[Hero CDMA Android Development] JB in AZ:
Hi guys, I'm using Fresh 2.3.3. I haven't been on this thread in a few weeks since flashing DarchKernelv4 710 with Free Memory Tweak for Fresh 2.1.1/2.1.2/2.3.3 and using OC Widget set to 710/245 Screen on and 480/245 Screen off. My Hero runs perfectly...no slowdowns, no FCs, no reboots...I say "GREAT job!" to all involved! Thanks for making my Hero faster than a stock EVO!!! (or it seems that way, anyway!...perception IS reality, right? )

Now I have helped my son root and rom his Hero to Fresh 2.3.3, and want to OC it. Having read the complete thread, I am confused by all the recent changes, and the module remover..etc. So a couple of questions. :confused:

1. Is the zip file I mentioned above, (found in the first post) unchanged from when it was first posted here?

2. I know when I downloaded it said "tested" now says .."some bugs..." but, as far as I can figure from the thread, it should be OK if used with the OC Widget, right?

3. Do I need to run the remover if my son's Hero has never had a custom kernel on it? Not realy sure what the remover is for.

Thanks for helping! To me, this is the greatest part about the Android OS, the great community that comes with it! :)
[Hero CDMA Android Development] Noblesse:
Yeah, but how hot does yours get? And how is the battery life?
[Hero CDMA Android Development] c00ller:
Yes, it is unchanged. It's the same file.

Ever since the whole free memory killer was introduced, people have been having problems, some even on versions without the free memory killer. urushiol mentioned in a previous post that he believes he may have made a small mistake in all versions of the kernel. I wouldn't worry about it, I've heard nothing but good things from v4 users.

Yes, urushiol stated somewhere you should always do this before flashing one of his kernels. It just makes absolutely sure that the new kernel doesn't conflict with old files.

Couldn't agree more :D
[Hero CDMA Android Development] JB in AZ:
I don't notice it getting too hot, but then I live in the desert, so everything is hot here, all the time! LOL If anything, it gets hotter when charging then when using it, so I guess this is OK.

My battery life is the best it has ever been since I bought the Hero in Oct 09. I tried many Roms/kernels, and this is the best combo yet. I use the Hero moderatly, (I know, hard to quantify this), charge it up every night with the phone off, turn it on and unplug the charger at 6AM, and always get to 10-11PM with about 20-25% left. Works for me.
[Hero CDMA Android Development] JB in AZ:
c00ller, thanks for the quick and detailed reply!

Ok i did what the directions said to a "T" and when i click reboot it freezes on HTC screen. What am i doing wrong.

I have Stock .5 rom rooted
[Hero CDMA Android Development] Papa Smurf151:
R u using the correct kernal. Make sure u know which Tom ur using and pick the correct kernal acordingly. Each one has a different ramdisk that for each rom.
[Hero CDMA Android Development] Papa Smurf151:
Hey any chance of getting a 710 oc/UV no freememkiller with the ramdisk modified with the correct file to use Collin_Ph battery tweak. If not I'm gonna attempt latter tonight but I haven't messed with boot.imgs before
[Hero CDMA Android Development] Decad3nce:
Just add this into the ramdisk - init.rc:

# Include extra init file
import /system/etc/init.local.rc
[Hero CDMA Android Development] Papa Smurf151:
Yeah I'm gonna try tonight but I'm sure I'm not the only person that wants the added file into the ramdisk and considering this is the somewhat official place to get the kernals I thought I throw it out there.

I grabbed the windows version of android kitchen last night and in there I can open up the boot.img and get to the ramdisk without having to go into Linux.
[Hero CDMA Android Development] Neo31697:
Standard_vUV2_710.zip

thats the one that i am using.

sorry new to rooting and have been spending weeks reading up on it trying my best to intake it all
[Hero CDMA Android Development] dvdqnoc:
I have the 768 MHz vUV2 running with nfinite's deodoxed stock ROM, but it always sits at 245 or 480 and rarely goes to 768. What is this? Goodness my phone is as slow as molasses! Even when I uset setCPU, it still goes below what I set as my min... how to I fix these issues?
[Hero CDMA Android Development] dondadah88:
That means your phone can't handle 768.

I overclock computers and justbecause you cab go higher doesn't mean performance will increase.

I had an i7 that hit 4.7ghz on water. But no matter how cool I got it and tweak the os, 4.6 was its the best clock for that CPU.
[Hero CDMA Android Development] c00ller:
I don't think this is the case for dvdqnoc. If the phone can't handle 768 it should still say it's running at 768, but would maybe freeze or random restart. It sounds like SetCPU isn't really letting him even control the frequency. In SetCPU, try hitting menu > Device Selection > Autodetect Speeds Recommended and see if that fixes it. Might also be a superuser permissions issue? Are you using Superuser 2.2.2?
[Hero CDMA Android Development] dvdqnoc:
In fact, my phone does run at 768 sometimes, and it is very speedy during those times. The only problem is, whenever it randomly kicks down to 245 or 480, it is slow as a slug.

Whenever I open SetCPU, it says "No root access detected. Are applications allowed access to root? Operating in read-only mode." and does not let me give it Superuser permission. I dont know why. I do have USB Debugging, and I do have root access (I can boot into recovery anytime I want). My Superuser is v2.2.2.

Just for the record, other root-requiring apps (i.e. Wireless Tethering) cannot get Superuser permission either.
[Hero CDMA Android Development] c00ller:
That's the problem right there. Get Superuser 2.1. It solved my issues with SetCPU and AutoKiller. Also, my wireless tether for root users is working perfectly so who knows, it might fix that as well.

I would love to be able to use this too, but im not sure where to begin to add that into the ramdisk
[Hero CDMA Android Development] Telgar:
Before each flash I flashed the remover. I flashed vuv2 710 using fresh 2.3.3 and it was very slow. I recall another post mentioning that it wouldn't remember the OC speed setting, for me it would jump around a lot between values and was generally unstable. I flashed the v4 710 and it's a dream. I was using the same v4 710 on fresh 2.1.2 (the one right before 2.3.3).

What's the word on updates for the vuv2 kernel's?
[Hero CDMA Android Development] Androidious:
Telgar, I did have issues with V2 of the UV2 kernel (with memkiller), but I beleive that was due to not flashing the ModuleRemover.zip prior to each flash. Once I did that, and updated my OC app (tried both with and without) I had no issues. BUT, every now and then, my phone would randomly reboot iteself. This was maybe a once a day occurance (If that). I just flashed the UV2 without memkiller version (at least it doesn't mention memkiller in it's title) with hopes that it'll take care of any issues, but we'll see :) I still feel like v4 (even with the slight lag) is overall safest to use (just my opinion though), but I'm giving the new UV2 kernels all that I can give in high hopes that one of them will work well without any issues.

Good luck

MMk, I believe the issue lies with the UV2 (without memkiller -- Standard_UV2_710.zip). I flashed it appropriately and it's giving me issues (speeds move around like crazy, freezes my phone up etc...) couldn't even get into anything after the initial boots it was sooooo laggy). I think that particular file is jacked up, in my opinion.
[Hero CDMA Android Development] chromiumleaf:
FYI for many people here....undervolted kernels can lead to a LOSS of performance on some phones. UV kernels are better for battery life, but not every phone can perform better at UV frequencies. So some of you may notice your phone running SLOWER on a UV kernel even though it's overclocked. !!!!This doesn't mean anything is wrong with the kernel!!!! It just means your phone doesn't perform as well at undervolted freqs.

See this thread here for more of the technical info on it: http://xdaforums.com/showthread.php?t=697286
[Hero CDMA Android Development] Androidious:
Thank you ChromiumLeaf for your input. I actually thought my phone ran faster with the uv kernel than it does with the normal kernel IMHO. But, to each his/her own phone and set of issues.
[Hero CDMA Android Development] metal666fukhead:
I'm using vUV2 768 with mem tweak and no problems what so ever! every phone must truly be different...the only time I ran into problems is when I enabled jit
[Hero CDMA Android Development] metal666fukhead:
Can anyone tell me if v4 is an undervolted kernel or just vUV because I'm currently using vUV2 768 on nfinitefx's stock.6 odex rom and getting great battery life but I see that the v4 691 has all the bugs worked out and am thinking about switching but I don't want to sacrifice my great battery life
[Hero CDMA Android Development] hexskrew:
@ the O.P./kernel maintainer - I would like to request a fix *if anyone else is having these issues* for A2SD compatibility/setup. It has come to my attention that if you use your rom in a kitchen, it will not patch in cm.filesystem.ready=1 automatically because it sees the other A2SD commands, and then it can cause boot loops with A2SD for people not using EXT partitioned sd-cards. I do not think there would be negative consequenses from doing this.

Thank you for the kernel BTW! Great stuff! *I am on 720mhz as well as in my rom (SouthPaw!V1.5-final) and none of my users have had ANY problems with it besides the a2sd issues (which I don't feel is your fault or anyone's really btw)
[Hero CDMA Android Development] oldjackbob:
Special request

Urushiol, I have a request.

I absolutely love your UV_691 kernel (it has completely cured any tendency of my phone to freeze on boot), and I'd use it exclusively, except that my phone's GPS module doesn't function reliably when undervolted. I use several different GPS tracking apps, and they all perform admirably except when I'm running a UV kernel -- every one of them has a problem recording a continuous one-hour track if I'm not running full factury voltage. So I've determined that it isn't a software problem, but rather a hardware problem...I simply can't reliably run UV if I want to record a GPS track.

But other than that one single issue, my little Hero loves UV!

So here's my question:

Would it be a huge effort for you to fashion a switch of some sort, such that a user of one of your UV kernels could somehow switch between undervolting and full-house voltage? Because the only time I need full voltage is when I want to record a GPS track, but I'm shackled with having to run a v4 kernel to reliably do that. It'd be great if I could run a vUV2 kernel and just have the option to disable UV on those occasions when I need full voltage.

Would it be a great deal of effort for you to somehow make UV a switchable on/off feature in your UV kernels?

Thank you so much for the great work you've already done for us, urushiol!
[Hero CDMA Android Development] pbp776:
I'm not sure if this even possible. The reason I say is once the kernel is build you can't modify kernel setting without rebuilding the kernel again. I'm might wrong here. As I'm newbie my self in Kernel.
[Hero CDMA Android Development] Outer Marker:
Cooller, have you tried superuser 2.3? Does that fix the problems with superuser 2.2.2?
[Hero CDMA Android Development] c00ller:
I have not tried superuser 2.3. I am running su 2.1 as 2.2.2 gave me problems with both SetCPU and AutoKiller. Ever since trying 2.2.2 I've been disinclined to try newer versions of superuser unless others verify there are no problems with apps that need su permissions..
[Hero CDMA Android Development] Outer Marker:
Just in case anybody was looking for some validation, I upgraded to Superuser 2.3 last night. I've been running for a full day now, and Autokiller works again. I have not tested setcpu as I use overclock widget instead. At any rate, give Superuser 2.3 a try... icon has changed and is now an android pirate, not a ninja scuba diver...
[Hero CDMA Android Development] pr0ject:
I was just wondering what are safe temperatures for the hero, i get it going pretty hot...
[Hero CDMA Android Development] metal666fukhead:
How do you upgrade superuser?
[Hero CDMA Android Development] metal666fukhead:
The back of the battery says 60° celsius is the limit but I don't think I'd want it to get any higher than 50...the hottest my has got was I think 46 or 47° and I was freakin out

Does anyone know if any of these will work on the stock .6 rom or if there are any overclocked kernels for the stock rom? Thanks for any help
[Hero CDMA Android Development] dsMA:
why wont all kernels flash properly?

Hi Guys

I am not here complaining; I want to understand why only some of the kernel versions will flash properly.

I am running Aloysius 2.1.2 with update 6-29. I have been told that it is based of the damages (damage control) rom and that I should use the kernels that are listed for it. I tried all of them but the only one that would boot properly was the uuv2_710. I know none of you can see my phone so speaking specifically about it would be prob impossible but maybe someone could speak generally about why the other damages kernels might not have flashed properly? I mean to me it seems like if one of the kernels based on that rom works they all would especially ones that are set to lower default speeds i.e. 691

Note I did flash the module remover.
[Hero CDMA Android Development] ruizma:
Do we get updates for these kernels??? PLease?
[Hero CDMA Android Development] tailsthecat3:
Youre a genius.

What would it take for me to get a kernel that... the cpu would be at 691mhz 100% of the time- from the second you power it on until you power it off...no throttle, no on demand, no set cpu, no memory management, stock htc voltage?? I dont have linux on my computer. Is there any way that I can make this using a tutorial? Or perhaps, a genius dev could whip one up for me?

What id really like is this kernel posted here:

http://xdaforums.com/showthread.php?t=750170

...with the cpu would be at 691mhz 100% of the time- from the second you power it on until you power it off...no throttle, no on demand, no set cpu, no memory management, stock htc voltage...

zens kernel is desireable because of the lag free lock screen...

thank you thank you
[Hero CDMA Android Development] fixxxer2008:
so is there a big memory leak with these kernels then?
[Hero CDMA Android Development] mrchedda:
NFX Hero 2.2.1

Will this kernel work w/ NFX Hero 2.2.1 ROM? Sorry, I'm kind of a n00b. Thanks guys!!!
[Hero CDMA Android Development] theimpaler747:
Yes, it should.
[Hero CDMA Android Development] cbarth3:
any updates to these kernels as they still list possible bugs?
[Hero CDMA Android Development] c00ller:
Not that I know of. You're best using ZenKernel

http://xdaforums.com/showthread.php?t=750170

as it is bug-free and works for pretty much any Sense-based ROM. It just doesn't have built-in memory management, but that can be done through AutoKiller, which is free on the market for root users.

I am looking to overclock my sprint hero, I am running Fresh 2.4 and I dont see a kernel for 2.4 what one should I use, the 2.3? Or is there another kernel that will work for Fresh, like the post above mine. I dont mind having to use autokiller

thanks
[Hero CDMA Android Development] theimpaler747:
I would just use the 2.3 kernel, it should work fine since fresh 2.4.0 was a minor app related update.
[Hero CDMA Android Development] DemonRagna:
I'm using NFX-Hero 2.2.1.update1 Deodex, I'm not sure which to use. Sorry I'm real noob when it comes to kernals.

Do I use this one "Darchkernel vUV2 710mhz for roms using 2.1 RUU ramdisk"

or "Darchkernel vUV2 710mhz with freememkiller tweak for roms using 2.1 RUU ramdisk"?
[Hero CDMA Android Development] theimpaler747:
I would use the first one... not a huge fan of kernel built in memory tweaks, I like to do it myself :p
[Hero CDMA Android Development] DemonRagna:
Thanks for the help. :)
[Hero CDMA Android Development] theimpaler747:
No problem, let me know if you need anything else :D
[Hero CDMA Android Development] cordell12:
Tried it and its working fine! Thanks :) I chose the 701 rather than the 768, thinking the 710 will be more stable, no?
[Hero CDMA Android Development] theimpaler747:
Most likely, unless your phone can definitely handle 768.

Ive been using this kernel for awhile now and really enjoy it. Is there any way I could modify this kernel, Darchkernel vUV2 710mhz with freememkiller tweak for roms using 2.1 RUU ramdisk, to include usb host mode outlined on this page http://adq.livejournal.com/95689.html ?

Fresh Rom 2.1.2 - vUV2 710mhz - unstable

Setup:

Darchkernel vUV2 710mhz for roms using 2.1 RUU ramdisk*

AutoKiller

Very unstable sluggish to the pint of nonuseable.

Had to go back to vUV 710mhz.

One thing I noticed is that my Free Ram was only 19mb (SysMonitor) where as it is normally around 60mb free and making changes to AutoKiller seem to have no effect, so it looks like a memory management issues.

(I did the remove.zip as instructed)

My Solution:

Fresh Rom 2.1.2

ZenKernel-HTC-08122010 no perf lock - xdaforums.com/showthread.php?t=750170

OverClock Widget

AutoKiller

This is the smothest my Hero has ever run... awsome!

Note: Becasue of the remove.zip file location change, I did my nandroid restore to take it back to prior to the .ko file move.
[Hero CDMA Android Development] cordell12:
I am,currently running Fresh 2.4 with the,710 of ,kernel. I want to go to the 768, can I just,install it or do I run the module removed first?

[Hero CDMA Android Development] Neo31697:
here this is the one that i use
[Hero CDMA Android Development] fifedogg:
I wiped and reinstalled 2.09.01 and then rebooted into recovery and installed this Kernel. I was having some lag though... I tried everything but it would still have a little bit of a lag in sense going page to page and scanning through my apps.

I have since went back to DamageR 5.0 (DC 2.08.01) and it is lightning fast.

Is 2.09.01 the reason for being slower or is it because of the Kernel itself? I dont remember any lag at all when I was using the original OC kernel just FC's on incoming calls.
[Hero CDMA Android Development] Elvesofdarkness:
My phone can be overclocked to the 768 fine and run stable but you still might be able to pull 4+ but the big thing is enabling Jit. That makes me go from 3+ to 5+ mflops but when you enable it causes instability and fc's on apps. I have been lucky and haven't had probs with Jit being enabled. I am using this kernel on Aloysius 2.1 and Pure hero and have tested both and I don't know if its the kernel making jit run more stable or what yet. I know I always had problems receiving calls, like even when I answer there is a couple second lag before it actually answers flashed this kernel and im talking to the person before the screen can even switch over now.
[Hero CDMA Android Development] markus_del_marko:
Been testing this kernel all day and i noticed not only alot of lag but the phone take a few seconds to wake up. I flashed this over fresh. :(
[Hero CDMA Android Development] Jus10o:
Its something in the kernel source for touch input. Its fixed in toasts release, but in darchdroid he had to do something to get it to work in AOSP. This kernel is based off of darchs kernel so its why it lags on wake up. Its not actual lag, just not accepting touch input fast enough before you try to unlock it.
[Hero CDMA Android Development] someonenewhere:
HoneyBuns ROMs? is that for any ROM?
[Hero CDMA Android Development] urushiol:
These are honeybun roms =)

http://forum.androidcentral.com/htc-hero-roms-hacks/14674-honeybun-v1-based-off-official-ruu.html

EDIT: UPDATED FIRST POST

Darch hooked us up with a revised kernel that includes touch screen delay fix and fixed CPU frequency table. You can now use all avaliable frequencies! (though I wouldn't recommend using any thing below 245!) and Jus10o was nice enough to make us flashable zips!
[Hero CDMA Android Development] someonenewhere:
ooohh no wonder...I'm not a member of Android Central or else I'd know about it....

I flashed the HoneyBun Kernel and it seems to be working pretty good on the nfinitefx45 Stock ROM .... no issues at all...
[Hero CDMA Android Development] vidsid:
V3 isn't working for me in the nfinite ROM. Once I get to the lock screen the phone re-boots. I notice 'toast' in the new name. Did you default the new version to anything above 710? That's caused problems for me in the past similar to this.

I went back to the original "fixed" OC. I don't use tether, so I can't comment on that.
[Hero CDMA Android Development] urushiol:
Try using the one for honeybun, and see if that works, can you post a logcat of your bootloop? Default should still be 710, darch do you know if it would have been changed?

And the name was simply a typo-ish thing. It was late, and I was exhausted, should have been darchdamagefresh, not darchdamagetoast =D
[Hero CDMA Android Development] fifedogg:
So far so good. Since I have installed this new kernel everything seems to be running well on 2.09.01. There is a lil lag when the power button is pressed until the lock screen comes up but besides that it seems to be running pretty fast. Well see how it works out...
[Hero CDMA Android Development] Androidious:
Yes, there is a bit of a lag when hitting the Power Button until lock screen comes up still, but otherwise, the kernel is just perfect! Nice work again on Darchshizz #4 bro-ski :P
[Hero CDMA Android Development] fifedogg:
Yeah no big deal. It seems to be working just great thus far :D
[Hero CDMA Android Development] vidsid:
I'm going to be tied up for a couple of hours (where I'll need my phone) but I'll do a logcat asap sometime this afternoon.

Big props to darchstar for this and all his hard work thanks man,really appreciated.
[Hero CDMA Android Development] fifedogg:
I've tried multiple settings with no change. I'm now 748/652 on and 245/160 screen off. Its not a bad lag I was just used to how fast 2.08.01 was. I'm already used to it... I'm liking how this is running now :)
