[Q] KT747 Kernel Help - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Alright so I am using KT747 Kernel with Ktoonservative/Noop, 1512-384mhz, screen off 486mhz. I was given an option to Lock frequencies which disallows apps to modify the speed. However I noticed after I checked this some of my apps started crashing. I want good battery life (forget to mention I undervolted) and want to know if locking frequencies is what is making the apps crash. Any help would be great, and feel free to post some good settings for the kernel for optimal battery life with pretty decent clock speeds as well. Thanks again.

If your apps crash it is more likely to be caused by your undervolting.
And for the setting go there:

Yeah I read your post earlier in that thread and was using your settings. I've come across a newer problem, my phone randomly reboots. I don't know what was causing this so I restored default settings.

When you change kernel or kernel setting it is usual that your phone may need a few reboots before stabilizing
Sent from my SGH-I747 using xda app-developers app

Unlock the frequencies and run the app that causes the reboot. If it doesn't reboot that was the problem. More likely its too much under volt. The table in the link is some pretty severe undervolting. 740 is a long way down from the stock 925. That's great if your phone can handle it, but can cause problems if it can't. Piece of advice, never use any set on boot settings if your not sure it will. You may find yourself in a bootloop and have to reflash the kernel to get out of it.

I doubt locking the frequencies has anything to do with your reboot problems, this simply dissallows any apps that are capable to override the voltage settings for any particular frequency step. In fact, unchecking this may actually give you a false positive of it 'fixing' the problem when it is actually just using the default (or higher) voltages, burning up more battery in the process. As mentioned by jethro and liltitiz its more likely your UV settings, keep playing with them until you find the happy spot (works on other things too....:silly.

Or just move the ktweaker apk from the /system/app directory from a recovery based file manager. This will keep it from launching on startup and then can either be moved back or ran to reinstall. This way you dont have to cleark the dalvik cache, which should be done any time a kernel is installed, eliminating the extra long boot time when this is done. Either the built in TWRP explorer or the Aroma File Manager which can be 'flashed' in recovery. It doesn't actually flash anything, just unpacks, runs, and then is dumped from memory on reboot...very handy if you dont have TWRP or can't get into android.

[Q] setcpu on baked snack question.

So I'm running baked snack here and really beginning to enjoy it and this whole root thing. I've installed setcpu but every time I back out of the interface it goes down to 691 no matter how high I set it or on any profile. Does this not work with baked snack? Am I overlooking something or did I set it up wrong(I used auto detect when I started)?
Did you flash a different kernal?
Sent from my PC36100 using XDA App
Nope I flashed kernel 3 I think or what ever came included in the baked snack.
should I DL that kernel by itself and then flash over the Baked snack with it? and whats the difference between flash over and flash ontop of?
Damn the stupidity of it all... lol. I set my profile to 691 if my battery was under 40% which it was... but now when I plug my phone in the cpu goes up to 1ghz which I have it set to but my battery keeps going down. Now this is a problem here if I'm not able to charge my phone while the setcpu is running it will get really annoying really fast. Considering the app manager that I have refuses to close it so I have to manually go to settings > applications > manage applications then go to setcup and force close it to charge my phone it seems. Do you guys think its a problem with my cpu being set to high while charging should I drop it down a whole bunch for the charge process too? That doesn't seem like a very needed thing to do I would assume it would be able to charge just fine without that. Looks like I got a lot to learn about this whole rooted phone thing.
Check your profiles in setcpu and make sure you don't have one that's at that speed with the highest priority. If that all checks out fine I would flash kernal 2 (my favorite) don't wipe just flash. And as for your question over or on top they mean the same thing and that's flashing the kernal without wiping.

Also do you have overclock widget running as well? If so they might be fighting eachother
Sent from my PC36100 using XDA App
not even quite sure where the overclock widget is. I looked to see if setcpu had a widget and it wasn't in the widget menu. Where as most of my other installed apps have a widget assossiated with them. I'll look into kernel #2 right now, I still have some more flashing to do.

Overclock widget is just another widget you can download that runs seperatly from SetCPU. You should have a SetCPU widget though. I would try reinstalling SetCPU also

[Q] Best Setting on tuner pro for Dewizzed 2.0

I am trying to figure out the best setting for the rom. I am only getting like 6 to 8 hours on my phone. When I've seen others get close to 24 with light to moderate use. Like I stated in the Title The rom is Dewizzed 2.0, and I know the some people have the same rom while using tuner pro. I would ask the dev in the devolpment section, but I don't have permissions to do so. Also Hello everyone in xda. I am a long time visitor since the G1 days. I made this account a long time ago, but recently got tired of touchwiz, and decided to give it the boot lol.
from what I have heard... for dewizzed... if you use Faux, just flash gideon's script you might want to bump the clock just a bit over 1ghz to make it smoother... i believe synergy kernel works really well with dewizzed from the getgo (haven't tried it i get good results from faux).... if using gideon's script.. don't use a cpu tuner, you want to manually adjust the values in the script.

See this is where I seen people on here talk about scripts. While yes I hear great things about it. I'm pretty stupid in to what it it, does, or how to apply lol. As to say why My idiot self uses setcpu, but apparently setcpu gets stuck on conservative which was creating a noticeable lag. Which in turn lead me to tuner pro. Which in turn leads me to look for the appropriate settings I want. Just don't know how to achieve that. Things sure have changed since the G1. -sigh- Sorry if I'm more of a pain in the bottom. :\

scripts are basically tweaks to your phone. They're PreProgrammed tweaks that runs when your phone is booted.
Basically gideon's script controls your phone's clockspeed and voltages without the need of a 3rd party app. Therefore when running tuner pro it overrides the script... go to faux's kernel thread... it's in the 3rd post. You flash the script through cwm.. check out synergy's thread for its own configuration.. i haven't really checked it out yet (i should)... heard great things about that kernel
Here is a link to Gideon's scripts. Before you flash them uninstall system tuner, and wipe cache and dalvik. I suggest putting the revert script on your sd card also. In case your phone doesnt like being under volted. You can boot into recovery and flash the revert script.

I am running Dewizzed 2.0 with Synergy kernel and using System Tuner Pro, 1.62max 384min, 384max and 192min with screen off and am not UV because Synergy is already UV. Getting well over 21 hours of use, light to moderate usage,
Sounds like you have a app that is using a lot of battery.

Setcpu causing problems with ICS?

Is anyone having problems with setcpu on any of the ICS leaks or cm9? My phone just freezes up upon boot and has to essentially be redone for the phone to boot. The second setcpu runs, my phone locks up. I have a screen off profile with max at 800mhz. I also tried it without the screen off profile. I have decided to hold off with the app until it is more stable.

Same problem, I have official ICS Rom for Galaxy S2 and several programs are freezing my phone when trying to overclock (or lowerclock). The only program working good for me is "No Frills"
Same here. I had to get rid of set cpu bcuz it would freeze the phone. Now i just have tegrak and i wish it had profiles...

I have the same problem, tried setcpu on miui ics, cm9, custom ics roms, it freezes my phone on all ics based roms?
It gives problems on GB as well, and freezes my phone. I suspect its the new version.
My experience was the opposite. I kept freezing with tegrak (free).
I bought ultimate, and havent froze yet. Got profiles so its easy to save battery when you need. No more editing init.d scripts...

Antutu CPU Master works well and has profiles.
i had this same issue, the second i downloaded setcpu my phone started freezing for long periods of time, does anybody know if this is because it is conflicting with the presets built into the ROM?
SetCPU is for custom kernels, while tegrak is for stock. Im not sure of any custom ICS kernels besides the repacks. My phone was unplugged for 16 hours using tegrak and FC24. And he only problems i had were on the free versi0n.
My solution would be to check out tegrak if SetCPU is giving you issues.
Some roms come with undervolt scripts built in, SeCPU could be conflicting. Not sure though.
If you check Calk's ics ROM thread in Android Development, his latest release notes say something about having an issue with Ics freezing at 800, so it could have something to do with that. Don't know more myself, but hopefully that points you in the right direction!
Sent from my SPH-D710 using XDA
Not to be a smart***. But everyone does realize that ICS is designed to handle all this for you right? Thats why I never included these cpu or voltage tweaks in my ICS roms. No reboots or freezes... Some may not get issues... But most will if you use them

[Q] Horrible battery life

ive tryed everything. android system is always higher than screen no matter what i flash, ics or jb. this is just getting annoying how it drops 1% every 2 minutes, when using it with data. i really like this phone but this is just killing it for me. i attached some pics of the battery and the kernel wakes. any help would be great.
thanks
WOW, that is crazy. I can only suggest Wicked V7 updated to the latest official ICS. Do a full wipe of everything and install. I have been running for 2 days and have great battery.
Good luck bro
idk what it can be I've been switching roms and ics or not android system is always higher than screen . Could it be an app or a file that's causing this?

Nope cpu spy shows how much time the phone is in different mhz.. like if you turn off your screen it will go into deepsleep and when you open the app it indicates how much time the phone has spent into deep sleep...
And OP maybe its a bad battery if you have tried ics roms and jb ?

Well, what do you guys think of this? I'm new to the S3 not familiar with the ROMS. What's the best ROM out there for us with good battery life and performance?
I really like the CodenameAndroid and ParanoidAndroid roms in combination with Ktoonz kernel, I get around 2 days of battery with moderate usage and over 6 hours screen time, which IMO is great for the US S3

holy sh*t the android system is raping your battery, well I love wicked roms(ICS) awesome battery and super smooth. You can also check out FrostyICS and FrostyJB those are also really good ROM's. I personally like ICS ROM's as they are more stable and don't have minor issues that some the JB ROM's have.
Check out post #3112 and #3113 in the WickedV7 thread and check out the battery life pic people posted on that ROM.
GO to the Play store and download no-frills CPU control or set cpu and check and see what you Min and max is for your CPU.
I have an extended battery and after 4 hours i was at 65 or 70% which is way off!!! I check this and it showed that my min and max was at 1024 once I changed the min to 384 everything got better

When it comes to battery life, there are many thing that you can do to improve it.
First off, turn autobrightness off, and try and keep the brightness slider as low as comfortably possible.
Dark, if not completely black background are not only sick looking, but they help with your battery life.
Less widgets, especially ones that require frequent updates...like weather widgets, and facebook widgets will wake
your system up to update. I suggest removing most, if not all of your widgets from your home screens.
Download an app like setcpu, nstools, or voltage control to set your min and max frequencies. In setcpu, make some profiles for screen off to
make sure your system isn't throttling up while your phone is not in use.
Change your governor and i/o schedulers. With a high end device like this, you can comfortably sit on conservative governor without experiencing bad lag...i/o schedulars wont effect battery life too too much but simple ones are best (like sio).
Run v6 super charger, kickass kernalizer, and 3 script to improve the way your device runs, and battery life. Stick to wifi when possible. Having low signal will cause your phone to constantly look for a better signal which will prevent it from deep sleeping.
Use titanium backup to freeze unnecessary processes, such as DRM protected content.

Good luck!

This was mentioned in another thread. DL this app: https://play.google.com/store/apps/details?id=com.eugene373.cpu.sleep
It shuts down one of your cores when the phone isn't in use.
Also DL CPUspy. This will show you exactly how often your phone is using certain frequencies, and whether or not it's going into deep sleep.
It looks from your screenshot however that your standby battery is not the problem, it seems to shoot down when in use (at least I'm assuming that was from when you were using the device).
Click on "System" and take a screenshot so we can see what's going on
Sent from my SGH-T999 using xda app-developers app
Error is the first thing listed. Have you tested the battery by doing a full reset and flash, then not installing any apps? If this is happening across roms and builds its most likely one of your apps not playing well with the system.
Before your next flash, go into dev options and turn on Show CPU Usage. Then let us know what processes seem to stay at the top all the time.
Also get cpu spy from the market and after letting it collect its data for a while (especially when not using the phone) check it to make sure its going into deep sleep.
After those two, do your clean flash and run without installing any apps for a while. Then when you do install them, do not restore from a backup. Download them fresh from the market. Also do not restore any backed up data, at least at first.
When you do flash your system, download the full firmware to your computer (use root66 if you want to keep root). From recovery choose format data, this will wipe your internal sdcard, btw.
Now boot into download mode and using Odin, flash the firmware you just downloaded.
Once done charge back to 100% and see how it goes.
You can get the firmware from my stickied thread in development.

As long as you follow instructions, and make sure you have the correct fw for your model, Odin is actually quite easy to use.
Restoring apps and especially data can cause all kinds of issues when jumping between different builds and especially android versions. The updated apos and system often have different database structures, different data files, and even different storage locations sometimes.
I'm betting this is where the problem will be.
I understand not wanting to go through all that I mentioned, but if you want to know where the problem originates, you have to start removing variables to narrow it down.
If you don't care what's causing it, jump to the flash. Nandroid backup, wipe everything, odin flash, test. If all is well, restore the data part of nandroid. If problems start again then you know its either your apps or data causing the problem.
Odin instructions are in TheExels thread stickied in this section.

[Q] Stock CPU & Voltage settings?

I think I messed something up. Can anyone help out? I used pimp my rom and thought I'd saved a rescue file, but didnt.
My phone drops from 100% to 0 in a mere 1 hour, using fancy kernel. and a rom.
It runs fine after wiping and loading stock google rom, but once I re-load the rom/kernel it goes right back to ruining batteries in an hour.
If anyone could post a screen shot of their stock cpu speeds and also stock voltages? Thank you very much!
Clear data for Pimp my ROM app? Stock voltages are dynamically controlled through SR (smart reflex); and why do you need to know stock CPU speeds if you're running a custom kernel?
I don't get it.

Thanks for the reply. I think it was a bent/dirty terminal in the charging port, not originally what I thought.

Honestly, I can't relate the issue you were describing with the solution you just posted.
a manta wrote this.
I was confusing a couple issues. While I was on a custom ROM, my battery would display ghost charging lights and major amount of battery drain. I thought it might have had something to do with settings I had changed in the pimpmyrom app.
Not knowing the kernel resets things, I simply wanted to check my settings.
The true cause was a bent charging pin that was shorting. Straightening the pin and cleaning out the USB port has resolved my issue.
