How do you all pick a kernel?

I just flashed BB.3, seems pretty sweet btw and did a full data/cache wipe just so I knew it was a clean install. I thought I'd try some 1.2 and 1ghz kernels.

P3Droid Kernels
http://chevyno1.richstevenson.com/froyo/4.2/kernels/

I mostly tried a bunch of p3 ones, 1.2,1.1,1.0 normal voltage, 1.2,1.1,1.0 low voltage, tried some ulow ones, all of them wouldn't even book. I then tried a bunch of chevyno1 kernels, none work either. It just keeps boot looping, never even getting to the lock screen.

When using 2.1 I was using some 1.1 ghz kernels and hey worked fine. Did I just flash it wrong and I was hosed from the start? I even flashed a 800mhz one and that didn't even work. I ended up doing a restore and it works fine now.

I just take a kernel, rename it to update.zip, reboot into recovery and apply, correct? I wiped cache sometimes; did I do it wrong!!??

Is it possibly my droid can't handle the higher clock speeds on 2.2?

Thanks

how do I choose it? the fastest one with the lowest voltage, which in my case would be chevy ulv 1250

I started with P3, and then moved to Chevy's kernels after hearing great things about them.

I put them all on my sdcard (in my ROMs folder).
Using ROM manager, I select "Install ROM from sdcard"
I navigate to the fastest of the ULV kernels (1.25 ULV) and install it.
If that has issues, I move to the 1.25LV...then to the 1.25 MV etc etc etc until I find one that my phone likes. Fortunately for me, my phone runs great with the 1.25 ULV.

It's a good idea to put several on your sdcard in case you go into a bootloop...then you can just boot into recovery and install one from there.

Good luck.

Hmm, sounds good. So, my droid could possibly just have trouble with anything over 1.1ghz. That's not totally out of the question, correct?

Perhaps I just messed something up since I had to do a restore and not even a P3Droid 800mhz kernel should work. Guess I'll try again tomorrow.

Obviously I could try the fastest one, but as Pete said in the OP.. some peoples may not even be able to do 800mhz.. eh?

Yeah, unfortunately not all Droids are built the same...some can handle higher speeds and lower voltages, some can't. I would try it with the 800mhz kernel that comes standard with the ROM first...it's pretty snappy with that one...then after you know that one works, you can experiment a bit and try some others that let you clock a little higher.

thanks..

Thanks for the thoughts.. I do like the 800mhz one, seems to run pretty well so far; just figured, "hey, why not go higher!" guess.. "because battery life could suffer" We'll see.. I'll try some more tomorrow..

yup

I was just thinking he was purely going for battery life.

just try a couple and see which ones work the best with your phone and rom

i have tried P3, chevy low voltage, and kbit

all three have worked just fine

it does seem like chevy low voltage 1.25 worked the best for performance, and temperature for my phone

i have it set for 550 min to 1100 max while the phone is being used and is slick as snot, not one issue or reboot

well..

I couldn't get any of the 250mhz min p3droid kernels to work; i heard things about the 125mhz min ones can be unstable, I tried them anyways and the 1200 worked but would reboot; so far the 1100 125mhz min low voltage P3droid kernal is working.

What ROM are you running? Froyo or Eclair

If Froyo, then I'd recommend one of Chevy kernels. I would start with a LV kernel of 1.0GHz. If no reboots, then try his ulv kernel at 1.0GHz because lower voltage usually results in longer battery life and less heat build up.

I agree that 125MHz can cause stability issues for people who don't have the paid application SetCPU that cause $1.99 because you can't adjust how low the CPU runs when the phone is sleeping. SetCPU allows you to control how you phone reacts in several different scenarios, so it would matter if the lowest slot on a kernel is 125MHz because you can tell you phone to never use it.
