This is a simple tutorial on how to flash CM11 kitkat on a transformer prime. Like everyone else says no warranty.
The prime is almost identical to the TF300T. So we flash a TF300T version of CM11. The only side effects are that your device is recognized as a TF300T instead of a TF201.
First follow the guide on installing nvflash and making your device brickproof found here. https://www.androidroot.mobi/pages/g...ash-jellybean/
Remember to use the one for your device the TF201, I haven't tested using another devices bootloader on our device but it will probably brick your device so don't do it.
After you complete the guide above it is time to upgrade to the Hairybean bootloader. The thread is http://forum.xda-developers.com/show....php?t=2407248
You need the following file http://www.androidfilehost.com/?fid=23060877490002899
You will flash that via recovery
Once you are done with that get the TWRP recovery from http://www.androidfilehost.com/?fid=23329332407579270
the thread is http://forum.xda-developers.com/show....php?t=2691886
Flash that via recovery as well.
Now it is time to get CM11. You can get it directly from the cyanogenmod website. http://download.cyanogenmod.org/?device=tf300t
I downloaded 3-25-2014 but I would go with the newest build at the time of flashing. Again flash that via recovery. Also flash gapps, you can get it from here http://wiki.cyanogenmod.org/w/Gapps
Then just reboot. It may take a while for the first boot but everything is working. I have had trouble with GPS but I'm not sure if that is the rom or not.
Hope that this helps. Press thanks if it does.
