Siglent SPD3303X-E Hi-Resolution Output Unlock?
Jack24044:
An SPD3303X-E, 1.01.01.03.11R1, V6.2 cannot be loaded with 1.01.01.03.10 firmware.
Despite any claims as such.
The release notes state "This firmware version only supports V6.1 hardware version of SPD3303X/X-E".
BTW, the EasyPower patch above doesn't work: you will still get the message "This file does not match the device".
That's fine, as it could leave you with a bricked power supply otherwise. So don't do that.
While you can't convert this one to an SPD3303X yet, it could be fun once possible.
But for now I would suggest: buy the model you need, maybe spent a bit more on the SPD3303X model.
UPDATE: Holdon, below Terra came back "to the rescue" for me. (maybe)
He pointed out there were updated V6.2 models, so it must be possible somehow.
I don't know the issue yet, the procedure and modification of EasyPower described didn't prevent reporting "This file does not match the device".
TERRA Operative:
You can literally see the post above yours that someone did exactly what you claim cannot be done.
Did you follow the instructions properly?
Jack24044:
Hi TERRA, thanks for your instructions and thanks for coming back here.
I assumed only older hardware had been upgraded so far.
My unit reports: "SPD3303X-E, 1.01.01.03.11R1, V6.2".
Some post said it upgraded that, but I doubt it because EasyPower simply doesn't let you do it.
I followed your instructions to modify EasyPower, and verified the byte afterwards with HxD (I attached the screenshot).
Trying 1.01.01.03.10 firmware, EasyPower (V100R001B01D01P20) reports:
"This file does not match the device" and "Upgrade Fail! Please close the software and open it again".
So we likely have look for 1.01.01.03.11 firmware at

TERRA Operative:
Hmm, that different firmware may make a difference.
You maaaay have to wait for a "SPD3303X, 1.01.01.03.11R1" (non -E) firmware to be available, but user ttssyy was able to get it to work. Changing the bit in the update utility definitely prevents it from checking the '-E' or 'non -E' version before flashing, but maybe it doesn't have anything to do with the actual firmware version, so there may be something preventing you from downgrading from '...11R1' to '...10' version, maybe?...
I have attached the version of EasyPower that I used to my previous post with the unlock instructions, along with the modified exe, not sure if it will help, but maybe worth a try just in case a later version of the EasyPower software was modified to prevent this hack..

I could change 1.01.01.03.10 X FW to load on a X-E v6.2, BUT I think it's not advisable to do so, given Siglent's warning.
It's better to wait for .11 version or above.
Nonetheless, for those that want to insist, I think the patch being advertised is not complete. Another verification must be bypassed. I think one of the multiple ways to do that is to add this patch to the .exe (see pic): swap green bytes with red bytes.
