I have a little problem. I want to give a hard reset to rooted LG Optimus Sol which was initially blocked in Vodafone and I unlocked it at a service to work with all networks. Can you tell me if I hard reset the phone will become locked again in Vodafone? I want to do this because the phone does not connect in data storage mode and the bluetooth does not work and in some moments has a very big lag. You can tell me if I hard reset will install all the default programs on the phone they had originally? Or is another posibility to reinstall the factory software without being locked again in vodafone? I searched the forums but some said that the phone will be locked again and others say that will remain unlocked. Please I really need the help.
