I don't think you can use this kernel on such an old rom

    How to Install

    Instruction for flashing Tiamat Xoom Kernel And Boot Image Packs

    NOTE: These instruction assume you have flashed ClockworkMod Recovery and upgraded to Honeycomb 3.1!


    1. Proceed to the Boot Image Section and grab your favorite boot image. Not needed if you're happy with what you got.

    2. Proceed to the Download Center post and grab your kernel.


    1. Reboot into recovery.

    2. Go into "mounts and storage"

    3. Select "mount USB storage"

    4. Your SD Card will now be mounted on your computer. Drop the kernel (and boot image pack if applicable) onto SD Card.

    5. "Go Back" then go into "install zip from sdcard" then "choose zip from sdcard"

    6. If you are flashing a boot image pack, flash it first. Then flash the kernel zip. NOT FOR ANDROID 3.2

    7. Back out to main menu and reboot.

    Release notes for 2.0.0:
    Tiamat Kernel 2.0.0 Katana, is ONLY TO BE USED WITH 3.2. IT WILL NOT WORK WITH 3.1.
    Also, do not flash a boot.img as this will also break stuff at the moment on 3.2.

    Release Notes for 1.4.4: 1.7Ghz is likely as far as we can push the Tegra2 cores. We have stress tested the heck out of 1.7 and it is safe. However, safe does not mean stable. Personally, I can run 1.7 on Interactive governor all day and it's smooth as butter. Other folks get reboots. If you can not run at 1.7, try 1.6. Everybody who tested was able to run at 1.504 without any problems. Just because this release is clocked to 1.7, that does not mean you can not run at stock speeds. Simply do not overclock. The settings for 1Ghz are identical to stock settings. I HIGHLY RECOMMEND you leave your device on INTERACTIVE. You may use Performance solely for benchmarking purposes, but then PUT IT BACK.

    USB Tether: Plug OTG cable into Xoom. Plug phone with microUSB cable into OTG cable. On phone, enable USB Tether. On Xoom, run the following in terminal or script manager (Scripter, GScript, Tasker) of your choice.

    dhcpcd usb1
    setprop net.dns1

    The Xoom will not show any indication that there is a network connection. But pull up your browser and surf away. Like I said earlier, I tested this personally on the Evo with a Sense rom. It works perfect. However, there are countless devices out there. Your experience may vary.

    Tiamat Xoom Kernel Boot Images For Honeycomb 3.1 ONLY NOT FOR 3.2

    Be sure to flash your boot image first! Then flash your kernel. You can flash the boot image and kernel back-to-back in the same recovery session. Don't worry. If you mess up and flash just these boot images, your device will still boot.:rolleyes::rolleyes:

    About These Boot Images

    These modifications apply to all boot images

    • Enable MicroSD card in Android mounted at "sdcard/external".
    • Enable USB Host with and OTG cable mounted at "/usbOTG"
    • New! EXT4 file system mount mod for faster write speeds and killer Quadrant scores. Thanks TDR from AndroidCentral!

    Guys, I'm gonna be honest for a second here. I have made the instructions as simple as possible. They can be made no simpler. You are flashing a boot image because RAMDISK IS STILL BEING DEVELOPED! All you have to do is follow the instructions. I spend alot of time not only on development, but developing the simplest method of implementation possible. In a few days when I drop a new Mass Storage kernel, you will most likely have to flash ANOTHER BOOT IMAGE. You can blame GoogMotoCorp for not doing the MicroSD card right. Just follow the instructions guys. Ughhh :confused: :confused:
    Just want to point out that the link to the new kernel is NOT bigrushdog's kernel. Flash with good judgment. Also, I think it was bad manners posting that link here....should have started your own thread.

    Sent from my HTC HD2

    It's all good. No worries. Not like I did enough this week or anything lol. I am going to release Tiamat 1.4.2 today. Quite frankly, it's wicked. BTW, don't be fooled by ext4 filesys hacks to trick a high quadrant score. You guys remember my "hyperspeed" kernel? It was the same thing. I can get a 9000 quadrant score doing that. Put it has no real impact on device performance. Anyways, we got a killer kernel on the way.
