[Q] How to install an OC kernel??

Im trying to install an OC kernel on my NC running CM7.... but its not working. I install it and everything goes correctly, but i cannot surpass the 925 OC on CM7, even though it can go up to 1000ghz and 1100ghz.
Im using update-CM7-dalingrin-OC-sd-042411.zip from dalingrins..
The "official" OC kernel thread is here:
http://forum.xda-developers.com/showthread.php?t=925451
Not sure what to do or how the OC kernels work. He says to use CM7 settings to overclock, but the highest it goes up to is 925, which seems to be stock for that. Let me know if you can helppppp!
Thanks, Bobby

Are you installing the correct kernel for your install? EMMC vs. SD?
Are you installing the kernel itself & not the MD5 file on the kernel page?
What versions of recovery and CM7 are you using?

I installed the SD kernel, and it installed fine....but nothing new showed up.
I installed the EMMC kernel, which was a bad idea...and just didnt load up CM7.
I installed the kernel itself, and put it on the root of the SD card, flashed it, cleared the cache and dalvic, but it still says i have the stock kernel that came with CM7
I have CM7.0.2-encore...im using an 8Gb class 6 SD card.
I also tried kernel manager from the market...and tried installing the kernel that way but it literally reset my device to the stock 1.2 update with no CM7....it was wierd, so wont be doing that ever again. Im restoring everything now so ill be back to where i started. Its OC at 925 now, but cant go up any higher which means im not installing the kernel correctly....ughhhh

Ok. If you were previously running a recent nightly build you should have also wiped system & data. Also check your version of recovery. Current version of Clockwork Recovery is 3.0.2.8....What version are you using? I had tons of problems with kernels over the weekend using and older version of recovery that I was too lazy to update. I updated it and my troubles went away.

That you'll have to search for my friend. My install is to EMMC not SD and I've never really followed those processes. When you find it though, be sure to add it to your thread so that others may find the info as well.

having similar issues
I have CM7 7.0.2 installled to emmc, but everytime I try installing overclocking update I just get a blank screen after I reboot. Waited five min and nothing happened. This has happened twice so far. I have a 3.0.2.8 CWM SD and am able to rollback my nandroid after this happens. Not sure I'm doing wrong. I tried install 4/4 emmc update, do I need to install 4/24? Or is there another issue with my install? Do I need to install CWM to recovery? Tried wiping cache and dalvik cache as well before installing. Thanks a lot.

You have a slightly different problem. Is it a blank screen, or do you have an under score "_" in the top right hand corner?

Clockwork on EMMC will make your life much easier for everything. Flashing new roms, backing up, restoring, rebooting to recovery without having to change SD cards, etc...
That being said, I personally keep an sd card imaged with recovery, a rom, and gapps for uhh oh's, when I have to start over.
Follow that thread, first trying to use recovery from EMMC (if you can access it), if you can't access it use a bootable recovery sd (your uh oh card).....Some people say just wipe cache & dalvik, but the current CM7 nightlies and stable builds don't play nice when swapping back and forth.

Still dont know how to install the freakin kernellllll.UGHH>
So i updated my sd card to CMW 3.0.28, which is the newest. I downloaded the 4/24 SD kernel file and put it on the root of my SD. Backed up everything, flashed the kernel, wiped the cache and dalvic, rebooted the phone....and everything works like usual, except i still dont have the kernel apparently. In the Cm7 settings it still only goes up to 925 and in the info about the tablet it has kernel version 2.6.29-omap 1.....which is def not the one i flashed....any help?
P.S. im about to give up
P.P.S......not really lol.

Another idea....try downloading the kernel again. Could have been a corrupt download. If you've got everything backed up.....wipe system, data, cache, & dalvik then install your kernel through Clockwork (install .zip). Then make sure you allow enough time for your machine to boot fully, before you try adjusting you CM7 settings. Worst case scenario is that you have to restore your backup.

CM7 n98 and OC Kernel

Hey there everyone, I didn't want to post a thread, but from searching around, I couldn't find anything really.
I bought my nook about a week ago, and I have it running on cm7's nightly build 98, from my sd card. Is there any way to get Dalingrin's OC kernel onto my nook? I've tried putting the update file onto the root of my sd card and booting to recovery, but it doesn't work. I've been dealing with rooting/rom'ing with my captivate for a while, so I am pretty sure I didn't mess up on the flash, but I'm at a loss. I know you nook veterans get annoyed at questions like this, but I just wanted to have a place where newbs such as myself could come for a definitive answer.
Thanks to anyone who helps in advance.

To boot to recovery from the SD card after you restart/reboot, hold the "n" button down before the green Cyanogenmod splash screen shows. Instead of "loading", you'll see something like "booting to menu". You can let up on the "n" key at that point. You'll get a screen that describes what to do, but you should boot to the SD card and recovery. The OC kernel will install if you have it located on the sd /boot. This is also the way to install a new nightly or stable ROM update.
Other methods of booting to recovery, such as pressing the power button or selecting recovery in the ROM Manager after Android has booted, don't work because they expect to see the install on the emmc, not the sd.

Thank you for that, last question. If I'm on nightly 98, can I flash whatever the newest one is over my current? and will it wipe anything?
Edit: I put the 6/13 oc kernel update file on the root of my SD, selected SD and recovery from that boot menu, but how do I check if it worked?

The default CM7 kernel has a max OC of 925Mhz in the CM7 Performance Settings. The 6/13 kernel has a default max OC of 1200Mhz.

I suppose it still didn't work then :/ I'll keep trying. Anyone know if a new nightly will wipe everything I have and have set up?

[Q] Nook Won't boot after Kernel Flash?

I had my Nook Color running pretty stable using the 7.0.3 CM7 Build. I decided that I wanted to try it out at 1200 Mhz, so I downloaded the June 30th 2.6.32 Overclock Kernel. I put it on my SD card and booted into recovery. Installed from zip and wiped the cache. By the way, my install is internal memory. I chose the correct internal kernel from the list (update-CM7-dalingrin-OC-emmc-063011.zip).
Now when I boot, I get the green screen and the loading message. Then the screen flashes and it won't go any further. The unit is still on, but it's not booting anymore. What can I do to fix it? What did I do wrong?

Did you wipe the Davlik cache?

Yes I did. I ended up just flashing it again. Lost most of my stuff, but I'll get it back. I chose one of the nightly builds so that it would have the correct updated kernel already installed. So far so good. Thanks!

You got an incorrect version of Dalingrin OC kernel for your 7.0.3 CM7 ROM, OP.
Update: Get the 04242011 version

[Q] CWM problem

Good day all. I recently bought a Nook Color. I'm running CM7.0.2 along with gapps 20110613 from a 16gb SanDisk class 4 SD. When set up the apps (after enabling wifi) I got an error, due to the fact that my sucky router dropped the signal. As a result of this I was not able to download gmail, google maps, etc. My android market runs perfectly but I wanted to flash gapps so as to download gmail and the others. I went into ROM manager and updated to the latest CWM. However, no matter what I do I can't but into recovery. I tried n+power button, reboot into recovery from the power button menu, and from within ROM manager. All no go...it just booted into CM7, so I removed the SD card to boot into stock Nook 1.2 software. When I did this it brought me to the CWM recovery menu (SD card not in). Of course I could not select anything on the menu. Put back in the SD while still in the menu to try select an option but nothing. Shut it down by holding the power button and booted it back up and it went str8 into CM7. Shut down took out SD and it booted into stock Nook 1.2 software. What am I doing wrong guys? I'm trying to flash the overclock kernel and reflash gapps. THANKS

Could the reason gmail, youtube, googlemaps didn't install on setup be due to the fact that I'm not in the USA? If so I'd still like to know what the problem is so I can flash the overclock kernel.

No one has any idea? I know one option is to backup and redo everything, but I'd really like some troubleshooting ideas before.

Did you use the 1.3 image from verygreens thread? If so the old 7.0.* stables are not supported. You will need to back up and redo it either with the old image or a new CM7 version.

Yea I used the 1.3 in the thread with 7.0.2. What version cm7 would I need to use with the 1.3? 7.0.3 or a nightly,? Where would I be able to find an older image to work with 7.0.2 and what version of the image should it be?

The 1.3 image won't work with any 7.0.* versions. You should upgrade to either a recent nightly or the 7.1.0 RC. You could find an older image somewhere but there isn't much of a point as you would have to redo it all anyway so why not upgrade? Plus your battery life will improve by a lot as 7.1 RC and the nightlys have deep sleep.

As I said many times to newbie who runs CM7 off uSD that do not or should not mess up with ROM Manager. In fact, there are members also confirm that if booting off uSD, ROM Manager has no effect.
Based on what you, OP, described, you had flashed the CwM into the internal memory.
Keep your fingers crossed as I do hope you didn't screw up anything else.
Anyway, using verygreen's 1.3 image along with the latest nightly-built CM7 and the latest 06132001 gapps and boot it off uSD again. You should be fine.
Before that, fix your home wireless network first.

I decided to just go with 7.1RC1 since I wanted the better battery life. Is there a way to check about the CWM on the internal and how would I go about removing it if I did? I ask for warranty purposes ofcourse since I opted for the 2 year extended one. Also to flash upgrades and such, since you don't recomend using ROM manager then how should I go about doing it (i.e. overclocking kernel)?

1. I never have any issue related to battery with any nightly build that I've ever used. I am currently having the nb153 and it is fantastic.
2. Check CwM and how to remove off the internal memory? I don't know any quick way except restoring the original ROM.
Again, for warranty purposes, strongly suggest running off uSD
3. Updating by loading/copying/dragging the updated files onto the root folder (aka "boot" partition), then TRY loading into Recovery by:
a. combination of power/N buttons if you have skill or
b. let it boot normally into CM7, wait until completely loaded, then reboot and select "recovery" option. Keep yr fingers crossed. This is an easy method but if it doesn't work then option a is the only choice.

Sorry the battery issue was as compared to the current CM7 stable not the nightly. I got everything installed so far besides the overclock kernel. So I will try your recommendation for booting into recovery not using ROM manager.

You don't flash anything when running off an sd card you just boot into recovery and then reboot. Easiest way to get the overclock kernel would be to just upgrade to the latest nightly.

Where did my fourth vSel go?

Recently, I've noticed that the Overclock settings in the bootmenu on my Defy+ only offer three clock speeds and three Vsel settings. It always used to have four. CPUSpy shows four clock settings: 300Mhz, 600Mhz, 800Mhz and 1000Mhz whereas the bootmenu only shows 300MHz, 600MHz and 1000MHz. Is anyone able to suggest how I might get the missing one back in the bootmenu?
I'm running bootmenu 1.1.8, as installed by Defy2ndint 2.3 (thus also recovery version 5.0.3.1).
SetVsel is no help because it causes the phone to reboot. I've had a look at this thread but the "fix" seems to involve changing quite a lot of stuff, not all of which seems to be particularly relevant to the CPU speed & voltage settings. In particular, it installs multiboot which I've always preferred to steer clear of, having no need for it (I'm a boring person who is quite happy with a largely stock ROM). Mind you, the touch bootmenu does look nice, though...
I also had a look at this single posting from the extensive CM7.1.0 thread. I've tried copying the overclock.conf and overclock.sh files from that posting on to my phone, but I still only get 3 CPU clock speeds showing in the bootmenu.
Anyone got any better ideas?

This title is so funny :laugh:

Which kernel are you using?
Froyo has got 3 settings gingerbread 4

I'm on Gingerbread.
I've got to the bottom of it: version 1.1.8 of bootmenu only supports three CPU speeds. I think that's because it's part of a Cyanogenmod release which is based on the Froyo kernel and therefore only supports three CPU speeds. I previously had version 1.1.0 which comes from somewhere else - I'm not sure where. I installed it, along with CWM recovery 5.0.3.4, from a zip file via recovery, but I can't now remember where the zip file came from. Fortunately I still had a copy of the zip file to hand, and re-installing it gave me back my 4 CPU speeds.
I'm still quite tempted to try that fix for SetVsel on Defy+, though...

Now this is odd...
I installed the SetVsel fix, which included a lot of other stuff that I wasn't sure I wanted like touch bootmenu and multiboot. Anyway, it installed OK and SetVsel did work, but I decided I didn't like the rest of the baggage, and having got to the bottom of the missing fourth CPU speed in the bootmenu mystery, I didn't really need SetVsel. So I did a full CWM restore - of everything: system, data, recovery, bootmenu, the lot. And there I was, back where I expected to be...except that SetVsel still works! How did that happen?
