v.4 - GB’s Impressive Sounding Name Kernel
* As always, many, many thanks to xcaliburinhand.
* Consolidating Steam and Voodoo/CWM kernels into one thread. The two kernels are the same except for recovery, and jfs support in the Steam kernel.
* Started using a proper changelog
* Implemented Impressive Sounding Name Technology AND Dynamic Naming Technology patches; next update to include Dramatic Use of Imagery, with possible Reference to Mythical Creatures patch.
* Cherry-picked some recent commits not included in JPX source. (Will post source this evening, I hadn’t planned on releasing this just yet, but it seems as though it’s already being packaged into a ROM so might as well, right?)
* CONFIG_ARM_THUMBEE=y, enables ThumbEE processor mode, should give some minor JIT performance improvement.
* config_hz=100. With this value, kernel hz = user hz which eliminates HZ <--> USER_HZ conversions. It should also slightly increase battery life without affecting performance.
* Increased default overclock to 1280 MHz. Your may want to revise your undervolt settings, 1280MHz runs at the same voltage as 1200MHz did/does, so you **may** not be able to undervolt as much at 1280. (Yes, I previously said I wouldn’t go past 1200MHz, but, I feel ok going to 1280 since the voltage hasn’t changed and it’s still well below the max vdd_arm.) Use voltage control or setCPU to limit clock speed if you don’t want to use this. Delete your Voltage Control boot settings before booting this kernel. I’m currently using Voltage Control 3.0a.
* Added Voodoo Sound. I hadn’t really planned on it but there were a lot of requests for it.
* Removed i9000 splash screen and replaced with an old familiar one.
* Want lower screen brightness? I know Hardcore did tinkering with the kernel source to do this, but I really like Screen Filter, it even has a Tasker plugin.
* From previous versions: Backlightnotification 2.3, Voodoo color/video fixes re-enabled against my better judgment and even though single-blind testers couldn't tell me which kernels had it and which did not. .

This seems to be stable again. Started over from scratch and added in BLN 2.3. Everyone who was affected by charging problems with the previous kernels has not had a shutdown over the last two days of testing. Hopefully we're good again.
1-4-11
Closed testing on newer kernels until I'm fairly confident the issue is resolved again. I had still been getting intermittent reports of charger instability from the reoriented-balls-1-3-11-ocuv-bln23.zip (#47) kernel. Anyone affected by this please switch back to the 'f' builds below, which is the last known rock solid (I think) version.
-----------------------------------------------------------------------------------------------
This kernel is fast, and this kernel is stable. It's overclocked by default to 1.2GHz, but if you don't want to overclock at all, just install either setCPU or download xan's app which I have attached to this post and set the max clock speed to 1.0GHz. This kernel supports init.d scripts, so you have save your settings and have them load at boot.
1100-1200+ Quadrant score on RFS at 1GHz. 1500-1700+ on /data, /dbdata, and /cache on ext4. ~14.1 Linpack at 1GHz. Compare that to any other kernel available here at the same speed and I think you'll see this one comes out on top. I'm not doing this for donations, I just want to my experience with the phone as good as possible. Since this is a Voodoo 5 kernel, you can also make /system ext4 as well for an even smoother experience. This kernel has great battery life and is very stable as well. And when I say stable, I mean, you can use the phone however you want to, you don't have to do any workarounds to keep it from freezing. (edit - as long as you're using one of the build f kernels it seems...) Although, as always, if you aren't 100% satisfied with any of my products, I will give you a full refund.
What this kernel is -
Kernel for 2.2.1 ROMs, (may work on 2.2, but I haven't personally tested it), built from JPX source, with Supercurio's Voodoo 5, overclocked by default to 1.2GHz with raspdeep's code, and Neldar's backlight notification enabled, and re-oriented with xcaliburinhand's code. The undervolting code has been fixed to keep your phone from dying while charging. I'll not be supporting anything beyond 1.2GHz. I hardly use 1.2GHz myself, and from what I've read, many users (but obviously not all) have stability issues with anything much beyond that. This post from one of the senior Android engineers at Google also struck a nerve with me, and is also part of the reason I'll not support anything past 1.2GHz. Samsung actually wrote most of the code for 1.2GHz into the kernel source but had it commented out, so I don't have a problem providing software that will allow users to push it to that level.
Again, for voltage control, use xan's app. I've attached an older version of the app as I'm not sure if the newer one is backwards compatible with the 'older' methods of power management.
Also, standard disclaimers about how if this blows up your phone or tells your girlfriend she's getting fat, it's not my fault. I've had this kernel on my phone for a couple days, so none of that should happen.
How to install - Either flash in ClockworkMod, or use Neldar's really awesome kernel flashing app.
gb-reorient-12-23-build-f.zip is a zip tarred zImage. Unzip, then flash the tar with Odin, or extract the zImage and flash it with Heimdall or Neldar's kernel flashing app.
gb-reorient-fixed-ocuv-f-cwm.zip is a ClockworkMod flashable kernel.
Some thoughts on undervolting
The whole point of undervolting is to safely do the same amount of work with your CPU while using less energy (ie more battery life). Your phone is idle most of the time, so you can the most from undervolting lower frequencies more. Undervolting is safe WHEN you find the settings that work for your phone. Generally, -75mV seems to be stable for everyone. If you want to push it further, go ahead, but realize that if you push it too far, you phone will freeze, and you'll have to pull the battery. Relatively harmless, but, be aware it can happen. Personally, my phone is perfectly stable at the following settings (from 100MHz to 1000MHz) -125mV, -100mV, -100mV, -100mV, -75mV. These settings may not work for your phone. You might find that you can get by with undervolting a little more, but your system will freeze randomly, so if that happens, don't undervolt as aggresively. So, for example, I found that I can usually get by with -150, -125, -125, -125, -100, but every once in a while the phone will freeze up. And since I want a stable system, I've backed down from that. I can't tell you what to do though, but keep in mind that undervolting too much may lead to system instability.
- If you still want to try to find a oc/uv kernel which works for you, don't undervolt at all and tell me if it still happens with kernel #7 (12-23 build from my other thread). As far as I know, no one has had an issue with charger instability on that kernel. If it does still happen, I need to know the kernel version # and for good measure, the production code under your battery (can someone tell me what the name for this is again, I don't feel like shutting off my phone to check), it will be a number like 08.10, 10.10, etc.
- If even with the 12/23 build f kernels and not undervolting at all, you're still get shutdowns when charging, you probably want to get a different kernel. If you insist upon using that one anyway, try charging via USB instead of the wall outlet, it seemed to happen less frequently on older kernels, and I haven't had a charge death in weeks now, so, I'm good at least.
- See if your phone is one of the ones being recalled. If your phone is under recall and these don't work for you, I'm not sure what else I can do.
- These fixes work for me and a lot other people who had the same problem with other oc/uv kernels. Like I said, we're running these out of spec, so a few unlucky souls might not have phones that can handle this. Or maybe some of these kernels have been sprinkled with pixie dust and others haven't. If you find a different kernel that works for you by all means use it. It's all about choice people.
Thanks. Going to try it now.
I flashed 'em at 94%, so we'll see.
But FWIW- I think I've had MAYBE 2 charge deaths when I was on perception. But I was using Setiron's kernels, so I dunno...
I'll report back in a bit.. gonna let it over-charge for a bit and see what happens.
Darky 7.0.1 with your kernel and 100% battery power for 2.5 hours plugged in to the wall and no power off yet. Hopefully this is the fix, I am tired of leaving my computer on all night to charge on usb
thank you so much for this...been looking for something exactly like this, and seems sleep death is gone
darky 7.0.1 here also.
I had it charge around an hr and a half past 100% and no death!
So we'll see how it does overnight
I'll try it out and let you know how it goes, i charge by ac overnight so I should have the results of it to you by morning I'm using it with Assonance 5.2 by the way.
Well no charge death for me last night...
Sent from my GT-I9000 using XDA App
Absolutely no problem, left on ac all night with an undervolt and everything. Great job with this, it made oc/uv usable for me.
Doc's 6.1.3 + your kernel = 100% joy
I found your thread last night after a long and happy Christmas day with the family. Followed your instructions to the letter. Charged overnight from 45% and woke up to find the phone operating fine. This might be the answer to all our prayers!! Thank you so much!
Runs great with eugenes ginger clone. Slightly better benchmarks than other rom/kernel combos. I peak out at 1.3ghz so 1.2 seems like a good medium. One request though is to look into changing the divider for the gpu. I know we don't need it but its good for bragging. Unhelpful had this and I could set the gpu down to 166.750 For lower clocks to save battery and up to 222.334 (stable) for benchmarks. I never tried other clocks so I don't know if it would work on other settings. It depends on how his code works. but it seems by my math the gpu is divided off a 2000 or 2001mhz frequency. There is a margin of error I guess. and stock is divided by 10. In unhelpfuls code it is divided by 9 (222.334) default but could be set to 10 or 12. If we bump that up to 15 or 20 we might reduce battery consumtion with a gpu clock at 133 or even 100mhz. Id also like to try the divider at 8 for 250mhz. Im curious as to how that would benchmark if its stable.

Ive been charging since 2pm yesterday and its still on. I think you got the fix
No problems here charging overnight. For those who care about quadrant scores, mine was about 250 points higher than the other 1.2ghz kernel I was using.
I get better quadrant scores too vs.my setiron 1.47 1200 kernel. I don't know if it's due to this kernel, but for some reason I'm getting much better battery life since flashing it.

Same here, battery life seems better..I've noticed it not draining so quickly, im at 85% when usually id be at 50-60%
Sent from my Captivate
I've found Darky's 7.01 works best on my phone, could it be true this makes it run faster? Do I need to have full charge or can i flash this at any battery level?
I didn't look at the actual quadrant score. But my fps is on average about 2-3 greater. Similar to running at 1300 on other kernels. Battery life is much improved over the kernel in eugenes ginger clone rom.

I just flashed it over SetiroN 1.5.6 and can see a speed difference already. 1200 O/C is perfect, I really like the kernel. Working great on Darkys 7.0.1
I too just installed over Darky's 7.0.1, bit more speed is noticable but i mainly did it for the possibility of better battery because right now thats all i am after.
i just installed but i want some more about voltage control
how can i modified that option?
thx a lot!
On CM7 I dont have ondemand governor with the tiamat or savage. Only with stock CM7 kernel. What should I use instead?
Also does it take a while to notice improve me with these kernels?
Also those with awesome battery life on stock battery are you leaving wifi on? I get about half those times but I leave 3g on all the time.
I wish I could get through an 8 hour work day with 5hrs of screen on time on my battery.
Usually on my yoobao 3000mah I get 4.5hrs on screen time with no charging throughout the day lasts about 17hrs that way.
If I switch back to my stock battery I wouldnt be getting that would I?
CM7.1 nightly
yoobao 3000mah battery
tiamat 407 kernel. Everything under volted by 50mV but I do not think it is sticking.

i prefer the SavagedZen 2.2.1 kernel with savagedzen. but would suggest trying the smartass and interactiveX governors to see which one you and your phone prefer. some folks like the 3.06 version of Tiamat, you may want to ask folks in the tiamat thread about the diff between 4.07 and 3.06 (not positive on the version numbers).
i'd suggest running each for a couple days to see how it feels.
i use Tasker to activate my wifi when i arrive at work and at home...the rest of the time my wifi is off unless i turn it on.
the "5hrs of screen on time" may be an issue, the screen draws a lot of juice. perhaps if you verify your undervolting is sticking, used no widgets, do not use live wallpapers, set everything to sync once or twice a day you'd get further...but thats kinda no fun and i still don't think you'd get 5hrs.
i've had a light day on my phone...1.5hrs of screen on and i'm at 16hrs w/ 44% left. standard battery.
How can I verify the UV settings?
smartass is laggy
You guys should d/l System tuner. You can change your Governor with that app
Some guys swear by the SavagedZen kernel but it's reached the end of it's development life, the SavagedZen team is no longer supporting or updating the kernel and it hasn't been updated in almost 3 months. My personal experience with the kernel notwithstanding, I think that's reason enough to stick with Tiamat.
Turn brightness to 30 or 40%. Get a mugen 4500 mAh. Problem solved...your welcome.
Oh and there is ondemand in sz221. I am currently using tiamat 407 SBC conservative governor and my settings. No undervolt and working very nicely
I own a stock, gailio 2000mah, and siedio 3500. My 3500 never has a problem making a heavy day of use. I'm guessing that 4500 def wouldnt

you can use vipermod to set and verify your uv settings. there are other apps as well. but i find the script works well.
in CM7 you can set your governor and clock speed via:
menu -> settings -> Cyanogen Settings -> Performance -> CPU Settings
no 3rd party app is required. (unless you wish to use "profiles" like those available with SetCPU)
you may find interactiveX to be more responsive.
yes, SZ is not currently being developed and tiamat just released v407.
i may try the new tiamat kernel to see if it plays nice with my phone.
note: the new tiamat is based on 2.6.38.8 and SZ is based on 2.5.38.7.
thus far my EVO has shown a definite preference for SZ over Tiamat. /shrug
i always feel like i'm carrying around a pregnant EVO when i put on the 3500mh battery. LoL
My Evo also never ran tiamat well after 337 but 407 is running great
I avg five hours display on time. I have Deck's AOSP ROM and I turn off background data and sync twitter and email manually. I use Gemini App Manager to prevent apps from auto starting. I'm using a S-Z CFS kernel interactive x governor with SBC. I rely on 3g during my commute and wifi while at work and at home. I use the web, youtube and the xda app extensively. I don't think it is possible to have five hours screen on time using 3g only. Sprint's network is not that strong.

Because "supreme bat life" and overclocking in the same sentence is an oxymoron.
The best thing I did was uninstall setcpu and let the custom kernel work,

Currently running Taboonay 2.1b with rtrip's custom kernel 3.4 - it had issues with setcpu so I uninstalled it and am letting the kernel do it's thing - OC'd t 1.4 and it's smooth and fast but still has a decent battery life despite running a bunch of stuff, games, music, email and navigation - wifi on always...
Standby is about 3.5 days / on constantly about 7.5 hour life, so..yeah...Me likey..
YMMV

LOL, I was wondering the same thing about "boast supreme bat life and performance". This reminded me of my days of tuning cars and we we used to say "Fast, cheap, and reliable. You can have 2 of the 3."
OP, all machines won't react exactly the same way and people use their tablets for difference purposes, so having others post exactly what they have setup probably isn't the best way to go. First, you need to find a kernel that works and is stable for everything you need. Kernels are changing all the time, sometimes they move two steps forward and 1 step back before they are stable again and support everything a user needs (docking, NTFS mount, cifs, 3G etc.). After you find a kernel that is stable and suits your needs using the defaults, then you can take it a step further if you wish.
If you want a performance minded setup, setup a profile (in setcpu or one of the others) using the desired clock speed. Try 1.4 or 1.5 Ghz to start as that seems to work for most. Use the governor recommended by the kernel developer for best results. The more you over-clock, the more battery you will consume.
If things are stable with the default voltages, then experiment with under-volting to get the best battery life you can for your performance profile. Start with the recommended voltages with your kernel and adjust down -10uV at your max CPU frequency to find out how much voltage you can reduce and still have a stable system. Make sure you run through all the things you typically do and give it a good workout before moving down to another voltage. Using benchmarks can be helpful for finding stability, but may not match how you use the tablet in the real world.
If you want the best battery life, then experiment with under-clocking to 912MHz and then try under-volting that clock speed to find your stable point. You could then setup a setup "battery mizer" profile for that.
If this sounds too difficult and time consuming for you, then do as the others have stated and just install a custom kernel that does what you need and let it work for you. It should give you a good "in-between" setup. For me, I am addicted to 1.5GHz as the increased smoothness from stock is very noticeable for me. I can recharge every night after 6 hrs or so, so this works great for me. If I go on the road and need to take it easy on the battery, I use another profile to get better battery life for the time being.
Hope this helps you out.

Hah! Well thanks but I'm pretty sure I didn't say "overclocking" but gotcha thanks for the feedback and answers. I was merely looking for setups compared to what I'm running now. TIA
Please share
1. your favorite governor (do you use any different governor on different profiles?)
2. your voltage parameters
3. Your benchmark using quadrant
Thanks
No one wants to play?
Maybe like me, they have no idea what you are talking about
What is a governor?
What voltage do you mean?
My quadrant score is 3900 ish
Thanks for the reply, I don't think I'm good enough to explain but, in a nutshell,
A governor is a a piece of code in the kernel that decides on the cpu speed. each kernel has multiple governors
voltage is where you can decide what voltage is delivered to your cpu at certain frequency. undervoltage will usually help you save battery. we have to pay attention not to go too low or it phone will freeze
download setcpu it will all become clearer
I will give this another bump before letting it die
Even I would be intrested in sharing this
currently I am using CF root with ondemand and its working all good
FM kernel with interactive. I find my phone snappier with this governor. I liked it the most with smartassv2 on Abysssomething (don't remember now) kernel, but too many teething problems with this one, had to revert to FM. I'll give it another shot soon though.

Have you tried InteractiveX? Or, better yet, know the differences between the two? I am currently using smartassv2, FM kernel and have no complaints but would be interested if there was something a bit snappier when opening an app (I still get a bit of lag if I quickly select an app after unlocking the phone).
Yes, I've tried InteractiveX and OndemandX - they're both absolute rubbish (at least from my point of view). Both responsiveness and benchmark results were dismal (2800-3300 quadrant advanced). These are governors for anally retentive battery life lovers. Nothing wrong with that itself but beats the purpose when buying state of the art top shelf performance smartphone IMO.
Good to know. I appreciate the advice. Does that mean you also tried smartassv2 with the FM kernel? Any discernible difference between that and interactive, if you have? And sorry for all the questions but it saves me the trouble of trying them!
I just flashed the 1.3 FM a moment ago. Now running 100-1704 smartassv2, haven't played with voltages yet. Responsiveness in terms of screen scolling, lags & stutters seems better than 200-1400 interactive. Performance in Quadrant Advanced and Nenamark2 seems a tiny bit worse (but I don't really care about that, I use benchmarks only to roughly estimate, smoothness is what I'm after). I can't give you direct sources because I don't remember, but having spent several hours digging last weekend I concluded that for people who put performance slighly over battery life governors to be considered are interactive, smartass(v2), savagedzed and performance. Funny enough - I'm getting consistently worse benchmarks on performance governor on all kernels. I wonder why?
Thanks again. I will play around with some of the governors and settings to find the right fit. I think I will try savagedzen next but I am pretty happy with smartassv2 and may just stick with it.

i share with you my SetCPU config, voltage ...
it's very stable for me. It's not performance oriented but battery friendly.
what you think ?
EDIT : I use AbyssNote Kernel 1.2
I'm getting nice results here on FM Kernel 1.3. 1704mHz (1375mV) - 100mHz (775mV), lulzactive governor. 5000-5872 in Quadrant advanced, 32-35 in Nenamark2. Battery life good with low to med usage, poor when playing games, running satnav etc. - hardly a surprise We'll see about stability but so far so good.
This thread is finally picking off ! thank you all
I am currently on FM 1.3 and preferring lulzactive
I don't use any over clocking I guess I don't dare. is it safe?
I think i'm pretty aggressive with under voltage i'm running 1175mv at 1400mhz and 775mv at 200mhz. For some reason my phone freezes any time I use the 100mhz no matter the voltage .
Can you share the whole voltage for a comparison ?
with all this I can hardly get a full day of use with my battery but I guess I'm a pretty heavy on usage. no gaming or anything extensive but wifi-browsing-emails-3g-bluetooth all day

hi
i have a htc evo 4g running android 2.3.5 and kernel 2.6.35.10-g4b48446 [email protected] #1 and i have a few questions on setcpu. its a stock rom and it is rooted.
I shut off my profiles and disabled the perflock - it said success. So i ran the long bench test and only got 2078 ms, not 5000. so i dont know if its really working. I reengaged the profiles and i think it works with the screen off. the rest of the time i am not so sure. in fact it seems to still drain fairly rapidly unless i turn on some battery saver or something. I have the following settings on my profile all are set to ondemand except charging which is set to performance. the only other setting i can choose is user
in call 998 max and 245 min priority 91
screen off 384 max and 245 min priority 88
charging any 998 max and 245 min priority 85
battery <25% 460 max 245 min priority 81
bbattery <50% 883 max 245 min priority 65
Temp> 42 C 614 max 245 min priority 50
what am i doing wrong? I have it enabled and i have notifications off
i have system panel to try and monitor but its not recording and it also drains the battery like crazy so i think thats set wrong as well but i dont know why.
i also tried juice defender but it doesnt work right because it says the AOSP file isnt found in the system/app folder. I looked there and also in teh data/app folder and its not there. So i dont know what to do about that.
thanks
stock sense is just not all that efficient really. (well thats my opinion) profiles seem to look ok but also finding a different kernel with different governors (smartass v2 is rather efficient and changing around the frequencies as needed)
auto sync settings as well? turning some stuff of that you dont use or look at and so on can help too
and calibrating battery a bit can help aka a full discharge a full charge and full discharge will sure help (also what i have found personally)
kernels
thanks for the reply. You mentioned different kernels. I understand about rooting my phone but not so much about how to load a different kernel or different rom. Where do i go to learn about that?

look around in the development section as there are some great kernels available right now...Ca1ne just released a new version of the underworld SBC v6 that i personally like with great battery life ...Mason kernels are also great with great battery...just make sure u read the threads completely to make sure u are using the right kernel for the rom u are using...ie there are kernels for ics...sense....and so on......also the kernels load through recovery...just load kernel to sd and wipe cashe and dalvik and flash zip...hope this helps...Carp
Hi another question about kernels. I am a bit of a newbie other than rooting my phone so i want to understand what advantages/disadvantages different kernels have. You mentioned smartassv2. i have seen others like
chopsuey kernal
freedom kernel
golden monkey kernel
savaged-zen kernel
tiamat kernel
all of these i think support sense roms.
as i understand it , you have to go into the recovery screen and load hte zip file off the sd card and reboot with the new kernel. What are the risks/rewards of doing so? I guess i am trying to understand which one would suit me best.
i have the current sprint lovers rom i guess since it is factory stock so should i also be considering changing the rom? Maybe i am getting ahead of myself here.
thank you again.
which rom are u wanting to run....this will help us steer u in the right direction
im sorry your entire post didnt load on my end i see ur running sprint stock....that is a fine rom but i have not ran it myself....

i personally have switched to sbc kernels when they came out with a sense version...i am addicted to sense 3.5...just my personal likings...sbc is superior battery charging whichcarp will give u better full charge on your battery so when the light turns green and u unplug it it wont drop down to like 90% battery in just a few mins....i can squeeze another couple hours out of my battery with sbc and even more depending on light usage....but u will stil need to play around with different cpu speeds like 786..921 and so on to see what your individual evo can stand....what works for 1 may or will not work for another....lags and bootloops etc...
You don't need to change Roms, you can if you want, but changing kernels will unleash new features. Some features are:
Full hdmi mirroring
The ability to over/under clock CPU
2 way call recording
Improve battery charging
Enable swap space
Improved performance of phone
Some kernels allow under volting CPU to further save battery (this can cause some stability issues so start slow with undervolting)
You may want to take a look at Lionfish kernel also, just note first boot may take a while.
Also ditch the profiles in set CPU, I tried profiles and it never seemed to work right. A good governor will handle all your profile settings.
I like smartass, and intellidemand the most on my set up.
As an idea ok the battery life I am getting, I streamed Pandora over 3g for about 8 hours not much other phone use, screen off most of the time, and my phone was at like 20 %. I thought that was pretty good.

thanks detcup4evr for helping out explaining that better...i blew out my back and between no sleep and pain meds the brain just dont want to fire...thanks for stepping in bro....carp
smartassV2 vs InteractiveX ... which one giver better performance AND battery life??? currently I am running LIONFISH 1.8 with interactive X
Using profiles in setcpu actually uses more battery life. Because it has to be running all the time and monitoring phone state to know when to change to a different profile.
interactiveX vs smartassv2 all depends on how you use the phone and really which kernel it is. I've noticed little things like on mason's I got better battery with smartassv2 but on other kernels I get better battery with interactiveX. As far as performance, you won't realize a difference.
ok so it sounds like i should try the sbc sense 3.5 kernel with the smartassv2 governor. Did i get that right? i will look around to see where i can download that.
Were you refering to this kernel?
Underworld Sense Kernel v0.6
yes this is the kernel i run with ODJDub HD Bliss!! Sense 3.5...if u choose to run this rom it will give u alot of different options of kernels and apps and other things from the installer....if i can help u more just feel glad to hit me up....carp
Ok so with lionfish 1.8 kernel and interactivex, I should not use a profile? What does CPU go to on screen off? also where does it mention profiles use battery? I'd like to read more into this..
Thanks

Sense rom with Underworld v 0.6
At Carp -
thank you for the advice. I was thinking maybe i would use my ROM still (its a sense i believe) and load the underworld v0.6 kernel with sbc and see how that goes. I havent done very much research on ROMs so i dont know that i want to get that deep into this just yet. It seems like underworld has alot of nice features. One thing that i am wonderig though is with the new kernel would have any further ability to unload some of the sprint bloatware or do i need a new rom to do that or is there another way to do it? Things like qik video , gmail, accuweather blockbuster etc all load themselves periodically. I kill them but then they come back like weeds. Even programs i do like , like pandora, wheres my droid etc come back also. But i dont want them to.
no u will be fine getting rid of apps and bloatware u dont wont...u wont need a special rom....i use a free app in the market called root uninstaller to get rid of useless bloatware,apps etc...then u can go in and manually uninstall what u don't want...be careful not to uninstall anything which the phone needs to boot and operate such as android system...you will see the things u are looking for when u load the app...hope this helps...carp
I actually did something unusual.
I have universal aggressive lionfish SBC 1.8, swagged out stock N, and smartassv2
I set the ideal, sleep, and wake freq for smartass v2 to 128, while setting the up rate to 245. I used set cpu to lower the min freq for my device to 128. I set max load to 100, and min load to 85, and down time to 0. I then set a profile for "ondemand" during screen off, of 128-384.
I actually have pretty awesome battery life (I'm an uber heavy user).
Sometimes it reads that I spend over 70% of my time at 128mhz.
I feel no lag. It clocks to 998mhz maybe 15% of the time, mainly when loading web pages.
flashed underworld v 0.6
Hi Carp,
well, i flashed the underworld v 0.6. So i see in set cpu that i can underclock to 128 and overclock to 1228. however, i slid the slider over to 1228 by accident and it froze the phone even though it says its still at 998 mhz. then it rebooted by itself. so i guess that wasnt a good idea. Anyway, theres a ton of governor choices now in the profiles section. i am not familiar with alot of them but i was wondering which of those would provide the most benefit. they are as follows -
ondemandx
interactive x
intellidemand
smartass
interactive
conservative
smartass 2v2
performance
along with ondemand and user space from before.
thanks
Good to hear....u will need to try different settings as each evo will be a little different...ie.. some can take alot of overclock and as u said when u went to high it locked up......my evo likes min 245 and i dont go very little over 998...mine does not like high overclock....i run between 768 and 998 or until i can see a lag or slow down in performance..depends on which rom i am running...i like ondemand x and smartass 2 on my evo but there is a good read in papa smurph's smurphed out v6.6 thread in development on governors and such...go to post #2....i wish there was a perfect setting i could give u but u will have to see what your evo can take...part of the fun of android.....carp
Governors
Thanks carp. I guess experimentation is the only way to know. i charged my phone last night ad i noticed that it does take alot longer to go from 100% charge to 90% but i also noticed that the phone temp was at like 110 deg F and a voltage around 4.263 or so. i have read some thread where they claim its bad for the Lithium ion batt to be over 4.2 V but as soon as i unplug it it drops to 4.1 something usually. I am using battery indicator app to measure it. i am using the underworld w/sbc kernal currently but the voltage being higher has me a bit concerned that i am damaging the battery kind of like pumping water into a jar with the the lid on tight til it bursts. Or in the batteries case - too hot i guess or until it plates.
