No,you need to use a flashtool and download a ftf file.Head over XDA.

Okey thx, maybe last question: I can't unlock bootloader because it's dependent (T-Mobile)

So without unlock, this downgrade can succesfully?

Yes,it will succeed.Only for custom ROMs you need bootloader unlocked.

My firend say i need to find t-mobile tft, because with the simple tft (D2303_18.0.C.1.13_CE.ftf) the phoning will not work.

Is this true?

If the device is network locked,you need the carriers firmware.

Ask on XDA,I do not know where could you find it. I am not sure that you will have problems if you exclude baseband when flashing.

You can use a generic .ftf firmware file - The only difference will be the pre-installed T-mobile features/apps will not be installed

Just make sure that if you have a D2303 version phone to use a D2303 firmware file

I uploaded the D2303 4.3 generic UK firmware to XDA if you need it

Re: How to downgrade to 4.3?

Thommo — Sun, 05 Oct 2014 12:11:04 GMT

Install Pc Companion

Re: How to downgrade to 4.3?

SZLevente — Sun, 05 Oct 2014 12:22:41 GMT

Already installed.

Re: How to downgrade to 4.3?

Thommo — Sun, 05 Oct 2014 12:32:27 GMT

So what exactly is the missing driver - The driver your image refers to is not from Sony - This is something made via members on XDA

Re: How to downgrade to 4.3?

SZLevente — Sun, 05 Oct 2014 13:03:25 GMT

And what should i do? Install only flashmode and fastboot driver then try to flash the tft?

I've never flashed before. Pls help
