hello ,
before like 2 months ago here in jordan they lunch 4G, but all samsung device doesnt support 4G.
the solution was go to samsung custmer service to make a software update ( which is 4.4.2 ) that let us able to use 4G here
i want to have a copy from this software since i want to try android Lolipop on my device , and as samsung custmer service here told me that if i upgrade to newer frimware 99% i will lose 4G again
and will need to go back to them for downgrade software
and i coudnt find this frimware on sammobile

hope i can find it here , there a screenshot from my device

Thanks
