yes, C5306 works on different bands than C5303 and that means that you will have to find a suitable ftf to flash, do you want the 4.1 ftf?

Yes, because this new 4.3 upgrade is terrible.... to play a game i must charge the phone at same time, and even so, the battery drains faster than charges.
If you can provide a 4.1 link, i appreciate.

And a step by step would be great, as I'm a rookie on these matters

My phone has a locked bootloader (and can't be unlocked)

Thanks in advance

if you using 0.266 firmware try to upgrade it to 1.201 it might solve ur issue but if u didn't satisfied with what u get
u have to download a 4.1.2 .ftf file and flash it with flash tools (there are instructions to how to use it)
remember to get 5302 rom
warranty won't void unless u unlock ur bootloader ot give them ur device rooted and none of them needed for ur case

india 2.254 : http://d-h.st/hCj

1) download this ftf https://docs.google.com/file/d/0B986...hIMmJnWW8/edit ( thanks to @CorePrideX8 )
2) download the flashtool from here http://www.flashtool.net/download.php or https://unrestrict.li/flashtool
3) install the flashtool and navigate to the folder where flashtool was installed
3)open "drivers" folder and install the last 2(flashmode and fastboot)
4)transfer the downloaded ftf to the folder "firmwares"
5)open flashtool and press the thunder button..then choose flashmode
6)you will see the firmware on the left, choose it and press the flash button..wait until a message pop up saying to connect your phone
7)turn the phone off and while pressing the volume down button connect the usb(the illumination bar will light green)


On your guide,the part 3 is a little confuse for me.
That means to install what?
On step 3, there's nothing like that on the "last 2" items that look like flash mode or flash tool...
Also , on that tab, doesn't appear the option for Xperia SP

Skip the first steps and go to the 4th one

EDIT: oops, the drivers we want are the first two, not the last two
