first post here on the eevblog. First off, really great work guys (and gal), and nice video Stevey. Took a while to read all 258 pages of this thread, but I've still got a few questions:
I've been asked to "liberate" the features on an MSO1074z-s for someone. It seems that the hack for this is still a "work in progress". I don't fancy trying to remove the waranty seal from this guys scope. Is it just a matter of time before the Key has been found so that this scope can be hacked with Riglol like the other scopes, or is there some factor that means it will always require a RAM dump to get the license info?
If it will always require a RAM dump: I don't have an Olimex, but I do have a Chinese clone Xilinx USB Blaster USB-JTAG. This one I think: http://www.ebay.de/itm/171008779562 . Does anyone know if this will work with Openocd / imx28 ? Or will I have to buy an Olimex for this?
Thanks
McBryce.

Hi,
Essentially the JTAG interface has to be compatible with the ARM processor and with openocd.
This should work, although you'd have to wait for shipping http://www.ebay.de/itm/JLINK-J-LINK-V8-Emulator-ARM-4-74B-MDK5-0-PRTR5V0U4D-JTAG-Interface-Auto-Update-/271596747000

USB Blaster should work.
To unlock the 1054Z can I use the website with the keygen, can't I? It is possible to reverse the process if for some reason I need to send it to warranty?

I believe you can uninstall all the options by issuing the SCPI command :SYSTem:OPTion:UNINSTall over LXI or USBTMC.

I thought the DS1000Z did not need to dump memory. Only the MSO1000Z's needed that.
I would try using the site or rigup first before doing a dump. no sense in opening it up if you do not have to

Correct, the 1054Z does not need to be opened up. Just use the website or download the executable and run it on your system.
I have heard you should run it several times if using the website as it sometimes has problems giving a correct key. Run it until you get the same key several times.
