A firmware update to make existing hardware have a longer lifespan and help Ericsson to retain their clients was likely the only out here. If Ericsson had the new chips they were planning on, this firmware update would be much more expensive and less probable to actually see carriers taking them up on it.
That is actually Nokia. Not Ericsson
You take SemiAccruate as reliable sources, and even if the rumour were right. Ericsson was / is never disclosed as an Intel Custom Foundry Partner.
The only self disclosed Telcom Equipment manufacturer using Intel 10nm is Nokia, and BTW where is the NOKIA bankrupt and "no way out"
Seriously, this is HN, not Reddit.
FYI, Ericsson admitted to this silicon problem negatively impacting them recently: https://semiaccurate.com/2018/08/30/update-to-intel-custom-f...
