@Shodan: Can you edit the first post and insert links to:

• Pentax Hacker Development Kit Wiki
• https://github.com/i-am-shodan/PentaxFirmwareTool
• https://github.com/i-am-shodan/PHDK

and maybe to your PDF: https://www.dropbox.com/s/ogez7sb4b0cw92g/hacking_pentax_k30.pdf ?

One question: Does anybody compare the K-30 with K-50 (and/or K-500)... Are the hardware 100% the same?!?

Last picture looks correct begining of firmware file. I can't say exactly, because I work on another model (K-5).

[uttam.hathi]

This output is correct. Do not know what do you expect.

[uttam.hathi]

its FF FF across

[bootcoder]

its FF FF across

FF in unused areas of flash is normal. But the header with A5 5A and 00s is correct. Just scroll further.

can anyone run pfwtoolwith K-30 and K-50 firmware and make a diff?

scrolled across but could not put the snapshot
Hex FF to decimal explained: The value of HEX FF in decimal is 255. The value of HEX FF in binary is 11111111. F, 15 X 160 = 15. F, 15 X 161 = 240. HEX FF = ...

Just search for some string like "DEBUG MODE" and you'll find it (with many other interesting strings around) if properly decrypted

[uttam.hathi]

it has garbled in the XoR process thus no effective strings
anyway debug mode i know, namely
K7: MODSET.474
K20D: MODSET.442
K200D: MODSET.445
Km : MODSET.464
Kx: MODSET.492



[OPEN_DEBUG_MENU]

K10D with firmware v1.10: MODSET.421

K10D with firmware v1.20 -v1.30: MODSET.TXT

GX10 with firmware v1.10: MODSET.429

GX10 with firmware v1.20-v1.30:MODSET.TXT

GX20 v1.01, v1.03:MODSET.454

K20D v1.03:MODSET.442

K200D v1.00.00.03 :MODSET.445

K7 v1.01: MODSET.474

Km v1.10: MODSET.464 press "Delete" during turn-on

K2000 v1.10: MODSET.482 press "Delete" during turn-on

Dumping

Now you can dump any firmware from most PENTAX DSLR models.
How to do it?
Make two MODSET.xxx files

First MODSET.xxx file
[CPU_ROM_STORE]

Second MODSET.xxx file
[DSP_ROM_STORE]

Copy first file to root of your flash card.
Turn on your camera. Wait before dumping is completed. Turn camera off.
Copy second file to root of your flash card.
Turn on your camera. Wait before dumping is completed.

You'll have two files on flash card now.
__________________________
Create two files on the root of your SD card:

00077650.524
DEVELOP.MOD


Open the 00077650.524 in notepad and add the line:
[OPEN_DEBUG_MENU]

Put SD card in Camera but leave the door open.
Turn on.

First strings come in K-5 firm at offset 0x3000 (that is a part of update code).
