I can not see the im28.cnf being an issue as that is processor specific where as the ICEBear itself is not.
I did see in the icebear.cfg file that they warn it is not tested on actual hardware.

[b]echo "WARNING!"

I found this and maybe you want to give this config a try

Create your own icebear.cfg file with these contents and use it instead of the supplied one.

I hope it works for you

Hi Guys,

I don't want to disturb, but I have bought me my first oscilloscope - a Rigol MSO1074Z. Yesterday I discovered that the ability of decoding RS232 information is only trial. But the advertisement said, that this is a feature. So I tried to generate a key with the software from "http://gotroot.ca/rigol/". But no success yet. When I now enter a key it displays a message that installation is blocked for 12 hours (also mentioned on page ~ 126 of this thread). So I interpret this as a "NO" and retry in 12 hours. The numbers are:

Model: MSO1074Z
Serial: DS1ZC1xxxxxxxx
Firmware: 00.04.01.SP2
Board: 2.1.1

I've tried the private key 0x6f1106... for DS1000Z series with options DSFR and CSAR without success. I need to retest the private key 0x99fc5... MSO1000Z series for CSAR but I don't think that this will work (because I have possibly tested this).

So could you provide me some help. Do I have the right private key and/or "feature" codes (DSFR, CSAR, ...)? Isn't there a reset possibility to bypass the 12 hour waiting time?

Greetings from Germany,

Thank You , Sandra.

I have no time right now to again disassemble the scope, I will test it within several weeks.
I compiled the openocd 0.8.0 with new ftdi library, so old interface ft2232 i think not work anymore. However i will try.

I think that slow down the interface can be the solution.

Mythbu, you must get a JTAG adapter, install openocd, dissasemble the scope and follow the Sandra's Tutorial back in 252 page of thread. Good Luck!  :-//

Happy new year!!

Look starting at the message from 0ff
msg565557 and from that message forward several of us discussed and detailed how to do it.

Basically you have to open your scope up and use a JTAG programmer to dump memory then use rigup to get the private key then use rigup again to generate the keys.  riglol does not work for the MSO1000Z series.
I posted here where I did this for reference. msg569236

So has anyone tried this yet?  I am on 01.09, bootloader 01.03.  I am afraid to try it until I know it will not 'un-hack' the box...
