I see.

In this case, please save KB545B.BIN from this archive to a preferably empty SD-card using an SD-reader (saving it using the camera's USB-connection was not tested).
Insert the card into your camera, right after insertion the camera will check the firmware for correctness, and if everything is Ok it will ask you to remove the card, and then install the firmware.
Please let me know if this helps.

It works! Many thanks ABel!

Just double checking - there is not a way to upgrade to K-50 firmware supporting PLM for the K-500 - correct? The attempts to date have resulted in locked up cameras that were recovered using the methods listed in the last few posts but not working PLM if I understand things correctly.

I surely can make that firmware.

The problem is K-01 firmware is 0x40000 bytes less than for K-30. And existing K-01 cameras simply don't know and don't expect there's something more to flash into their memory. Which means the K-30/50 firmware will most likely be installed incompletely.
)
I wonder if there's junk data in the k-50 files that can be removed. Bunch of zeros for example.

That's right.
And you've answered to wallyu's question quite correctly.

There are several seemingly empty blocks - some of them are filled with zeros, others with 0xFF.
But "squeezing" the firmware is as complex as its complete re-writing.

Any... tiny... chance for a K50 firmware modified for the K500 ?

I'd say the chances are close to zero.

The hardware difference between K-50 and K-500 is most likely very small.
But even that slight difference was enough to brick those two K-500 when K-50 firmware was installed in them.
And it's completely unknown which part of the firmware caused the camera hang.

The firmware 1.02 for K-500 was released at the same time with the version 1.02 for K-50, and it should be possible to figure out the differences in the firmware logic.
After these differences are identified, the same places of code should be located in version 1.10, and changed accordingly.
Who wants to try?

I' afraid my brother's K500 was sold 2 days ago, he is now a proud owner of a K30 with white solenoid and 1.10 firmware!

I'm curious for what purpose someone would "hack" a Pentax camera's firmware? What would it improve?

One useful feature would be a permanent debug mode or at least enable the AF Test without using PK Tether.
Another feature that might be possible a lower base ISO and perhaps eliminate the 25 minute limit for video

That would depend upon the amount of time available and the individual abilities of the programmer doing the reprogramming. It could range from simple improvements to autofocus calibration access, removing time limits on video recording (already mentioned), documenting tethering access for programmers so they could write open source drivers for tethering software, to improvements in the camera's menu system. Features like focus peaking could be added to cameras that don't have it, or improved in cameras that do. One simple example of an improvement I have seen in focus peaking (I think in the Canon hacking community) was to give the user a choice of the colour used to highlight in-focus areas. Another simple improvement to make is to redesign icons and symbols used to make them easier to read — camera manufacturers don't always do a great job of this kind of design and if a hacker has access to a good graphic designer this isn't hard work, just time consuming. A seriously skilled programmer with specialist equipment could even speed up or otherwise improve autofocus performance, though I wouldn't expect that to happen in the real world. I think in the Nikon hacking community a programmer improved the battery life of one particular model.

The sky is the limit really, though modest but useful results are more common than dramatic improvements.

is there a way to modify K3II firmware, I would like to enable dialing the astrotracer magnetic declination compensation manually, should be quite simple.
My main programming knowledge is by far java, however i could catch up with c, and c++ ( havenīt used them in 10 years ).
So first i would need to decompile the K3II firmware, which i don't know which tool to use.
Then editing, if possible and then compiling it again.
In my mind it doesn't seem to be complicated, for sure the camera is maintaining some kind of magnetic declination compensation internally so the new functionallity would just need to allow me to change that value, that's it.
An alternative would be to make the camera to read that value from the sd file.
Ideas?

ps: I have downloaded https://github.com/i-am-shodan/PentaxFirmwareTool
I compiled it and tried it to decrypt the K3II firmware that is in the zip provided by pentax, however the process fails as the XOR.key provided in PentaxFirmwareTool does not match firmware size.
I wonder were did they got that xor.key and how could i get the one for k3II. If the non encrypted version is available then calculating the xor file would be easy, providing they are still using same xor approach.
pps: well after reading a bit, it seems efforts on hacking pentax firmware has been abandoned, and if it is pure assembly i guess i would be dead.
