You may be aware that verygreen is working on CM10 development for the 8.9" Kindle Fire HD. I am also working on getting this working on the Kindle Fire HD 7".
-Almost nothing so far. I can get past the bootloader and CWM will run (Thanks, verygreen!), but the CM10 ROM still needs to be developed further. I can flash it, and it appears to complete, but nothing comes up on the screen.
Trust me, this will be a slow process, but it IS BEING WORKED ON!
I will post any progress that I make.
[12/4] I now have screen working.
[12/5] Boots fully, but no touchscreen and the resolution appears to be wrong. (see image below.)
[12/7] Touchscreen now works, but is off by 90 degrees.
[12/8] Basic functionality appears to be working now.
Wifi works, and screen and softkeys are all working now too.
Check out the video:
[12/10] 210 seems to be the magic DPI number for this device. Thanks to all of you who suggested that.
