Root overclock and suggested Kernel

S

shallow runner

Newbie
my phone is the original Motorola Droid. I used the one click option for rooting yesterday and all went well. I also, prior to rooting, updated to FRG83D. I am going to overclock the device, which was the main reason for rooting along with tethering, and was curious if anyone has any suggestions for the Kernal to use for this given the device and update? Also, I have never overclocked a phone before and can't seem to find a good guide on doing this so any other suggestions are appreciated, don't want to kill my battery life or phone. I plan on getting Setpcu from the market for the overclock. Thanks.
 
I suspect you'll not get a ton of replies since this question has been asked so many times, all the info you want already exists here in the forum - might just try searching on the related topics.

as well, you will see that kernels that work for 1 will not work for another, they are very finicky and very phone dependent - so 1's results may not work for you.

that being said...

1. you will want SetCPU app
2. research different kernels as many to select from and then speeds within the maker as well
3. you can pretty comfortably start with a 1ghz of some maker as these phones are pretty proven stable at that speed.. above that and who knows for you and your phone
4. get ready for trial and error, just the way it is with kernel testing
5. download 2-3 onto your phone so if one fails, you can boot into recovery to load another quickly and get out of the bad kernel. If you have to ask about booting into recovery, your not ready to kernel test yet ;)

good luck, search around, tons on you questions you asked exists
 
Thanks for the info guys. I think having so much info on a forum is the double edged sword of a forum. I did a search and found so much that it was difficult to sort through (going through lines and lines of replies and threads) to get the desired info. Also when doing this you find different methods, some of which contradict others and so on. I figured I wouldn't get muck info as I was sure this had been ask a million time but I got what I expected and hoped for. Thanks again.

I assume what you mean by booting into recovery is the holding of the x key while powering on to load from the SD card like when I forced the last two updates correct? (X--> power--->volume up--->camera). Thanks again.

That is how you boot into recovery, but it sounds like you still have the stock recovery installed. Download ROM Manager and flash ClockworkMod Recovery. It can be finicky (I get SD card mounting errors in Clockwork often) but it's VERY robust and allows you to install ROMs/kernels/mods/etc without having to rename the files to update.zip.

does this change the procedures for recovery mode?

The X-Booting is the same, but from there you just get an menu interface with several options of tasks to perform. You don't see the exclamation point and you no longer need to hit volume up + camera button. You're pretty much handicapped until you install a different recovery, you'll see what I mean. Most recovery tasks can be initialized from within ROM Manager as well, which is convenient.
 
Good plan. Some kernels might not be compatible with your phone/certain ROMs so as LockNLoad said keep some different types of kernels of differing speeds/voltages on your SD card so if installing one kernel sends you into a bootloop, you can easily X-Boot into recovery and install a different kernel to fix the problem.
 
OK, perhaps a stupid question and I can't find the answer on the forum so here it goes. I have saved several different Kernels to my phone (Slayher (1000 and 1200) as well as chevyno1 1Ghz low V). All are either update.zip or zip files. Do I simply unzip these to an install application and run that or is it done through the same method as forced install of updates? (power > X)
 
No unzipping required. You have two options, either open ROM Manager and select the "Install ROM from SD Card" option and select your kernel and this will automatically initialize a reboot into recovery to install the selected kernel.

The other option is to manually reboot into recovery (Power + X), then select Install zip from SD Card > Choose zip from SD Card, and install that way.

I tend to go the manual route, but either way should work. If you get a "Cannot mount SD Card" error message it's probably not anything you're doing wrong, just try again as ClockworkMod Recovery is prone to occasional mounting errors for some reason (I have a 32 GB SD card and I think for some reason the bigger SD card amplifies the issue).
 
OK, well all is up and running. I am loaded with the Slayher Kernal 1000 and have setcpu going. If anyone has any good settings for optimizing performance while not killing my battery let me know. my current seetings are as follows:

Main screen:
max: 1000
min: 250
Scaling: on demand
set to boot selected.

Profiles:
cpu>50
 
I dont bother with temp settings anymore.

Charging 800/250
Screen off 400/250
Battery <30% 800/250

I set the screen off to 250/400 incase I am dowloading something while I am not on the charger. 400 for <35% seems kind of low. Your phone will be pretty buggy for a long time. I don't worry about being below 800 since I can easily make it though a day with this set up.

All my settings are "interactive" Your charging AC max will be 600 even though you set it to 400 because of the kernel. 600 is as low as it goes when charging AC.
 
Ok guys I have the answer to all of this. There will be no need to make another thread about overclocking on this phone and any other phone with the omap processor. Its called the milestone overclock app. All you need is to use CM and be on the stock kernel for that rom. There is no kernels needed, no boot loops and no need to even go in recovery. I am using it now and its way better than having to test different kernels, get out of boot loops, testing battery life and temps, etc.

You can also set your voltage in this app so it truly is that good.

Here is the link to the thread discussing it and at least read the ENTIRE op before you do ANYTHING!!!!!!!!!!! LINK :D

Edit: If you want to use this on another rom just ask a question on that thread. There are a lot of people watching that thread that know the ins and outs of using this app. Being a member is required though.
 
OK, well what would be the difference in the non charging settings using interactive vs on demand?

Also, and insight into sampling rates, etc on the advanced tab?

androidlover14, thanks for the info but as I have this up and running I am going to give it a chance; good to have a plan B though.
 
@ androidlover14, I fear that although the method you posted does seem to be the sweet deal, it still is not the 'end all' or 'one size fits all' that you have alluded it to be.

And trust me. I have read the whole thread, and tried it but personally had some issues with it (force closing, boot loops) and that is why I am for now back to the old school method.

On the other hand, just to be fair to you with my rebuttal of said method, I haven't read it in about a week or so, and as fast as things can get changed with our phones, my impression may already be outdated, lol!

Actually, I like testing different kernels, etc. :) That's part of the fun of being empowered by root. Besides, I've found a quirk or two in nearly every kernel I've tried. Be it an issue with the governor, compcache, swap, temperature sensing, etc., every kernel seems to have a shortcoming or two. It's all a matter of finding the one that gives you peace :) Neall
 
OK, so I have made some adjustments to my settings and so far the battery life improvement has been great; I typically have at least 60% left after being off charge for 12 hours. However, I haven't noticed any real changes in speed, and in some instances there seems to be a lag; such as when opening a program (i.e. text/Facebook, etc) and even when changing between screens. I have heard that the sampling rate can effect this; any insight as to a good sample rate? Minimally it is nice to have increased battery life but the purpose was for faster processing.

Main screen:
max: 1000
min: 250
Scaling: on demand
set to boot selected.

Profiles:
cpu>79
