Sorry for late answer - manual search/adding did not help, but I found answer in this forum:
Off-7 secs on-3 secs off-7-3-7-3-7-3-on had to be done 6 times (not 4) and leave unit for 2 hours.
When I returned after that it had downloaded firmware 2.13.10 and is now accessible. Thank you !
EDIT: and I was able to repeat the process - as firmware was now 2.13.10, it still wanted to update (to 2.14.x) and failed again. Same cure and 2.13.10 is back again. It look old Dialog has issue to upate to 2.14 series.
