Re: a1398 boot loopt

So to clarify: You replaced the damaged battery, and now have boot loop?

It's important to note: On the 2015 A1398 models, a board/unit will boot-loop (sometimes) if you install a new battery and it has a very low charge. Let the new battery charge up (unit off) to ~30% or so, then test it again. If it's still boot-looping, then the issue is something different. But we've seen a TON of 2015 units that 'boot-loop' and power-cycle due to a low-charge battery that was just installed.
