Go to www.sammobile.com download your stock firmware and flash through odin.

[Q] hi, i'm new here. Downgrade or..?

I make update at my galaxy s3 to android 4.3. My question is, i can make downgrade to 4.1.2 , or can i instal custom rom(4.1.2, miui ro.)?. Please help or give a answer please

Hello.. Being updated to the latest firmware version is better than leave you left behind. By the way, you may downgrade to the previous version by flashing it via Odin. MIUI is custom ROM and not recommended for most user since it could make your warranty void. Thanks

If i stay at 4.3 i can istall custom room (4.1.2)?

If you flash with ODIN, yes. Just keep your modem XXEMG4 or greater, and you won't have a problem with whatever ROM you choose to run.
How to keep modem i have ugmk6?
