Probably... There is no reason to have the suspend frequency this low, in fact it will probably drain your battery more than having it set higher because if (reality: when) there are tasks to run well sleeping, the processor can't ramp up enough to do them quickly then go back to deep sleep and the processor will run more cores for a longer time using more battery than a short, high-speed burst of use.

If you are going to set the suspend frequency, set it at 702 Mhz at a minimum, but the reality is it's just a failsafe setting for a misbehaved or malicious runaway app. For the most part, there is no reason to change this from the default of 1512 Mhz.

I am using b47 with PAC-ROM 4.4.4 at first I lost my Wi-Fi. Just dirty Flash the rom and the kernel again it solved my Wi-Fi issue but the touch screen gets extremely unresponsive sometimes

[Nexus 4 General] acejavelin:
Flash the complete stock 4.4.4 images from Google (NOT a flashable ROM), reflash recovery, then flash ROM, gapps, and custom kernel. I know it's a pain, but it should fix the issue... I had similar issues and this fixed all of them.
[Nexus 4 General] o-w-a:
thanks but I'll pass. I have the WiFi working fine and the unresponsiveness occurs only once in a while when its on charge so I'll pass
[Nexus 4 General] acejavelin:
Actually, if it only occurs when the phone is plugged in try a different charger or cable. I have seen a malfunctioning charger or cable cause an unresponsive touch screen

I use cm11 installer version (think its at m7/4.4.2 release now) and had terrible battery life. I flashed hellscore kernel and the battery life has improved drastically. However, my WiFi randomly stops working and I have to enable/disable airplane mode (a fix I read somewhere in this thread). I am using b46 kernel version. I will have to wait until the M8 release or upgrade to a nightly in order to use b47. Does b47 fix this problem?
[Nexus 4 General] fozzie:
Android 4.4.2 => b46

Android 4.4.3/4.4.4 => b47 test
[Nexus 4 General] [AFX]:
So I should be ok to upgrade to b47 then. Does it solve the WiFi problem? Either way I'll give it a shot.

I assume you meant "greater than or equal to"
[Nexus 4 General] fozzie:
There isn't actually a WiFi problem; issues arise when people flash the wrong build of kernel onto the wrong OS version ;)

You might need to dirty flash your ROM first, just to ensure you've got all the correct files on there.
[Nexus 4 General] [AFX]:
No problem. I'll see what happens when I flash b47,and if for whatever reason its still acting funny, I'll redo my phone.

Slightly off topic: what's the best way to save /sdcard and app data? I've just been copying /sdcard to PC but I would like a better solution that savess this and all app data/info/settings so I can restore it right away.

Edit: flashed b47, lost WiFi completely. Got b46 working again and WiFi restored.
[Nexus 4 General] RASTAVIPER:
As written before, b46 and b47 are used for different android roms.

So, how did you decide to flash both kernels for same rom in the first place?

I was guessing that the user who replied to me meant "greater than or equal to" depending on the android version I am using.

I'm still having the issue. Turns out i was using a 4.4.3 radio on 4.4.2. I downgraded to the proper radio but still same issue. I'll dirty flash CM again and see what happens.

Basically, when I connect to WiFi and walk away from the hotspot, and then try to connect to another one, WiFi stops working until I enable/disable airplane mode or reboot the phone.
[Nexus 4 General] mymeatb18:
Same exact thing happened to me. It's not a kernel issue. I will look for the fix.

Edit:

[quote name="mymeatb18" post=53627657]Forgot to mention that hotspot doesn't work anymore either and I do see the bug of not being able to reconnect to wifi<br />

<br />

<br />

Did you got error message when you enable hotspot and wifi isn't working till you toggle airplane mode or reboot? If so this is not a rom issue, some think it's cause a recovery issue, you can search in the TWRP thread for mako and hammerhead.<br />

<br />

In case this is your issue, you can delete with a root explorer <br />

/data/misc/dhcp<br />

/data/misc/wifi<br />

Delete while dhcp & WiFi folders<br />

But do a nandroid first and note that you have to set your wifi networks again.<br/>

So i dont have to flash wifi fix on b47 if using 4.4.4 right?

Also is it ok if i just flash b47 over b45+wifi fix?

Thx
[Nexus 4 General] Rohit02:
No you need to remove the wifi fix.. See do this.. Use awesome kernel cleaning zip from N4 android section(search for it) and after cleaning flash b47. You need to have the latest radio 1.03 and a 4.4.4 based ROM.. DONE!! :D
[Nexus 4 General] satriamau:
So if i already on a 4.4.4 based rom and the latest radio, i just flash the kernel cleaning zip and the b47 right? No wipe needed?

Thanks!
[Nexus 4 General] Rohit02:
Yup.. Absolutely.. Buttons are right there.. ;)
[Nexus 4 General] T-luvR:
Thanks for reply but i want exactly to know if it changes the partition or what does it exactly install and remove! And how it changes partition if it does
[Nexus 4 General] fozzie:
Open up the zip and read.
[Nexus 4 General] arffrhn:
Some custom kernel made some changes to the ramdisk and that is why it is recommended to flash stock kernel first. To reset the ramdisk changes. If I remember correctly, hells core does not tamper with the ramdisk.
[Nexus 4 General] go4fan:
Thanks for the kernel. Working great here for the most part.

The only problem I've had is on a few occasions when left on the charger overnight I will wake up and find the phone led flashing indicating an email text message etc but the screen won't turn on with the power button so I have to hold down the Power button and reboot.

Could be unrelated but I didn't have the problem with stock. Only setting changed in HKM is the Color Profile. Any suggestions? Using PA 4.41 Android 4.4.4 with b47.
[Nexus 4 General] satriamau:
I flashed that kernel cleaner and b47, but i unable to turn wifi on

So i just reflash the rom+gapps+b47. Everything is ok now. No wipe needed.

Btw, is b47 not supported by touch control? I tried to load the module but no luck.
[Nexus 4 General] Rohit02:
Touchcontrol app wont work as the dev have stopped deving.. u cn use rom ibuilt feature to lock n n kernel feature to wake the device.
[Nexus 4 General] acejavelin:
Clear data on HKM and reboot, if it still does it consider upping your minimum frequency to 384Mhz.
[Nexus 4 General] Kadazo:
May I know what's the default minimum frequency of hells-core?

As I open the HKM it shows 384Mhz so is this the default minimum frequency of hells-core?
[Nexus 4 General] acejavelin:
No, 192 MHz is the default... It sounds like something might be messed up in the kernel config... I would flash back the ROMs original boot.IMG, reboot, then flash Hellscore zip.
[Nexus 4 General] RASTAVIPER:
And many of us are using 81mhz as min.

What exactly is this "hotspot" mention about?

I remember you were the one saying that you were also having issues like me with CM11 and hells-core kernel, but i couldn't understand what this hotspot means!

My problem was present when i was connected to my home's wireless router, and i was getting out of it and the router wasn't accessible. When i was getting back in home, phone couldn't connect to the router, and On/Off button was grey, until i rebooted it.

So, do i have the same problem as you?

I really want to go back to CM11 but i can't live without hells-core or broken WiFi.
[Nexus 4 General] mymeatb18:
Hotspot is a feature in all Roms so other devices can connect to ur phone. If u have the WiFi error then u have hotspot error.

Just delete the two folders I mentioned. It fixes the WiFi issue.
[Nexus 4 General] tsiftsism:
Ok, thanks for clarifying.

I know the terminology, but i wasn't sure that we are talking about the same issue since i have never tried to share something with other devices.

Maybe you are right, and if i delete those folders mentioned will also fix my problem.

I'll try to find out if i can make a nandroid backup to an external usb drive with otg cable via twrp recovery, in order to quickly restore my setup if WiFi remain broken.
[Nexus 4 General] mymeatb18:
Yes I also had the WiFi issue but didn't notice as I usually turn off my WiFi manually. But I did see the WiFi issue by testing the scenario of going out of range. I just noticed the hotspot issue as I use that sometimes.

Deleting the folders will work and it did not cause any issues. Just had to re do any WiFi password as it deletes saved passwords.

[Nexus 4 General] Kadazo:
Alright. Maybe I installed HKM before flashing hellsc-core causing this problem.

Thanks!

I had d2tw enabled and lower the min frequency to 81mhz but there's once my phone screen froze and not responsive so I raised it up to 192mhz again and so far so good.
[Nexus 4 General] acejavelin:
No, you can install HKM w/o the kernel installed just fine, it will give you a prompt to download and install the HC kernel... Most likely there is remnants of old kernel settings.
[Nexus 4 General] [AFX]:
I just wanted to chime back in to say that after reflashing CM11 M7 properly and flashing hells core kernel b46, I still have the problem with the Wifi being killed after losing connection to a hotspot. I guess I cannot use this kernel for now, hope to see this issue corrected in the future.

EDIT: after deleting mentioned folders this problem has been corrected. Thanks for the fix!
[Nexus 4 General] kid.:
Hi everyone, I got a problem after flashing the b47, my nexus 4 just suffer from boot loop, it keeps looping the Google logo...

My steps are as below

1. Full wipe

2. Flash Purity 1/7

3. Flash GAPPS

4. Flash Hells Core b47-kk_anykernel

5. Wipe cache + dalvik

Is this problem related to the recovery I used? I am currently using TWRP 2.6.2.0.

What should I do to fix the boot loop?

Thank you for your help.
[Nexus 4 General] arffrhn:
You can try just flashing the rom and gapps first see if it boots up. If it does not, then the rom may be broken during download.

Also, updating your recovery to the latest is recommended too.
[Nexus 4 General] acejavelin:
And wiping isn't necessary...
[Nexus 4 General] kid.:
In fact, the boot loop issue occurred since b44. After flashing the kernel, I maybe able to use the phone for a few hours without any problem, but later on it may auto reboot and start boot loop......

Thanks for your advise, I will update the recovery and see if the problem continue occurred.
[Nexus 4 General] arffrhn:
Hmm that is weird. Try to increase the voltage see if that helps.
[Nexus 4 General] Kadazo:
That's weird coz I installed HKM right after clean flash of Android 4.4.4 it should not be any old kernel settings left there.

[Nexus 4 General] acejavelin:
Then it has something to do or your settings are incorrect/not default. Remember the Min/Max core setting in HKM is only for when the phone is sleeping, when it is awake (ie. screen on) the kernel controls this and can activate any number of cores it chooses based on the governor. I would look at what is using the processor and what is running, when the screen is on there is often things going on in the background, to really see, reboot and let the phone sit well doing nothing for a good 5 minutes, then check the processor usage.

I have the 04/07 Vanir build. Can anyone link me a download link of this kernel because I can't understand what version I must use.?
[Nexus 4 General] IseeDEADbodies:
You need the CM version of the kernel, since your rom is CAF based.
[Nexus 4 General] TheNerd:]:
I think you're wrong...... The min /max cores control the number of cores when screen on
[Nexus 4 General] 22sl22:
+ 1 I'm also pretty sure it controls number of cores online
[Nexus 4 General] acejavelin:
Hmmm... you mean under Hotplug? I was always under the impression that these settings controlled the CPU when the device was sleeping.

Hotplug as a governor is similar to ondemand except it takes cores on and off line quicker... Hotplug as an option regulates the number of cores that are active well the screen is off.

If I am wrong, I will gladly retract it, but this is how it was explained to me a long time ago by a kernel dev on another device.

Perhaps we could get [MENTION=647113]hellsgod[/MENTION] or [MENTION=3946657]xanthrax[/MENTION] to comment with a more definitive answer, I know I would really like to know.
[Nexus 4 General] arffrhn:
It is like [MENTION=4653206]22sl22[/MENTION] and [MENTION=5140864]TheNerd:][/MENTION] says, it controls the cpu when screen is on. Hotplug or hotplugging in the cpu tab is the kernel ability to switch off cores online controlled by the governor. Some kernel like trinity for example, has different approach altogether. Morfic removed hotplugging in trinity kernel so that there is always 4 cores online. He believes, by doing so, it can save the power wasted just to turn on and off the cores which would used up more energy rather than saving it. This was tested in a technical experiment and the result is that, having 4 cores always online doesn't necessarily means it will waste the energy. Instead, you can preserve the performance while not having so much energy depleted because of the hotplugging activity. Quite interesting approach but I still prefers hells core more because of the community here and the awesome HKM app. :)

Trying to bring it back are you?

Well you broke one unwritten rule, only use your own cat pics :p

I think the init.d folder looks nice but I found the /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq file showing 384000 instead of 192000 unless I modify the min freq in HKM which makes me doubt about the default min freq of hells-core whether 384mhz or 192mhz so is it a problem here?

hey all

looking to get some more battery life from my nexus 4 as it seems a little poor atm

im running CM 11-20140609 snapshot

android 4.4.2

i had cm before and i installed franco (not compatable with CM but no one told me that lol)

so i put hells core on instead. it did work but i lost the use off home button, wifi, and my status bar all broke so not very usable.

i re-rooted yesterday and installed new CMW recovery and CM 11.

everything running good now but im back to square one as far as battery life goes

looking to run hells core still as it looks good and the manager app is excellent!

when i click get hells core in the app though it brings up 2 options

b47-kk-4.4.3 or b47-cm-4.4.3

im assuming i want CM version for cyanogen mod but both options are android 4.4.3 when im running 4.4.2?

where can i get a compatible kernel for 4.4.2?
