Custom Firmware on Lenovo P70A
I have been using my Lenovo P70A for almost one year until now, but recently I get more and more feedback from my partners, that they do not hear what I am saying, when we are talking over the phone. This is some kind of audio problem of the phone, so I thought that this can be fixed by upgrading the firmware of the phone, so I started to experiment with custom firmware. In this blog I explain all the details of upgrading firmware, making backup of your actual firmware and data, and about the tools related to the firmware upgrading.
