Thanks tv84 - that's great news!
At least there is no brick wall - small steps in the right direction and we will get there
Perhaps to help those with appropriate SSA3000x Plus hardware who are game enough to 'try' for themselves, we could post a failsafe recovery process from the 11 nandbackup images??
Easy enough to generate the backup images - but not sure if the recovery process is just plain simple restore the backup with a 'reverse' command script?
My worry is that if the device will be totally 'bricked' - so no access to file system (boot , let alone telnet not possible), then there is no option other than direct console access via PCB header.
Not so keen to 'break-into' new device just now if I brick it
Any 'passive' recovery method(s) would always be welcome - so more of us can 'have a go' at mastering the crossflash process

With soft pulling it in the direction of the front it came loose.
Successful upgrade
Also note.. some of the options vanished?
After restoration i just changed the version config file to the SVA code and ran the .7 ads file
Also here is the updated file to change the product id
its in /usr/bin/siglent/config

Congrats Elasia - especially your quick recovery from a 'bricked' device.
Looking at your SVA system Info page - I drool with envy and fully appreciate the taste of the sweet nectar of success you must be enjoying now

Thanks, yeah wasnt really bricked to the point of needing to hit them with jtag... it was my computer being a horses ass earlier and making all the serial port data garbage... switched to the tablet i use normally for reprogramming network switches... worked fine... pos comp lol
And yeah, tv knows what to do now to repack the firmware to convert it.. HOWEVER you need to buy the calibration kit, they do not come with SVA calibration data loaded, you must use the sva cali menu to do this yourself
I'll pick it up one of these days myself unless someone wanted to send me one ~
SDR-kits.net in UK has excellent SMA calibration kits up to 12GHz for about $65 US. Each set (male and female) is individually calibrated and comes with full calibration specifications that should be able to be entered manually into the SVA1032X

Those are good parts, but they are not properly characterised.
But probably good enough for the low freq range of the vnwa based on what I remember of their analysis. And so could be usable for the 1.5GHz SVA. However, the load resistance they provide cant be used for a custom cal kit, but the offsets can.
How to crossflash a SSA3000X Plus into a SVA1032X:
1. Telnet into the equipment
2. rename
/usr/bin/siglent/ecomb_p
to
/usr/bin/siglent/ecomb
3. in file /usr/bin/siglent/startup_app.sh change the line
/usr/bin/siglent/ecomb_p &
to
/usr/bin/siglent/ecomb &
4. in file /usr/bin/siglent/config/NSP_config_upgrade_info.xml change the line
<upgrade_static_id>11405</upgrade_static_id>
to
<upgrade_static_id>11403</upgrade_static_id>
5. Reboot
6. Now you can update your SSA with the Siglent's SVA stock FW.
(should work with SVA1032X_2.2.1.2.5 or SVA1032X_2.2.1.2.7, at least)
7. After having flashed your first SVA stock FW, the SSA has become a "true" SVA.
To lower the risk you can do an additional step which is to activate the telned daemon before the line reference in step 3.
(for example, place there: /sbin/telnetd -l /bin/sh -p 10101 & )
As always: do it at your own risk.

DTF could give you some ps delay measurements to add into Port extensions that might improve basic results without the need for Cal kits.
I have the Siglent 4.5 GHz SMA kit coming in a few weeks so hendorog and I will be running against several Cal kits he already has with Nano's, HP VNA and Signal Hound stuff he has.
Edit
Oh and how could I forget, also with a SVA1075X !

Teardown? ^^ pcb pics? ^^
oh thats a nice find noreply.. i'll have to get one of those
and yeah more than likely... you just need a similar kit to at least give it basic cal data

I guess we can always use the SSA part of the SVA to get some basic calibration of the VNA calibration kit's SMA connectors and associated cables
We can always normalize the basic 'test' setup and then 'plug-in' the various Kit elements - and get a decent calibration - so any discrepancies in the connectors can be factored into the final calibration of the VNA
This way we might as well use the US$1600 SSA we already have - to get some decent measurement and save some $$ rather than buy an expensive calibration kit
I bet after using SSA to calibrate the NanoVNA calibration kit's connectors - SVA VNA calibration will be close to the Siglent Kit's result
When you become familiar with SVA's UI you might find the setting to reset to the factory cal so to check any discrepancies between another Cal kit.
Start exploring into 0.01dB/div and you'll find differences alright.
