 1 minute with no user involvement.
[Update 40 minutes later]
The D3100 10 minute limit has been located, and the D7000 20 minute limit has also been located.
[Update 30th March]
Here’s a screen snap of a 25:59 minute video (1080P 30fps @18mbps) I just recorded on my D5100. At lowest quality settings (424 30fps @4mbps) it says I can record 59minutes of video, so I assume the it doesn’t display hours because 1h 59m @4mbp is 3.5GB which is around the size of my ~26m video.
[Update 1st April]
Patch available from here: Nikon D5100 Video Beta Testers Wanted

I started looking at the J1/V1 firmware last weekend.
As compared to the DSLR firmware the XOR pattern is different, but using knowledge from the D5100 firmware, I made very quick progress getting past the first two XOR layers, the third was a little tricky.
Then yesterday, I got an email from Петр Кудинов that showed where in the D5100 firmware the XOR tables were stored. With this new insight (that they were stored verse calculated) I proceeded to search for what I had already found of the V1 XOR pattern in that firmware, and struck gold.
Here is the firmware based patterns used to decode the V1 and J1 firmware:

Of interest is that the file is packaged the same as the newer DSLR firmware files, but that the A firmware is the larger file, while the B firmware is tiny.
I have no plan to start work on a J1/V1 firmware hack presently, as the D5100 work is all occupying, but people are welcome to come over to the Nikon Hacker forums, and discuss this work if they would like to progress it, or help with the DSLR work.
[Update] The A firmware does not appear to be a Fujitsu FR CPU like the DSLR are.
Also there are references to “SANYO” and “SANYO Digital Camera” in A firmware, how very strange Nikon.
[Update: 25th March - Thanks to Петр for pointing out that I had a row missing from table three due to cut’n’paste errors]

When I was ten, Transformers where not that hard to transform.
Meet modern Bumblebee,
This transformer was crazy hard to transform, in the couple of days I was visting with the 4 year old owner, the head “popped off” multiple times, and I couldn’t get it back on without feeling I was going to break the toy. Lucky said child’s mother had the magic touch.
But transforming challenge aside, it was a pretty cool model/toy. Just not like the Starscream or Optimus Prime of my days gone by….
Wow, since doing the easy work of decrypting the newer Nikon firmware, I’ve felt an immense pressure to pull another rabbit from the hat, when in reality the last reversing engineering project I worked on took years (2-5), and thus I feeling real burnt out. a) due to trying to find the next “cool” insight, and 2) wanting to be part of the action, and keep up with others are finding. (the index scheme is an insiders joke)
To this end, I point would-be-helpers to nikonhacker.com, I’ve been contributing there, as best I can.
It’s very addictive having such large inflows of traffic to your site/blog, that I was reluctant to redirect it, but I have also felt since November a presure not to post stupid stuff like I used too, or am about to post, thus have been silent (besides the travel and working on things that are not up for chatter).
So there’s my Nikon update…. I have been having a good family holiday..
