[RELEASE] LogicMachine firmware 2025.12

[CristianAgata]

Hi.
I have an LM5p2-PMC. The device label shows:
LM5p2-PMC
LM5M3V30B24090197

In the upgrade window the device reports:
HW: LM5 Lite + Ext (i.MX6)
SW: 20240426

I am trying to upgrade to firmware 2025.12 using the row:
LM5 Lite + Ext (4 or 6 DIN units)

Files used:
lm5m3ex-20251204.img
lm5m3ex-20251204.sig

I have downloaded both files several times and rebooted before trying the upgrade, but I still get:

“Signature verification failed”
Can you confirm whether the 2025.12 signature file for LM5 Lite + Ext / LM5p2-PMC is correct, or if this device requires another upgrade path?

Hi,
Devices are new, just unboxed? If yes before upgrade set the correct time of the LM. I had the same problem on LM5Lp2 and I fixed in this way.
