So it's a special version of the SGS3.
And holding Volume DOWN + HOME + POWER keys does not work any more?
Have a look here: Samsung Galaxy S III I9300, I9305 Galaxy S III I9305 (4G LTE + 2GB RAM) > Q&A, Help & Troubleshooting > [Q] Rooting Galaxy S III SCL21.
There are some useful links to hopefully fix your bricked phone.
Else you may ask in the Samsung Galaxy S III I9300, I9305 Galaxy S III > Q&A, Help & Troubleshooting > [HELP THREAD] Galaxy S3 Ask any question. thread ... but it's originally for the international variants of the S3.
Good luck :fingers-crossed:

If neither download mode nor recovery mode is working, your device is hard-bricked.
AFAIK only a mainboard replacement can fix this.
But ask in the linked threads/forums before spending the money for a hardware replacement in a service center.
If you are still on warranty, feel lucky

[Completed] how to get 4g in samsung s3 19300 ?

samsung s3 19300
2gb ram

Hi there and welcome to Assist,
Specific Galaxy S3 models rolled out with 4G support (i.e. the I9305), so I don't think that the I9300 can support 4G, because you need obviously some kind of a special chip to use it.
It's an hardware issue, not software as it can't be supported via any kind of app I think.
You'll have to create an account to post in the main forums if you have any other questions.
