I install the ftf of the lt28h on my phone but know he wont get 3g signal on any operator , only 2g and the configuration in the test menu says this
-working bands : no available speech code
I reinstall the stock firmware and its the same problem (works fine before UPDATE) , thanks to all for the future help
