Yes, I measured 10k between ground and battery terminal…

Its 0.509V & 0.507V - diode mode , And voltage is 3.4V

yes its glowing , Green while connecting ,,, then turning into orange

Feedback resisters were bad, Changed it, Couldnt find 1% tolerance one, Replaced with 5% resisters.However board is ON now,,,,,,, :)

Everything works fine with Charger,, But the battery not detecting...Where should I start looking ?

found something

Ok seems like there is no issue with AC2 , Is there anything else I can try ? Any hopes to get it back into life ?

App Store says that the AC2 available only from mac OS 14.00 and above

I’m using Mac OS Ventura for Apple Configurator, configurator was not available directly in App Store,Downloaded it from a third party website….Does it has anything to do with the restore failure?

L8100 diode mode- 0.266V

I have shorted the 3V3_S5 , now L7030 is measured 4.5V , Restoring is still failing with the same error The System cannot be restored on this device. Unexpected device state 'BootedOS' expected 'DU' (Probably caused by a transient USB layer issue causing missing or duplicate events)...

I have a top case of A1990 , can I use it with A1707 logic board? Or else at least the battery? Just waiting for the expert opinion on its difference

Am I allowed to connect 3V3_S5 to ground ? Just out of curiosity how is it going to help ?

At L030 I measure 10.4V during the restore process , is that normal? Or the board is just stuck and not happening anything?

How do I know real restoring is happening or not ? It’s stuck at this window from past few hours
