A couple of months ago I left my kindle connected to the USB of my PC and I forgot about it. The next day I grabbed the kindle and it was frozen, that is, I remain on a page of a book I was reading and there was never a way to defrost it.
Try all this:
-Press the button for more than 40 seconds to reset.
-Charge the battery until the light turns green and try the same and different steps of resetting youtube and the kindle page.
-I saw a video of how to disassemble a kindle, opened it inside and took out the battery and the connection of the flex and replaced them correctly.
-Everything remains the same, it is more 2 weeks ago the kindle has no battery and remains on the same page where I am frozen.
The only solution I can think of is to touch the motherboard of the kindle with a tin soldering iron, for that I think I need someone to help me. Someone should know how to do a reset of the kindle through the motherboard.
Is that or throwing away something that doesn't work for me more than a month ago. (I don't have money to buy another one)

Model motherboard "30-001931"
