Hi everyone,
First of all, a huge thank you to this amazing community – this thread has been a goldmine for years and I learned a ton just by reading.
I just received a brand-new SSA3021X Plus and, as expected in late 2025, it came straight from the factory with the very latest firmware:
3.2.2.6.3R2 – build date 06.13.2025
I know this is probably the newest version Siglent has ever shipped, and I’m fully aware that each new release tends to close doors that were previously open.
I’m not expecting miracles, but I would be extremely grateful if anyone who has a unit with this exact (or very close) firmware could let me know:
- Is the classic telnet/DEBTTT trick still working on 3.2.2.6.3R2 ?
- If yes, is the old python keygen (the one based on the well-known 128-byte master key) still able to produce valid keys for SSA3032X / SVA1032X ?
- If not, has anyone found a new method or workaround for this firmware revision? (even partial unlock would already be great)
I’m perfectly fine downgrading if a safe older ADS file exists for the Plus series, but I saw that Siglent now signs the firmware packages and I don’t want to brick a brand-new unit on day one.
Any help, advice, or even a simple “sorry, this one is locked tight” would be immensely appreciated. I’m very happy to follow any instructions carefully and report back my results for the benefit of others.
Thank you in advance for your time and legendary patience with newbies like me!
