Hello guys,
since Google doesn't offer Android 6.0 for our Nexus 4 I flashed a current custom ROM (PureNexus) and a custom Kernel (Quanta V10) on mine.
Now I would like to undervolt it but before I start I still have some questions:
1. I want to make sure that I have a clear backup of the current status of the ROM, so that I can flash it back if something goes wrong when I set the settings on boot. The problem: I don't really know what app I am supossed to use.
2. Is it possible to deactivate some cores of the CPU?
3. Can I also undervolt the GPU?
4. Is there a better stability benchmark than Antutu?
I hope some of you can help me. Thanks!

1) The best way to make a full, complete backup is through nandroid. A nandroid will restore your phone exactly like it was if something goes wrong. Do this through your custom recovery.
2)On some kernels, yes it is possible. This setting would be found under the CPU hotplug settings in your Kernel manager if the kernel supports it.
3) To the best of my knowledge, Undervolting the GPU is not possible on the nexus 4.
4)I believe Antutu is the best one out there.
Just for your information, if you are undervolting for battery, you should know that it has been shown that you will be saving a negligent amount, and can greatly increase the risks of instability. If you are doing it for heat reduction, than I understand, but still please take it slow and be careful.

I have searched google for tutorial but nothing found.
Can anybody tell mme step by step what to do to increase my 528MHz?
Is there any tutorial?
And the final question, would overclocking really speed up Hero?
Hej, it is easy. You can download "setcpu" in xda: search it!
By using this app, you can overclock your Hero easily.
But overcloking seems to make the system sluggish...........(it was very smooth before)
I am using Villian 10.0.0.

Thx for the answer. So you don't recomend overcloking with setcpu?
No, something isn't right there, using the OCd kernels with SetCPU or OverclockWidget has improved performance of any ROM in my personal experience. Short guide, start of using values of min 350ish - max 650. Play for 5 mins, if ok, put it max setting up by one notch, play again. When it freezes up on you, you know you've gone one too high. You can also test how low u can set the min to save battery. Then start using the profile functions as well.
Mine runs pukka between 350 - 691, others can get 190 - 760.

I think the kernel has to be modified to allow overclocked frequencies..
I am in the same boat, I have the new official ROM, unmodified apart from root and would like to overclock..
Overclock widget shows 528mhz max, I assume SetCPU would be the same.. Is there an update.zip we can flash to have the stock kernel updated to allow the higher frequencies, but no other modifications?
Thanks in advance.
Yes indeed, they need to have a custom kernel. Are you using a ROM from here?... Most have their own overclocked kernels.
As far as I know you still can not take an update zip from one ROM and apply it to another without modifying it,... but I could be wrong. I was told the ramdisk could be extracted from the ROM your using and putting it into the overclocked kernel you want to use, this when the kernels were being made from source. Find out how to do that by searching for a guide on ROM cooking here on XDA.
However now with the official kernel released it might be possible to do it. Give it a bash. NANDROID FIRST!!!!!!!!!!!!
Hello Together,
Now after Alpharev-X has done such great work and open new possibilities for
us, i am thinking about rooting my wildfire for the purpose of overclocking.
Im happy with my stock rom, but would like to experience some
performance enhancement. But there are some things im not really sure about.
The first Question i have is:
Is it really worth to root the phone regarding to the enhancement of the performance that can be reached with a overclocked stock rom.?
(Im wishing to have some smoother menue performance while using some apps like k9 and other applications of daily usage, scrolling through contats etc,...... not gaming at all!)
The second Question i have is:
I have read about some users having problem after installing a custom kernel, like missing some functions like wifi or usb-problems and so on) Is there any user-experiance about which kernel is properly working with the stock rom mentioned in the title?
So it would be great if some user could post their experiance with overclocking a stock rom and which kernel they prefer and have tested.
Thanks in advance for all comments

If you don't want to switch to a custom ROM there's a really cool app called 'SetCPU for Root Users' which, after rooting your phone, lets you overclock your CPU as you wish. A word of advice, go easy on the Max CPU frequency!
Alpharevx doesn't root your phone, it just sets the S flag on your HBOOT to OFF. To root your phone take a look at this :http://forum.xda-developers.com/showthread.php?t=1130044

It'll still need a Custom Kernel.
OP, You can go for Arco's nFinity kernel modified by johseen for Sense ROMs (Listed first under Kernels List in the Wildfire Index Thread). Overclocking does improve general performance, but, its the gain is certainly not as much as the overclock % suggests,
to overclock, you´ll need to change the kernel, and to change the kernel, you must have installed clockworkmod , and to install it, you have to root your phone
Hey,
I see a lot of people using CM7 is this really the best one?
Also till how many mhz I can overclock on that one?
Yes Cm7 IS really great, in fact you can customize almost everything, and I really like that feature...
As for overclocking you can overclock I think to max of 768mhz(if I'm wrong somebody please correct me)...maybe you can a little bit more but I think it is kernel related...
Hope it helps,
Best regards

Irrespective of which ROM you choose, it is the kernel which allows (or disallows) you from Overclocking. Till date, there are 2 primary kernels which are available - HCDR.Kernel by Jacob and nFinity by arco, and both OC support upto 768MHz. (I think Deep-Knight has recently developed a new kernel for his ROM, which allows OC upto 600MHz)
Because of this, you can overclock your stock ROM also, if you so wish, by simply flashing a custom kernel.

Hi!
Which kernels can I use for original rom, if I want to overclock? HCDR, or Deep, or what? It will make the phone instable, or not?
Thank You!

You can use any. nFinity MC4 offers more features though, like Smartass Governor. It can be found here:
http://forum.xda-developers.com/showthread.php?t=995301
Else, you can use HCDR Kernel also, if you wish, and decide for yourself which suits you:
http://forum.xda-developers.com/showthread.php?t=798471
It shouldn't make the phone unstable at all. But, in any case, make a Nandroid Backup beforehand.
Thank You
Well M using hell fire .. Cm7 based ....
Which is stable till 729 Mhz overclock m using max 729 and min 490 (I guess)
Phone is Much faster than before and love playing angry birds
I read all the 2 posts, but Im not sure to change the original slow kernel, for a faster. All have some bugs, battery life, wifi, etc...
I dont know, which could be better for the stock rom, or which could be better than the original.
Anyway, I want to try one of that, but I dont know which.
How can I flash just the kernel? And also back up my programs with titanium, or mybackup?
It clears everything like the rom flashing?
Ok, I made it, its cool, and faster. Thanks for the help.
is the overclocking "app" in standard cm7? Or i must go to market or anything else to download it?

Hello,
I use SM-N9005 4.4.2, Baseband ver. N9005XXUENC2, Kernel ver. 3.4.0-1168347, Build number KOT49H.N9005XXUEND5.
It's a rooted, stock ROM somewhat modded with Xposed, Android Tuner app etc.
I'd like to flash a custom Kernel which will allow overclocking, eXtended battery life and some other neat features I hope more experienced XDA community will recomend.
So, what Kernel would you recomend as a mix of stability and performance for my stock TW rom? I am fairly inexperienced in these waters. Are Baseband version, Build number etc important when deciding on a Kernel?
Any advice would be welcome. Thank you in advance.

Try n3 by wootever, sneakykat and leankernel (last doesn't have so many features but is great for battery & performance) and my personal favorite ael kernel of course.
The kernels are pretty easy to flash just put on SD flash and wipe Cache & dalvik. So don't worry if you don't like the kernel just flash another one.
One more thing don't put two different apps for kernel settings (like Synapse & Trickster) on the device cause that may cause conflicts. Have fun testing

Is it really necessary to wipe cache & dalvik? I've read in several posts that it is not required as there will not be any benefit.

To quote Hacre, an excellent dev on other Samsung devices - wiping cache and dalvik for kernel flashing is like filling your car tires when the gearbox is ruined...

Thanks for your response. I've flashed the AEL kernel, recommended by you.
What are the immediate advantages I received compared to the default one? How do I get the most out of it now - what next?
Thanks for your patience.

That is pretty hard to answer cause I do not know what settings you prefer. (Performance, battery or a mix of both). Download Trickster from app store or set cpu (for last you have to pay though). At first I would try to set just governor and I/O scheduler. In the link you will find some information. Got helped not too long ago

No for Benchmark maybe but most of the time the phone will crash then.
Personally I take 22565600 as max and 300 min with intellidemand governor and deadline scheduler but every phone works different that's also why you won't find any "perfect" kernel or governor.
how can I flash the kernel I tried CWM to flash the zip file but it doesn't work please help me to find my solution
Hey guys, so every custom kernel I use the cpu is usually locked at the highest frequency. This makes the phone's battery life horrible and makes it very hot. Does anybody know why this occurs and how I can prevent it?
Thanks.

Install a kernel tuning app and see what cpu governor is being used, sounds like your using the performance governor, which will ramp your cpu to max frequency. I've read that some custom roms are set to performance after flashing a custom kernel, this is possibly due to a ramdisk tweak.
If it's set to performance, change it back to interactive (stock) or whatever governor you like and enable the boot option.

It doesn't automatically set to performance and I always change it to either interactive or ondemand anyway. Still keeps doing that

Have you set any scripts or flashed anything else or have some app/service running in the background? Something must be putting load on your cpu.
As you probably know, you can only flash a custom kernel over the stock boot.img if using stock ROM or if using a custom rom, you can only flash over the boot.img that came with it. If you change kernels you need to flash the ROMs stock boot.img first otherwise something is bound to go wrong in the ramdisk but easily fixed by flashing your ROMs stock boot.img again.

Appreciate your replies but I've already either done these things or have known about them and none of these have helped. I actually thought this was a common issue amongst Nexus 6P users. Anyway, app processes could be the culprit. Anything you can tell me that might help me identify the app causing the issue (if any)?

It's not a common thing that I'm aware of and I'd imagine it's a user issue, try Better Battey Stats app, it has a process menu or another app possibly would be GSam Battery Monitor.
