Anyone have 8.1.0.2 and/or any of the flavors between 8.0.1.2 and 8.8.0.5 in 64bit? Pm me!

8.1.0.1.

much obliged sir!

[figgie]

already tried... all 64 bit software is showing the latest MAUI 10.X

Interesting, they have removed them since I looked last year. Possibly to prevent unlocking licenses by downgrading?

Have you tried if upgrading to versions 10.X works? For the older 32-bit scopes installing an older version officially supporting that scope first (for the drivers) and then upgrading to a later 32-bit function worked as far as I know.

I tried going to MAUI 10.6.x.. that version sees the 16 character keys but does not apply them.

ok minor update...

8.1.0.1 - shows ONLY the 16 character options and the options work. Unfortunately, it does not show the 26 character options (either normally or in the svc menu). I am thinking from the documentation. 8.1.2.0 was a major release...

8.7.0.5 - shows both 16 character (legacy key) and 26 character. 16 character legacy keys though showing are not being applied unlike 8.1.0.1 (highest version tested at this point) with operational options on W7.

Hi,

i have a HDO6000-MS with an X-STREAM 7 firmware running. I like to "recover" some options.
Can someone explain me, how I recover the SW options.

So what files i need zu extract and so. Thx

Differences between MAUI v10.8.0.0 and v10.8.0.5, for those interested.

Hey All,

I have a Wavesurfer 424 and did an upgrade to an SSD (Transcend TS32GPSD330) and had 2GB of RAM laying around that I put in as well. Boots up fast but for some reason, it displays the "factory calibration data has been moved" and none of the settings seem to have been saved.

It appears that if I do make some adjustments, shut down the scope then start it up again, the settings are saved. All of the cal data is there on the D: drive so I think it's just because of the drive change.
 
It seems the registry key HKEY_CURRENT_USER\Software\LeCroy\Maui\ShowCalibrationDataError should be deleted and everything will be back to "normal". Can someone confirm this?

Edit: Found the solution to the serial decode menu not showing as @RedCali had the same issue: https://www.eevblog.com/forum/testgear/lecroy-options-recovery/msg3352494/#msg3352494

And one more thing - I can't seem to get the serial decode option to show up. I have the following options set:

• Hardware Options: ATP
• Software options: DECODE_MEASURE DFP2 EMC ET I2C JTA2 MSURF PMA2 XDEV XMAP XMATH

What am I missing here?

Thanks!

After many hours I found where licences in Waverunner HRO 6Zi are stored. I have 2 types of these 12bit scopes - newer version of CPU board with some extension card and running with SSD (type WRHRO 66 Zi) and Win 10 and older version with win W7 (type WRHRO 64 Zi).
After change all parts between scopes I found licences are stored somewhere on CPU board - not depends on HDD or sampler board etc.

It is on Dallas chip - 1wire eeprom  28EC20. And there (although I hoped) are not only some switches if use or not the option - like in most of units, but there are stored a crypted keys . For communicating with this is used SM bus driver (see HW settings in Windows).

Structure of data are:
- first block has ASCII licence codes for legacy keys.
- second block has ASCII licence codes for legacy keys with temporary activation (demo codes)
- 3rd -  next block has new licence keys, but stored in 16bytes (not in 26bytes)


each block has info how many keys are in the block stored and if this is enabled (0x01) or disabled (0x00) key.

In the last bytes of memory is saved unique ID called "unspecified value" (see its datasheet). This ID is the same ID in the scope - called Scope ID. This value is in ROM section - not rewritable and by this are calculated licence keys.

Using this I was able to bring the licences from one unit to another and is possible to clone licences. Not possible direct copy of Dallas chip (has unique ID), not possible to use bigger memory chip (this Dallas is 20kbit and larger is not available , but is possible to use emulator with some micro. Maybe should be easier when some chip with deeper memory will be produced or with the china "fake" with editable ROM section.

Interesting is that the keys are converted back to 16bytes format. I made a test: program new 16bytes key with programmer into Dallas - this key on the scope is visible as 26bytes key (is recalculated by SW).


Of coarse, the easiest way is to generate the licence code directly and use them , but I have not find this keygen yet, so for me is now better to build Dallas emulator and use a known combination of ID and keys.

Conversion unit 64Zi to 66Zi is done after unnamed option key.

I will add the dump of chips.

I found some diagnostic list glued under PC board, there are visible all voltages - useful for scope repair. It is on photo.
Next interesting is handy cut for USB-B connector on new scope. So Lecroy produces handy made scopes and improvizes in few pcs, this is crazy work..

Be careful.

I spoke to Lecroy at length and they informed me that the HRO models (12 bits) of the Waverunner had a massive bug with Windows 10 and they did not support it (and i was talking as a paid purchase). The Non-HRO models of the Waverunner can in fact be upgraded to Windows 10 without issues.

More than likely that is the difference in motherboard layouts you are seeing.

1 is a HRO model (12 bits) and the other is just a normal Waverunner (8 bits).

I will add the dump of chips.

Please do.
