apologies for double-posting, but this is my last hope, so wanted to make sure it's not burried and overlooked.
Posted this in a rather old thread the other day because there member "shaotangyu" in post 96 had the same very rare error message
"Boot error ocuured!. Error Code: 3039"
Note the typo in "ocuured" which is absolutely unique - g**gle finds 5 hits in total if forced to search for the exact match of "Boot error ocuured!." instead of the correction it suggests. Unfortunately shaotangyu didn't find a fix he replied.
The 2nd g**gle hit leads to a 2nd thread on here (with a different 4-digit error code) - but what the guys discuss there is beyond my options (I think - got only half of what they do).
Been using openWRT on my good old Linksys for ages (man, getting old!)
Now I have fried my FritzBox 4040 using the "recovery" tool provided by AVM. Seemed to update well, reported success, then lights went dark on the box, end of story.
Been through a lot before I came here now. Unit still creates various LED signals when LAN cables get connected to the individual ports. But there's no way to detect it any longer in the early boot phase.
I've then connected its TTL connector to the one of my CubieTruck and managed to get some (though apparently not all) boot console output - but that ends in above error message.
Fingers crossed, any and all hints greatly appreciated!
Here's what I get on the TTL:

And that's the final line.
***: see shaotangyu's post linked above, at the end of his code snippet: he's got around 15 or so more lines at the start of that "final section" he recorded - can try by other means to get those lines from my box if it would help?
