Thumbs up safe to go back from 4.3 to 4.1.2?Yes

Can someone tell me is it safe to go back to 4.1.2 from 4.3?
Because 4.3 is worst firmware I ever tested,to bugy and lagy.
Its like 4.0 for xperia ray,now I feel that xperia ray is faster than this peace of sh..t!

Here is it little tutorial for downgrading if somebody needed:

1.Backup everything that is important (music,pictures,..)from internal storage to sd card or pc

2.Backup contacts on sd card

3.download stock TFT file from this thread http://forum.xda-developers.com/show....php?t=2311964 for all version of Sp
for Sp 5303 I'm using this TFT file https://docs.google.com/file/d/0B7GI...dDA/edit?pli=1

4.flashtool tutorial thanks to mrjraider http://forum.xda-developers.com/show....php?t=2658952

4.1.2 is faster than 4.3? I suggest you flash the ftf of Central European 4.3.

I'm on CE and sometime I feel like it's flying and sometimes it's so slow I don't know why.
I was flashing 2 times and always is a same.
I'm getting lots of camera stop,settings stops...
And what worries me most is heathing of the phone when I'm browsing net
And I have strange power offs when phone charging.

None of these happened to me... phone is a lot faster and stabler than with 4.1.2
It's not the firmwares' problem

I already downgraded my sp to 4.1.2. With 4.3 it was unresponsive, often freezing, slow opening apps, last night i had to "manually restart phone"(i am not sure how it is called, you open phone and stick pen in little hole until phone restart itself). I used this guide:
http://xperiafirmware.com/8-firmware...peria-sp-c5303
So i am on 4.1.2 until new JB update or hopefully KItKat.
Nama izgleda uvalise neku verziju 4.3 koja ne radi bas najbolje...

I'm downgrading right now to 4.1.2.

Nikad vise necu kupiti nijedan SONY uredjaj, kad imaju programere krembile.
Nije ni cudo sto su napisali da je KitKat under investigation, jer su jedva nabudzili i ovaj 4.3)

Da se vratim ja svom losem engleskom jos ban da ne dobije.

Xperia Sp is mid-range phone and it seems like Sony care only about their flagships and that's shame. XSP is great phone it just need nice update to improve camera and fix poor WiFi. I expected a lot from 4.3 and now i am disappointed. I will wait couple more months to see if Sony release new updates to improve camera, fix wifi, fix bravia engine, hopefully release promised KitKat. Then when they officially stop support for xsp i will unlock bootloader install cyanogenmod and i am pretty much happy with that .
I am not sure if other manufacturers are better with updates. So next time probably Sony's phone again but only flagship.

consider to root your SP instead if you really want to find fixes for that.. there is a lot of TUT here to learn and to make improve your phone, why not explore?..

I know everything about rooting because I have Xperia Ray with a custom rom and kernel with a root
I like to explore and try something new, but now for SP we don't have lot of good roms and because of my warranty I don't want to unlock BL.
I open this thread because system partition is different in 4.3 and I didn't know is it safe to go back to 4.1.2.
I will stay for now on 4.1.2 until we get update for 4.3 or Sony release source code for 4.3 and we get stable release CM10.2 with radio
