This firmware version is stable since the last two days on a SLZB-07MG24. Let's see if it will be as stable as 2025.12.2-pre2.

For the records, I had to do an APP clear on the dongle as the first iteration of this 2025.12.3-pre1 release has a small issue which locked my coordinator. So, I started completely clean...

By the way, thanks at Nerivec for all the great tools provided and how fast you were to correct the minor bug👍

Hi @Nerivec,
Did I miss something?

I just flashed your version over SMLIGHT dev 20260416.
After rebooting Z2M, everything works perfectly. It shows version 9.0.2.

The only minor UX "issue" is that it shows "unknown" and "-1" 🫣

Thx dude 👍

[Nerivec]

You shouldn't have to. That was mostly an smlight mg24/26 issue, but last couple versions should cross-flash better even for these.
In any case, you can always do it again if you encounter troubles. Might as well avoid the shuffling of a network restore unless necessary.

[Asmir1975]

Should I continue with the "Clear NVM memory"?

Just flash over it like I did. Worked for me 👍

FYI: @Nerivec
SMLight took down the dev firmware 20260416 today.
Revision 20250220 (8.0.2) seems to be the last available for now.

Hello,
Thanks for your answers.
I'll flash without erasing nvr memory , like I always did in the past because the option wasn't present.

@Asmir1975 Seems they changed some stuff regarding update channels (stable vs dev); might be that?

I haven't received any issue for 9.0.x so far.

Probably.

Not really. But v2025.12.3-pre1 has been rock solid for a few days now. 🚀

@Nerivec Is there a reason for SL_ZIGBEE_KEY_TABLE_SIZE being smaller than the default 6 entries? 🤔
