Hi guys,

I would like to ask a question concerning the debricking of Kindle K3.
I've this model, but before 2 years, an incident with the display did force me to buy a new one. I ordered one through ebay, and installed it. It is showing only half of the screen with 50% displacement of the real image. (The full story is described here with screen shots: https://www.mobileread.com/forums/sho....php?p=2593925) Firstly I though that the video driver is incorrect. Now I am sure that this is the case, but one by one.

To make the long story short, I thought that the display that I bought is somehow defective, so I bought a new one recently, which in turns, not just give me the same result with the displacement, but also have a fuzzy lines like when a computer does have improper setup of the refresh rate. I did inspect the display it self, and it turned out that it has a i2c 64kbytes memory chip, where the firmware and all the parameters are kept.

I tried to update my K3 device, but with no success, because I've too many modifications of the firmware (so many that I've no idea anymore what I've changed, and even if I knew I wouldn't remove them). Anyway, I do not know what firmware version I am running because the version info is shown in the lower right corner, which is invisible for me, because of the misaligned display.

The only access I've is through an SSH terminal via WiFi.

My first question is how to review the K3 firmware version by using terminal?
And..
Is Kubrick able to update the kernel with the device drivers, not just the mmcblk partition? (especially when the firmware is not 3.4)

Thanks for your reply.
