DG4000 - a firmware investigation
scalargr:
hello to all,
I have for some time my F G 4102 without any upgrade (fw 00.01.03),and I want to upgrade it at 160 MHz .
My 1st attempts have been made with rory’s instructions Reply #67 on: November 16, 2013, 05:44:44 PM but It’s too complicated for me( I’m lacking knowledge of linux).
The 2nd was with bandgap instructions on Reply #104 on: November 20, 2013, 06:40:38 PM ... I made several attempts and combinations as described , but nothing valuable came out.
( something is wrong / I’m wrong???) ???
1) Go to http://www.compileonline.com/compile_c_online.php
2) Replace the code in the left box with the code below.
3) Put your command line arguments in the text box at the bottom (in the form <current model> <new model> <current serial>)
4) Press "Compile and Execute" in the top left
5) Press "Download Files" in the top right (assuming everything executed properly)
6) The result tar.gz file will have the proper license.CEN file contained within it.
I don’t want to use 200MHz
Anyway, Could someone post some detailed instructions step by step on that, or could someone make any upgrade for me?????
Thanks.
PS: I managed to h/k my msox2014a successfully .Thanks to the forum and the contributors ;)

Hi to all.
Can somebody tell me why it doesnt work on my serial (DG4B141xxxxxx) with FW 00.01.03 ???
Teneyes (thanks again for sending me the cen. files) helped me about that. I tried some different usb sticks, but It's hopeless. :palm:
I get ...<invalid license file> / <Excessive number of errors. Please restart>. |O |O |O

Guess I have to take the JTAG route.. Anyway, thanks for your work!! :-+

Since I purchased my DG4062 after this hack was discovered, mine has the updated bootloader. I was wondering if there's a way to fool it into thinking an older version of firmware is actually a newer version by modifying the version in the byte code. To do this we would need to accomplish two things:
* Find the address that the version number is stored at
* Figure out which CRC algorithm is used on the firmware upload file and update the CRC
Reverse engineering is not my strong suit but I'm going to dig into this, if anyone has some insight relevant to this please share!
