    Depends on the kernel. You can flash a kernel using ADB. Some kernels are available as a TGZ file which can be installed with SPRecovery, and some are available in update.zip format.

    They allow you to overclock to higher speeds

    The Kernel is one of the most basic parts of the operating system. Essentially, it lets the hardware and the software communicate. Many things have been added to kernels, such as support for WiFi tethering, the responsiveness fix for the touch screen keyboard, and overclocking capability.

    With adb, reboot into recovery and then

    flash_image /sdcard/kernel.img

    With nandroid or .tgz I imagine you already know.

    Here's my question..

    Is there a kernel that allows OC to 1200 MHz, has the touchscreen/keyboard fixes AND allows Tempmonitor to see the actual CPU temp? :eek:

    Hmm... can you issue those same commands through Terminal Emulator as su? Doing it all straight from the device is a lot more convenient, in my opinion.

    Could someone fill me in on these touchscreen/keyboard fixes? I have never heard of these. What are they? Watch, I'm probably using a kernel with them included and don't know it. :rolleyes:

    @ dfine - Because some roms bake in the OC kernels. Pete recently decided with 2.1 roms (not sure on the 2.01 roms) that he will let the user decide. I think he only includes the 600 Mhz one. Then he links to several different kernels so the user can decide which is most stable for their particular phone (and what the max overclock is of each kernel)....

    Someone please correct me if I'm wrong :)

    Unfortunately, not yet... I'm jumping on the kernel development train, so I'm hoping to have exactly that in the very near future. :D:D

    Edit: I take it back - the SholesMod 2.0.5 kernel has exactly what you asked for! I just loaded it from a previous nandroid and it has the touchscreen/keyboard fixes and allows for CPU temp using TempMonitor.

    not all update.zip is an entire rom. Sometimes it is just a kernel sometimes it is just a theme and sometimes it is a whole rom. If you install nextheme through update.zip it will not be overwritten by a kernel update.zip as they are modifying different things

    Once you install the update.zip you can delete it from your SD card. So put NexTheme on your SD card, install it, delete it, put the OC kernel on your SD card, install it, delete it.

    If you have Clockworkmod Recovery you don't really have to install anything as an update.zip

    I have a folder on my SD card called "ROMS" with tons of stuff in it, including a folder inside that called "Kernels". That way I have all that stuff saved and available on the card whenever I want it. You just have to select "Install zip from SD card" and then select the zip you want to install.

    Doesn't matter. If you do have an update.zip and you have CW recovery you might want to delete it though. The d-pad on the Droid is already a bit fiddly for those with large fingers and you can accidentally apply whatever your update.zip is if you aren't careful while navigating the menus in recovery mode (I have done this before).

    hi all!!!!
    just kidding on the beating part... I just rooted a few days ago so far i have been lucky with my installs such as cyanogen and or virtuous roms
    i have ended up with virtuousus Roms they are more sense like
    i recently installed set cpu and down loaded a chevyno1 overclocking kernel ...here is the issue...i installed from my sd card and it appeared to install ok it usually reboots automatically but today it went to the clockworkmod recovery screen and i was forced to reboot manually so i did, and upon the device restart it gets to the HTC incredible screen and hung up, never to continue... usually it continues on to and htc quietly brilliant screen then onto droid bootscreen, NOT TODAY...so after 30 minutes of waiting i pulled the battery and rebooted and recovered pwr and vol. Down into clockwork and restored from a back up...What could be causing it to never get passed the initial power up screen...and are there any tips you can offer me Do i need S-off to overclock? and what else can i try...thanks for the help

    if the kernel was the latest thing installed and the ROM was stable before this, it seems like classic instability in the kernel. not all kernels work for all phones. and high temps and reboot loops ate signs of it. you could try a different speed kernel or a different voltage or a different brand.

    my tactic is to load 2-3 kernels on my phone, that way, when/if 1 kernel is unstable, you can reboot right into recovery and try another.
