Have an older iPendant, A05B-2490-C371, that will not accept a firmware upgrade.
The current firmware is V6.20 and comes it comes up in the smaller legacy screen on 2 different R-J3iB V6.40P and an R-30iA V7.70P.
When trying to upgrade the firmware on any of these 3 controllers, it says it loads and installs but stays at the waiting for controller screen for hours.
Both the V6.40P and the V7.70P software being used for the update attempt are very recent and new reburns from Fanuc.
Is there something I'm missing? Another iPendant with firmware V6.23 updated just fine on the R-J3iB.
