Which kernel should I have if I just want OC?

My phone is rooted and has s-off but I have a few issues. One is almost half the time when I hit the power button the screen doesn't turn on instantly but the soft buttons light up. It usually takes me hitting it 2-3 times swiftly to get my screen on. Another issue is sometimes wifi calling gets screwed up so it doesn't work and it drains my battery as a background task stuck on restarting. I really only want my phone overclocked so just have baconbits kernel. is there a newer version I should put on that fixes these issues?

Baconbits, to my knowledge, is the only OCd kernel available for the stock ROM. Your screen issue might actually be caused by underclocking though, do you have a screen off profile or a minimum set?

I just have it set to 368-1497. Should I up the minimum?

Give the overclock widget a try. Its available free on the market. In the advanced setting, set your screen off profile to 245 min and 806 max. Scroll down and hit "save" before you exit settings. That will keep your phone running at stock speeds while the screen is off and should stop the wake issue you're having. When you're using the phone you'll be at the higher speeds.

I already had the widget. Did what you said but it still occurs.

245 is *way* too low, especially if you have things running in the background ... just start raising the lower end up until it stops happening.

Setting it to stay at 800 while the screen is off seemed to fix it. Any ideas about wifi calling bugging out? It usually doesn't happen very often, I think when my phone has been on for a while without a restart.

overclock widget doesn't overclock anything.... it controls the speeds AFTER you've installed an overclock kernel. I highly suggest using flippys turbocharged 1.8ghz kernel. Just because it is capable of 1.8ghz doesn't mean that you need to run it at 1.8ghz. you can just do something like 1.1 or something in between. Give it a look.

Nobody said the OC widget overclocked anything. Did you read the OP's first post? It was suggested so as to enable a screen off profile because the OP is having a wake issue while using baconbits.

set the off screen profile to the lowest speed 200/200mhz and 100% priority and he wont have anymore wake issues, don't know what I was reading hahaha

The screen on issue doesn't happen anymore but I'm not satisfied with my battery life. In the past something was causing my battery to drain insanely fast so I un installed a bunch of unused apps and started checking background tasks but when browsing the internet for 20 minutes on my way home I use 30% of the battery, bluetooth on.

Anyone know if it is possible to run Pershoot's kernel on the stock rom that comes with the device? Any side effects?

I don't know enough to say 100% one way or the other, but I read in a post I can't find right now that only BaconBits is made to work with the stock rom.
FWIW, I tried to flash the 1.8 GHz kernal on my stock G2 this morning, and got stuck in a boot loop.

On AndroidCentral people are saying they have improved battery life with CM7 nightlies. I'd like to try running a ROM finally. Do I need to get rid of my Baconbits kernel before proceeding? I already backed up everything with Titanium.

NO. The first thing you need to do is flash clockworkmod 3.0.0.5, which is totally different than ROM Manager. As of right now the latest clockworkmod available through ROM Manager is 2.5.1.3. If you haven't flashed that yet (2.5.1.3) do that first through ROM Manager. The best way to flash 3.0.0.5 is to find the .img file, place it on your sd card and run the commands from terminal emulator. After that just wipe data/factory reset, wipe davlik cache and flash the latest nightly .zip, reboot, then the latest gapps .zip. Go to the development forum and the first post in the nightly vendor vision thread has all the links you'll need.

[Q] CM7 LauncherPro hang on boot

Just wondering if anyone else is having the same problem with CM7 and LauncherPro.
After rebooting, LauncherPro will hang for about 5-10 minutes before Android will force close it, or if I long-press the back key to manually force close it. It's only slightly annoying, since it functions properly afterwards, it would just be nice if there is a workaround or fix available so that I wouldn't have to do that after my daily reboot.

Sometimes it just happens, you may want to check you minimum frequency of your governor.

Min: 245
Max: 998
Governor: Conservative

You can try smartass...and what kernel are you using?

Yeah I am having the same problem. LP always forcecloses when I restart on RC4. Its not to annoying though.
Sent from my PC36100 using XDA App

Been happening to me since at least RC2, using stock kernel, minimum frequency of 384.
I'm pinging the devs to see if they know anything about it...

Latest SavagedZen.
Conservative gives me the best battery life without sacrificing performance. From what I've read about smartass, I wouldn't like it.

Try setting memory usage to "high" in LP settings.
Menu>Preferences>Advanced Settings>Memory Usage Settings>Memory Usage preset>Select High.

Word from on high: We need some logcats. When I get home from work, I'm going to be flashing N35, no GApps, install LP, reboot, and then grab the log.
Hopefully that'll light some fires under people's arses. ;D

I have this issue as well.

Just chiming in that I too have this issue, also from about RC2.
Have used stock and Tiamat kernels, both exhibit the same behavior descibed in the OP.

I flashed Tiamat but the problem still exists, so I'm going to say it's either LP or CM7. Testing out the memory boost for LP now.

I have had this same problem with both my old Hero and now the Evo. LP Pro always hangs 1-2 min at bootup. Alternating between conservative, ondemand, smartass does nothing. I used CM6 on Hero, CM7 & Destroyer on the Evo.
Does not hang when I use SprintLovers.

I'll try that out. The thing is, shouldn't the phone be running at full blast on boot? What would the min freq have to do with that?

If you have the "set on boot" option checked, then its running at whatever is set.

I unchecked "set on boot" and moved the min freq up to 384, no dice still hangs.

Well you'd have to re-check it after its reset. Are you using a custom kernel?

Sleep of death

Is anybody else having issues with their ET going to sleep and you have to pull the battery to get it come back up? I thought it might have been my setcpu settings. So I cleared them and uninstalled it. I tried the midnight rom and the starburst rom. I tried the stable and exp LosKernel. None of these got rid of this issue for me. Randomly through out the day I can try to wake the phone up to use it and nothing happens. After a minute or two I have to pull the battery. I am currently testing the stock kernel.

Thats weird, the only time that happened to me was when i had setcpu, and i tried putting "screen off" value to 200/200.
You should install setcpu again, and make screen off value 500/500, and if you dont have the issue, then try making the value 200/500, if you dont have the issue at this value, then leave it as is.

I agree it is weird and I am not sure why it is happening. If it stays okay with the stock kernel then I may wipe and try the viperrom.

Yep happened twice the other day... Im on stock rom with lost kernel..roooted i put setcpu to 200/1200 after waking my screen for a minute used google came back 3 min later and phone was either off or wouldnt wake .. I had to pull battery twice.
I setcpu up to 1200/1200 never happened again.
This is a nice phone but very touchy.. Seems alot weird things goin on for some Et users.
Worst of all for this phone is Los or just weak /radio signal in general ..which is a samsung issue.

Why people still insist on screen off profiles amazes me. When you hit the power button to wake it - the phone is stuck at 200MHz, you do realize this? If snything else is going on while it's stuck at 200 or SetCPU doesn't sample the phones state fast enough, it never gets out of 200MHz and locks up. Just like any other processor does when you overload it.
All the background processes going on even when the screen is off and somebody thinks setting the CPU max to 200MHz is a good idea? That's just asking for it. Not to mention the screen off profile is known to cause this issue. Notice how Virtuous, Viper, Cyanogen, and many other developers don't use one in their native OC daemons? There's a reason why. The phone sleeps just fine without it, just let it do it's thing.

Don't use offscreen profiles (the kernel is smart enough) and avoid using task killers, as those are likely to be the second leading issue.

I am having the issue even with setcpu uninstalled. I still have not found out what is causing it.

Just wanted to throw this out there: beware mislabeling this problem. The setcpu issue causing the phone the permanently lock up and require a bat pull is one issue, yes; slow screen wake up is a different issue. Sometimes if you hit the power button, the screen will not wake up on the first try. If you wait a few seconds and push in the button again for a second or so, the screen almost always will come after. Coming from a mo-pho, I actually had the stupid no-wake problem requiring bat pulls, so I'm extremely paranoid about by e4gt doing this -- but it really has been good about eventually waking up every single time...just try my instructions and see if it works for you, too.
Again, though -- setcpu issues may be a different problem entirely.

did you reinstall a rom and try it again or did you simply just unistall setcpu and try it. I say this because I had an issue when testing setcpu and my system still kept my cpu setting even after I unistalled the app. I had to reinstall the rom after wiping to get it to run properly again.

I think I have found the issue. I did a factory reset and installed the rom but I am getting an error now that is basically saying it can't read the internal storage card. So I think there are some actual hardware issues going on that need to be looked at by sprint.

how often has the sod been happening? I think i got it yesterday, but not sure.

Do you use setcpu?

This thread seems a little slow- has there been a solution found or are we isolated cases?
I reflashed the phone back to rooted stock and then flashed Blazer 4.1.
Got 2 SODs in the past week- one just a few minutes ago.
I tried calling the phone from another line, it rings but the screen is black and thus I couldn't answer it.
Power button and vol buttons work fine.
I had to powerdown and reboot.
Getting kinda frustating.

Random Reboots. Throw some ideas at me!

Hey guys, I constantly have random hot reboots. No pattern or anything, it just happens. I have asked a few guys in Calkulin's forum... everyone offered help... but no one actually helped me fix the issue.
Basically, I am on Calk's 2.0. Only other thing I flashed was Overstew's ICS theme (I used themeporter). No, my issue isn't the theme. I have had these issues since Calk's 1.5. Theme or no theme.
Here's my routine of setting roms up:
Manually wipe everything -sd card.
Use Calk's Format All.
Flash Calk's 2.0 and Overstew's theme.
Reboot.
Install Titanium, but only restore apps (41 apps), no data.
Set LauncherPro as my default launcher.
Setup my settings.
Just using Calk's stock battery saver script. No overclocking or undervolting.
I have tried wiping and new downloads several times. I wiped my external sd card. I even removed it, for a while.
Any ideas? I had a logcat during the hot reboot too. It had some errors around GPS right before it rebooted.
Thanks
P.S. I also had the same issue on my old Evo 3d. I just thought it was my hardware...

Undervolting is what Calk himself recommends to fix hot reboots. It's in the OP on his ROM threads. Also different kernels. Tried any of that?

Actually, he recommends restoring the Stock Voltages to remove the default undervolting.
"Having random reboots or freezes?
Try flashing the Calkulin's_Undervolt_Stock_mV_Settings_for_E4GT zip attached or flash a different kernel

first thing that comes to mind is the viper los script

I don't have the Viper LOS. I have tried different kernels. Plus, isn't 2.0 using Rogue's stock anyway?
I'm not undervolted. 2.0 can't be undervolted without using tegrak :/ all great suggestions... it's driving me insane that I can't figure this out.
Sent from my SPH-D710 using XDA App

I am on Calks 1.5 rom and do not have any reboot issues. The first thing I do when I flash any new Rom is put back the stock pulled kernel and I believe this is the most stable of them all and I also have never seen an LOS on it.
Do you have any battery saving apps or task manager apps running? I know these have caused issues like this as well...

No. Nothing! I had stock pulled kernel before. Maybe I will try it again. But isn't it the same as Rogue stock + boot animation and init.d?
Sent from my SPH-D710 using XDA App

I used to have random reboots with different lockscreens from the AIO mod. Had no lockscreen and had no reboots.

Definately recommend stock kernel and restoring stock volt settings. As for Los, ek02 fixes it

Hey I remember chatting with you in the Calk rom thread. "OP"
As a update to my situation. I was also having random hot reboots on EVERY rom I was on UNTILL my latest combination of Kernal / Rom.
My current setup is Kernal: EK02 and my rom is Calk v2.0 which is built on the EK02 stock build.
I have yet to have any hot reboots. My current Up Time is 38:58 which means I have not did a battery pull or reboot in 38 hours.
I also use Titanium Backup to restore about 30 apps + data on my end, and MyBackup Pro to restore bookmarks / texts
For the first time it looks like my hot reboots are currently fixed. I dont use any undervoltages and no SetCPU no custom launcher and no custom lockscreen. Everything Stock and all 7 home screens nearly filled with icons and picture frames ect...

I was using Rogue's kernel and was going to switch to stock today, as that was the only thing I didn't do... but I was in the middle of calibrating my battery this morning and I was getting great battery life. Well, 15 hours later, not one hot reboot, light usage (lots of texts through google voice and xda, and a little browsing) with a screen on time of 1:45 and I'm at 54%. Has my issue been fixed? I have no idea. Am I happy at the moment? F*ck yeah.

After jumping to the EK02 Rom and Kernal Im also a happy camper now.
No reboots / No los / No lag / No dieing battery.
Now if only Sprint could fix there slow 3G that be great.
On the topic of battery, I never calibrated or did anything special but I noticed my phone can last 12hours + without charge if I turn off 3G when Im not using it. For example I work in a warehouse where I get good signal for calls and texts but 3G is mad slow, so I turn 3G off but am still able to recieve texts and calls and my battery life doubles in that period of time. Soon as I turn 3G back on, battery starts to die faster.

Sleep Of Death

I don't know if this possible but I really like to find out if there is something causing the SOD that we can actually do something about(as in it isn't hardware causing it). I get SOD's on some repack kernels but not on others. When I get it has quite frequently. I am not running setcpu nor do I have any other software controlling the cpu. I have however been using juice defender. I like the product. I am going to remove it and flash a repack kernel that I know gives me SOD's and see if something in the power saving on the JD might be contributing to it. I would like to hear from others that have this issue and see if you are running anything like setcpu or JD.

I've been thinking of something. I don't have sod at all. For those that do have sod how good is your phone at overclocking? Meaning can it run stable at like 1.6 or where does it freeze at?
I'm wondering if its something to do with the difference of processors.
If anyone needs any help with the epic touch hit me up on Gtalk @musclehead84

I dont really overclock anymore but when i used to, my phone froze at 1.6. This was back when i was on calk eg30 rom. Idk what would now if i tried again
Sent from my SPH-D710 using xda premium

I haven't oc'd mine so I am not sure what it is capable of. Tomorrow I will disable the JD and flash a repack and see if that has any effect. It is frustrating because I love the repack rom's. For now I use mobile odin to flash a repack and boot to recovery if I want to nandroid then flash the stock kernel back again.

I had it until I updated modem, and when I say had it I mean right after flashing an ics rom, and every time after the phone sat with screen off for more then a minute, can run at 1.6 no problem, don't see a point though

I was just curious because on the original epic I had sod on some kernels and that phones processor was terrible. It froze when I tried to overclock it. The next one I got I wad able to overclock and I never had sod. Just seeing if phones with not being able to overclock might have an issue right now.
If anyone needs any help with the epic touch hit me up on Gtalk @musclehead84

Are you using SetCPU? If so, don't fix screen off at 200-500.

Yeah we really meed to figure out what the heck is going on. For the last few days i've been trying to figure out why i've been having SoD. Im on blazer ROM and ive found out that if I don't flash a new kernel i'm fine. But as soon as I flash rouge 1.4.1 or 1.4.0 I get an onslaught of SoD. Things ive tries to fix it are:
-Installing set CPU and raising the voltage and changing gov. to on demand.
-taking all the init.d scripts out of the blazer ROM zip before flashing.
-I find that when the phone is on the charger it never gets SoD
That last point leads me to believe that it has something to do with deep sleep. Because when the phone Is plugged in it isnt allowed into deep sleep mode and idles at 200Mhz. Ill be looking into this more tonight. If anyone would like to work with me i'm always in the e4gt ics dev channel on freenode.

Do you run Juice Defender or any other power saving app? I am on an ICS rom and when I flash the repack, almost everytime I power off the screen I get an SOD. I am getting ready to disable JD and flash the repack and see if that makes a difference.
UPDATE: I disabled juice defender and flashed the repack. Have gone for 40 minutes without an sod. I am going to enable the jd but change several of the settings to see if that will allow me to run it with the repack and not get frequent sod's

you know....oddly enough I did install juice defender a few days ago....then flashed the 1.4.0 kernel and thats when everything started.....BUT ive since reflashed the rom a million times without re installing JD and i still get SoD with the 1.4.0 kernel
If you continue to not get Sleep of deaths...will you try flashing 1.4.1 or 1.4.0?

Just to clarify, does the SOD issue include texts/calls not going thru whatsoever while phone sleeping on or off charger for more than ten minutes? I get this with any ICS up to 06, when people call me it goes to VM directly, texts go to sprint limbo. Or, do these leaks just horribly handle low signal areas? I was on stock 85 prl, and signal was about 0-1 bar sprint and force roamed on 1xrtt for 2-3 bars... since this screwed me on a couple important calls I reverted to EL29 and flashed 111115 PRL... anyone have these issues with ICS, or is it just my **** reception and network issues?
Oh, and I SWEAR... no conspiracy theory... but anyone notice pretty much all samsung leaks have issues that are magically fixed for final release? Epic froyo, GB, now ICS on the Epic Touch... just sayin... its like they dont want us daily driving these... just use em enough to beta test (really this site should be renamed XDA Beta Testers)?

The issue you are talking about sounds more like the loss of service bug that has plagued some of these phones. the sleep of death is when the screen turns off and then you can't get the phone to come back on with out holding the power button for 10 seconds or pulling the battery. I am still doing fine. I enabled juice defender but selected advanced settings and disabled jd from controlling the auto sync. I set the controls options to default. So far I haven't had an sod. I will see if I can flash those repacks but I am not sure if it will work right since I am on an ICS rom.

SoD almost certainly involves the cpu going into deep sleep and not coming out. I have never experienced this issue on the E4gT on any rom/kernel combo, but I dealt with the issue extensively on the nook color it it's early days. I can definitively say that because a large number of users are using the repacked kernels and are not having SoD issues, then it is 100% NOT repacked kernel related. SoD is caused by voltage issues or cpu step switching problems. The repacked kernels are identical in these regards across all users, therefore the repacked kernels are not causing the SoD issues.

I've had the SoD a few times on FC05 and FC06 - I'm in the process of downloading FC07 right now. It doesn't happen often (3, maybe 4 times in a few days) and I cannot pinpoint any actions preceding it. I no longer have Juice Defender installed. It's odd though, I've also had problems receiving Kik messages after a reboot. My girlfriend sent me a few messages 6 hours ago that I didn't get until I opened the app, then it's back to normal. This is a pretty regular problem. It's like I have to kick start the app before it starts. But over that 6 hours I streamed Pandora just fine and Gmail has been syncing as normal.

It is a puzzling issue. I also don't think the repack kernels acutally cause it to happen but there is something about the issue that causes it to happen frequently when using a repack. I can go back to any of the stock kernels and it works fine even with juice defender running. That is why I thought perhaps it was some app like juice defender that was causing it but people still have the issue without juice defender. Fortunately for me it seems the fix was to disable juice defender. Unfortunately for my battery though.

Well so far it seems that ive found my solution. All i did was grab the 1 click Odin to Stock Rooted EL29 and wiped everything. I wiped internal storage and flashed back to rooted stock with odin. Then i Odin'd a kernel and flashed back to blazer rom and then had to re odin the rouge kernel that was originally giving me issues. So far all is well. I suggest giving it a shot
