Need help / recommendation : X10i has became too slow - XPERIA X10 Q&A, Help & Troubleshooting

Hello friends,
never tried rooting any android as of yet, but my phone has gone painfully slow now forcing me to do something.
i would be grateful if i get a help/ recommendation is choosing the ROM.
I want a light, fast and stable ROM but don't want to scarifies any features ( e.g CM7-ZMOD CYANOGENMOD 7 says no tethering (both wifi/usb) )
my only usage are call/sms, occasionally taking picture, videos & playing some light games like candy crush.
im zeroing on ****FeraLab*** FeraKernel-JB-v4
update:- frealab, 720p video playback don't work and so as capture
please suggest me if in going in right direction is it advised to install JB ROM in X10 kepping the stability POV ?
Thanks in advance.

I wouldnt flash a jelly bean Rom, but if you did so it would also handle your tasks.
For all features I would recommend DiXperia 7 and finally you could use a gaming Rom as they have least stuff but best preformance. On jelly bean you could use xposed as well

Ditto @keenofhiphop.
I wouldn't flash/install any ROM other than GB.
There are many reasons to install a JB ROM, but mostly those looking to install a JB ROM on an XPERIA X10i never identify any real reason, they just think they need JB+
The best ROMs and Kernels for the XPERIA X10i are all GB based and to date I know of no ICS+ Kernel that supports 2D Hardware Acceleration for videos and etc. This may change if @FeraVolt and others are able to modify the Adreno 200 drivers to support 2D HW acc in ICS+
I too would look at a gaming ROM for the least system overheads.
There is the newly created GB FeraKernel v14.1 and FeraLab ROM v30.2 which I have tested and know to have a very responsive UI and good 720p 2D video playback.
I use DoomKernel v6 and @Tof37 X10S ROM (FeraLab based) with a heavily modified build.prop which provides a similar experience to FeraKernel v14.1
Having a Class6(or greater) microSD card and offload(I use Link2SD) as much as you can helps, as the X10i built in flash only has a read of ~6MB/sec and a write of ~3MB/s. Compare this to a SanDisk Extreme 64GB card which I ran for a while in my X10i which gives a 20MB/sec read and 13MB/sec write.
I'm currently using a SanDisk Ultra 64GB card which provides a good cost/performance ratio. 17MB/sec read, 7MB/sec write

thanks @Dr Goodvibes and @keenofhiphop for inputs.
I was thinking as JB is more polished and is newer i am thinking to go for JB if i flash.
but since HW playback & recording is not available i would probably look something else other then Feralab...
i have 1 doubt at this time... do we have to flash with the latest Kernel first & then the ROM ? is it possible to revert back to old kernel at later if i change rom ?
sorry for my noobish question but im flashing any android rom for first time

True, JB has many advances in performance, security and interface options/features.
However, hardware development/drivers for the XPERIA X10i stopped at GB 2.3.3
Many of the JB performance features do not translate into real performance gains for the XPERIA X10i due to hardware constraints.
Thus GPU HW acc and camera (which is bound to the GPU) suffer. Also WiFi is 802.11g, Bluetooth is v2.1 and etc so any JB ROMs have to be retro fitted to accommodate these services.
Many developers do an excellent job of building JB ROMS and Kernels for the X10i, but they do come with some caveats and these should be understood before one installs a JB ROM.
One good thing about the Sony Ericsson XPERIA X10i is that it's a very good development platform and very robust and very hard to knowingly hard-brick the device. It can always be restored to a Sony Ericsson default firmware of GB 2.3.3 at any time, with a PC and a USB cable.
When you root the device you can install CWM recovery from flashtool and then using CWM Recovery to backup your system and thus provide a quick and easy way to restore a ROM even when you're not able to successfully boot Android, but still have access to CWM recovery.
If you can find an old version of flashtool circa v8, it has more features for the XPERIA X10i as newer version of flashtool don't have these services as newer phones have rightly become the focus of Flashtool now.
I would suggest FeraKernel v14.1 and FeraLab v30.2 ROM as the best first ROM, as there is currently a lot of development around this ROM/Kernel combination and thus you'll have tens of people to assist you if you have questions.
This doesn't have to be a long term commitment as you can always flash another ROM/Kernal at any time, but it does expose you to a better understand of flashing Kernel/ROMs and etc.
I would also suggest looking at unlocking your bootloader on your XPERIA X10 as this has no negative impact that I know of and also allows you to install a greater range of ROM/Kernels which rely on having an unlocked bootloader.

Thank you very much, @Dr Goodvibes, those are exactly the words boosted my confidence to go ahead & flash. and as you said once i finish a single flashing process successfully i would be more confident in future flashing,...
:good:

A word to the close: @Dr Goodvibes I totally agree to you, a found that in jb you could notice project butter and it worked really smooth but! it drains the battery a lot more than GB and there are several problems with hardware as mentioned with camera and gpu.
I think feravolt is one of the last Devs that really develop in the X10 but I could never really be stratified with his roms, as they look very mixed up from different mods. Which is off course a cosmetic thing but I didn't like it. I first flashed DiXperia 7 about two years ago and was totally happy with it, but as I am I was not stratified because flashing is fun I can say I flashed my X10 probably about 150 times, maybe more.
It was pure fun
Two months ago it finally gave up, it's on fetakernel and doesn't get flashed by Flashtool. (it was time for a new one)
However I hope you'll have a good time as I did and unlocking the bootloader only had advantages add is easy and offers you full customization.
And have a look into uot kitchen
It was the best about GB^^

flashed with v30.3 final & camera fix & latest kernel 15 beta one. ... great performance boost compared to stock !!
i failed to install XRecovery though but CWM is installed so i am fine i guess...
