same here with the google damn camera, hellscore damn kernel, c-damned rom. no reboots while taking photos. themike, maybe try to not undervolt that much :) or maybe your device gone berserk of all those profile testing.

Im using hellscore b46 t4 with psx fatlady. I want to undervolt my nexus 4 for better battery n to cool it off. How to undervolt it and wat is the safest value for nominal binning cpu.(mine is nominal). Btw i used hellscore kernel manager to undervolt by changing global offset to -25000. Is it the good way to do it or any other way to uv.
[Nexus 4 General] xanthrax:
The kernel has been already UV-ed by default with - 100

Sent from my Darkside of LG G2
[Nexus 4 General] GruZone:
Thats the way to do it.

safe zone? There is no such thing. Not all N4 devices are the same, some can handle more UV and some cannot.

only remember, hellscore is by default UVed by 100(000).

[Nexus 4 General] iliyas10:
Ok so no need to uv further as ive did -25 more? Shud i revert back?

Thanks. These are my settings after UVed

New screen is installed!! Unfortunately the touch screen was acting kind of weird. It would only work while holding one finger on the screen and dragging/tapping with another. Wen I rebooted into recovery however everything is normal and everything is normal in the MultiROM screen. I just clean flashed the ROM/kernel and wiped the cache/dalvik. It's currently rebooting and rebuilding the ART cache; I'm hoping it will be fine when it reboots. Does anybody have any ideas?

I haven't used the Google camera for a long time: I bought a copy of CameraZoom some time back, but when KitKat arrived, the flash would activate either side (!) of the photo being taken, so I uninstalled and moved onto A Better Camera. I filed a report, but CameraZoom are more focused on eye-candy postprocessing, rather than taking the shot itself.

I was playing with the test kernel, and here the effects which I faced ..

Camera is laggy ( tested back with stock and franco, where the the lag was missing ).

This morning, the phone was like it is working on 2Mhz single core. I rebooted and everything was ok.

I am using default UV -100. Tested with -75 instead -100 - the same.

Now I am running the stable kernel, to compare the results.

[Nexus 4 General] 1ceb0x:
well.. kernel is fine. i run it on my n4 for more than 6 months now and i went through a lot of test versions and derps and fixes etc. b46 is stable, running great, almost the latest kernel sources, great features, insane battery life. still, if the kernel was running on an empty system was a kick ass one (better than many overrated kernels imho) but sometimes not everything can be perfect.

you see, you have kernel, android os and apps. in order for these 3 to work in perfect harmony, you need a good understanding of the whole process. your problem may come from some rogue app that was doing intensive background work (im pretty sure this is the reason) and that is not a kernel's fault.

if you are unsure what causes it, run a ddms (obsolete) from android sdk and you will see some apps spammimg the log like crazy *****es after KFC.

seriously, if you think that's a kernel issue, don't you think this thread was waaay to empty?

ps: kernel runs fine

ps2: did i mentioned it runs fine?

ps3: i think i did in the first ps.

Hey [MENTION=647113]hellsgod[/MENTION]

I noticed some weird battery drain, huge battery drain to be exact, only today.

I tried to see what is the reason through several monitoring apps (hkm monitoring tab, BBS).

Through hkm monitoring i saw that with no apps in background the cpu's are not stabilizing and i didnt see any rouge behaviour through BBS.

Can you look into it?

I dont really know what errors to look for so I extracted last_kmsg and cpu screenshot.

can i add txt file through tapatalk app? (Couldnt find the option)

Edit:

I also restarted my phone and these are the kernel wakelocks after boot.

a bit high arent they?

I have a problem, and i don't know if it's right to post here or on the Hells Core manager thread, but i'll try here

I Undervolted through the app, -25mv, ok there, then i decided to undervolt more -25, total of -50mv.

But today i got a reboot, ok there, so i thought "well, going back to -25mv, don't know why the hell i undervolted more"

But when i open the app, the volts were back to stock, and when i try to undervolt to -25mv, i get reboot, before was all ok, but now i can't undervolt anymore.

Any idea? [MENTION=3946657]xanthrax[/MENTION]

These results are pretty awesome I would say! Running b45 with the battery profile enabled, although getting these numbers is also possible when having all the cores enabled. I'm mainly very happy with the low drainage on low power requiring tasks (like spotify and Strava)

[Nexus 4 General] xanthrax:
well , you know that hellscore it is already Uv-ed by 100 , do you ?

that`s default on this kernel , -100 mhz less then stock android kernel

now , logically , going even lower might cause troubles

this is either because of your phone hardware or some certain apps doesn`t stand with this Uv-ing level

so , either keep it as it is or increase a bit more , i mean , go to -75

the battery won`t be affected , the heating only
[Nexus 4 General] xanthrax:
and most important and people seems to missed is that this hellscore keeps the phone so damn cool

battery life is always subjective but what we noticed is the phone stability ,cool , not really hot when running medium tasks and smooth enough

It's stressful for the battery to be near low charge or high charge. The low battery thing is a myth with newer battery technologies. Go ahead and charge your phone at 30% and unplug around 95%. It's healthier for the battery

I wouldn't worry about charging your battery doing long term damag... in fact I'd say its more likely you'll upgrade to another phone before you even see any changes from something like this.

The voltages don't go back to default, it's just that the sliders go back to the original position, they don't indicate anything, they're just a way to modify the voltages, exiting the app will bring back the sliders to the center. Focus on the values and you'll see that they remain the same after exiting the app while the sliders are centered.

So you had to +25 on your voltages ...

I am currently running Stock 4.4.2 [KOT49H] with hells-Core 46t4. The experience is so smooth when I swipe my screen I have to double check to make sure I am not holding a stick of butter. Most of the time it is indeed my phone.

I am going to flash Purity ROM. The build for this ROM is KVT49L. I notice some of you are running both this kernel and this ROM. I was under the impression that the build number of the kernel and the ROM should match to avoid bricking the device. If I am wrong about this, let me know for my own knowledge.

Which brings me to my question. Does this kernel work with both builds? Do I have to do anything fancy to get it to work with Purity? Should I flash the Stock Kernel [4.4.2 - KOT49H] before I flash hells-Core?

I feel like hells-Core, being endorsed by Satan himself, has supernatural powers that allow it to be used on any build. I also feel like flashing the stock KOT kernel after flashing Purity ROM prior to flashing hells-Core will, in fact, brick my device.
[Nexus 4 General] arffrhn:
This is a nexus. You can't possibly brick the thing unless you mess it up real bad. Very unlikely though so ease up mate. :D

The answer is that when you flash a rom, your current kernel is replaced by the kernel that comes with the rom. So, just flash hell-core after the rom. No issues at all. As long as you are using 4.4 or 4.4.x, then it's all good. Just make sure not to flash CM (caf) version on aosp roms though or you find yourself running into some issues. :)
