    Default [HOW-TO] Overclock Nook to 1100MHz (stock + nookie)

    The Nook's processor can be stably overclocked to 1.1GHz!!!

    Credit to dalingrin, whose xda thread can be found here:

    Here's how:

    INSTALLATION ON STOCK (BARNES & NOBLE) ROM:



    Place it in the root directory of your SD Card (sdcard/).

    Reboot into ClockworkMod Recovery (if you don't have this yet, get ROM Manager from the Market and choose Flash ClockworkMod Recovery option)

    In Clockwork, choose Install Zip from SD Card

    Choose the file

    Reboot, and you can now use SetCPU to monitor and tweak the overclocking


    INSTALLATION ON NOOKIE FROYO (RUNNING FROM SD CARD):

    Download to a computer.

    Connect your NC (booted into Nookie from SD card) to your computer

    Select the option to mount Nook for USB storage

    Open the drive for the Nook's SD card on your computer

    Drag and drop the uImage file onto that drive (it will replace the old uImage, which it'd be wise to back up before doing)

    Reboot your Nook and enjoy the Nookie overclock!


    INSTALLATION ON NOOKIE FROYO (RUNNING FROM INTERNAL MEMORY):

    Download to a computer.

    Place it in your SDK tools directory on your computer (make sure it's called uImage)

    Open a command prompt from that same directory, and enter the following:

    adb shell

    mount -o remount,rw /dev/block/mmcblk1 /

    mkdir boottmp

    mount /dev/block/mmcblk0p1 boottmp

    exit

    adb pull boottmp/uImage uImagebak

    adb push uImage boottmp/uImage

    adb shell umount boottmp

    adb reboot

    If, after installing, you want to restore the stock kernel (on nookie in internal memory), enter the following from tools directory:

    adb shell

    mount -o remount,rw /dev/block/mmcblk1 /

    mkdir boottmp

    mount /dev/block/mmcblk0p1 boottmp

    exit

    adb push uImagebak boottmp/uImage

    adb shell umount boottmp

    adb reboot

    That should take you back to the stock kernel.

    Enjoy!

    I'm not using the overclock kernel, but there are general recommended setcpu settings in the work-arounds for stock nook color ROM stickied thread. On the stock ROM, you'll probably want 600 min to avoid lag.

    so by doing this overclock, you think it will have any heating issues? or cutting down on the life of the nook from running it so hard?

    There is a little heating on the upper left side but it's not too bad. As with any overclocking there will be a degradation in lifespan but it could be that instead of lasting 8 years it only lasts 4. By then you'll want to pick up something new anyway. Use setcpu to adjust the max/min settings and you should be cool.

    Maybe try a reboot? I had that happen once, seemed to be a fluke.

    For Setcpu, I have min/max 300/1100, with a 300/600 screen off profile. All using ondemand governor. I haven't noticed any alarming heating going on.

    Forgot to mention I'm on nookie. 300 min when I was on stock (before overclocking kernels) was too slow for me.

    Did you do the screen off/on thing? Just put your device to sleep for a sec every time after you reboot.

    Avoid the update, unless you want to lose all your post-rooting setup (possibly including the kernel -I'm not sure if it affects boot or not). See the thread on tips for disabling the OTA (hopefully).

    They were pretty quick with the last update, but your guess is as good as mine.

    I've ran into a problem. I overclocked it, selected "clear cache & data" after selecting the file through ROM manager. I've lost everything. My screen is the initial screen when rooting NC and my screen doesn't recognize my touch. I need help. Can I get back to where I was?

    Update: It's wiped everything clean...under Settings I'm not registered as the owner now.

    After selecting " Install from SD Card" there are 2 options. backup or wipe clean (i think), which one is the correct one to select?

    Yeah, you wiped your data. I think you clicked on the wrong menu. Install from SD should only let you choose a zip - not wipe your data or backup.

    If everything works fine, you may not need to restore to stock in order to continue re-downloading all your apps, but if you get any errors, that will be what to do (see stickied restore to stock thread).

    At this point, the only way to get your data back (aside from manually re-installing everything you had) is if you backed up via Clockwork or something like Titanium Backup.

    I can't even get to any applications...it's taking me first to the stock Nook Color screen>two options: Quickstart or Setup Wizard> setup wizard doesn't allow me to interact with the screen when pressing the android icon robot.

    not sure how to solve this. I think I hadn't backed up my data with Titanium yet (lesson to all!) but at this point, how can I get back to normal to re-root?

    UPDATE: I'm at the CLockworkMod Recovery system screen from booting it up. Gives options like-reboot system, factory reset, wipe cache partition, etc. suggestions on not losing it all from here?

    Check out the stickied restore to stock thread. That'll give you everything you need.

    In response to your update, no, you've already lost it all because you wiped your data partition. But if you have clockwork going, you can have an easier process restoring to stock. Everything you need is in that thread.

    I've never heard of that. If you're sure you followed everything to a T, then maybe hold off on the kernel. Could be worth another try though, as that isn't usual.
