Introdução
Ir para o passo 1 ↓My Kindle 4 had a motherboard issue and did not start even after I changed the battery. Fortunately, I found a second Kindle 4 with screen damage to salvage a working motherboard and change it.
Although removing a damaged screen from a Kindle 4 is pretty difficult, changing the motherboard proves much easier. Every single part of the device is glued, but the glue is sensitive to heat and will not be such a bother.

Amazon apparently discontinued service for this model: the service will expect double authentication, which apparently is not implemented in the Kindle firmware.
However, you can still use your Kindle 4 with USB : it is recognized as mass storage, and you can load ebooks in PDF or MOBI format in memory.
