Hello,
I have a 2012 Kindle Fire 2nd generation (non-HD, build model KFOT), and the lower half of the touch screen stopped working. The image is fine, it just does not react to touch inouts.
Already reset it through ADB and cleaned touch contacts, so probably the digitizer is gone.
[[Item:Kindle Fire 7" (2nd Gen) Front Panel Assembly|On iFixit|new_window=true]] and other sites it is out-of-stock, does anyone know if someone still sells them/the part number for a deeper search?
