Hi I have an iPad Air LTE, and before 6 months ago it died. Before it died, the iPad didn’t charge and it stopped working in the middle on restore. (Error 14, 4014, 4013) Black screen, no backlight. Now I’m trying to fix it. I pulled up the battery and check it voltmeter. On the display is was 0.01v and sometimes 0.03v. My question is How I can make sure the problem here is with the battery? Maybe the logic board is dead too?
if the battery is reading less than 0.5V then the battery is 95% likely toast. That being said, i would try using a 5-10V power supply, and excite it. perhapse able to get it charging. but likely needs replacing. HOWEVER, there is a possibility of other failures as well.
