New Rom & Kernel but still laggy - Xperia SP Q&A, Help & Troubleshooting

I wasnt satisfied with my SPs performance (had a Nexus4 before) and I started to root, unlock the BL and flashed CM11.
After that the performance increased a bit, but not for long. I then flashed the Williams kernel v2 and performance was good so far.
I am running on that configuration for a week now and the SP is getting more and more laggy.
Chrome Browser is quite unusable, games are impossible to play and Multitasking lasts ten to twenty sekonds to switch one to another application.
Can anyone help me out? Is there anything i can do to make the SP even usable?

buy the new xperia sp or z1
Ok i just kidding.
you can try flash stock 4.3 (.207) and relock your BL.
it work on my phone

Thanks but no chance, I'll never buy a Sony Xperia again...
OK, your suggestion should be the last option.
What kernel are you guys using?
Ever had a problem with that like a lagging device?

How have you installed Williams V7 on a locked boot loader??? I was told it was for unlocked only?

There are 2 versions of Williams Kernel. One is stock-based kernel, and another is for CM and derivatives. If it happens that you have a locked bootloader, choose the stock-based instead.
For locked bootloader
For CM11 based ROMs and unlocked bootloader

I tried lot of different ROMs on SP which includes MIUI, CM11, existenz, etc, etc but after 2-3 days of using always have one or more than one problem mentioned above! So I just flashed stock Jb 4.3 and Disabled lot of debloated apps from the Setting>Apps. Installed CLEAN MASTER app. Since the stock is best stable ROM therefore best battery backup no random reboot. Now waiting for the new firmware update for JB 4.3 which has already been released. I hope we are going to get it very soon and going to get a better performance! :good:
Please try Ultimate PureXSP and Ultimate BlackXSP
IMO Stock 4.1.2 is still fastest, just debloat it and it's perfect. I rather stay this and wait fixed 4.3 from Sony.

I found this in the Doomkernel post :
Xperia SP [C5302/C5303/C5306]
stock JellyBean 4.3 FW
.266 - v05, v05-new, v06
stock JellyBean 4.1.2 FW
.245/254- v02, v03, v04
.284- v01
bootloader unlocked
working fastboot
android app for overclocking like SetCPU (paid) or NoFrills CPU Control (free)
so how I can flash it and my phone is on LB ?
yes stock 4.3 got bugs but atleast the camera quality is far better then 4.1.2 whenever I install custom ROM or kernel to my Xperia SP its a kind of unstable i can't even run the full antutu benchmark it reboots at 21% no matter on what custom ROM/kernel i am running :crying: and system reboots frequently. Therefore, Now i flashed the stock 4.3 australia firmware and locked the bootloader now atleast i can run full antutu benchmark now matter how many times i run it! thats why stock is best with disabled debloated apps and obviously no Facebook app also! :laugh:

[Q] What the more stable build of CM11 for SP

I am not so sure, but I am currently using official Cyanogenmod M10 snapshot, and so far, it is stable in my opinion. A kernel of your choice here is Williams Kernel

Sorry I never had any experience, nor interest on using CM11s. However, flashing Williams kernel won't give you root. I am not even sure if William's kernel would work on CM11s But my guess here it will work, as Williams kernel is for Cyanogenmod based ROMs.

Cyanogenmod ROMs are pre-rooted. You won't require any rooting method after getting CM to run on your phone. But however, do note that CM uses Superuser rather than SuperSU.
I underclocked my SP to 1.2GHz and I really don't face any issues. I don't play any heavy games though by the way, so I can't really tell you the game performance. Things to note however, some people faces multiple issues after flashing CM11. Most of them regarding the ROM being very laggy. I hope you won't face this issue, as it is not quite clear how it happened.

build7 always brick my phone
hi
i'm trying to install build 7.
My phone has locked bootloader. Installed version is #build6.
I have used philz recovery to flash build 7. To flash #build7 takes 2 minutes long.
After flashing, i reboot the phone using reset recovery option of philz.
Phone gets stuck, black screen, without sony logo, and i have to reflash to .207 stock rom using flashtool.
What am i doing wrong?
thanks in advance.

I guess it just happens sometimes. When I first flashed build #6 with twrp, everything went well, but something must have got corrupted along the way as the phone was stuck on Sony logo, and the screen just went gradually from orange tint to black from there on with continuous reboot loop. Fresh install helped though. And I've done everything the same.
Go back to stock,root, install recoveries, wipe cache, dalvik and system and install build #7. Should work just fine.
P. S. Another question from me, maybe not entirely related to only this ROM, but to flashing ROMs while using link2SD in general, as I'm sure some of you guys are using it. Is there any way to avoid some apps getting totally borked after each update? I know you need to recreate the mount scripts after flashing, but it just doesn't work for select apps each time, and I have to go through a tedious process of unlinking each one that is screwed, rebooting, and relinking. It's getting annoying with weekly updates (Thumbs up MRSteve <3).

Not sure if it's an issue with the nightly build you were working with this time, or something's actually wrong with build #7, but I don't seem to be able to install any CM Theme. Each and every one of them seems to install just fine, only to spit out "Failed to install <appname>" notification after a minute.
Anyone having this problem aswell?

This ROM or CM11 Official ?
Wich is better ? Keep my bootloader locked and use that ROM or unlock my bootloader and flash the latest CM11 Official Snapshot (M11) ? Few months, i flashed CM11 for locked bootloader and I had lot of anoying bugs/freezes. Can I expect better with that ROM ?
Thank's and sorry for my bad english.
This ROM is completely stable, and has no apparent bugs whatsoever. The only thing I noticed is worse than stock is the battery life.

Why on earth did you do that!? You'll need a computer with you. You will sadly however, have to start from the beginning. Get a stock ROM .ftf, flash it via Flashtool, then start over (root, install CWM, flash CM11 weekly build by MrSteve555)
The reason why your phone is bricked is because you have flashed a ROM for unlocked bootloaders (this being said is the M11 that you updated your phone). Your device does not have an unlocked bootloader. It does not start up due to the kernel installed on your phone is not stock (cyanogenmod's official kernel of course). On locked bootloaders, using a custom kernel is impossible and will cause bricks.

I haven't used Official CM11 on my SP, as my bootloader is locked, so it's not me to ask. For me, the phones eats through battery really fast, with screen on, it's like 10 minutes for 1%. Definetely not a days worth of use when gaming.

It's okay to use Williams kernel even if you're on Kitkat. As long as the ROM requires stock kernel, the Williams kernel will work as well.

Only you know your situation better than anyone else. I suggest you try out a couple of ROMs and kernel combinations and see which one works best. Also, try installing a minimal Gapps package to reduce battery consumption, such as this one: http://forum.xda-developers.com/showthread.php?t=2779598 .
You could also install one of the few custom kernels for XSP and underclock/undervolt it. Be cautious though.
Hit thanks if it helped! Godbless!
