DG4000 - a firmware investigation
PA0PBZ:
Perfect! I was just too late buying the DG4062 and got 1.09 with it, so the license file trick didn't work. I studied cybernet's work but this processor just gives me headaches :-//
Anyway, liberated after all :-+ So can we now safely update to 1.13/1.14?

Yes, after correcting what needs to be corrected you can go directly to v1.14

tv84, 1 000 000 THANK YOU!!!
My DG4102 has had from factory a FW version bigger than 1.08, so until today it could never use 'license.CEN' files generate by 'cengen' tool. The message was Unknown format file.
Now, using your modified firmware to downgrade to FW1.08, then generate a license file to turn DG4102 into DG4202 using your cengen.exe, then upgrade to the latest FW1.14.01 from Rigol, it worked! :-+
Former DG4102 (max. 100MHz) is now upgraded to a DG4202 (max. 200MHz)! :scared:
--- Code: ---Reminder of the main steps to do the upgrade
==================================
1. Upgrade normally to latest FW1.14.01 from Rigol
2. Downgrade to modified by TV84 FW1.08
3. Use cengen.exe in Windows to generate a license file for DG4202
4. Read the CEN file with DG4102 FW1.08 modified
5. Upgrade to latest unmodified FW1.14.01 from Rigol
DG 4102 should now be seen as DG4202 and the max allowed sinus frequency should be 200MHz.
-------------------------
-The USB drive should be formatted FAT32
-DG4000Update.GEL should be copied alone on the clean formatted USB drive
-To update FW
- insert USB with desired GEL file
- power down the DG4102
- keep the 'Help' button pressed while pressing the 'Power ON' button
- release the 'Help' button when 'Utility' button starts to flash
- from there, leave the unit running, the buttons will start to blink one by one, starting with 'Ramp'
- after about 10 minutes, the DG4000 will restart itself, firmware update is now done
-To see FW version press 'Utility' -> 'System' -> 'System Info'
-To see detailed version press 'Utility' -> 'System' -> 'System Info' -> 'G1' ->'G3' -> 'G5'
where G1...G5 are the grey buttons on the right of the screen

I bought a DG4062 base model as a Black Friday deal from their clearance/demo section.
It came with v1.12 if I recall.
So tv84's hacked firmware would allow me to reverse flash to a earlier version ... hack the firmware, and then upgrade back to v1.14?
Is there something I can do now to back up my machine before the flashing without opening the machine? There is still a 90day warranty on this clearance unit (I think).

Without opening it, no.
