all PP_LDO lines missing
Hi,
I have an iPhone 6 board which seems to have all the PP_LDO lines missing (all of them). They are not shorted, as the resistance to ground reads in megaohms, but when the board is powered on (screen shows restore with iPhone) the lines are absent.
I want to ask if this is normal when the phone is in the DFU mode? More or less everything is disconnected from the logic board.
Unfortunately I do not have a known good board to check that.
Questa è una buona domanda?

most of these lines seem to lead to U_PMICRF so i would check around that area

This is the point. I want to distinguish between faulty baseband and faulty baseband PMIC. On the other hand it might be that these lines are software-activated and it is not that weird that these lines are missing.
