Hello,
one of my dna 250/166/167 2-Cell doesn't work as soon as I install any firmware higher than sp5 (sp5.1, sp6).
As soon as the newer firmware is applied I get "check atomizer" when firing and the atomizer analyzer shows question marks for the ohm values.
When I rollback to SP5 everything works fine again.
Any ideas what the issue could be?
The chip i have no issues with has the following production history: Saturday, May 6, 2017, 12:41 PM
