Downgrading from 4.4.2 to 4.3

Hello People,

I have just bought a samsung galaxy s3 neo (GT-I9301I)
It came with pre-installed andoird 4.4.2, but I would like to downgrade it to 4.3

Can someone advice me please (how ot do it, where to get the proper version of 4.3 and so on..)

Main reason for downgrading is that I cannot use LEAP WI-FI. I tried to find solutions but none of them work. So if that can be solved I would even keep the 4.4.2.

Please Help :)

PS: the phone is not rooted

Thanks a lot.
 
Not sure about the neo, but other versions of the s3 a downgrade will brick the device. A downgrade of the ROM is OK but downgrading the firmware (which includes bootloader and modem) will permanently brick the phone.
 
If it is stock 4.4.2 downgrading to an older stock will hard brick. Flashing a stock 4.3 system img (without the bootloader or modem) will cause a soft brick.

As far as I know your only option is to root and install a custom 4.3 rom.
 
Thanks for the replies people.
I've been reading a lot the last 2-3 days and I've decided not to mess up the phone. Most of the tries there ended up with bricked devices.
Besides I really dont know much about the Android ..

Thank you one more time and enjoy :)
Have nice days,months and lives.

In my opinion, the bootloader has been locked and I couldn't install TWRP and CM11 any longer. I followed the link,
Sprint Galaxy S3 Android 4.4.2 KitKat root - L710VPUDND8 from OTA | AndroMods
However, my phone is still unrooted according to Root Checker even after the superSU has been installed.

That's for the sprint s3. I have a sprint s3 L710 on nd8 4.4.2. And it is rooted and I flash Roms all the time. If you have the model L 710 then why don't you just use towel root? Then use flashify to install recovery. Both are apps and no computer needed
That link you put up was for sph l710, is that your model? If it is then no your boot loader is not locked. Even if it was that doesn't stop you from rooting. It only prevents flashing custom recovery, but with root and xposed framework you can add anything found in custom Roms anyways.
