Super Slow Xperia Arc

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........

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

Stock ROM VS Custom

I've had this phone for nearly 2 years now. In that time I've tried many (probably all) custom ROMs for it.
It's now just a gaming phone, even then I don't really play games.
With custom ROMs there's always a downside. I'm considering just debloating and rooting the latest stock.
I've been on G2JB for quite some time now and it's been randomly rebooting recently. I could keep on experimenting with ROMs and kernels but I just want to have something I can have that will work.
I can satisfy my flashing addiction with my new phone.
So my question is: is (debloated, rooted) stock good for what will be purely a gaming phone?
I can't be bothered with keeping up-to-date with the latest kernels and ROMs.
I've never been on completely stock everything, the day I got my phone I unlocked my bootloader and installed a custom ROM.

to answer some stuff quick:
-KK is a hell lot faster than ANY ics rom with & without apps on it. maybe currently its a bit sluggish but thats because ION is in ACTIVE development. but its getting better & better every update. for latest version of LX im really amazed. if you know that ''It's Can't Be Lighting Fast & Cool ROM'' you know nothing about KK experience & bro KK is even optimized for low end HW. your sentence is wrong. KK runs a lot faster & stabler than stock ICS!!!! the thing is that some drivers are not meant for KK & make some things not work superb like wifi. i have much app installed & phone still super fast. i dont use fackbook & i guess its fb fault that phone become laggy. (fb works good on ICS?? did you making jokes?? )
you should try KK instead just only talking about it. i think u have no idea (what u talking about ) also use some good rom like LX, to many half baked roms out there
- dev porting apps mostly to their systems using. mostly they use the newest.
- sony apps porting to same os KK apps port to KK is MUCH easier than to JB (very hard many code changed / missing in JB)
try KK bro & report me bak

Thanks For The Right Answer..
hi there bro... thanks for useful reply... i don't have much experience in KK roms... i will definitely try it later... so what rom do you use?
Legacy Xperia 443? >>> http://forum.xda-developers.com/showthread.php?t=2545354
is that optimized rom? i just can't imagine how KK can be better then ICS... maybe it's really optimized for 2011 xperias...

KK (aswell as JB) is better because it uses the new 3.4 kernel. this is a power pack. ICS still rocks stoneage 2.6.2xx kernel.also its CM based which is hold close to stock android = more power for you. one of kitkats pros was project sveltje which wanted to make sure that the latest OS of android even run smooth on low end device (512 mb ram) it also benefits our devices.
personally i use latest LX 4.4.3 rom (with sony home, media apps & sliglthy sony style framework by me) because its keeped clean & its updated frequently (not abdonned after 2 builds ) but the newest versions (after 19/3 build) are all ION based & with hints . some bugs here & there, new bugs comming (because of active development) if you want just check out kitkat, use the 19/3 build as it is the last PMEM one & gives most stability in kitkat on our device.
if you just want to upgrade your rom to use it as daily driver & dont care to allways have the neewest, then use CM10.1 (also LX) will give you best mix of speed from new kernel & its the most stable of all JB roms for our devices.
just to mention in coparsion to ICS: battery will get down faster & wifi isnt perfect (i have no problems). also camera is much better on ICS. (mostly due to lack of proper drivers.)
take 2 hrs time, do a backup of current rom (recovery), the flash LX kernel ROM & gapps of choice. N# experiece yourself. im really amazed how far our phones got . in case you dont like you can just flash old kernel & restore backup (or go to stockkernel via falshing stock ICS ftf via flashtool, then install xparts, install CWM --> restore backup)
dont forget to follow LX install instruction EXACTLY good luck

@gius321
I know you're no newbie.
It pains me to see that you've not tried out any kitkat ROMs all this while.
May I suggest a particular ROM.
C-Rom version 5.6 KitKat 4.4.2
Try it.You will like it.

[Q] Looking for a nice experience.

Hi,
I'm pretty new on XDA, and pretty new on the Android customization world (I only installed CM10 on my old HTC M7) and i'm currently looking for a good ROM - kernel - theme to install on my LG G3 D855 (European version - 16GO / 2GO Ram). I want a rom pretty clean, if possible in Lollipop, with good performance because i'm playing some power consuming game (X-COM, which in mt stock version frequently shut down my phone because of overheating) and customization capability. I did look heavily on different guide , ROM list, etc ... but i'm having trouble to find what each ROM really improve from stock experience.
Plus, considering i don't have many experience here, i probably don't know where to look exactly to have some review for each ROM.
Side question, i want to do all root / install / flash from my work, where i work on Ubuntu 14, will i have some trouble to intall drivers / software used to flash / root ?

"upgrade" z1 compact

Hi everyone,
i have a xperia z1 compact phone and i'm a newbie in the world of custom rom, kernels, ecc..
A few days ago i flashed a new custom rom and the phone is working pretty well, but i have a question here..
Can i use a stock firmware (let's say original lollipop 5.1) with just a new kernel?
I was thinking about not installing a completely new rom but just a new kernel and the xposed installer to change something on this phone, is that possible?
If android releases a new version of android and i upgrade my version, do i have to reinstall the kernel? And some apps from sony's firmware are quite useless (at least for me), could i delete them just like a new rom? (ofc with root)
I just want a stock firmware with a new kernel that can use less battery possibly.. I don't need overclocking or stuff like that, just battery life i would say..
Sorry my bad english though and thank you all for your attention!

There are at least a couple of custom kernel options in this forum. Check ' development' and 'original development' threads. You can usually tell if they work for stock if they have either 'stock' or a build number, (e.g. 368), in the thread title. Otherwise they may be CM based, and won't work.

Android 5.1 on this phone is .368.
5.0 is .270 or .242
The others are KitKat, (either 4.1, 4.2, 4.3, or 4.4).

For the first - as always - be 120% sure that kernel you want to install is compatible with remaining system parts.
Base thing - stock to stock, non-stock to non-stock, but it is not everything.
Changes between versions them may be too big to play together.
You don't put any tires to any car. You need to know that dimensions fit.
Same here.
