I recently upgraded my SGS2(India) to JB 4.1.2. via Kies. Post upgrade the SGS2 codes do not run . When I enter *#1234# I get "Connection or invalid MMI code" No other code runs including *#06# which returns "Unknown Application" . Codes ran fine prior to the update (4.0.4) The Phone is original purchased in India (Official unlocked version) I have run three upgrades earlier since purchase. The latest JB seems to caused the problem. Help is welcome please.
