The BBC quotes an SSTL engineer as saying It was too early to say that the satellite was dead. He stressed that any spacecraft would be unstable immediately after launch, and that North Korea could be trying to rectify the problem.
"We take typically two or three days to get a satellite stable, and we know what we're doing - whereas this is the North Koreans' first try.
"It would be prudent to wait a little longer and monitor the tumble rate to see whether there's any attempt to stabilise it."

It seems the catalog number of the North Korean satellite is 39026 and the International Designator is 12072A, so according to https://www.space-track.org/perl/id_query.pl the latest TLE is KYS-3 1 39026U 12072A 12353.24685568 .00002596 00000-0 16246-3 0 333 2 39026 097.4049 041.9729 0060301 151.5616 208.8926 15.08756125 940
KYS is my ID for that flying box...
Catalog number and ID was found by a fellow ham radio operator HG5APZ.
