apple dead loop

My Problem

I've got the dead loop at the start because my battery went so low that can't be charged.

My Fix

I've tried all the soft tips given on the internet and nothing worked for me.

Changed the battery and still the same.

Changed the charging port and still the same loop.

I've changed those components because my ipad was having problems to charge and being identified be itunes before the loop. So I suspected something wrong with those components.

I didn't have any trouble with the mounting/unmounting. The guide was clear. The speaker cable is troublesome to be removed and very weak so extra care is needed here but nothing special.

My Advice

The loop was still there, so I did something new. I took off all ipad power consuming components but the motherboard and blind charged the ipad for and hour. After that I connected the ipad unmounted to itunes and it worked! I let it have a full charge and after getting it together again it works perfectly.

Thank you all for providing the tools, tips and guides.
