Overclock Kindle Fire To 1.2Ghz With Custom Kernel

Kindle Fire 1.2GhzSince XDA-Developers forum member g1011999 released the sources while working on his ICS build for the Kindle Fire, developers picked up on those sources and are coming up with custom kernels, where these kernels are still a work in progress. That said, renowned Android developer DoomLoRD has also jumped into this development and released his version of a custom kernel for the Kindle Fire. The kernel is also OC’d allowing users to up the CPU’s clock to 1.2Ghz. More on the kernel and how you can get it up and running on your device after the break.

The kernel also overclocks the GPU to 384Mhz as well and employs an insecure ramdisk. Somewhere in between the kernel was breaking Wi-Fi and people were reporting drops. Hopefuly, that problem should be fixed with the latest release now. Also, this kernel is only meant for advanced users, because you never know where you might end up with a WIP custom kernel flashed on your device.

  1. you should really remove this. this is seriously early beta. doomlord hasn’t even recevied his device yet… he’s doing it all blind. this could cause a lot of bricks…
