Phone just came off the charger so the battery usage doesn't apply just yet but I checked the second part and found nothing out of the ordinary either.

My awake time is normal too. I just reflashed this rom right before flashing this new kernal so I don't think that is the issue either. I will see how the phone lasts today and see what happens since everything looks fine.
[Hero CDMA Android Development] chromiumleaf:
One other thing I just remembered is to wipe your battery stats in recovery. And if you haven't done this in a while, you can re-calibrate your battery that way.

When the phone is fully charged, wipe battery stats from recovery, then let the phone stay on until it completely dies before plugging it back in. That can sometimes fix annoying batteries that haven't been calibrated in a while.

Oh, and since you're on DamageControl, you could try resetting all the options/settings in DConfig to default. But if you haven't ever opened or messed with DConfig at all, then don't worry about doing that because they will already be at default.
[Hero CDMA Android Development] azr6:
I have never calibrated my battery so I don't even know where to start with that. The battery always kept a decent charge before all these changes but maybe it does need a new calibration. There a simple way to do that?
[Hero CDMA Android Development] chromiumleaf:
Yes, my previous post was telling you how to do that...

I just updated to Fresh 2.3.3 and have been wanting to OC for a while now. I followed the instructions here for standard vuv2 768, nandroid backup, wiped everything, flashed module remover and then flashed the kernel and followed that with flipz vanilla lock v2. Now i went to reboot and I've been stuck on the green HTC white screen for a half hour now. Any suggestions?
[Hero CDMA Android Development] c00ller:
In this situation, previous posters have said to just take out the battery and try booting it again. If it still doesn't boot, try the 710 or 691 MHz versions. You can always up it after it boots to 768 with OC widget or SetCPU anyway.
[Hero CDMA Android Development] azr6:
Phone seemed better today but I will give this a try also. Thanks.
[Hero CDMA Android Development] MrGreg:
Well I gave vUV2+freememtweak with Fresh 2.3.3 another shot. I ran the ModuleRemover and then flashed the kernel. So far so good, the phone is nice and snappy. It's been about 12 hours, hopefully this will continue without any hiccups! Thanks for all the great work!
[Hero CDMA Android Development] blogness:
Thanks c00ller, worked like a charm with 710 :D, now for battery life testing. Thanks again.
[Hero CDMA Android Development] Outer Marker:
Anyone? Just want to make sure I have the procedure right...
[Hero CDMA Android Development] Chrizmas:
The full wipe would have removed everything. You'd want to load your rom then module remover then vUV2 kernel followed by the vanilla lock update.
[Hero CDMA Android Development] Whosdaman:
Does anyone have a mirror for the moduleremover?
[Hero CDMA Android Development] foolforfood:
Is there any way to get a flashable zip of the stock kernel for Fresh 2.3.3? I'm not able to update my profile or PRL and I think that it's due to the overclocked kernel. Thanks in advance :)

[Hero CDMA Android Development] gart999:
Hi all. I just upgraded to the DarchKernelv4 710mhz for DamageControl kernal after using the stock kernal. I am also using Damage 2.09.01 ROM.

After I flashed the module zip and the new kernal I am unable to get my Exchange Server email to auto show up. I have to go into the email and wait for it to synch and then emails show up. Hence, no pushing of emails is happening. Synch settings are correct in that items are to push as they arrive. Also, the calendar items do get pushed to me correctly, just not emails. Any ideas?
[Hero CDMA Android Development] chromiumleaf:
You can't update your PRL or Profile in Fresh 2.3.3 because he removed the Sprint SDSA from the build (Sprint Self Service app that allows you to update those). It has nothing to do with the kernel.

Read the section about "Removed apks" from the Fresh 2.3.3 main OP. It lists what all has been removed and how to add that back in. I believe pushing or installing the Sprint SDSA back in (then perform a reboot afterward to be safe) should fix your updating ability, although I haven't actually done this myself to know for 100% sure.
[Hero CDMA Android Development] c00ller:
I don't think this is it. I'm still using stock kernel but I manually deleted SDSA.apk and I am still able to go to Settings > About phone > System updates and the update PRL and Profile functions appear to be working properly. I believe all SDSA.apk did was provide the Device Self Service icon in the app drawer which was essentially a shortcut to said functions.

I'm curious though, foolforfood, what exactly happens when you try to update PRL or Profile?
[Hero CDMA Android Development] blogness:
So I got everything set up with the fresh 2.3.3 standard 710 with OCwidget thanks to c00llers tip, but when I was testing the battery life I noticed that my phone wasn't properly entering sleep mode ie: Up Time and Awake Time were identical. So I wiped the battery stats, drained it fully and now I've got it charging. Seems to be fine, up time = 47mins awake time = 6mins.

Now that I have that all cleared up (hopefully), I wanted to know about running Adv. Task Killer Free. Should I be using a freememkiller kernel? Or is that for those of us who don't use Task Killers?

The settings I'm running on ATK now are autokill, agressive, when screen is off. I added all processes and widgets/apps I run in the background to the ignore list so they don't get killed. This setup normally leaves me with about 65-75m free. Typically if I don't have ATK on I end up with just about all of my apps opening on their own even if I'm not using them or the phone for that matter. That usually leaves with about 17m free, which is next to nothing.

Is freememkiller better than ATK or does it not even do the same thing? Sorry if this has been answered, I'm one quarter noob and I couldn't find anything on google about what freememkiller is or does.

EDIT: I don't know if this has been touched on before but it seems that anytime I run an app that has an ad window built into it, lots (if not all) of my apps are opening. Is this common? Any fixes?
[Hero CDMA Android Development] foolforfood:
When I try to update I get a force close on com.smithmicro.DM and then nothing happens and I can't update at all.
[Hero CDMA Android Development] yamaford:
OK I've been running alot of rom's lately and I have decided to stay with sprint base roms because of the PRL verizon/sprint flip flop I do alot of. I keep the vUV2 on my SD card so I can flash it after every ROM. I just like it. Well I started building my own last night with the Kitchen based on the sprint RUU .6 and now it won't get passed the HTC screen. not a big deal as I keep my ROM on file and flash right back keeping data in place but the stock speed is torture .

Batery life is great on my rom but I can't handle the progressive slowdown. I'ts like the longer its on the dumber it gets. lol
[Hero CDMA Android Development] c00ller:
Last night I tried vUV2 Standard (no mem management) on nfinite's stock de-odex. After about 35 minutes of use my phone started slowing down really bad (which happened to be around when I started using SetCPU's profiles, coincidence?). After about 45 minutes it slowed more such that it was unbearable and I decided to uninstall SetCPU and restart. It was very smooth afterwards. After a while I decided to give SetCPU another shot, and ever since then it looks like it's been OK!

I do, however, notice that there is about 0.5 second delay between pressing menu and the screen waking up. After the screen wakes up though it is immediately responsive
[Hero CDMA Android Development] Fird:
I gave this kernel a shot and was having limited success with it, The phone became very laggy and would fail to respond for 15-30 seconds at a time.. I do know that my particular hero has one of the less tolerant processors and won't handle 768mhz, so I suspect that its not liking the undervolt at all.
[Hero CDMA Android Development] house1999:
For those of you that have had unresponsive phones after a while, do you happen to be using the big HTC clock widget with weather and checked full screen animation? For some reason when I use full screen animation, the phone would become basically unresponsive after a while. Disabled animation and no problems.
[Hero CDMA Android Development] MrGreg:
I'm curious as well if there is a reason to use the free mem tweak in place of autokiller. What autokiller setting would be equivalent to the free mem tweak?
[Hero CDMA Android Development] c00ller:
OK later again my phone became completely unresponsive. Suspicious again of SetCPU, I uninstalled it at around 11am. No real slow downs since then (but battery life seems worse). I will reinstall SetCPU tomorrow to confirm whether or not it is causing problems.

I may later try experimenting with v4 as I have heard nothing but praise from those to report using it.

Oh, and if I do decide to try other versions of this kernel, do I have to wipe dalvik after each flash?
[Hero CDMA Android Development] oldjackbob:
I'm not in any authoritative position to answer your question, but as a matter of principle I wipe dalvik anytime I flash a kernel. I may just be ignorant, but I don't see any reason not to, and I just always assumed that it assures that nothing is left "preset" from the old kernel.

That being said, I have to admit that I have no idea what dalvik is, or what it does, LOL. But wiping dalvik is just such a painless proposition that I see no reason not to if I want to avoid any issues after a kernel re-flash.

Someone please enlighten me if I'm all wet.
[Hero CDMA Android Development] djhopkins2:
I just started running into the lag issue also. After a while the phone would get very slow and unresponsive to the point where it would have to be shut down and restarted. However, i may have found the source of the problem. By the time it starts locking up i usually don't have the ability to open up a system info app but i can hit the task killer button on the home screen. By the time i am doing this phone is completely unresponsive but if it recognize the button press it speeds right back up.

This is with the VUv2 free mem killer 710 zip on the latest fresh Rom.

I thought i would mention it appears to be a memory issue. By the time i notice the lag it's too late to open up anything to check the ram. However i've noticed before the lag shows up the available ram starts dropping.
[Hero CDMA Android Development] :
I Believe the you are not suppose to use a task killer with the free memory killer versions of these kernels. Somebody with more knowledge will correct me if i'm wrong
[Hero CDMA Android Development] oldjackbob:
It isn't task killers, as such, that you shouldn't use, it's the particular app named AutoKiller that you shouldn't use. AutoKiller is a free mem killer app that does the same thing that the embedded free mem tweaks in the kernel are supposed to accomplish.

I've been using Advanced Task Killer for months now to kill any tasks when I'm finished with them, with absolutely no problems.
[Hero CDMA Android Development] c00ller:
I discovered this is the same problem that causes my lag and eventually a completely unresponsive device.. however, I am using the version of the kernel WITHOUT free mem killer. I noticed that whenever my phone became slow, my free memory would drop to 10-20 MB (using Task Manager by Apollo, auto-kill disabled). I did a nandroid restore and somehow it has been great ever since; my free memory has been steady at around 30 MB. I guess my AutoKiller preset was not good at the time.

For those of you not using the free memory killer and are using AutoKiller, what preset do you use?
[Hero CDMA Android Development] d-shade:
I am trying to get this working on a Rom I am building but it just hangs on the initial HTC screen. Can anyone help me?

I am using my carriers 2.1 which is AK digitel

I was able to use the uv kernel when using drach and zenexp.
[Hero CDMA Android Development] MSK01:
Can I use this without having a ROM on my Hero? I just have it rooted but no custom ROM.
[Hero CDMA Android Development] urushiol:
Can you post a link to the rom you flashed, I'll pull the ramdisk from its boot image and pair it with the UV2 kernel and with the v4.

btw, I am going to update the first post tonight, I'm going to add the vUV1 links back due to problems with the freememkiller tweaks by present in the zImage of vUV2. I will need darch to fix those, its above my head.

I will also fix the v4 kernels that are having problems with freememkiller and the freqency parameters.
[Hero CDMA Android Development] urushiol:
You can use any that are compatible with Nfinitefx45s roms and it should work great, just be sure and nandroid first to be certain!
[Hero CDMA Android Development] urushiol:
I believe this bug is present in all the vUV flashables, and gleaning from darchs post a few pages back, its a problem with the zImage, a tweak to the freememkiller settings inside of the zImage. The freememkiller tweak I had been implementing was in the ramdisk.

Hopefully darch can get us a fix sometime, if he can catch a break in Froyo dev'in. =)
[Hero CDMA Android Development] MSK01:
Ok, I decided to use the Honeybun version (with the Honeybun ROM installed) and I downloaded the 710 kernel. I have the overclock widget and I'm wondering what my settings should be at for screen on and screen off.
[Hero CDMA Android Development] urushiol:
You shouldn't need to use an OC an oc application for any of these kernels =)
[Hero CDMA Android Development] MSK01:
Ok, then if I wanted to change to the 738 kernel at a later date would I have to wipe everything, reflash the rom, the remover, and then the kernel?
[Hero CDMA Android Development] urushiol:
No, if you wanted to change to any other kernel the only thing you need to do is

1. Run the remover.

2. Flash the kernel.

3. Possible clear dalvik-cache if you run into some sort of problem.

You do NOT need to wipe everything or reflash your rom.

=)
[Hero CDMA Android Development] MSK01:
Awesome! :D
[Hero CDMA Android Development] zenulator:
I hate to say it but if these kernels have compcache enabled it will cause slowdowns over time. Any type of swap pretty much negates androids memory killer since it sees more memory than it physically has therefore keeping pretty much everything in memory. Compcache/ramzswap or any swap for that matter also introduces latency in kernel.
[Hero CDMA Android Development] urushiol:
Humm, perhaps I will nandroid back from darchdroid and test a bit without compcache/ramzswap and see what happends.
[Hero CDMA Android Development] d-shade:
I got it working, I used android kitchen to unpack boot.img from my rom and from the fresh_UV_710.zip I downloaded a while back. I copied the ramdisk folder and the gz file from original to the UV folder and repacked it. Put it in my rom and it booted up fine.

That is what I was suppose to do right??

I also copied the contents from the system folder in the zip to my working rom folder as well.

I figured I would take a crack at it while it was uploading.

Also is there any widget that can monitor what speed the cpu is running at?
[Hero CDMA Android Development] urushiol:
Indeed, you did it right =)
[Hero CDMA Android Development] whiteonline:
Thanks for the heads up. I disabled compcache and it made a nice improvement.
[Hero CDMA Android Development] blogness:
I gave up with this for now until its greatly improved/perfected. The battery life was very promising, about 15hrs up with 4.5hrs awake, but the slowdown totally makes it useless. I couldn't answer phone calls because the phone was lagging so bad that by the time the call showed up and it started ringing the voice mail had already picked up. The internet was completely un-navigable and as I said before any app with an ad window in it basically froze my phone to the point that I would have to reboot. I ended up going back to Fresh 2.1.2 because I have no use for friendstream and those pointless htc apps, plus it seems to run just a tad faster than with 2.3.3. Kinda sucks that these devs have turned most, if not all, of their attention to the newer phones, EVO etc, but thats just the way technology is. I'd really like to know if anyone got one of these kernels to work with fresh without having these essentially fatal flaws and if so how the fcuk they set everything up. Until then I'll tool around with removing that crap I don't need from 2.3.3.
[Hero CDMA Android Development] c00ller:
How do you disable compcache?
[Hero CDMA Android Development] urushiol:
He must have removed compcache.sh or hes edited the ramdisk one. =)
[Hero CDMA Android Development] whiteonline:
Correct.

adb remount

adb shell rm /system/etc/init.d/compcache.sh

adb reboot

If you want it back, just reflash the kernel or back up compcache.sh before deleting it, then restore. Either way requires a reboot.

Really makes a helluva difference with the UV/no mem tweak kernel.
[Hero CDMA Android Development] punkr0csux:
What is lost by removing compcache, if you don't mind me asking?

E:

Also I performed the adb procedure you listed above, my hero has been running flawlessly on ZenHero w/ 710 UV2. Thanks for the tip.
[Hero CDMA Android Development] blogness:
What kind of difference did that produce for you? Has it fixed the problem with the non-responsiveness? I really hope its just that easy... and if it is thank you whiteonline.
[Hero CDMA Android Development] c00ller:
I'm running the regular vUV2 with no mem tweak. I'm trying this now.
[Hero CDMA Android Development] Outer Marker:
I'm running the nfinitefx v4/691 no memtweak version of this kernel. Does that have compcache enabled, and can I disable it using the adb method above?
[Hero CDMA Android Development] blogness:
Definitely let us know how that works out with compache disabled. I'm curious to see if its the culprit in all this slowdown nonsense, but I'm tired of flashing reflashing nandroiding etc. its getting pretty tedious...
[Hero CDMA Android Development] KBizzle:
I know this is a stupid question but where are you guys finding the kernels without the mem tweak?
[Hero CDMA Android Development] KBizzle:
Nevermind, i found them.
[Hero CDMA Android Development] blogness:
The first post looks to have been edited recently and now it looks like they all have memkiller? Am I reading that wrong?
[Hero CDMA Android Development] azr6:
Is this in all the kernal versions? I can't find it in my damagecontrol one.
[Hero CDMA Android Development] BlaqkAudio:
I believe it depends on the ROM. I checked and Fresh doesn't have it either
[Hero CDMA Android Development] whiteonline:
I am using Standard_vUV2_691.zip and it's in there. And it did make a big difference with nfinitex rom after removing compcache.
[Hero CDMA Android Development] c00ller:
What exactly are the differences you notice? I'm using that exact same ROM and kernel with disabled compcache and I guess my phone is running smoothly but I can't say it's a night and day difference.. but it is indeed smoother and less laggy in general. Apps tend to stay in memory more and load somewhat faster. Returning to the home screen is a bit faster too I suppose.

And a question to everyone: do you use AutoKiller? If so, what preset? If not, is there a reason why not?
[Hero CDMA Android Development] id_twin:
I flashed the moduel remover, then the kernel, and wiped the davlik and still everytime you try to boot the phone up it just hangs in the lock screen (no service) and no response to touch, anyone know a fix?
[Hero CDMA Android Development] urushiol:
What is your rom and exactly which one of the 10230912384 zips in the first post did you flash =)
[Hero CDMA Android Development] MrGreg:
Hey urushiol, are there any known issues with the Fresh 2.3.3 v4 kernel without the freememkiller tweak?

Since there are some issues mentioned with vUV2 and v4 w/freememkiller, maybe I'll try v4 with autokiller. I have been using vUV2 and it seems to work fine for me other than a couple reboots, I want to see if the reboots disappear with v4.

Thanks for all the work by the way :D
[Hero CDMA Android Development] id_twin:
Darchroid 2.7

Tried flashing both:

uv2 691 (standard)

uv2 710 (standard)

Both with the same results
[Hero CDMA Android Development] urushiol:
None of these zips will work on darchdroid, you will have to nandroid back, or reflash. They are for HTC sense based roms only, darchdroid is AOSP.
[Hero CDMA Android Development] joehunni:
Good thing these are only for sense ui roms, ohh wait....
[Hero CDMA Android Development] urushiol:
Still need to get around to redoing v4.... damn life keeps getting in the way =P.

Um, any V4s without autokiller *should* be fine. If anything you might seem some lockscreen lag because I mis type the minimum frequency on some of them, and I have seem them drop to 19mhz instead of 245mhz in sleep state(though im not sure if this isn't a power saving function built into the kernel?)

Reboots should go away on v4. Will do my best to have an update by the end of the week.
[Hero CDMA Android Development] elessarelfstar:
I haven't had any success with any of the UV2 kernels for Fresh 2.1.2+ on 2.3.3.

Every time it runs awesome for a couple of hours then grinds to a halt.

My solution: I'm running HoneyBun 691mhz UV2 ON Fresh 2.3.3 and it runs great. I know its not running on the "right" rom, but it works. I also have autokiller set at 30,35,40. The best thing is that I don't think I've really overheated it once - even with nav+music or streaming tv over wifi tether. The highest temp it reaches is maybe 40 (perhaps have gone to 41 or 42 a couple of times, but its still far better than the 50 I was hitting with previous OC kernels). I like that I don't have to keep tabs on temp.
[Hero CDMA Android Development] MrGreg:
Sounds good, I'll just hang tight and play around with whatever you post later. Life is certainly busy, I'm impressed with the work you guys do!
[Hero CDMA Android Development] Androidious:
This is the same problem I find, EXCEPT, my phone will run great for the first couple mins, then will come to a grinding halt and I can't barely do ANYTHING to the thing. It looks as if it's constantly switching between the min/max settings, but can't seem to stick to one. Anyway, it ends up getting the phone so freaking hot, that I couldn't put it through that kinda stress any longer.

I think it's starting to do what it used to do to ya uroshiol.

In case u were wondering, I tried the same kernel on two different roms. I was using the Standard_vUV2_710.zip on both Fresh 2.3.3 and ZenHeroFX 2.0.

Update 9:00 AM:

Hmm, maybe this is the issue... ? :)

Update 10:30 AM:

So, I just flashed the ModuleRemover.zip and after, the Standard_vUV2_710_M.zip for Fresh 2.3.3 rom in hopes that it will take care of the massive slow down that occurs shortly following bootup. I will report back when I have some results or sumpthin. I know, this is a long and pointless post, but what the hell :P

Update 11:30 AM:

Welp, since actually following the directions as specified by Uroshiol, and actually applying the ModuleRemover FIRST and THEN flashing the vUV2 kernel for Fresh 2.3.3, I finally seem to be getting a very clean and krisp feeling while running this kernel. All seems to be running nice and smoothly. Thanks again Darch and uroshiol :) I RECOMMEND reading the recommended reading in the first post before going ahead and doing it yourself, LoL!
[Hero CDMA Android Development] c00ller:
I think the combination of removing compcache.sh and downgrading to superuser 2.1 (which allows me to use AutoKiller) has made my phone lag-free ever since!
