I have an Deciso DEC750 with I-225, originally it had FW version that wasn't listed, I managed to update FW to version 1.89 1mb variant, and I do have backup from original(s). One thing I wonder that backups from all 3 I-225 interfaces are 2mb even if the 1mb v1.89 firmware went in just perfectly initially.
Some background: Now the one visual issue is that interface led are just static green led and nothing else, it doesn't affect the apparent working of interface otherwise. But now the DEC750 reboots between 1-3 days, and I'm not even sure this FW mangling is the rootcause, but:
I can not downgrade / change firmware to any version, it always fails even when trying to push the original backup back... Here is some log of _a_ attempt:

So I suppose this is sort of "what could I try next?" -question :)
