Hello everyone,
I am running the STOCK 2.3.3 rom (verizon) but using this kernel designed for stock 2.3.3 (here)
I can adjust the cpu levels just fine, but no matter what governor I choose it stays at the maximum level, as if in performance mode. I've checked with a few cpu-monitoring apps and nothing seems out of the ordinary at all. The phone also seems to be laggy in games at times, as if there is something running in the background. (But no unusual processes/apps are running)
It was working pretty good yesterday, but I don't know if it was maxed or not at that time, I didn't notice until today. So, is this a kernel problem? Is there another recommended kernel that can overclock properly using the stock ROM?
I ask because I can't find any tutorials on how to install a recovery to flash r800x to install a new rom.
Thanks for reading! I can post more information if needed.
I "fixed" it by flashing a JB kernel and ROM... For some reason, even after switching to the original kernel from the .ftf file it would still stay at max. I'm now using lupus JB v8 and paranoid android and all seems to be well.
Hopefully gaming won't be too bad. x)

Hi guys! I just bought an Arc S, and it's totally awesome. BUT, even if I like the design of the stock ROM, it really can be improved. I always have around 60 mb of free RAM, and you can imagine the result
May I use doom kernel ( or any other kernel ) without flashing a new rom? Would I have improvements? Do I get more free ram?
Thanks in advance, I'm trying to learn everything I can about modding this phone, I had a Motorola and I spent the last months tweaking it, now it's time to start all over
If you've unlocked the bootloader, yes. Any kernel thread OP will advise what version of android the kernel will support, or if it's specifically for a certain rom(i.e. MIUI/CyanogenMod roms). Generally, custom kernels improve performance and add features not available in the stock rom such as call recording, various schedulers, overclocking and so on. Battery life tends to be better with the stock kernels though.
thanks! and specifically, if I want to stay ( for now ) with stock rom 2.3.4 which kernel would you suggest me to try? i'd like one with smartassv2 governor, i heard it's pretty good
Doomkernel is your best bet there, tbh.

Hi All,
My Xperia Arc ( LT15i) is super slow.
Its much slower than my old HTC Desire.
I have done a Factory reset and a fresh update but still slow.
I am on Android 4.0.4 and using stock Rom build 4.1.B.0.587
Please advise any workaround.
If nothing, I'll try to root it and install AOSP Jelly bean rom.
I do not care if I have Jellybean or ICS, I just want the phone to be fast.
Does the custom roms really make a big difference ?
Thanks .
There are many custom roms for xperia arc/s which are faster than ICS and GB.
They are stable/alpha/beta roms. That is your wish to decide to install which ROM.
Look at the following thread - complete guide about kernel/roms/root/guides........
http://forum.xda-developers.com/showthread.php?t=1653188
Hit "Thanks" if anyone helped you.:good:
Xperia Arc LT15i
Rooted/Bootloader Unlocked
Running Jelly Bean - FXP139/CM10
I've tried Milans ICS, it's quite fast.
timescape ui is really laggy. do vanilla android like cm9/10 or aokp will do
cm9 --- interactive governer, overclock to 1.6ghz through settings -do not use task killers, they are pointless and eats some resource away even if they do get the job done
yes 1.6ghz is safe, i have this setting for a while
although cm9/10, aokp kernel drain a more battery than stock firmware

The custom JB roms are really fast compared to ICS.
I've also got a LT15i; here's a quick overview of the steps needed to get JB on your phone.
unlock the bootloader (there's an official sony website to talk you through this)
flash a decent baseband (use this thread http://forum.xda-developers.com/showthread.php?t=1688049).
Flash a rom of your choice - I suggest the latest AOKP from here http://forum.xda-developers.com/showthread.php?t=1859518
Things you have to know: -
How to get flashtool installed on your computer, and your computer connected to your phone.
unlocking your bootloader loses your DRM.
So my advice is read up on the stuff you need to know (if you haven't found out all this stuff already).
Then backup your SD card to your computer.
Then do the steps (1-3) to get the latest AOKP rom. This rom is officially in testing, but it is stable and fast.
Good luck.
P.S. I'm using Baseband 77, but most people recommend baseband 72.
I'm using Lupus kernel, but you should start with the kernel included in the AOKP rom.
After you are comfortable with CWM backups, you can experiment a bit more without worrying too much about data loss.
(more good luck )

I don't think so my friend...
I have switched from cm10 to Milan ICS for 2 day and i am dissapointed
I change because i want to use a stable rom and every functions r working great
But my decision is wrong, stock ics is the most stable but i can't play any games without lag :banghead: Ram is low and it very annoying
P/s: i miss my cm10
Hit thank button if i helped u
CM 10 with Lupus Kernel and besttt fix is rock solid.
Fast, stable (no random reboots) and everything works.
And u dont need 1,6 Ghz. 1 Ghz is enough on CM 10.
Go to arconium gb rom
Possible to root without unlocking bootloader
Thanks all for such nice advise.
I am not new to rooting, had a rooted HTC Desire for 3 years
Though, I do not want to miss on the DRM ( if it has any use ).
Is it possible to root without unlocking bootloader ?
I think it is but would be great if you nice people can advise me of the advantages and disadvantages of rooting without unlocking.
I would go with CM or AOKP.
Edit: As mentioned by ironlady, does AOKP/CM drain more battery than stock ?
Why ? I would assume that with all the extras of the stock, more batter should be consumed.
AOKP/CM are almost nearing AOSP and are no frills, why they drain more battery ?
This was my observation with HTC Desire. The HTC Sense based roms always consumed more battery than AOSP.
Thanks again.

Well, I don't know what DRM is for - something about "digital media rights"
(It hasn't affected playback of movies or sounds on my phone.).
It is possible to root without unlocking bootloader, but then you can't have an AOKP/CM rom.
You need the unlocked bootloader to flash the custom kernel required by these roms.
(
Flashing a kernel requires running "flashtool" from a computer. before flashing the kernel you must copy the rom to your phone's SD card.
After you flash the kernel, boot the phone and press the "volume down" button when the buttons light up.
This gets you into CWM recovery where you can flash the rom
)
I'm pretty sure that the battery drain depends on how you set up the kernel. If you over-clock, then more battery drain. If you under-clock then better battery life.
After all of this two more points of advice: -
If you try CM10, then use the Lupus kernel, and instructions posted by "besttt" to set up your phone nicely. This is a more tricky install.
If you try AOKP, then install it normally as described in the 1st post of the thread
(the custom kernel is a file called "boot.img" in the rom. You need to extract the file, and flash it with flashtool when you're ready to install the rom).
This is an easier install.
Enjoy
edit: nvm delete thread.
JellyBean isn't fully stable on our DHD/I4G just yet. There are always going to be some issues because HTC didn't give us a full 3.0 kernel for ICS. That could be the reason you are experiencing some lag. Kernels could also help you, try the KangBang performance kernel, although the kernel is leaning towards performance, so it could cause instability
I bought the xda app. Problem?
...
I can't link to the kernel (cause I'm lazy and on the xda app). But when you install a kernel wipe your cache and Dalvik Cache and then flash. That's the proper way of flashing a kernel

Hey thanks for the reply, yeah i successfully installed the stable and performance kernel from this thread : http://forum.xda-developers.com/showthread.php?t=1931386
But the gaming performance still lags compared to 2.3.5. I guess its due to not being fully stable yet.
I had an idea, what if i flash the stock 2.3.5 kernel? Would i get stock performance back or not?

You'll ruin your phone. A 2.3.X kernel I'd meant for that specific version of Android. If you mix versions (e.g. a Gingerbread kernel with a Jelly Bean ROM) you'll most likely get bootloops and your phone. At worst you'll brick your phone. Don't ever mix kernel versions. Also don't flash a Sense kernel on a AOSP/AOKP/CyanogenMod based ROM (or vice versa), you'll also have a phone that won't boot.

Hey, thanks for the reply. Yeah I was guessing it had something to do with the kernel. I tried a kernel yesterday not sure which one it was from memory, but when I put the kernel zip onto the phone and installed it through recovery it said install complete. But when I rebooted the phone it gets stuck on a black screen. I can't do anything else unless I take the battery out. I was wondering if anyone can give me a link to the kangbang kernel and instructions in how to install properly if the recovery mode isn't the right way, even though it said kernel updated successfuly. Thanks!

The only compatible alternative kernel for JB is the KangBang (at least that i know of). If you flashed another one, that might be why it booted to a black screen.

Hi guys!
Since I am not allowed to post on Devs threads, I post my question here, hoping for maxio1998 to see it, or anyone related to the Jelly Sandwich Project
I own a Xperia Arc. I had it upgraded through PcCompanion, to ICS 4.0.4.
Since it was very laggy and I had little rom space available, I decided it was time for a change. I unlocked my bootloader, flashed the Advanced Stock Kernel via fastboot and flashed Jelly Sandwich 8.0 in CWM.
The situation is that my processor is not running at its full capacity, and I don't know if it's because of my kernel selection, or due to some tweaks in the custom rom I chose. The max frequency is 806 MHz.
I don't want to overclock, but having it working at its normal 1GHz would be preferred, since it has become to be laggy after a while (not as much as stock ICS, but still...)
Attached is a picture using CPU Spy +, to show the magnitude of the situation.
Is there another kernel that you would recommend?
Thanks in advance

I'm used Advanced Stock Kernel with stock firmware. Advanced Stock Kernel not supported overclock feature.
You can get "No-frills CPU Control" from google play and adjust Max. Clock freq. to 1.024 GHz.

Thanks for the piece of advice :highfive:
It seems it solved my problem. I fastbooted ArcKnight kernel and with that app I'm now able even to set it to overclock if required.
Hi all, today I unlocked boot loader and rooted my nexus 7 2013 WiFi. At the moment I am sticking to stock ROM until I get more internet data from my ISP then I can flash a custom ROM.
Anyway what kernel would you recommended for stock KitKat 4.4.2 ROM in the mean time, or is it not worth changing and I'm better just waiting to flash custom ROM+kernel?
I was hoping for a more performance based one and would like to overclock both CPU and GPU, of course performance+battery contradict each other but if I could also have good-very good battery life and faster performance then even better.
Also what apps are you using for over clocking CPU/GPU?
Please suggest thanks

Best ROM/kernel threads are frowned upon at XDA.
As far as overclocking app, I use Tasker. I use it for setting the kernel tunables also.

I use elementalx with stock. Great performance and battery life.
