[Q] Overclock kernel

Hey folks,
I've been looking to overclock my Xperia Arc (runnin ICS 4.0.4, build: 4.1.B.0.587) and I'm quite the noob at this so I'm looking for answers and advice. From what I gather, I need to install a kernel and I hear there are many options. One of the most popular one seem to be DooMKernel. I'm thinking about using that and I found this thread:
http://forum.xda-developers.com/showthread.php?t=1520654
Now, my question is, is that the most updated thread? Is there a newer updated DooMKernel lying around (that is newer than v5)? It's fairly difficult to navigate the forums and so I have a hard time finding all the right posts.
My next question is, if I were to install CyanogenMod, does it install a new kernel that allows me to overclock or is OS separate from the kernel?
And also, feel free to recommend me any other kernels. Are they all pretty much the same or do some of them have particular enhancements?
Thanks in advance!

1. The Doomkernel you linked have problem with some battery drainage, thanks to not using newest kernel sources (if I remember correctly?) and also that Doomlord haven't updated it at a long time so. Look for some other kernels before that one becomes stable enough!
2. The Cyanogenmod ROM requires it own specially developed kernel which can be found in the zip package of each initial release (CM7 - CM9 - CM10) and it have to be flashed through Fastboot before you are flashing the ROM in recovery. Follow instructions on Cyanogenmod homepage for each installation on your prefered device for more info!
3. If you're on Gingerbread, use Doomlord v22, for some amazing performance / battery and a lot of functions (underclocking, undervolting and some other stuff).
If you're on ICS, use latest Lupus kernel (version 8) - that kernel is a beast in every way and you'll definitely like it, it's stable enough to satisfy even you!
It's some difference between the kernels in speed, stability and performance / smoothness / battery life / functions, yes. You have to check them out yourself to find your own favourite.
Hope my answers helped you!

Awesome response, very helpful. Just one more question, do the CyanogenMod kernels have overclocking capabilities? Thanks for the reply, much appreciated!

Yup, CM kernels was created with overclocking and extended performance in mind, hence why Cyanogenmod ROMs are known with expanding the possibilities to some crazy ass performance and level boost (I have only tried CM7 and using it was like driving an Ferrari at 220 km/hour, later versions should be equal in their own specific ways).
Hope you got some useful answer on your question, dude!

I can recommend Sega Rush v3 kernel to use with your currrent or any .587 based custom rom, it can if you so wished be used up to 2ghz,( as could Doomlords V5 ), but be warned and advised to tread carefull with overclocking as you can cause permanent heat damage to, and even kill your phone if you overcook it.
I think the links to Doomlords v5 are down at the moment he is not active with it, so you may struggle to find doomkernel v5 to download, however if you look to the credits in the latest release of Sega v3, you will see him mentioned, take that as a good omen.
PS there are plenty of kernels to choose from, but I would say try to use one that is currently under active development, so that any upgrades / improvements are kept constant.
I can't comment on Cyanogenmods never tried any, but they seem popular enough, and look pretty well supported.You really are spoilt for choice, have fun

[Q] Recently switched over to Xylon Rom

Hi guys, I'm new on this board and I just wanted a ask a few question about this rom. Currently I'm using the Xylon 2.3.3 and I'm loving it so far, running beautifully smooth. I just got a question about the gapps, I've installed the 2013-2-15 gapps with all the photosphere stuff, however there is a newer version gapp which is 20130301, should I update to that?
Also is the kernel that it came with any good? or should I change it to AK purity like a lot of user have said to make it run a lot better.

It's safe to update, just flash over the current gapps.
As far as the kernel goes, most users report great things from the AK kernel so it's worth a shot.
For future reference, please use the corresponding Pre-existing ROM thread to ask such questions. There is no need to initialize a completely new thread.

thanks I will in the future. btw I was just checking the kernel version. It seems like the rom has already built in with the ak kernel purity.030. Correct me if I'm wrong.

If that's what your about tab says then yeah.

[KERNEL][ZL][EXPERIMENTAL] UNOFFICIAL DooMKernel {JB}(v13r2)[20130903]

Since DooMLoRD has stopped the development of his great DooMKernel for the Xperia ZL, and after his permission, I'm proud to announce
UNOFFICIAL EXPERIMENTAL DooMKernel for the Xperia ZL​
This is fully based on his original kernel sources at https://github.com/DooMLoRD/android_kernel_sony_apq8064
So, THANKS @DooMLoRD for his awesome job and for letting me build this unofficial release. Please, DO NOT REPORT BUGS IN THIS RELEASE TO DooMLoRD, since this is an UNOFFICIAL and UNSUPPORTED release.
This is an EXPERIMENTAL BUILD which has the following changes over the original one I posted on the other thread:
Built with Linaro GCC 4.7, custom compiled with optimizations for arm-cortex_a15
Compiled with speed optimizations (gcc -O2)
Removed profiling settings (slightly lighter footprint)
Removed debugging settings (slightly lighter footprint)
And other kernel options tweaks
It feels a little snappier to me, although there are no big changes in benchmark tools like AnTuTu (as you should know, benchmarks are not good for measuring the "real-world" user experience). I've been testing these builds for several days now, and haven't found any issues. But YMMV, report any issues you find with this experimental build that are absent in the original build (so I know it's related to this build).
You can follow the original thread for current DooMKernel at the Xperia Z forum here: http://forum.xda-developers.com/showthread.php?t=2172888. There you will find all the features of the current release, and discuss specific issues specific to this kernel.
The releases are for STOCK JELLYBEAN 4.2.2 firmwares. Currently tested only on 10.3.1.A.0.244.
>>>>>>>> Download EXP v13r2 for Xperia ZL: ZL-UNOFFICIAL-EXP-DooMKernel-v13r2.zip - 7.33 MB (build date Sep-03-2013)

General instructions and recommendations
As with previous releases, to install this kernel simply flash the zipfile in recovery.
MY RELEASE DOES NOT INCLUDE RECOVERY. You can use XZDualRecovery http://forum.xda-developers.com/showthread.php?t=2261606 from @[NUT].
I recommend you first BACKUP THE FOLLOWING DIRECTORIES:
Code:
/system/etc/firmware/wlan/prima
/system/lib/modules
Because the kernel includes new WLAN firmware and modules, and in case you want to go back to stock kernel, you can just flash the old kernel and restore your backups.

Been working great for me since release.

2 threads for one kernel? I'm sure if you combinate the experimental and release thread it's much better for orientation. People don't have to grab in 2 threads to find things they want.
Anyway thanks for your work to keep our zl up to date!

Well indeed this is something I considered when posting this experimental build. It has its pros and cons. I went with the option of creating a new thread to avoid cluttering the original one and possibly confusing users with so much information in one place (most users don't fully read a long OP). Since this is a different build which should take much less attention than the original one, I think it's better as a separate thread.
BTW, I'll try to release v15 for you guys today.

If you read op carefully you will know you have to flash NUT's dualrecovery.
Always the same, people don't want to read a op and ask questions they are already answered in op. Don't find words....

Try first to flash http://forum.xda-developers.com/showthread.php?t=2405925 this kernel. If sd card won't work, the problem is on sd card side. Format it in exfat. And be sure you are using stock Rom and no other Rom.

ive been using pro bam 4.3 rom and it has been great. except for battery running out a little fast but am giving it a few days for the rom to settle in!

PA 3.99
I have been messing around with a lot of 4.3 roms and pretty much all of them have the same stability. As for me, I prefer PA (Paranoid Android) 3.99 and PAC Rom but more toward PA 3.99 because it just seem slightly less buggy and bit smoother. Again, to each their own at this point since there is no official 4.3 for this device.

I've been using Hellybean , always you the latest, no issues. Love it.

As others have said its really just a preference thing. I have been trying out a few different ROMs, just to see which ones I like the most, especially 4.3 versions. I have been using [ROM] Unofficial | CyanogenMod 10.2 | Diablo Kernel [09-23-13] from ThdDude for the past day or two and havent had any issues to speak of. I really like that it has the Diablo Kernel compiled. I have noticed though that for some reason when I was trying to Flash 4.3 ROMs with CWM the system would boot but then go black and would have to go into recovery. I finally decided to give TWRP a try and havent experienced any problems flashing 4.3 ROMs. I have actually really been enjoying it and have some real respect for the developers.

stable 4.3 roms
The best I have used is the 9/26 aokp by whitehawkz along with uber kernel. Running 2.6.3.0 twrp. Especially like the active notifications with no problems.

There is no BEST and yet they are all the BEST. Members are expected to research and read through the development threads before altering their device. The only thing you will get here is a list of all the ROM's because every member has found what is best for them. You can get the same list by looking at the first few pages in development.
Thread closed.
Have a great day!

my daily
Ive been using this as my daily for months now. Only had a few random reboots and some of those are probably related to the fact im undervolting.
I have found the CAF version of the Glitch kernel (not the latest like an older version) to be extrememly stable in use with this rom.
Keep up the top work!

now that i think about it... a CAF wouldnt work would it... re reading the derscription of the kernel it uses some CAF sources (for msm specific stuff or used to anyway) but is built for AOSP (And its not as old as i thought i dont think, i forgot i built it from source on jenkins so its got a different namng convention to the ones in the actual glitch thread). If i can work out which kernel it is i will let you know as it is very stable and i have been using as my daily for months now with this rom.
Running up to 1.89GHz with 50ma (or more) undervolting for each step. only had a few issues initially while i got the undervolts right.
The full CAF kernels did not work at all (sorry i should have though about what i was saying haha!)

android 5 from android 4.4.2
I have a rooted, bootloader unlocked, with TWRP nexus 7 2013 (32gb wifi) running android 4.4.2 but have not installed a custom rom till date. Now if i want to flash a custom rom such as this one (android 5, while my nexus is on 4.4.2), all i have to do is download the rom from the link given in the instructions and flash it via TWRP?. From what i understand from the instructions, it doesnt matter what my tablets kernel number etc is, all i have to do is flash it via TWRP. Or is it that the new kernel is included with the flashable zip file, that i am to download.
Any input or advice is appreciated.
Thanks in advance
